Post prandial blood sugar normal range during pregnancy

25 Printable Blood Sugar Charts [Normal, High, Low]

Regular testing their blood sugar at home is something people with diabetes must do. Also known as blood glucose, blood sugar refers to the sugar transported via the bloodstream that supplies energy to all body cells. The food we eat makes up the sugar in our body. Using a blood sugar chart, diabetes patients can perform a blood sugar test. The amount of glucose in your blood is what a blood sugar test measures. Usually, carbohydrate foods make the glucose in our blood. The main source of energy used by the body is glucose. The cells of your body use the glucose with the help a hormone called insulin. When the glucose amount in the blood rises, insulin produces in the pancreas and then releases into the blood.

How well you control your blood sugar levels determines the success of your diabetes treatment. If you’ve recently got tested for blood sugar levels, use blood sugar chart to control your blood sugar. Over time, you’ll understand how sugar level fluctuates and how you can manage the condition. Depending on the test type, descriptions of blood sugar values in mg/dl are what the chart provides.

The three categories mentioned on the chart are normal, early diabetes and established diabetes while the test types include Glucose Tolerance, post-prandial, random blood, and fasting sugar. Finally, the ranges on the chart include the minimum value, the maximum value and value two hours after consuming glucose. Let’s now take a detailed look at blood sugar test and blood sugar chart.

Blood Sugar Charts

Understanding the test and chart of blood sugar

Before we discuss blood sugar test and blood sugar chart, it’s important to understand blood sugar first. Serving as energy for both plants and animals, glucose is a form of sugar. Normal levels are maintained with the help of a hormone that pancreas produces. That hormone is known as insulin. Health complications such as kidney disease, heart disease, and blindness are what high or uncontrolled sugar levels can lead to. Also, hyperglycemia occurs when the concentration of glucose in the blood increases. The best way to control glucose in the blood and blood sugar levels is using blood sugar chart and test. With the help of the chart and test, you can avoid a lot of health complications.

A blood sugar test reveals the blood sugar level of an individual. Somewhere between 72 mg/dl and 108 mg/dl is the normal blood glucose level of a healthy person. However, the normal blood glucose level depends on the individual. Generally, around 72 mg/dl is the blood sugar level in humans. However, the blood sugar level may temporarily increase to 140 mg/dl after a meal: this is a normal range. How well your diabetes program of exercising, meal planning, and medication (if required) is working to keep you range normal is what blood sugar testing helps you to determine. The closer you keep your blood sugar level to normal, the greater will be your chances of avoiding health complications such as nerve disease, blindness and kidney disease.

In order to find out the blood sugar levels of a person and whether he or she has diabetes, a blood sugar levels chart is used. Normal blood sugar chart outlines the normal blood sugar ranges for a diabetic and non-diabetic person. In order to determine what the health target of a person should be, a physician uses a blood sugar chart. Furthermore, the chart is used by the patient or physician to manage the blood glucose condition.

During the day, the levels may drop and rise. This is a normal occurrence. However, your blood sugar levels may indicate problems if they fluctuate dramatically. Significant physical symptoms are what dramatic blood sugar levels have. Furthermore, they’ll increase the risk of complications related to diabetes. Before, you get your blood sugar tested or start using blood sugar chart, it’s important for you to know what each blood sugar test type does.

Blood glucose, or blood sugar, is a very important source of energy for our bodies. It provides nutrients to the body’s organs, muscles and the nervous system. Glucose arrives in the body from the food you eat every day, with the absorption of glucose regulated by the small intestine, pancreas and liver.

Blood Sugar Normal Range

The normal range of blood sugar varies depending on the different laboratories that conduct tests. There are many factors playing a role in an individual’s blood sugar levels.And the normal levels may be slightly different in different occasions.

1. Normal Fasting Blood Sugar

An individual’s fasting blood sugar is measured when they first wake up in the morning. The idea is to get an estimation before any food is consumed. If your blood sugar levels are between 70 mg/dl (3.9 mmol/L) and 92 mg/dl (5.0 mmol/L) then you are at a normal fasting blood sugar level. A majority of research indicates that anyone with blood sugar levels in this range is not at risk of developing diabetes for at least another decade or two. If the blood sugar level is going above 92 mg/dl, the risk of diabetes begins to increase rapidly. Some doctors even consider blood sugar levels below 100 mg/dl (5.6 mmol/L) as normal.

2. Post-Meal or Postprandial Blood Sugar

This measures the blood sugar levels an hour or two after a meal is consumed. No matter what a person eats for his or her meal, the blood sugar level should not go above 120 mg/dl (6.6 mmol/L). For a majority of people, this level will not rise above 100 mg/dl after meals.

Individuals with diabetes are at greater risk when their blood sugar levels increase. For these people, keeping blood sugar between 4 to 7 mmol/L is vital before meals. For an after-meal level, blood sugar should not go above 9 mmol/L if you have type I diabetes, or above 8.5 if you have type II diabetes.

3. Normal Blood Sugars During Pregnancy

The blood sugar normal range during pregnancy is lower than other people, due to the dilution of blood sugar resulting from higher blood volume in pregnant women. A majority of research shows that the blood sugar range for a normal pregnant woman is

  • between 70 to 79 mg/dl at fasting;
  • between 109 and 132 mg/dl an hour after meals;
  • and between 99 to 110 mg/dl two hours after a meal.

If you are pregnant but also have diabetes, make sure your blood sugar levels at fasting are 79 mg/dl or lower, with the one hour and two hour after-meals level at 122 mg/dl and 110 mg/dl respectively.

Abnormalities in Blood Sugar Levels

With the blood sugar normal range discussed above, it is time to look at the types of abnormalities people experience in their blood sugar levels.

Low Blood Sugar

Low blood sugar occurs when the blood glucose levels in the body drop to below 70 mg/dl (3.9 mmol/L). There are risks associated with lower blood sugar levels, such as the potentially fatal hypoglycemia. If you are worried about low blood sugar, keep an eye out for symptoms such as lethargic feelings, impaired mental functions, constant irritability, shaking, twitching, weakness in your arms or leg muscles, a pale complexion, excessive sweating and complete loss of consciousness.

High Blood Sugar

Similar to low blood sugar, high blood sugar involves health risks for both the short and long-term. If a person’s blood sugar levels are constantly high, it leads to appetite suppression and other issues. If this hyperglycemia is long-term, it can lead to other diseases such as heart disease, eye problems, kidney failure, nerve damage and more. Consistent high blood sugar most often leads to diabetes.

How to Tell If Someone Has Diabetes

Diabetes is a very serious illness that has immediate and long-term health consequences. However, people are often unaware of how to diagnose diabetes in themselves or their loved ones.

Tests to Diagnose Diabetes in Someone

There are two main tests performed by doctors to test the blood glucose in the body, thereby discovering if you are suffering from pre-diabetes or diabetes. These tests are the fasting plasma glucose test (FPG) and the oral glucose tolerance test (OGTT).

The FPG test is a test of your blood to understand the level of sugar in your body after you have not eaten anything for at least eight hours. If the fasting blood glucose level is at 100 to 125 mg/dl, a person is likely to have pre-diabetes. If the level is 126 mg/dl or above, they already suffer from full-blown diabetes.

The OGTT involves measuring an individual’s blood sugar level by eating nothing for at least two hours and then consuming some beverage rich in glucose. If the blood sugar level is between 140 mg/dl to 199 mg/dl then they are suffering from pre-diabetes. If the level reaches 200 mg/dl or higher, they have diabetes.

As with any tests, these blood sugar tests are not 100% accurate. For that reason, if anyone measures in a range that outside the blood sugar normal range, the test is taken again at a different day to confirm the results. According to the American Diabetes Association, the FPG test is easier to perform, quicker and costs less money.

Test Your Blood Sugar at Home

If you do not have the time or money to visit a doctor to test your blood sugar, there are some home methods to check whether you are in the blood sugar normal range.

  • Using Your Fingertips: Take a small but sharp needle and prick your finger. Place the resulting blood onto a test strip. This test strip is then placed on a meter that indicates blood sugar levels. These results come in less than 15 seconds, allowing you to perform multiple tests on different days to get a more accurate assessment. Meters are also available that provide you with your average blood sugar levels over an extended period of time. These meters even come with charts and graphs to indicate past results. Blood sugar meters and strips are readily available at all major pharmacy locations.
  • Other Meter Tests: These tests are not exclusive to blood from the fingertip. Other parts of the body, such as your arm, forearm, thumb and thighs are sometimes used for testing. These results are sometimes different from the fingertip tests. If you want a more accurate assessment, use different meters on multiple days and take the average of the results. However, fingertip readings are said to come more quickly, and they are often more accurate for people who suffer from hypoglycemia.

Is My Blood Sugar Normal?

“Is my blood sugar normal?” seems like a simple question – but it’s not! The answer can vary dramatically based on your situation. Let’s look at some of the factors to consider. Please remember: you should figure out your personal goals in consultation with your doctor.

In This Section

Normal Blood Sugar in Diabetic vs. Non-Diabetic

First, a quick note on how we measure blood sugar. In the USA, blood sugars are measured by weight in milligrams per deciliter, abbreviated as mg/dL. Most everyone else uses millimole per liter, abbreviated mmol. If you are in the USA, look at the big numbers, most everyone else look at the small numbers.

In a person without diabetes, blood sugars tend to stay between 70 and 100 mg/dL (3.8 and 5.5 mmol). After a meal, blood sugars can rise up to 120 mg/dL or 6.7 mmol. It will typically fall back into the normal range within two hours.

These are normal blood sugars in someone without diabetes. Source: Thriving with Diabetes

In a person with diabetes, the story is much more complex:

3.8 mmol to 7.7 mmol

7.7 mmol to 10 mmol

Normal Waking Blood Sugar (or Fasting Blood Sugar)

Ideally, everyone with diabetes will wake up with blood sugars in the normal range. However, many people experience what is called the “dawn phenomenon.” As the body prepares to wake and start moving, it releases stored sugar into the blood. This can cause a moderate spike in blood sugar. You can read How to Fix High Morning Blood Sugars for tips on how to improve these numbers.

To confirm if this is happening to you, you can wake up in the middle of the night and check your blood sugar. If it’s in the normal range then but high after waking, this is probably the cause. If the spike is small and goes away quickly, then it’s likely nothing to worry about (check with your doctor). The spike from dawn phenomenon is often less than the one you get from eating a typical meal.

Morning blood sugars can also be impacted by what happened the night before. The amount of carbohydrates you ate and how much medicine you took can have an impact. Even stressful night of tossing and turning can lead to high blood sugars. Learning what causes your blood sugars to rise and fall by checking your blood sugars strategically is the key to figuring out why your blood sugars are what they are in the morning.

Normal Blood Sugars After Meals (or Post-Prandial Blood Sugar)

The chart below compares post-meal blood sugars in a typical person with diabetes and someone without diabetes. Most diabetes organizations recommend keeping your post-meal rise below 180 mg/dL or 10 mmol.

So is 200 mg/dL or 11 mmol a surprisingly high blood sugar an hour after a meal? If you were at 150 mg/dL or 8.3 mmol before you began eating, then probably not. Your meal only caused a modest bump of 50 mg/dL or 2.8 mmol. That would be perfectly reasonable in someone with a perfectly functioning pancreas!

To know whether a blood sugar is what one would expect, it’s important to understand where you started. If you would like to reduce your blood sugars after meals, read How to Start a Low-Carb Diabetes Diet.

What Blood Sugar Levels Are Healthy?

This is an area of some debate. The long-term studies show that the risk of complications drop off dramatically when an HbA1c is lower than 7%, an estimated average blood glucose of 154 mg/dL or 8.6 mmol. It continues to drop until it’s below 6%, an average blood sugar of 126 mg/dL or 7 mmol. There are many people who strive for lower targets, but there is not a lot of research outlining the benefits of that approach yet.

One challenge is that studies of A1c are just looking at averages. In reality, there seems to be a huge difference in risk of complications based on genetics. There are many people who have lived thirty or forty years with type 1 diabetes running high blood sugars almost continuously and have no complications. There are others who have had nearly perfect blood sugars that still get complications. But for most people, it’s safe to say that striving for an HbA1c of below 7% and probably below 6.5% is a realistic goal for staying healthy.

There are exceptions, of course. Doctors might often recommend higher targets for those that can’t sense low blood sugars, are elderly or have some other health conditions. The reasoning is that the health risks of striving for lower targets may be outweighed by the risks of doing so. For example, most complications take decades to appear. If someone is diagnosed with type 2 diabetes at 90, there’s almost no chance of living to see those complications. So a doctor might prescribe less intensive therapies.

There is also a lot of research suggesting that the total time you spend in a health range is more important than your A1c. For example, if your low A1c comes from a lot of severe lows balancing out highs, this is less good than just having more steady blood sugars near the normal range.

A Note About Meter Accuracy

In the USA, a meter can be approved for sale so long as the results are consistently within 20% of the right number. That means that if your blood sugar was 180 mg/dL or 10 mmol, than a result of 216 mg/dL (12 mmol) or 144 mg/dL (8 mmol) would still be considered accurate. In practice, most meters are more accurate than that, but even an expensive hospital blood test using calibrated equipment has a 10% margin of error.

So don’t automatically panic if you check your blood sugar and it’s 140 mg/dL (7.7 mmol) and a few minutes later it’s 150 mg/dL (8.3 mmol), a change of under 10 mg/dL or 1 mmol. This may just be the meter. Look for trends over time to truly understand what’s happening.

You can check out this chart comparing blood glucose meter accuracy. Keep in mind that this study is not current and, unfortunately, that no one has published more current data. (There should be some independent group testing meter accuracy in the real world, but it just isn’t happening… yet.)

Is My Blood Sugar Normal?

So there you have it: a long and winding answer to what seems like a simple question! And remember: please consult your doctor to understand what healthy blood sugars are for you.

Post prandial blood sugar normal range during pregnancy

AVERAGE BLOOD SUGARS IN NORMAL PREGNANT WOMEN

Fasting: 70.9 ± 7.8 mg/dl (3.94 mmol/L ± .43)

One Hour Post Meal: 108.9 ± 12.9 mg/dl (6.05 ± .72 mmol/L)

Two Hours Post Meal: 99.3 ±10.2 mg/dl (5.52 ± .57 mmol/L )

Fasting: 79 mg/dl (4.4 mmol/L)

One Hour After Meals: 122 mg/dl (6.8 mmol/L)

Two Hours After Meals: 110 m/gdl (6.1 mmol/L)

The challenge during pregnancy, of course, is to lower blood sugar without going too low because hypos can also cause problems for the fetus. In addition, the solution that works so well for non-pregnant people–cutting way back on carbs–raises issues.

"abnormal blood sugars in pregnancy almost always point to the pre-existence of abnormal sugars in the non-pregnant state that were missed by your doctor"

I'm in Europe so perhaps that is why I am stumbling on this "2 hour reading only" criteria.

Lower is better, BUT, lowering sugars in a way that starts to feel like self-denial can backfire. For a while you'll be enthusiastic, but blood sugar control has to be for life, and if you are too stringent, you may end up burning out a couple years down the line and when that happens it is very easy to lose control.

Thanks Jenny, and thank you for all the info.

"Blood sugar control is particularly important in pregnancy because a fetus that is exposed to continually high blood sugars will experience significant changes in the way that its genes express which will affect its blood sugar metabolism for the rest of its life."

The best way to find out if you have abnormal blood sugar is to follow the instructions you'll find HERE.

I am concerned that your worries about the epigenetic effects of ketosis during gestation may be misplaced. Can you provide the citations for this, please? I have looked at the main site and have not been able to find them. Thanks.

The main data we have about starvation and its impact on diabetes in offspring is the WWII Dutch Famine study: http://www.ncbi.nlm.nih.gov/pubmed/9449872?dopt=Abstract.

"Even the most enthusiastic of the low carb diet doctors do not advise eating at ketogenic levels during pregnancy."

I am T1 and 27 weeks pregnant and normally agree with anybody recommending tight control; however in this case I have to say that these targets are neither realistic nor reasonable. It might be workable for GD patients who

are able to manage on diet/exercise. But it's not possible – and could even

be unsafe – for women using exogenous insulin.

realized that if I was under 7.8 at PP+1, I was guaranteed a hypo at PP+2 and then another hypo at PP+3.

article is arguing is too high) has been to watch my blood sugar like a

hawk for up to five hours after eating and catch hypos before they hit. This is only possible on the days when I work from home.

life-threatening, which is not good for either mum or baby. If PP+3/4/5 is 'normal', then PP+1 is abnormally high and PP+2 is high – but there is little chance of hypos.

work but I also have to balance risks. And based on my own personal experiences thus far, I have to say I am more afraid of the risks posed by trying to reach the blood sugar targets proposed in this article.

In my household, we have been eating very low-carb for nine years. We have not encountered any problems and certainly have seen no sign of T3 (BTW this is the first time I have heard that this is a problem associated with LCHF). My eleven year old son eats some carbs but no sugar. My two year old daughter has no taste for carbs which I think is because she is the product of a very low carb gestation. She is growing like a weed and is very precocious in every way.

I'm going to resist the temptation to debate Paleo here, as that isn't what my blog readers come here to discuss.

When you said T3, I thought you meant Type 3. Although we have had no problems with thyroid, I believe there is evidence that reducing carbs does result in lower thyroid output. There is a physiological explanation for that. A normal blood sugar represents about a teaspoon of glucose in the circulation. The body wants to keep that in a very tight range. When you eat a carb heavy meal, you create a "metabolic emergency" with the sudden influx of glucose. Your body responds by secreting insulin to push the glucose into the cells to be burned for energy, to convert excess glucose to fat in the liver and to push the fat into the fat cells where it is out of the way and won't interfere with the burning off of the glucose. In that scenario, increased T3 is useful in terms of increasing the rate at which the glucose is burned. Doing this on a chronic basis, in susceptible people, leads to burn out of the beta cells. I think that the thyroid burns out for the same reason. If you stop eating carbs, the thyroid responds by lowering T3 production. For some people, whose thyroid capacity has been damaged, T3 will go too low when the stimulus of high carbs is removed. It doesn't happen to everyone and it's not an indication that carbs are needed. It's just another indication that high-carb diets are not healthy.

I'd be the last person to argue for high carb diets.

I had a look at the link and I agree it is a sensible approach to getting blood sugar under control. The one concern I would have, though, is that raising carb intake to the threshold where blood sugar starts to rise may be problematic in the long run. Blood sugar may be normal but at the cost of continuing pancreatic beta cell burn out. Once somebody has been diagnosed with T2, they have lost about half their beta cell capacity. The approach they take from that point on should be to maximally preserve beta cells by not taxing them with the need to produce any more insulin than absolutely necessary. That means minimal carbs (I don't include non-starchy vegetables in that, btw). Beta cell preservation is also the rationale for introducing insulin early in the conventional management of T2.

I have not seen any research that convinces me that beta cells "burn out" just by secreting insulin. Instead, what seems to happen is that beta cells in people with Type 2 succumb to glucotoxicity because people with Type 2 are encouraged to maintain blood sugar levels that spend hours a day in the high 100s which is the range where glucotoxicity kicks in.

It is important to realize that the amount of carbohydrate is not an exact amount. The USDA allow the amount on the label to be within plus or minus 20%. So if it says 100 grams it could be anyplace between 80 g and 120 g. That's a big difference if you are taking insulin. Who measures any one package? Maybe a batch and who knows how often and probably only a calculation so there is lots of room for error. The only way you can know is to measure what it does to your blood glucose.

I agree with you if you stay away from all packaged foods you don't have to worry about any labels but if you read Bernsteins form and others it seems that a lot of readers have a biblical attitude towards them that is that they are exact and they need to understand that they are not exact but an estimation at best.

Jenny, I'm sorry that this question is off topic, but I'm not sure where else to ask it.

Chicken wings without a floury coating should have no impact on your blood sugar at all, but the fast food ones are usually full of flour. So that result doesn't make much sense. Did you repeat your meter readings to make sure it wasn't a bad strip?

Jenny, I apologize again for continuing this off-topic intrusion, but it's getting interesting to me. I have also been asking Seth Roberts (also off-topic on his blog) about my binges . I mean self-experiments here, with more details about my 200-point drop in blood sugars. My doctors would be shocked, but I'm going to repeat this experiment to check the results. Oh, and the chicken wings were plain, with no breading or anything else, except for being deep-fried in peanut oil. And, yeah, I know that this goes against all medical advice, but a 200-point drop im blood sugar is amazing to me.

Jim, If you can survive a 200 point drop in your blood sugar it is WAY too high, and you need to give up looking for magical solutions like this one and get the help you need–before you irreversibly damage your organs.

Jenny, I love your blog and I am also a fan of Dr. Js. You are both on the same side fighting the same fight. It was a great back and forth. Obviously Dr. J is a reader of yours. Please check out his web and the movie they shot of his work with 2 Indigenous Tribes in Canada. I am forwarding these comment threads to Dr. Bernstein and Dr. Ron Rosedale. They should enjoy them. Lastly Jenny, do you have any desire to present or attend the Ancestral Health Symposium in 2012? You are quite often mentioned in the Paleo blogosphere with regards to your brilliant work and breakdowns. With your anthro background, it would be fun to see you there.

"As an anthropologist what most fascinates me is the way in which ALL ways of eating take on religious overtones and spark cult behaviors in those who adopt them. This doesn't benefit any of us whose concern is the restoration of health!"

Jenny, Paul is an astrophysicist and an entrepreneur. He is not an MD. He gives reasons for why it should be 50gms, which are formed from his own experiences. But yes that is just a starting point.

I think 80 gms is about what is recommended in Life Without Bread book.

Ketones in the presence of normal blood sugars is a completely different condition from diabetic ketoacidosis which is what your endo is trying to treat.

Jenny, have you looked at The Barker Theory. It's on barkertheory.org. He has conducted studies for a long time. I recently saw a documentary he featured in, about some women in India, poor and underfed during pregnancy, and the incidence of their children ending up as thin T2s is very high. In fact, from what I know India has one of the highest rates of T2, yet not all are obese.

Sooz, No one has really investigated how far the the similarities go, metabolically, between ketogenic diets and starvation resulting in ketone formation, but I agree this is a concerning issue, and I would not recommend eating a ketogenic diet in pregnancy.

I know this post is several months old, but having just found out I have gestational diabetes a few weeks ago, I've been reading everything I find on the internet, and have read this several times. I did want to address something that Joyce mentioned about ketones. I'm new to GD, but I know that it is actually normal for pregnant women to have some ketones in their urine. Not all pregnant women do, but some do, and I'm not just referring to pregnant women with GDM, but sometimes there are low levels of ketones even in totally normal pregnancies. I haven't read why, but I have read several times that it's normal to have a little more than trace for some women.

Hi Jenny, just want to say I really appreciated this post. Some of the "normal" blood sugar charts out there are ridiculous. I've been testing my blood sugar with a family friend's meter (type 1, physician) because I was having hypoglycemic episodes at 24 weeks pregnant, and he was very concerned I had GDM. I haven't had the GTT yet, so I don't have a diagnosis there.

I'm 30 yrs old female, now I am pregnant 33 weeks,

My GTT is fasting 6.6 mgdl

After meal 2hr 7.7 mgdl

Then my scan report is my baby is bit heavy

And my family history is my mother have DM

Is it I high risk DM patient . I'm very confused now pls help me ,

Before pregnant my GTT was normal .

5.3 mmol/l (95 mg/dl) fasting, 5.7 (103) 1h and 5.1 (92) 2h postprandial.

I'm quite young, of normal weight and although I don't restrict carbohydrates, I'm on a relatively carb-conscious diet (would estimate having around 100-150g per day).

I'd like to comment on this post because this is a topic that really gets me: I wholeheartedly agree that a fetus' blood glucose environment likely has many implications for a child's health. And, like you point out, no one is willing to truly 'experiment' with pregnant human subjects. It is therefore very frustrating to me that there isn't there more intelligent thought and discussion on the topic.

thank you for your response earlier! My readings continued to be around 100 mg/dl for fasting glucose when I tested them. My antenatal clinic thought I didn't need extra surveillance and should only measure my values occasionally after the initial monitoring period. At ultrasounds and doctor appointments, I was told my baby seemed to be of normal size, which reassured me, and since I suspected having MODY2 (in which case the hyperglycaemia shouldn't be treated in case the foetus has the same mutation), I didn't follow a strict diet at all.

I know that a1c is not a reliable marker but from studies what seems to be the non diabetic average? How much does a1c increase during non diabetic pregnancy? Also the fasting and post meal numbers listed here do they apply just to everyday eating or the ogtt also ?

Holly, I'm not sure what the normal A1c is considered to be in pregnancy. Usually doctors just administer the ogtt and don't understand the impact of post-meal numbers, but I would assume that for pregnancy as in non-pregnant states the best results come from getting those numbers after meals, too.

while its good to know what normal is, i'm afraid you're off base with your suggestion of changing the "target" for pregnancy, which would mean medicating large numbers of women. to do this you need not only to know what "normal" is, but what level of abnormal is detrimental. you have not put forth any evidence that medicating women to acheive such levels will produce better outcomes at all, especially considering the very small difference in outcomes by pregnant women who are below the current treatment thresshold.

kisaria, It isn't "My" suggestion to change the target. It's the suggestion of those whose research I cited and of other experts who published commentary on that research.

What about Metformin during pregnancy—does it continue to be effective? I'm curious because as pregnancy progresses doesn't insulin resistance worsen?

Anna, I don't know the answer to that question. You would have to discuss Metformin with your OB/GYN. Years ago they took pregnant women off all meds except regular human insulin, which seems like good advice to me but I don't know what the practice standards are now.

addendum to last note: in addition to highly restrictive diets

Jenny, I just wanted to thank you for this blog. I was non-diabetic prior to pregnancy. I am now 14 weeks into my pregnancy. I wasn't feeling well one day so I went in to see my OBGYN. Since I was in there at 8 am and hadn't eaten anything she decided to see what my glucose was. She found it to be 135 mg/dl. She decided to schedule me for an OGTT the next day. My one hour was 183, 2 hour 171, and 3 hour 159. I don't remember what she said my fasting was. She's diagnosed me with GD and is treating me for it but wants to see me at a post delivery follow up for another OGTT, auntoantibodies check, c peptide levels, and a a1c reading. I'm not sure what she's looking for with those.

I am 27 week and today I had the OGTT. The results were a bit surprising: 90- fasting, 129 after 1 hour and 159 after 2 hours. To my understanding the value after 2 hours should normally be less than the value after 1 hour. Is that correct and if not could you give me any explanation? Thanks a lot in advance!

Galena, Mostly blood people will see higher sugars at I hour but not all. Blood sugar is very variable. Your liver may be dumping glucose for some reason–perhaps the physiological stress of the test. I wouldn't worry about it too much. Just see what the doctor suggests.

Thank you so much, Jenny! Yes, I will talk to my gynaecologist but he is not a specialist. To my understanding the glucose drink is something which should be absorbed very fast in the blood and the jump should be seen immediately, correct? As my mom has diabetes I asked her to measure my post meal sugar, 30 min, 1 h, 2 h. There was nothing like that, the numbers were declining, so for me this is a possible error. She checked me over 5 times. What do you think? Thank you so much again.

Thank you so much, Jenny! I will do so.

Have a great Sunday!

Now I'm 34 week pegnant lady. I done gtt test, there for the fasting blood suger I got 76.6 mg/dl. After 1st hour blood suger level is 230 mg/dl and after 2nd hour blood suger level is 216.00 mg/dl. Is that effected to my baby? Before 34 week I do not have this range. When doctor scans baby and tall she is ok. But I'm fear @ my blood suger. It will effect to my baby?
