I'm finding conflicting information on how long after you eat you should test you BG the second time. My mother says 1 hour, some sites say 2 hours, I found a couple of pages that says as soon as you finish eating. Help? (note I am having to go this on my own due to no insurance)

It all depends on how stable your numbers are overall. Since a doctor and I discovered that my average number after eating is usually well over 300, and many times in the 400s, 500s, and 600s, I take mine after eating. However, I take a 2 hour reading, too, to get a better idea of how my diabetes is doing later on. ANNE

Everyone is different. Our bodies all respond differently too. Our meals are also different from meal to meal and day to day. It is important for you to establish a base line for your B/S. I started by testing before I ate, then right after finishing, then one hour then two hours after eating. I did this a couple of times over the course of a few days, but gave me some good insight into how my body reacted. For the most part now, I test about an hour and a half after eating to get a good idea of how my body is responding to the food intake. And I now don't test that way everyday, but just often enough to keep tabs on what is going on.

Blood sugar should return to 'normal' 2 hours after eating.

Thank you so much for that imformation…I had no idea it should return to normal 2 hours after eating. Currently, and for a long time now, mine is extremely high right after eating and very very high 2 hours after eating. ANNE

you can do either one but waiting untill 2 hours gives you a better reading on how well you are controlling what and how much you eat. it should not be over 140 after 2 hours

annesmith 2011-11-22 22:59:47 -0600 Report

Thank you for that information. Here I thought it was pretty much normal to be in the 200 range up to 2 hours after eating…I was misinformed somewhere along the line …It feels so darned good to be on this site with this community…I used to have a "friend" that was type 2 diabetic, and he'd go around harassing other diabetics, saying a bunch of false information…glad I don't talk to him anymore…sincerely, ANNE

My doctor has specific times that he wants me to test. I feel that you should discuss this with your medical professional along with why he wants you to test at those times.

Most of us casually say "two hours after a meal" but more specifically, I've read two hours after you take the first bite of a meal. Another book I was reading stated that we should be careful to consume our entire meal in no more than one hour and test two hours after the first bite. My diabetic educator told me to do the preprandial test before I started cooking because even seeing/thinking about food can cause the BG to begin to rise.

Kevin's point is well taken also. Different foods cause the rise to be more or less sharp. Different people respond faster or slower. A little carefully planned extra testng over a few meals would give a good idea of what your pattern is, then use that to determine what your post prandial high is.

Below is an excerpt from a quiz that appeared if the lasted issue of dLife dBrief. This should answer your question.

Question: If you test your blood sugar before and after meals, the after meal (or postprandial) test should be:
Answer: Two hours after the start of the meal.
Postprandial testing measures blood glucose exactly two hours after the start of a meal. This helps you achieve the best control of your blood sugar levels and makes sure that your mealtime insulin is meeting your metabolic needs for the carbohydrates you consumed. After a meal, glucose concentrations change rapidly, so the more information you can attain from frequent self-monitoring of blood glucose is best.
Monitoring your blood sugar levels and keeping them as close to normal as you can is crucial in maintaining good diabetes control and reducing your risk of diabetes complications.

American Diabetes Association. ADA Standards of Medical Care in Diabetes. Diabetes Care 2010 Jan; 31 Suppl 1:S12-54.

You can see that the sources are authoritative and should answer your question on when to test after a meal.

It all depends on what you’re looking for. I used to test 2 hours after eating to see if my blood sugar wasn’t to high after eating. I now test my peaks after eating. I read somewhere that most people will peak about 1 hour after eating. It really all depends on what you eat but most of the time it will be approximately 1 hour. I like checking my peaks to see how high my blood sugar is going up after eating. After lunch I found that I peak about 25 minutes after eating so will test then. You must decide for yourself what is more important to you. If you want to try and keep your blood sugar from peaking too much then test about 1 hour. If you don’t care what your peak is, then use the 2 hour. I personally wouldn’t eat anything that spikes my blood sugar more than 50 points 2 hours after eating. I really like to keep my peaks below 40 points after eating. To help you decide, you might want to test at the 1 and 2 hour mark after eating to see what you prefer. Then use that time. Most of the time if you’re peaking a lot after eating it’s going to be high carb starchy foods like bread, pasta, potatoes and such. I try and not eat foods that have more than 5-6 net carbs per serving. What you do is up to you. I found by reducing carbs I don’t have to take meds any longer. Also eating lots of low carb vegetables will help with insulin resistance and drinking several glasses of water per day will also help.

Thank you, I do want to see what the foods do to my levels at peak so 1 hour it is. Now, to clarify, is that 1 hour from start of eating or from finish? I get confused on that too.

Kirla 2011-11-20 13:03:01 -0600 Report

I use after I eat. How I find my peak is to start testing about 30 minutes after eating and every 10 minutes. Your blood sugar should go up for several tests and when it drops you will know approximately when you peak. I found that in the morning I peak at about 1¼ hours after eating. For lunch I peak about 25 minutes after eating. Supper I peak about 1 hour after eating. Depending on what you eat it can change. I heard you might peak sooner if the meal has a lot of sugar or high carb starchy foods. I read that most people will peak about 1 hour after eating most of the time. So testing then should be ok. It all depends on what you can afford. I have insurance and they buy me all the test strips I need. I test about 7 –8 times a day and some days might test as much as 10-12 times or more. Every once in a while I will test again about 10-15 after my peak time just to make sure its going down or doesn’t go higher. I found that most of the time I pretty much eat the same foods for most meals most of the time so my peak times usually stay the same.

By testing a lot I found that low carb vegetables if eaten with some protein or fat doesn’t spike me too much. With out the protein or fat I will spike more than I like so I always try and eat some meat or an egg with my vegetables. I don’t eat high carb starchy foods so don’t have to worry about them. Meat and cheese doesn’t spike me too much so I always try and eat a vegetable with my meat. Mornings are the hardest. I found that I can’t eat much carbs of any kind in the morning. I usually will have a protein shake when I first get up and about 2 hours later will have a cup of coffee with some sunflower seeds and sometimes will eat a hard boiled egg. As long as I drank the protein shake earlier my snack doesn’t spike me much.

Testing and eating is what controlling our blood sugar is all about. I believe most people should test before and after each meal. If what you ate spikes you more than lets say 50 points then start looking for high carb starchy foods causing the spike. Either cut back on them or eliminate as much as possible. Me, I eliminated them. Most of the time my blood sugar doesn’t peak more than 30 points but this took me a while to do with lots of testing.

I believe eating low carb vegetables helps with insulin resistance so eating salads, broccoli, cauliflower, spinach, cabbage, cucumbers and such should be eaten most every day. Drinking 6-8 glasses of water or more also helps.

By eating my vegetables and drinking the water and cutting back or eliminating high carb starchy foods helped me bring down my blood sugar from the 300-400 range to almost normal numbers in about 6 weeks. A1C dropped from 14.1 to 5.9 in less than 4 months. Not everyone will have the success I did but that’s what I did and it worked. Most people I know who were able to control their blood sugar and get off meds all follow low carb diets. Its what I believe.

Forgot to say if you don’t have enough test strips to test all your meals everyday then test breakfast one day, lunch the next and dinner the next and so forth. I also like to test before I go to bed once in awhile and sometimes when I get to pee in the middle of the night I will test then. I pretty much know what my blood sugar is doing most of the time. I used to have numbers that were very high or at least they were high for me and I don’t ever want to go back to that.
