Understanding Low Blood Sugar

JANUVIA (jah-NEW-vee-ah) is a once-daily prescription pill that, along with diet and exercise, helps lower blood sugar levels in adults with type 2 diabetes. JANUVIA should not be used in patients with type 1 diabetes or with diabetic ketoacidosis (increased ketones in the blood or urine). If you have had pancreatitis (inflammation of the pancreas), it is not known if you have a higher chance of getting it while taking JANUVIA. IMPORTANT SAFETY INFORMATION Serious side effects can happen in people who take JANUVIA, including pancreatitis, which may be severe and lead to death. Before you start taking JANUVIA, tell your doctor if you've ever had pancreatitis. Stop taking JANUVIA and call your doctor right away if you have pain in your stomach area (abdomen) that is severe and will not go away. The pain may be felt going from your abdomen through to your back. The pain may happen with or without vomiting. These may be symptoms of pancreatitis. Before you start taking JANUVIA, tell your doctor if you have ever had heart failure (your heart does not pump blood well enough) or have problems with your kidneys. Contact your doctor right away if you have increasing shortness of breath or t Continue reading >>

    Why test blood sugar 2 hours after eating?

    I am new here. As newly diagnosed I have a LOT to learn..but what brought me here first was a question about testing blood sugar after eating. First..a quick intro..I recently had an A1c result of 6.3. That was higher than my previous A1c that was a year or so ago, that was 5. 'something' & that one a year or so ago was higher that one I had before it. So..basically the A1c has gone up over the years. My fasting blood sugar this time was 102, I don;t know previously. So, anyway, at my appt 2 days ago, the doc said she wanted me to start metformin 500mg once a day. Lose weight, eat better etc. of course. She ordered a meter for me & all that. I will be checking at least daily, 2 hours after meals. I have been doing more, since I want to see what my levels are at other times too. AT least for now. She did not use the word 'diabetes' or 'pre-diabetes' so nit sure where I fall. The doc did say I had 'insulin resistance' whatever that indicates. The nurse said if I am on medication, it is 'diabetes'.
    Ok..so...The testing 2 hours after eating is what I am wondering about. WHY 2 hours? Why not 3 or 4 etc? Wouldn't your blood sugar continue to rise as your food is digesting? Or are our stomachs supposed to be empty after 2 hours? I have GI problems, and know by tests that I digest slow...on the borderline of 'too slow'. Would this have an affect of my blood sugar levels? I would like to test when my blood sugar is likely to be at the highest, at least in the beginning. With an A1c of 6.3 my doc said my average blood sugar has been 147. But we don't know if that is because of highs & lows averaging out or because it hover around that 147 level etc. I have been having symptoms that could be associated with diabetes - dizziness, hunger, blurred vision, headaches, nausea, fatigue etc. Could be something else too. So how to I determine when my blood sugar is likely to be at the highest? Wouldn't it be different for each person?
    Thank you so much for your guidance! I am sure I will have more questions soon!

    Welcome and great questions too. Read this link. http://www.phlaunt.com/diabetes/
    Testing after 2 hours to see how that meal affects your blood sugar and also see when it peaks. Some foods can peak for me 4,6,7,8 hours after I've eaten it. Knowing this helps me know how much and when to dose for it.
    I am type 1 so I must use insulin.
    I bet after you read the link I just gave you, it wil answer several questions. It is a must read for all diabetics. I've been diabetic for 26 years and I am still learning.
    I hope I have answered your question. Read - read - and read some more. Ask dozens of question...then read some more. We will never know it all, but I sure as heck intend to learn as much or more than my Dr. This is my disease, not my Dr.s. It is my responsibility to know all I can about it and how it affects me.
    This is a great forum to learn and share and I'm so glad you found us.
    Good luck and I look forward to hearing from you again...soon.
    By the way, your symptoms do sound very much like diabetes.

    Testing 2 hours after eating is considered a good indication of how well diabetes is being controlled because, with non-diabetics, blood glucose has returned to normal 2 hours after a meal. Blood glucose always spikes after a meal, and it comes down as soon as the enough stored insulin is mobilised and new insulin is produced to achieve this. This mechanism doesn't work properly with T2 diabetics, and the 2 hour post-meal test is a good indicator of how well the problem is being managed.
    The graph below shows what happens to the blood glucose of non-diabetics after meals. As you can see, 2 hours after eating, blood glucose is almost down to where it was before the meal.
