Q: Description of the disease (onset time, main symptoms, hospital, etc.): I have been suffering from diabetes for more than 10 years, now with Novolin 30R injection, 22 in the morning, 8 in the evening. Often appear the following situation: before dinner, blood sugar is basically normal (such as 7 at 18:00), before going to bed, blood sugar is normal (such as 23:00 blood sugar is 3.9), when I wake up in the morning (such as 6:20 blood sugar is 6.2), but after 1 hour But after an hour, the same fasting (e.g., fasting blood sugar becomes 10 at 7:30 am), and the blood sugar is higher if the time is longer, what is the reason? Is it also a dawn phenomenon or Sumo reaction (but both dawn phenomenon and Sumo reaction are high blood sugar in the morning, I have such a change in the morning at the same time)? A: In every morning, the level of some hormones in the body will rise, and all these hormones have the effect of raising blood sugar, only insulin is the hormone that lowers blood sugar, if the level of insulin in the body is insufficient, there will be a rise in blood sugar. In order to avoid this situation, you need to develop a regular habit of life, inject insulin at 6-7 am and then have breakfast. Q: So this phenomenon does not exist in all diabetics, right? Is there an individual difference? My insulin dose in the morning is relatively high because I have this phenomenon? In this case, do I not need to adjust my dose? Thank you, Dr. Xu! A: This condition exists in everyone, so the insulin dose is more in the morning and less in the evening. If you follow the normal rest time, fasting blood sugar at 6-7 am is below 7, then inject insulin, have breakfast, and blood sugar 2 hours after meal is below 10mmol/l, you don’t need to adjust the dose.
