Help: Why is fasting blood sugar higher than postprandial blood sugar in the morning? Answer: It’s reactive hyperglycemia after hypoglycemia, you can’t increase the dosage anymore! First of all: your insulin before dinner should be reduced, at least by 4u. If you still add insulin, it is very dangerous, and you may “pass” during sleep because of hypoglycemia, without knowing it. Reason: The human body has a protective mechanism, after the occurrence of hypoglycemia, the body’s glucagon will increase, so that the blood sugar rises. However, if hypoglycemia is repeated, the body’s response mechanism slowly declines and tolerates hypoglycemia, and people slowly become stupid (because irreversible damage is caused to brain cells). It is also important to note: it is also necessary to test the blood sugar two hours after breakfast and lunch. Assuming that the blood sugar after breakfast or after lunch is also pressed low, then the insulin before breakfast needs to be reduced as well. Note: Never force a sick person to repeatedly add meals to overcome hypoglycemia! Blood sugar control must not come at the cost of hypoglycemia! Remember not to increase the dosage as soon as the blood sugar is high! The cause should be analyzed first.
