Blood sugar fluctuates at any time, so people's blood sugar values are different at different times of the day. "Five-point" blood sugar measurement refers to measuring blood sugar at five time points. These five time points include: fasting and 30 minutes after a meal. , one hour after a meal, two hours after a meal, three hours after a meal. There are five time points for blood glucose monitoring that need to be grasped.
Normal people's "five o'clock" blood sugar gradually rises. In the early stages of diabetes, blood sugar changes irregularly. Generally, blood sugar is normal during fasting and two hours after a meal, while blood sugar at 30 minutes and 60 minutes after a meal is normal. On the high side, or on the low side two hours and three hours after a meal. If the above situation occurs, it is recommended that you go to the hospital for an insulin test to determine whether you really have diabetes by comparing the blood sugar level with the peaks and troughs of insulin secretion.
Why do diabetics experience hypoglycemia before meals? After some patients develop diabetes, the pancreatic islet cells still have a certain ability to secrete, but the peak of insulin secretion is delayed. It is the period after the first meal and before the second meal. At this time, the actual blood sugar is already very low, and at this time, because insulin is When delayed secretion reaches its peak, blood sugar itself is at its lowest point. Coupled with the peak of insulin, persistent hypoglycemia will occur, manifesting as hunger, sweating, dizziness, palpitation, etc.
If patients are not clear about their condition, they will consciously eat more and increase calories, which will aggravate the development of diabetes. As the disease continues to progress, pancreatic islet cell damage intensifies, insulin secretion gradually decreases, or insulin resistance further worsens. At this time, hypoglycemia is replaced by sustained hyperglycemia, and diabetes becomes more serious, making treatment more difficult. It also puts the patient at increased risk.
