Is blood sugar of 10.3 after a meal high? You need to know the diagnostic criteria for diabetes

A normal person's blood sugar level after a meal should be less than 7.8. If it is too high, you should be careful about diabetes. If a diabetic patient's blood sugar level is always high after a meal, it will cause a lot of harm to the body. Timely blood sugar testing is of great significance and can also better regulate the condition.

1. Diagnostic criteria for diabetes:

The normal fasting blood sugar range is 3.15～6.19mmol/L, and the blood sugar 2 hours after meal is <7.8mmol/L. When the fasting blood sugar is ≥7.0mmol/L and the blood sugar 2 hours after meal is ≥11.1mmol/L, it is diabetes. If the fasting blood sugar is between 6.1mmol/L and 7.0mmol/L, it is called fasting blood sugar impairment. If fasting blood sugar is normal and postprandial blood sugar is between 7.8mmol/L and 11.1mmol/L, it is called impaired glucose tolerance. Impaired fasting blood sugar and decreased glucose tolerance can be seen as a transitional stage from normal to diabetes, but if treated properly, they can be reversed to normal. If not treated properly, it can develop into diabetes.

Normal blood sugar after a meal is less than 7.8.

2. The significance of self-monitoring of blood sugar

1. The benefits of self-monitoring blood sugar for diabetes control

If hyperglycemia or hypoglycemia is detected, timely adjustment of medications is required. Blood sugar levels directly reflect the actual degree of glucose metabolism disorder. Blood sugar control refers to the overall control of blood sugar throughout the day. Many factors can cause patients' blood sugar fluctuations, such as unreasonable diet, excessive drinking, improper exercise, drug effects (improper use of hypoglycemic drugs or other drugs), emotional fluctuations, stressful states (such as colds, fever, trauma, surgery, pregnancy, and other chronic diseases in the body, etc.)... The blood sugar of many patients can fluctuate all day long. Self-monitoring of blood sugar means understanding the fluctuations of blood sugar levels throughout the day. Blood sugar monitoring should include monitoring before and after meals and at night.

2. Monitoring blood sugar before and after meals is helpful in adjusting the dosage, type and time of hypoglycemic drugs.

Nighttime blood sugar monitoring helps detect nocturnal hypoglycemia and morning fasting hyperglycemia. If your blood sugar is too high or too low before going to bed or around 3 a.m., high blood sugar will occur the next morning, but the methods of dealing with it are completely different. Therefore, if patients have obvious discomfort during sleep, they should increase blood sugar monitoring before going to bed or around 3 a.m. to provide reference for doctors so that treatment can be more reasonable.

It is very important to understand insulin levels and blood sugar monitoring at different times. Fasting blood sugar in the early morning or before breakfast reflects the level of insulin secretion in the human body at the basic state. If the blood sugar exceeds normal (>6 mmol/L), it indicates that the basic amount of insulin is insufficient or the patient is insensitive to the effects of insulin. Postprandial blood sugar reflects the level of additional insulin secretion after increased sugar absorption. Patients who are taking medication or controlling their diet need to pay special attention to their blood sugar levels after meals. The blood sugar level 2 hours after a meal is one of the most important indicators for monitoring blood sugar. For normal people, the blood sugar level is <8 mmol/L. The higher the blood sugar level 2 hours after a meal, the greater the chance of cardiovascular and cerebrovascular complications.
