What should I do if my fasting blood sugar is high? What is the reason?

Some friends find that they also show high blood sugar when fasting. This situation does happen. It may be caused by problems with the body's hormone regulation or poor living habits. For such unusual situations, you can go to the hospital for examination. If you have any disease, you can receive timely treatment.

1. Impaired hormone regulation

Fasting blood sugar in diabetes is more difficult to control than blood sugar after lunch or dinner. This is because the causes of increased fasting blood sugar are more complicated. After dawn, the normal human body starts to work, start living, and start doing things. In order to ensure that we can carry out normal physiological activities, a lot of hormones are released in the body. These hormones all have the effect of raising blood sugar and are involved in activities that increase blood sugar, such as adrenal cortex hormones, glucocorticoids, and adrenaline, etc., all of which have the effect of raising blood sugar.

These hormones exist under normal physiological conditions. If a person does not have diabetes, then as the glucose-raising hormones increase, the glucose-lowering hormones, such as insulin, will also increase, so that the two can offset each other. When the pancreatic function of diabetic patients is damaged, they become insensitive to insulin. Therefore, in the morning, the glucose-raising hormones still work, but the glucose-lowering hormones stop working, resulting in high blood sugar.

2. The patient's bad living habits

In addition, the increase in blood sugar in patients with type 2 diabetes is also related to meals at night, the quantity and quality of diet, and also to the rest and sleep status at night. If the patient eats more at night, or eats late, or has high calorie intake, it will cause an increase in fasting blood sugar in the morning. If you don't sleep well at night, suffer from insomnia, are in a bad mood and feel very tired, your fasting blood sugar in the morning will fluctuate, sometimes high and sometimes low. This is an uncontrollable factor.

3. Blood sugar is low first and then high

There are also some conditions that are less common but also occur in diabetic patients, such as nocturnal hypoglycemia. This situation occurs when diabetic patients control their diet but use more hypoglycemic drugs. Regardless of whether they are taking insulin or oral hypoglycemic drugs, they may experience hypoglycemia at night and hyperglycemia the next morning. This is the so-called hyperglycemia after hypoglycemia.
