Causes of fasting blood glucose rebound increase are Sumuje phenomenon, dawn phenomenon, and insufficient dose of hypoglycemic drugs. Generally, there is no need to take medication for Sumuji phenomenon; dawn phenomenon and insufficient dosage of hypoglycemic drugs can be considered to take hypoglycemic drugs.
1. Sumuje phenomenon: generally, hypoglycemia occurs at night, and blood glucose rebounds in the morning due to the body’s protective mechanism, in which case it is necessary to appropriately reduce the dose of hypoglycemic drugs in the evening.
2. Dawn phenomenon: it means that the human body secretes more hormones at dawn, which leads to an increase in blood glucose, and patients can use hypoglycemic drugs to control blood glucose.
3. Insufficient dosage of hypoglycemic drugs: If the dosage of hypoglycemic drugs at dinner is insufficient, it may also cause high fasting blood glucose in the morning, and the dosage of hypoglycemic drugs at dinner can be increased.
Common monitoring indicators of blood glucose include fasting blood glucose, 2-hour postprandial blood glucose, random blood glucose, etc. You can comprehensively determine whether your blood glucose is up to the standard through the above indicators, and you can take medication under the guidance of your doctor if necessary.
In case of rebound of fasting blood glucose, it is recommended to go to the hospital for further treatment under the guidance of specialists.
