Why does blood sugar increase after exercise, and what should be done?

Generally, elevated blood sugar after exercise may be caused by factors such as blood circulation, increased secretion of blood glucose-raising hormones, mental stimulation, hyperinsulinemia, or autoimmune diabetes. It is recommended to seek timely medical attention, identify the cause, and follow medical advice for treatment. Details are as follows:

1. Blood Circulation: After exercise, accelerated blood circulation in the body might lead to the breakdown of liver glycogen into glucose, which enters the bloodstream, affecting blood sugar levels and causing an increase. It is recommended to maintain a regular exercise routine and avoid strenuous activity.

2. Secretion of Glucose-raising Hormones: Following acute exercise, the body may secrete increased amounts of glucose-raising hormones, such as glucocorticoids and adrenal cortical hormones. These hormones can stimulate the conversion of liver glycogen into glucose, resulting in a rapid rise in blood sugar levels within a short time. It is advised to avoid consuming high-sugar foods before exercise to minimize blood sugar fluctuations.

3. Mental Stimulation: Excessive mental stress during exercise can elevate cortisol levels in the body, potentially leading to increased blood sugar. It is recommended to reduce psychological stress through activities such as listening to music, watching television, or traveling, and ensure adequate sleep.

4. Hyperinsulinemia: When insulin concentration in the blood exceeds the normal range, the body secretes more insulin to maintain stable blood sugar levels and lower blood glucose. Excessive insulin can affect blood sugar regulation, causing elevated blood sugar after exercise, often accompanied by symptoms of hyperlipidemia. Antidiabetic medications such as Metformin Hydrochloride Tablets, Glimepiride Tablets, or Acarbose Tablets may be used according to medical advice for glucose-lowering treatment.

5. Autoimmune Diabetes: In patients with autoimmune diseases, the immune system mistakenly attacks its own pancreatic beta cells, damaging or destroying their function. This leads to impaired or absent insulin secretion, making it difficult for the body to utilize and store glucose, resulting in persistently elevated blood sugar levels accompanied by symptoms such as polyuria. Antidiabetic medications such as Metformin Hydrochloride Tablets, Glipizide Extended-Release, or Gliclazide Modified-Release Tablets may be taken under medical guidance to help control blood sugar levels and manage the condition.

Monitor blood sugar levels appropriately before, during, and after exercise to understand changes in blood glucose. Additionally, maintaining regular eating habits in daily life is important, avoiding excessive intake of sugary foods or beverages before and after physical activity.
