Introduction
In general, elevated blood glucose levels may be caused by factors such as a high-sugar, high-fat diet, lack of physical activity, impaired glucose tolerance, type 2 diabetes, or gestational diabetes. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition through general lifestyle adjustments, medication, or other methods under a doctor's guidance. Regular monitoring of blood glucose levels in daily life and keeping records of glucose fluctuations are important to help doctors adjust treatment plans accordingly.
Under normal circumstances, elevated blood glucose levels may be caused by high sugar and high-fat diets, lack of physical activity, impaired glucose tolerance, type 2 diabetes, or gestational diabetes. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through lifestyle adjustments, medication, and other methods. Specific analysis is as follows:
1. High sugar and high-fat diet: Long-term consumption of sugary drinks, desserts, and fried foods leads to sugar accumulation in the body and elevated blood glucose, often accompanied by weight gain. Adjust your diet by reducing intake of high-sugar and high-fat foods, increasing whole grains, vegetables, and lean meats, controlling staple food portions per meal, eating regularly, and avoiding overeating.
2. Lack of exercise: Prolonged sitting and insufficient physical activity slow down metabolism and reduce insulin sensitivity, impairing the body’s ability to utilize glucose effectively, leading to high blood sugar. Engage in at least 150 minutes per week of moderate-intensity exercise such as brisk walking, jogging, or swimming, about 30 minutes per session. Gradually increase exercise intensity and avoid excessive fatigue.
3. Impaired glucose tolerance: Reduced ability of the body to metabolize glucose results in blood sugar levels higher than normal but not yet meeting the criteria for diabetes; this condition is prone to progress into diabetes. In addition to dietary and exercise management, follow medical advice to take medications such as metformin hydrochloride tablets, acarbose tablets, or gliclazide sustained-release tablets to improve insulin sensitivity and control blood glucose levels.
4. Type 2 diabetes: Insufficient insulin secretion or defective insulin action causes persistently elevated blood glucose, accompanied by symptoms such as increased thirst, frequent urination, and weight loss. Strict dietary control and regular exercise are essential, along with prescribed medications such as insulin aspart injection, pioglitazone hydrochloride tablets, or glimepiride tablets for treatment.
5. Gestational diabetes: Hormonal changes during pregnancy affect insulin function, resulting in elevated blood glucose. If necessary, use insulin-based treatments such as insulin injection, protamine zinc insulin injection, or insulin detemir injection, while avoiding oral hypoglycemic agents that may affect the fetus.
Regular blood glucose monitoring is needed in daily life, with records kept of glucose fluctuations to help doctors adjust treatment plans. Maintain a regular sleep schedule, avoid staying up late, reduce mental stress, and use comprehensive lifestyle interventions to help restore blood glucose to normal levels and support overall health.
