What causes low blood sugar?

Generally, low blood sugar may be caused by insufficient food intake, improper diabetes management, malnutrition, hepatitis, or adrenal cortical insufficiency. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Insufficient food intake: Dieting for weight loss or excessive exercise may deprive the body of adequate energy supply, leading to decreased blood glucose levels. It is advisable to maintain regular meal times with consistent daily routines to help alleviate symptoms.

2. Improper diabetes treatment: Diabetic patients using hypoglycemic medications—such as insulin aspart injection, insulin degludec injection, or orlistat capsules—may develop hypoglycemia if the dosage is too high or the timing of administration is inappropriate.

3. Malnutrition: Irregular eating habits or prolonged dieting can lead to inadequate nutrient intake, affecting blood glucose levels and causing hypoglycemia, often accompanied by weight loss. Patients are advised to take medications such as Bifico (Bacillus subtilis and Clostridium butyricum) granules, Clostridium butyricum powder, or Ajiao oral liquid as directed by their physician.

4. Hepatitis: The liver plays a key role in glucose production and storage. Long-term alcohol consumption or viral infections may damage the liver and lead to hepatitis, impairing its ability to synthesize and release glucose effectively, thereby causing low blood sugar. Symptoms may also include jaundice and ascites. Patients should follow medical advice when using medications such as azathioprine tablets, bicyclol tablets, or recombinant human interferon α2b injection.

5. Adrenal cortical insufficiency: This condition may result from genetic factors or pathogenic infections, leading to reduced secretion of adrenal cortical hormones. This hormonal deficiency can cause low blood sugar, along with symptoms such as hyperpigmentation and blood pressure fluctuations. Patients may improve with medications such as spironolactone tablets, betamethasone tablets, or prednisolone acetate tablets, taken as prescribed.

In daily life, patients are encouraged to drink plenty of warm water, maintain sufficient sleep, avoid staying up late, and adopt healthy lifestyle habits that support recovery.
