Hypoglycemia is relatively common among diabetic patients or those in the prediabetic stage. This occurs partly due to impaired blood sugar regulation and partly due to improper use of hypoglycemic medications. Beyond diabetes, numerous other causes can lead to hypoglycemia, which can be broadly categorized into three types: disease-related, medication-related, and functional.
Analysis of Hypoglycemia Causes
Disease: Tumors in pancreatic islet cells can produce excessive insulin, leading to recurrent hypoglycemia. Blood tests reveal abnormally elevated insulin levels. Endocrine disorders affecting the adrenal glands, thyroid, or pituitary gland may also cause hypoglycemia. Severe liver disease is another potential cause.
Medications and Alcohol: Beyond insulin and other hypoglycemic agents, medications like propranolol and aspirin may also induce hypoglycemia. Additionally, alcohol-induced hypoglycemia warrants attention. Some individuals experience hypoglycemia after drinking alcohol, particularly on an empty stomach.This type of hypoglycemia typically occurs 3-4 hours after meals, with symptoms worsening as meal size increases. Current understanding suggests that ingested food stimulates intestinal polypeptide hormones, which in turn trigger excessive insulin secretion. This leads to a significant drop in blood sugar levels. Blood tests conducted before glucose supplementation often reveal markedly elevated insulin levels in affected patients.
Friendly Reminder
To prevent hypoglycemia, diabetes patients must understand its causes, symptoms, and management methods. Beyond this, gaining knowledge about diabetes—including diet and exercise—is crucial for preventing the disease and its complications.

Patients with access to a blood glucose meter should test immediately. If readings are below 3.8 mmol/L (68 mg/dL), rapidly consume carbohydrate-rich foods such as: half a cup of sweet fruit juice, half a cup of sugar water, 1 tablespoon of honey, 3–5 cookies, 3–4 sugar cubes, or 2–3 candies.If symptoms persist after 10–15 minutes, repeat the dose.
If symptoms resolve but the next meal is over an hour away, add a portion of staple food like 1 slice of bread, 1 steamed bun, or 3–5 cookies. For confusion or sudden loss of consciousness, family members should promptly transport the patient to a hospital.
