Why does hypoglycemia occur frequently?

Patient's question:

Palpitations, fatigue, sweating, hunger, pale complexion, tremor, lasting 10-20 minutes

Doctor's answer:

Hello, hypoglycemia may be caused by insufficient food intake, excessive exercise (long duration, sudden), reduced kidney function, leading to decreased clearance of insulin and hypoglycemic drugs, as well as failure of adrenal, thyroid, or pituitary function.
Advice: If timely energy supplementation is not provided, hypoglycemic reactions will naturally occur. To prevent morning or nighttime hypoglycemia, patients can choose slowly digestible foods before bed, such as a cup of yogurt or low-fat milk. Drinking some sugar water to increase calories may help improve the condition.
Lifestyle care: Pay attention to regular meals and a nutritious diet.
