What Are Some Common Reasons for Low Blood Sugar?

Common reasons for low blood sugar, or hypoglycemia, include taking too much insulin, exercising more than normal when on diabetes medication and eating less than usual, notes Mayo Clinic. Low blood sugar in individuals without diabetes in not common, but sometimes this condition may result from hormone deficiencies, excessive intake of alcohol, and disorders of the liver or the kidney.

Individuals usually associate low blood sugar levels with diabetes treatment, but some health conditions can also cause hypoglycemia in individuals without diabetes, explains Mayo Clinic. Exercising more than usual, eating less than recommended and skipping meals can cause a decrease in blood glucose levels, according to Healthline.

A person without diabetes can experience hypoglycemia by taking diabetes medication or medication used to treat malaria, such as quinine, reports Mayo Clinic. Excessive alcohol consumption without eating can inhibit the release of stored glucose into the bloodstream, resulting in low blood sugar. Conditions that affect the excretory function, liver disease such as severe hepatitis and eating disorders also cause hypoglycemia.

A tumor of the pancreas, called insulinoma, and enlargement of beta cells of the pancreas can result in excessive production of insulin, causing hypoglycemia, explains Mayo Clinic. It is important to have regular checkups for blood sugar to prevent this condition, notes Healthline.
