Drinking too much alcohol
Abuse of alcohol can result in a deficiency of glucose in the blood. Consuming excessive alcohol can alter the function of liver cells, resulting in liver dysfunction. Chronic alcohol abuse renders the liver incapable of secreting glucagon, which stimulates glucose reabsorption into the circulation. A lack of glucagon hormone is what causes transient hypoglycemia when liver cells malfunction. When the glucose level in the circulation falls, the pancreas secretes the hormone glucagon, which signals the liver to break down glycogen into smaller units of two glucose molecules. When the liver is not functioning properly, however, glucose does not travel back into the bloodstream from glycogen stored in the liver.
