Hypoglycemia occurs if blood glucose levels fall below normal. It is generally defined as blood sugar below 70 mg/dL, although this level may not necessarily cause symptoms in all patients.

Causes of hypoglycemia 

  • Acute hepatic coma
  • Addison’s disease
  • Alcohol intake
  • Cirrhosis
  • Excess exercise
  • Fructose intolerance
  • Gastroenteritis
  • Hypopituitarism
  • Insufficient intake of food
  • Insulinomas
  • Long-term diabetes
  • Partial gastrectomy
  • Respiratory illnesses
  • Retroperitoneal fibrosarcoma
  • Tight blood sugar control

Hypoglycemia unawareness

This is a condition in which people become accustomed to hypoglycemic symptoms. They may no longer notice hypoglycemic signs until they become more severe. In such cases, hypoglycemia appears suddenly, without warning, and can escalate to a severe level. Even a single recent episode of hypoglycemia may make it more difficult to detect the next episode.
