Insulin or Oral Hypoglycemic Overdose: This is often the most common cause of hypoglycemia, especially in patients with diabetes mellitus who are on insulin or oral hypoglycemic agents. The overdose can lead to an excessive decrease in blood glucose levels.

Diabetic Medication Mismanagement: Incorrect dosing or timing of diabetic medications can lead to hypoglycemia.
Alcohol-Induced Hypoglycemia: Alcohol can cause hypoglycemia by inhibiting gluconeogenesis in the liver.
Fasting or Starvation: Prolonged fasting or starvation can lead to hypoglycemia due to depletion of glucose stores.
Adrenal Insufficiency: Lack of cortisol can impair the body's ability to respond to hypoglycemia, leading to its worsening.
Hypopituitarism: Deficiency in growth hormone or cortisol can contribute to hypoglycemia.

Insulinoma: A rare tumor of the pancreas that produces excess insulin, leading to hypoglycemia. Missing this diagnosis could lead to prolonged, unexplained hypoglycemia and potential neurological damage.
Factitious Hypoglycemia: Self-induced hypoglycemia, often seen in healthcare workers or those with access to insulin, which can be life-threatening if not recognized.
Severe Hepatic Dysfunction: The liver plays a crucial role in glucose metabolism. Severe liver disease can lead to hypoglycemia due to impaired gluconeogenesis and glycogenolysis.

Congenital Hyperinsulinism: A rare condition in infants where the pancreas produces too much insulin, leading to severe hypoglycemia.
Glycogen Storage Diseases: A group of genetic disorders that affect the body's ability to store and release glucose, potentially leading to hypoglycemia.
Glucagon Deficiency: A rare condition where the pancreas does not produce enough glucagon, a hormone that raises blood glucose levels.
Anti-Insulin or Anti-Insulin Receptor Antibodies: Rare autoimmune conditions that can cause hypoglycemia by either binding to insulin or its receptor, mimicking insulin action.
