Hypoglycemia Symptoms and Treatment

Modified on Apr 21, 2023

What Is Hypoglycemia?

The body’s main energy source is glucose or sugar. As the body breaks down glucose, it releases energy and regulates several of the body’s processes. However, when the blood sugar drops to an abnormally low level a condition called hypoglycemia occurs, causing a range of symptoms and issues. Hypoglycemia is most commonly associated with diabetes; however, several additional health conditions may cause or be linked to the development of hypoglycemia. Much like a fever, hypoglycemia is not actually the disease itself but rather is an indicator of an underlying health problem.

The symptoms of hypoglycemia may vary depending on the individual as well as the exact cause. Nonetheless, several common symptoms can help identify hypoglycemia. Common symptoms of hypoglycemia include confusion, abnormal behavior, heart palpitations, shakiness, anxiety, sweating, hunger and a tingling sensation around the mouth. While uncommon, hypoglycemia may also cause seizures and loss of consciousness.


Maintaining a constant blood sugar level is important for sustained health and energy. As the blood sugar falls below a normal level, hypoglycemia occurs. This drop in glucose level may be caused by a variety of factors. Drug use, diabetic treatment, critical illness, insulin overproduction, endocrine deficiencies and excessive alcohol consumption may all lead to hypoglycemia.
