Hypoglycemia (Low Blood Sugar): Symptoms & Signs

Hypoglycemia (low blood sugar) means that blood levels of glucose are too low. This condition is most commonly a complication of treatment for diabetes. Symptoms of hypoglycemia vary among people. When blood sugar levels drop, symptoms can include

• trembling,
• anxiety,
• palpitations (fast or pounding heartbeat),
• sweating,
• clammy skin, and
• hunger.

These are among the early symptoms of hypoglycemia. Other possible symptoms of low blood sugar can be

• dizziness,
• lightheadedness,
• chills,
• nausea, and
• lack of coordination.

If the low blood sugar levels persist, more serious symptoms develop, such as

• headache,
• confusion,
• difficulty with thinking, and
• seizures.

Eventually, coma may develop.

Causes of hypoglycemia

Hypoglycemia occurs as a side effect of many treatments for type 1 or 2 diabetes. There are other rare causes for the condition, such as insulin-producing tumors (insulinomas) and certain medications.
