When the body’s glucose level falls below a specific level, a medical condition known as hypoglycemia, also referred to as low blood glucose or low blood sugar, takes place. Low blood sugar levels, or those below 70 mg/dL, make it difficult for the body’s cells and organs that use glucose as a source of energy to function at their best.

Hypoglycemia exists in three stages, mild, moderate, and severe hypoglycemia. Some of the most common types of hypoglycemia are as follows:

• Reactive Hypoglycemia
• Fasting Hypoglycemia
• Drug-Induced Hypoglycemia
• Idiopathic Hypoglycemia
• Hypoglycemia associated with critical illness

There are many possible causes of hypoglycemia. Here are some of the most common:

• Diabetes medications
• Skipping meals or fasting
• Alcohol consumption
• Medical conditions
• Insulin overproduction
• Excessive exercise
• Malnutrition

In some cases, people with hypoglycemia may not experience any symptoms. However, the following are some common symptoms of hypoglycemia:

• Instability

• Rapid heartbeat
• Headache
