Reactive hypoglycemia is a condition characterized by low blood sugar (glucose) levels that occur after eating, typically within four hours after a meal. It is also known as postprandial hypoglycemia. This condition is different from fasting hypoglycemia, which occurs when a person has not eaten for an extended period.

Symptoms

Symptoms of reactive hypoglycemia can include:

• Shakiness
• Sweating
• Confusion
• Weakness
• Anxiety
• Difficulty concentrating

These symptoms are the result of the body's response to low blood sugar levels, which can affect the brain and other organs.

Causes

Reactive hypoglycemia is often caused by an excessive insulin response to a meal. When a person consumes carbohydrates, the body breaks them down into glucose, which enters the bloodstream. In response, the pancreas releases insulin to help cells absorb glucose. In some individuals, the pancreas may release too much insulin, causing blood sugar levels to drop too low.

Diagnosis

Diagnosis of reactive hypoglycemia typically involves:

• A detailed medical history
• Blood tests to measure glucose levels
• Observing symptoms in relation to meals

A healthcare provider may conduct a mixed-meal tolerance test to observe how the body responds to a specific meal.

Management

Management of reactive hypoglycemia focuses on dietary changes, such as:

• Eating small, frequent meals throughout the day
• Including protein and fiber in meals to slow glucose absorption
• Avoiding high-sugar foods and drinks

In some cases, a registered dietitian may help create a personalized meal plan.
