Why do I feel dizzy after eating?

In this brief guide, we will answer the query, “Why do I feel dizzy after eating?”. We will also talk about the condition that makes you dizzy after eating, its causes, and possible treatment options.

Why do I feel dizzy after eating? 

Feeling dizzy after eating can be due to decreased blood sugar levels or decreased blood pressure levels. Food typically is consumed to energize and boost productivity by supplementing nutrition, minerals, and vitamins that are depleted by daily activities.

But if you are feeling lightheaded and dizzy after eating food then there is a problem and the root causes are, postprandial hypotension or low blood pressure and low blood sugar or hypoglycemia.

Hypoglycemia 

The light-headedness or feeling dizzy after eating a good meal can be caused due to reactive hypoglycemia, a type of hypoglycemia that occurs in a non-diabetic person within four hours of eating a meal.

As you intake the food, the body releases too much insulin which results in the drop in blood sugar levels and the person feels dizzy. Insulin is a hormone that is responsible for maintaining blood sugar levels and lowering glucose levels.

In this condition, the blood sugar level of the person decreases after eating instead of increasing causing the sudden lowering of blood sugar levels.

The symptoms that can occur if you have these conditions are:

  • Nervousness
  • Confusion
  • Hunger
  • Irritability
  • Shaking
  • Sweating
  • Feeling anxious
  • Rapid heartbeat
  • Blurred vision

Reactive hypoglycemia is more common in obese and overweight people.

Postprandial hypotension 

Postprandial hypotension is the lowering of blood pressure after eating food. It happens due to the blood being directed to the digestive system to process the food. The nervous system, circulatory system, and digestive system work really hard and the heart has to pump blood faster to other parts of the body too.

The blood flow is all focused on the stomach and small intestine to help process food which makes the rest of the body not have much blood in the system which makes the head to be light and dizzy.

Other symptoms that occur when having postprandial hypotension include:

  • Chest pain
  • Feeling faint/ tired
  • Nausea
  • Visual changes
  • Vision disturbances
  • Mini strokes

People who already suffer from high blood pressure are more prone to the risk of postprandial hypotension.

Dietary triggers

Feeling dizzy after eating certain types of foods can also happen as some foods can trigger a condition either temporary or chronic that can cause dizziness.

Drinking coffee or other caffeinated drinks can cause dizziness or light-headedness for some people as caffeine is a stimulant and can cause the heart beat faster.

Some people can feel dizzy after eating an excessive amount of spicy foods if they are not accustomed to chillies in their diet. Drinking alcohol can also make you lightheaded since alcohol is a sedative and depressant that affects the central nervous system.

Can these conditions be treated? 

The conditions that cause dizziness when you eat can be treated as the root cause that needs to be tackled first. Reactive hypoglycemia can be treated by making some changes in lifestyle and food choices.

It is advised to eat smaller meals but eat throughout the day instead of big three meals. Fiber and protein-rich foods such as whole grains, lean meat, beans and fruits, and vegetables need to be incorporated into the meals to avoid or reduce the risk of reactive hypoglycemia.

In the case of postprandial hypotension, a few lifestyle changes can improve the symptoms. Eating foods that take a longer time to digest with high fiber and fewer carbs and sugar is recommended. Whole grains, healthy oils, lean meat and beans need to be added to the diet.

How to prevent or reduce dizziness after eating? 

A person can reduce or prevent dizziness after eating by changing certain things in their daily activities. Here we discuss the lifestyle changes that need to be done in order to avoid dizziness.

  • Eating small meals every three hours
  • Avoid eating big meals
  • Drinking enough water between meals
  • Limiting caffeine, alcohol, and sodium intake
  • Adding enough lean protein, high-quality carbs, and healthy fats to the diet
  • Keep track of the blood sugar levels
  • Abstain from refined and processed foods such as white bread, rice, and sugary drinks
  • Exercise regularly and keep track of blood pressure and blood sugar levels
  • Always take your medication for blood pressure and diabetes if you take any
