Feeling hungry and nauseous at the same time – Why?

Have you ever noticed that when you go a long time without eating you begin to feel nauseous? Have you ever wondered why this happens when you go long hours without eating? Even when you are hungry you feel nauseous at the same. 

This is usually caused by a build-up of acid in the stomach. Your stomach produces hydrochloric acid as a part of the long process of breaking down food, using what it can for energy and materials, and disposing of the rest.

Why do I feel nauseous when I am hungry?

In order to break down food, your body (stomach) produces hydrochloric acid (HCl). When you go long hours without eating anything, that acid can build up in your stomach and can potentially lead to acid reflux (when the contents from your stomach move back up into your esophagus) and nausea. 

An empty stomach can also cause hunger pangs (painful feelings in your stomach or in the upper left side of the abdomen, usually caused by strong stomach contractions). Hunger pangs are very rarely caused by a health condition. They are mostly attributed to your stomach being empty. 

Hunger pangs can also be affected by the following

  • A need for a diet higher in essential nutrients
  • Hormones
  • Lack of sleep
  • Anxiety or stress
  • Your environment

What can I do about nausea caused by hunger?

Eating is the first thing you can do to get rid of nausea since it is caused by you not eating for a long time in the first place.

According to the British Nutrition Foundation, if you haven’t eaten for a long period of time, gentle ways to address your body’s nutritional needs include:

  • Beverages, such as low-sugar smoothies
  • Brothy soups with protein (lentils, beans) or carbohydrates (rice, pasta)
  • Protein-rich foods, such as fish and lean meat
  • Dried foods, such as dates, apricots, and raisins

Discuss with your doctor or any qualified health personnel if you have intense pain or nausea when you are extremely hungry. It can be a sign that you need to be screened for metabolic syndrome (a group of five risk factors that increase the likelihood of developing heart disease, diabetes, and stroke) and its symptoms such as high blood sugar, increased blood pressure, and abnormal lipid levels.

How to prevent feeling nauseous when you are hungry

Eating at shorter intervals can help you get rid of nausea if you tend to feel nauseous when your stomach has been empty for a long period of time

  • It’s not completely proven if a diet with six small meals a day is healthier than one with three larger meals. But eating smaller amounts of food with less time in between those meals may help prevent nausea.
  • However, Tufts University warns that if you eat a higher number of meals throughout the day, you should be eating less at each sitting compared to what you would eat if you ate fewer meals per day.
  • Tufts University also noted that eating less than three times per day may make it harder to manage your appetite.
  • You can try experimenting with the frequency of meals and the amount consumed at those meals.
  • You can also find a food plan that suits your lifestyle. Make sure that this plan keeps you satisfied, energized, and keeps you at a healthy weight level while avoiding nausea from hunger.
  • A dietician can also help you create a diet and complimentary meal plan based on your needs.
