Why Do I Feel Nausea After Eating?

Why Do I Feel Nausea After Eating?


Have you ever had nausea after eating? The feeling of nausea produced after eating does not have to be associated with gastrointestinal problems but can also be due to any other neurological or hormonal pathology, among others.

If you have been suffering from nausea after meals, it is important to know the causes in order to try to eliminate them. In this article from Welthy Magazine, we are going to tell you why nausea occurs after eating, analyzing the most determining factors. In any case, it is always advisable to visit the doctor and perform a physical examination to rule out common diseases and consider all possibilities.



If you feel unwell after a meal and feel nauseated or feel like vomiting, two of the most common causes refer to a possible stomach virus or gastroenteritis, or food poisoning.

Food poisoning

Food poisoning is quite common after eating food that is spoiled and contaminated with bacteria or germs. In this situation, people may experience different symptoms, such as nausea and vomiting, stomach cramps, high fever, or diarrhea.

The symptoms are unpleasant, but usually disappear after a few hours or some days without the need for any treatment. Despite everything, it is advisable to visit the doctor to rule out serious food poisoning, something that happens quite rarely.

Stomach flu

Gastroenteritis is another cause of nausea after eating. It is an intestinal type of infection, associated with a stomach virus. It can appear when eating contaminated food and causes the stomach and intestines to become inflamed.

In addition to causing nausea, the most common symptoms of gastroenteritis are stomach pain, diarrhea, vomiting, nausea, or loss of appetite. It is usually quite uncomfortable, as we explained in the previous case, although it usually disappears in a matter of days.

Other causes of nausea after eating

If the nausea has not been caused by gastroenteritis or food poisoning, there may be other reasons that explain its appearance. From here we have prepared a list with the symptoms associated with different common pathologies:

  •   Heartburn or acid reflux. It originates when stomach acid rises into the esophagus and reaches the mouth, causing nausea and the feeling of vomiting.
  •   Flu. Typical flu symptoms, such as headache and high fever, can also be accompanied by nausea.
  •   Inner ear infection or labyrinthitis. This situation can affect the balance of the person and cause dizziness.
  •   Migraines. Increased sensitivity to sound and light can lead to associated headaches and nausea.


Although nausea is not usually a symptom of a serious illness, if it is accompanied by frequent vomiting, sometimes it can be a symptom of a bigger problem. If you feel unwell and are concerned about the severity of your vomiting, it is best to seek medical help. It is also a good idea to consult your GP if the nausea is recurring and it does not go away after a few days.



Nausea that occurs after eating is quite annoying and we often wonder what are the things that can make us feel like vomiting. The first thing we usually do is find a place outdoors to breathe fresh air. This will make breathing easier and help us feel better.

However, if it does not work, it is also possible to resort to other alternative methods such as the ones that we are going to discuss below:

  •   Drink a small amount of liquid, such as water, pennyroyal, ginger tea, chamomile, rice water, red raspberry leaf tea, or licorice root tea. Any of these drinks can be used to eliminate nausea and vomiting. Ginger is the natural substance most likely to end nausea.
  •   Drink sweet liquids. This is a way to provide sugar and mineral salts to your body. This is the case of some isotonic drinks that can help reduce the urge to vomit, such as Aquarius. What you must do is drink in small sips, until you gradually feel better.
  •   Eat something salty that is not oily or fatty. Eat crackers very slowly and in small amounts to settle your stomach. This method can be used not only after eating, but it is also convenient to end nausea caused by the movement of the car or in the case of morning sickness in pregnant women.
  •   Another way to try to get rid of nausea after eating is to breathe slowly and deeply.
  •   If you are surrounded by strong odors, such as tobacco or perfumes, try to get away from them to help stop that uncomfortable feeling.
  •   If you want to avoid nausea caused by food, avoid fried, fatty foods and acidic drinks, such as orange.
  •   Another good solution is to eat more times a day but in less quantity. Also aim for your diet to be rich in fiber to avoid constipation.
  •   It is also convenient to do some exercise. If you feel nauseous after eating, go for a walk in the fresh air and it may go away after a few minutes.
  •   It is important to eat relaxed and seated to facilitate digestion. In the following article we explain what conscious eating consists of and how it can help you.
  •   If after eating you want to rest, you can relax on the sofa or in bed, wherever it is most comfortable for you. Of course, try to be stretched out and not lying down. If you have an upset stomach and want to vomit, it is preferable that you have your head above the height of your feet, unless the dizziness is in the head.
  •   Another effective solution is to wet some areas of the body with cold water. Simply dip a cloth in cool water and place it on specific parts of the body that can alleviate these symptoms of discomfort, such as the neck, face, wrists, neck, behind the knees or on the inside area of the elbows.
  •   Another thing you can try is to take any cold thing from the fridge, such as a soft drink, or even bags of food from the freezer, and use them in the mentioned areas. By cooling them, the body temperature will drop and the feeling of dizziness and the desire to vomit will pass.


If after putting these methods into practice, the nausea continues and you keep feeling like vomiting, it is best not to avoid it. In these cases, the body is sending the signal that it needs to relieve an upset stomach and it is best to listen to it and not hold back. By doing so you will feel much better.



Nausea and vomiting often go hand in hand. Previously, we have talked about the most common causes that can cause these symptoms. However, there are other situations that can also generate them, such as indigestion, pregnancy or even chemo treatment.

It can also happen that our balance regulatory system is altered by any circumstance, such as a car or boat trip, causing frequent dizziness.

Also, nausea can appear due to less frequent disorders that may be difficult to diagnose if not with the help of your doctor. As we have already mentioned, if nausea and vomiting persist over time, it is always advisable to consult a specialist to try to find the best solution.

Digestive disease

A liver disease, a gastric ulcer or any other inflammatory disorder can cause nausea and vomiting. Appendicitis, pancreatitis or kidney or biliary colic can trigger vomiting, as in the case of an obstruction of the colon or pylorus.

Sometimes they can be caused by a gastroduodenal ulcer, while in other cases it can be the consequence of a tumor. In any case, in the latter case we will also notice some other changes: consistency and regularity when going to the bathroom, and the presence of blood in the stool.

Anxiety or emotional circumstances

Anxiety disorders can also cause nausea and vomiting. Likewise, they can appear before any stimulus that the brain perceives as unpleasant, such as seeing blood flow from a wound.

Other disorders that cause nausea after meals

Sinusitis or otitis can also cause nausea, although it is not a very frequent thing. In otitis, localized pain and inflammation occurs, while in sinusitis, discharge and headache can lead to uncomfortable nausea.

Tumor-type diseases, strokes and acute myocardial infarctions. These diseases can lead to a picture of nausea and vomiting. In these cases, in addition to nausea and vomiting, other symptoms appear that are easy to detect:

  •   In the case of heart attacks: tingling in the arm, cold sweating and chest pain.
  •   In the case of tumors: tiredness, weight loss and general malaise.
  •   In the case of a stroke: disorientation and difficulty expressing yourself normally.


If you have had no choice but to rest for a long time in a bed as a result of a fracture, an operation or simply due to the impossibility of moving, it is possible that when you start your usual chores again, you will feel nauseated.

We are talking about the syndrome of the superior mesenteric artery, very important in the digestive system, which tends to compress the duodenum in these circumstances. It is something that also happens if the person loses a lot of weight in a matter of a short time.
