Causes of stomach nausea after eating

1. Food allergies

Everyone has allergies to different types of food. Some are allergic to peanuts, eggs, shellfish, shrimp, and others. When you eat foods that trigger allergies, your immune system releases histamine and other chemicals. These chemicals will produce allergy symptoms in the form of itching, swelling of the mouth or lips, and stomach nausea.

2. Food poisoning

Eating food contaminated with bacteria, viruses, and parasites can make you sick. This happens if the food you consume is not handled properly, starting from the process of selecting food ingredients, cooking, and serving.

Symptoms of food poisoning usually appear within hours, days, even weeks after eating food containing germs or microbes, and will generally be characterized by nausea, diarrhea, stomach cramps, pain after eating.

3. Gastric ulcers

If you are always nauseous after eating, this could be due to irritation caused by a stomach ulcer. Other common symptoms of peptic ulcers are stomach nausea and bloating after eating, a burning sensation in the stomach area, and stomach pain (which is then often referred to as ulcer disease).

4. Pregnancy

One of the earliest signs that you are pregnant is a feeling of discomfort and nausea, which often occurs in the second month of your pregnancy. A study on the causes of vomiting and nausea in pregnancy found that changes in hormone levels in pregnant women can be associated with the appearance of feelings of nausea and vomiting after eating. In fact, sometimes the smell or taste of certain foods is enough to make pregnant women feel nauseous.

The good news is that nausea is temporary and doesn't harm you and your baby.
