Why does an individual feel sick every time he or she eats?

Individuals that feel sick every time that they eat are suffering from some type of intestinal or digestive system distress, as reported by MD-Health. To treat this symptom, consider making dietary changes that better agree with the body; consume foods that help control nausea, like chamomile tea; take anti-nausea medications; avoid certain irritants like cigarette smoke or irritating smells; and relax. If the problem is severe and persists, obtain medical help to determine what the underlying causes may be.

The most common underlying causes of feeling nauseous when eating include:

• Food poisoning. If the food is contaminated by bacteria, virus or fungi, the body will induce vomiting in order to remove these foreign objects.
• Food allergies. Keeping a detailed food journal can help individuals identify which food items they may be sensitive to. An allergy test may offer more conclusive insight.
• Improper eating. This can cause heartburn and other problems to arise, which may lead to feeling nauseous.
• Indigestion. When excessive stress is placed on the body, patients may experience dyspepsia.
• Peptic disease. This happens when the lining of the duodenum, esophagus or stomach is eroded away.
• Acute gastroenteritis. This is more commonly known as the stomach flu.
• Gastroesophageal reflux disease. This happens when undigested food mixes with stomach acid and gets into the esophagus.
