Quick Answer: Why Do I Feel Nauseous When I Eat Whole Wheat Bread?

Wheat Bread & An Upset Stomach

If you’re treating an upset stomach with wheat bread, stick to white bread; whole-wheat bread may contain too much fiber, prolonging or exacerbating your symptoms. The most effective way to treat an upset stomach is to change your diet until your symptoms improve.

Treating an Upset Stomach

White wheat bread is a bland, easy-to-digest food that will help you form firm stools and maintain regularity. If your upset stomach is causing excessive vomiting and diarrhea, you may need to stop eating for a few hours. Talk to your doctor about any diet changes.

Wheat Allergy

Wheat contains five proteins that can cause an immune system overreaction, which causes chemical production throughout your body, resulting in common wheat allergy symptoms such as stomach pain, nausea, vomiting, diarrhea, and cramping, as well as symptoms in your sinuses, lungs, and skin.

Wheat Intolerance

Gluten is one of the proteins in wheat that can trigger an immune system reaction in the small intestines, causing permanent damage to your digestive system and possibly malnutrition.


Wheat allergies and intolerances have no cure and must be managed through avoidance. Consult your doctor or a dietitian to develop a wheat and gluten-free diet. Wheat and gluten can be found in a variety of foods, including bread, cereals, candy, and pasta.
