Why Does Pizza Give Me Diarrhea?

If eating pizza results in a hurried trip to the bathroom, it's important to discover the underlying issue causing your diarrhea.

When your body doesn't produce enough lactase — the enzyme that breaks down lactose from dairy products — you could have episodes of diarrhea after consuming the milk-based cheese on your pizza.

• Bloating
• Diarrhea
• Gas
• Nausea
• Pain in your abdomen
• Stomach "growling" or rumbling sounds
• Vomiting

If you're allergic to one or more ingredients in your favorite splurge food, eating it could cause mild to severe symptoms, including diarrhea, withinminutes to several hours. Dairy, wheat and shellfish are a few of the common allergens that can be linked to ingredients found in pizza.

In addition to digestive disorders, signs of an allergy from your pizza may include:
