Yes, allergies can definitely cause stomach problems. While allergies are often associated with sneezing, itchy eyes, and a runny nose, they can also significantly impact the gastrointestinal (GI) tract. This is because allergic reactions aren't limited to the respiratory system; they can affect the entire body, including the gut.
How Allergies Affect the Stomach
Several mechanisms explain the link between allergies and stomach problems:
-
Histamine Release: When your body encounters an allergen (like a food or pollen), it releases histamine. This histamine, in addition to causing typical allergy symptoms, can also affect the gastrointestinal tract. It can lead to increased gut motility (movement), altered secretions, and inflammation, resulting in symptoms like stomach cramps, bloating, diarrhea, and nausea.

-
Direct GI Tract Impact: Allergens can directly irritate the lining of the gut, causing inflammation and resulting in digestive issues. Even tiny amounts of an allergy-causing food can trigger symptoms like digestive problems. [Source: Food allergy - Symptoms and causes - Mayo Clinic]
-
Specific Allergy Types: Food allergies are a common cause of stomach problems. Symptoms can range from mild discomfort to severe reactions. For example, a soy allergy can cause stomach problems, cough, and even anaphylaxis. [Source: Soy Allergy: Causes, Symptoms, Tests & Treatment]
