Overview

Everyone produces intestinal gas through digestion and bacterial fermentation. Excessive gas with bloating occurs when gas production increases (from fermentable foods or bacterial overgrowth) or when the gut becomes hypersensitive to normal gas volumes.

Possible Causes

High-FODMAP Diet

common

Fermentable carbohydrates in wheat, onions, garlic, beans, and some fruits are broken down by gut bacteria, producing excessive gas.

Aerophagia

common

Swallowing excess air from eating quickly, chewing gum, or drinking carbonated beverages.

SIBO

less-common

Bacterial overgrowth in the small intestine causes premature fermentation and excessive gas production.

When It Is Serious

Persistent bloating with weight loss, blood in stool, or symptoms that progressively worsen over months.

When It's Likely Benign

Gas and bloating clearly linked to specific foods that resolve with dietary changes.
