What Are Gas and Bloating?
Gas
Gas forms naturally in the digestive tract during digestion and from swallowed air.
Common causes of gas include:
- Eating too quickly
- Carbonated drinks
- Certain foods
- Swallowing air while talking or chewing gum
- Digestive fermentation by gut bacteria
Passing gas is a normal bodily function.
Bloating
Bloating refers to a feeling of fullness, pressure, or swelling in the abdomen.
Some people may also notice:
- Tightness in the stomach
- Visible abdominal swelling
- Discomfort after meals
- Excessive burping or flatulence
Occasional bloating is common, especially after large meals.
