Definition

Digestive organ in the shape of a pouch located between the esophagus and duodenum. It secretes acids and enzymes to digest food and mix it into a substance called chyme.

How it works

Recommendations

Avoid large meals to not overload the stomach. Wait 2-3 hours after meals for intense activity. Limit alcohol and high-fat foods irritating the stomach.
