Gas (intestinal gas) means different things to different people. Everyone has gas and eliminates it by belching, burping, or farting (flatulence). Bloating or abdominal distension is a subjective feeling that the stomach is larger or fuller than normal. Belching or burping occurs when gas is expelled from the stomach out through the mouth. Flatulence or farting occurs when intestinal gas is passed from the anus.

Causes of belching or burping include drinking too rapidly, anxiety, carbonated drinks, habit, and swallowing air.

Causes of bloating or distension include tumors, ascites, fluid within the gastrointestinal (GI) tract, and obesity.

Causes of gas or flatulence are diseases such as sugary foods and drinks, fruits and vegetables, starches (wheat, oats, corn, and potatoes), lactose intolerance, untreated celiac disease, and SIBO.

Treatment for excessive intestinal gas depends on the cause. If anal itching persists, a doctor examination may be needed to identify an underlying cause.
