Gas

Fermentation by gut bacteria produces gas.

Gas, also known as flatulence or bloating, refers to the presence of excess air or gases in the digestive system. This can result from various factors, including the breakdown of undigested food by bacteria in the colon, swallowing air while eating or drinking, or certain medical conditions. Symptoms may include abdominal discomfort, bloating, burping, and the passage of gas. While usually a temporary and harmless condition, excessive gas can be uncomfortable and potentially embarrassing. Certain foods are known to contribute to gas production, such as beans, broccoli, cabbage, onions, and carbonated drinks. Underlying gastrointestinal disorders such as irritable bowel syndrome (IBS) or small intestinal bacterial overgrowth (SIBO) can also exacerbate gas production.
