Lactose intolerance refers to the body's inability to digest lactose, a natural sugar found in milk and dairy products. Lactose is broken down by the enzyme lactase. A lack of lactase in the body allows lactose to remain in the digestive system. Here it ferments, allowing gas to build up. The production of lactase can vary, especially in children. The severity of lactose intolerance varies from person to person. Symptoms appear 30 minutes to 3 hours after consumption.
Stress on the abdomen creates bloating. A feeling of tightness or fullness usually accompanies abdominal swelling. Indigestion tends to cause bloating. In the case of lactose intolerance, the digestive malfunction involves the small intestine. As the undigested food passes through the body, bloating will naturally reduce.
