Intestinal gas is always present throughout the length of the digestive tract, from the stomach to the rectum and is a result of the digestive process. We only notice intestinal gas when it is excessive or causing pain and discomfort.
Excess intestinal gas in the stomach or upper intestine can result in excess burping or belching. Excess intestinal gas in your colon or lower intestine results in increased gas being passed. (flatulence). Excess gas from any location in the gastrointestinal tract can cause cramping or pain. This typically will not be associated with any specific or obvious pattern.
Most people burp occasionally and people pass gas rectally several times a day as a normal part of daily activities and food breakdown. Sometimes, excessive intestinal gas can indicate a digestive disorder.
By itself, intestinal gas is rarely a sign or symptom of a serious condition. It can cause discomfort and embarrassment, but it's usually just a sign of a normally functioning digestive system. If you're bothered by intestinal gas, try changing your diet.
However, see your doctor if your gas is persistent or severe, or if it's associated with vomiting, diarrhea, constipation, unintentional weight loss, blood in the stool or heartburn
