When to see a doctorBy Mayo Clinic staff
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.
