Gas that passes through the body is a combination of nitrogen, oxygen, hydrogen, methane and carbon dioxide. Dietary causes are typically the cause of severe gas and bloating that is temporary. If gas and bloating are chronic, see your doctor for a diagnosis, as an intestinal disease may be the cause.
Dietary Causes
High-fiber foods are a common cause of gas and bloating. Vegetables, whole grains and beans are healthy selections that can contribute to the formation of gas. Carbonated beverages, such as beer and soda can also be the culprits. In addition, some individuals are intolerant to additives found in sugar-free candies and gums, such as mannitol and sorbitol. Eating too many of these foods can lead to diarrhea, severe gas and bloating.
Constipation
Bowel patterns differ from person to person. However, the experts at FamilyDoctor.org report that a normal range is between three times daily to three times weekly. Individuals who suffer with constipation experience difficulty passing stool, have infrequent bowel movements, or often feel the urge to go even after passing stool. Not drinking enough fluids, getting enough exercise, eating enough fiber, resisting the urge to go, or using laxatives excessively are reasons for constipation. Severe gas and bloating can result from constipation. Check with your doctor before treating constipation, as fiber supplements containing psyllium can worsen gas and bloating for some individuals.
Irritable Bowel Syndrome
Irritable bowel syndrome, IBS, is a common intestinal condition causing constipation, diarrhea, cramping, gas and bloating. Most people are able to treat the condition with diet modifications and lifestyle changes. However, the experts at MayoClinic.com note that a small number of individuals with IBS have severe symptoms. In contrast to other intestinal ailments, such as Crohn's disease and ulcerative colitis, IBS is generally not debilitating, and does not lead to life-threatening complications.
