The National Digestive Diseases Information Clearinghouse (NDDIC) notes that the medical community attributes the primary cause of chronic stomach bloating to some form of intestinal disorder. In acute cases, other reasons such as overeating, fibrous foods and lactose intolerance may be the culprit. Several possible causes exist for stomach bloating, and range from minor passing precipitants to chronic and serious conditions. In the case of severe stomach bloating, consultation with a physician may offer solutions and preventative care.
Gas From Food
Food broken down in the digestive process becomes eliminated waste. However, some of the waste products become gas comprised of methane, oxygen and nitrogen that eventually passes through the intestines and gets excreted. When gas does not pass as part of normal digestion, pressure in the abdominal area results. Certain foods or intolerance of foods initiate this process, according to the Women Fitness website. Foods containing carbohydrates are more likely to cause gas than foods high in fat and protein. The NDDIC lists sugars such as lactose, fructose and sorbitol as gas inducers. Fruits and vegetables, dairy and beans contain these forms of sugar. Starches such as pasta and potatoes as well as fibers found in bran and fruits also cause gas. Problem gas causes stomach bloating and pain, but this typically subsides with time. Simple diet changes and awareness of gas-inducing foods may aid in preventing stomach bloating.
Irritable Bowel Syndrome
Irritable bowel syndrome or IBS is a disorder of the large intestine. Stomach bloating and pain are symptoms commonly associated with this disorder. The Mayo Clinic notes that IBS may result from food being forced quickly through the intestines or passing too slow causing stool to harden and dry. In either event, it results in bloating, pain and gas. IBS is a chronic condition accompanied by mild to moderate symptoms depending on diet, stress level and the presence of other medical conditions.
Intestinal Obstruction
Partial or complete blockage of the bowels resulting in the failure of waste to pass through the intestines characterizes intestinal obstruction. The U.S. National Library of Medicine indicates that bowel obstruction occurs due to blockage in the intestines or another condition such as hernias, preventing bowels from passing correctly. Intestinal obstruction causes abdominal bloating, gas and pain. This is a serious condition requiring medical intervention to treat the obstruction source.
