Gas or flatulence is a common medical condition for which people visit their doctor. Common symptoms of gas are abdominal bloating, abdominal pain, passing a lot of gas (flatulence) and belching. You may not experience all the symptoms and the severity of symptoms may vary from mild to severe. Severity and nature of symptoms depends on how much gas your body produces, the amount of fatty acids the body absorbs and your sensitivity to gas in the large intestine.
Bloating may be caused because of an intestinal disorder, such as irritable bowel syndrome (IBS). The cause of IBS is unknown, but it may involve abnormal movements and contractions of intestinal muscles and increased pain sensitivity in the intestines. These disorders may give a sensation of bloating because of increased sensitivity to gas. Some other conditions that may cause bloating include many operations of abdomen, internal hernias or formation of bands of internal scar tissue called adhesions. Eating a lot of fatty food can also cause bloating as stomach emptying is delayed making one feel uncomfortable. Bloating may be caused as a complication of fundoplication surgery to correct GERD. In this surgery, a one-way valve is created between the oesophagus and stomach to allow food and gas to enter the stomach, but often prevents normal belching and the ability to vomit. In most cases, however, the symptom improves with time.
These are some symptoms of gas or flatulence, though all the symptoms can be caused because of many other conditions of the abdomen. Your doctor can examine you and diagnose the cause of your symptoms and treat it appropriately.
