It is common to experience abdominal bloating. Bloating is a problem that many people experience repeatedly. The presence of predictable bloating is not normally a cause for concern and stems from a variety of different occurrences. It is common for bloating to be caused by a buildup of gas in the stomach or intestines. It may feel mildly uncomfortable to intensely painful when you have bloating caused by gas. It has been reported that some people feel as if there is something trapped inside their stomachs. Indigestive discomfort or pain, sometimes called dyspepsia, is characterized by bloating in the stomach. Indigestion is common among most people from time to time. An infection in the stomach can lead to bloating. Among these are bacteria such as Escherichia coli and Helicobacter pylori, as well as viruses like norovirus and rotavirus. After a few days, stomach infections usually disappear on their own. It is possible, however, for some people to become severely dehydrated or to continue to deteriorate over a period of time. Bloating can be caused by a monthly period or menopause, among other gynecological problems. Bloating, cramping, and stomach pain can also occur as a result of endometriosis, which occurs when the womb lining attaches to the stomach or intestines.
