Postmortem bloating occurs in cadavers, due to the formation of gases by bacterial action and putrefaction of the internal tissues of the abdomen and the inside of the intestines. Related conditions
Conditions that are related to bloating include constipation, lactose intolerance, and acid reflux disease. All of these conditions share the same symptoms and can share the same causative agents. These causes include unhealthy diet, smoking, alcohol consumption, low amount of exercise, and overall health. Each of these conditions can be experienced as a symptom of the others and is also a cause for each of them. In most cases where one of the conditions is present, there is at least one if not two of the others. Treatment for each condition is performed using the same medications and recommended dietary changes like increased fiber intake and reduced fat intake. If the conditions develop into diseases such as gastroesophageal reflux disease or chronic constipation, additional medications will be required. Bloating and flatulence are sometimes related to constipation, and treating the underlying condition may be helpful. Treatment
Diets
Promising evidence on the potential efficacy of the low-FODMAP diet in functional abdominal bloating is provided by the reduction of the bloating which has been observed in some studies on patients with irritable bowel syndrome. Regarding the gluten-free diet, there is insufficient scientific evidence to recommend it to reduce bloating and abdominal distension. As regards the FODMAP diet, this should be provided by experts in nutrition to reduce the risks associated with elimination diets.
Soluble fiber is prebiotic and readily fermented in the colon into gases, while insoluble fiber is metabolically inert and absorbs water as it moves through the digestive system, aiding in defecation. Most types of fiber (insoluble) are attached to body water in the intestine and increase the volume of stools. Bowel gas
Gas in the gastrointestinal tract has only two sources. It is either swallowed air or is produced by bacteria that normally inhabit the intestines, primarily the colon.Belching or burping is a universal ability that works by removing gas from the stomach through the mouth. The stomach can become bloated when too much air is swallowed during eating and drinking too quickly. As the stomach swells, belching removes the gas and alleviates the pain associated with it. Burping can also be used as a form of relief from abdominal discomfort other than too much gas in the stomach.Flatulence, or farting, provides relief of much the same kind as burping, but involves the passage of gas from the body via the anus, not the mouth. Bacteria present in the intestinal tract cause gas that is expelled from the anus. They produce the gas as food is digested and moved from the small intestine. This gas builds up and causes swelling or bloating in the abdominal area before it is released. Constipation
A common gastrointestinal problem is constipation—infrequent bowel movements, hard stools, or strain during the movements—which causes serious cases of bloating.
