A bad heart may cause bloating, for example, gastrointestinal stasis in right heart failure or total heart failure from various causes can present with a range of gastrointestinal symptoms, including bloating.
In right heart failure, venous return to the body is blocked and a large amount of blood is stagnated in the venous system, which can result in lower limb edema, liver enlargement and other venous stasis.
Prolonged hepatic stasis in turn prevents portal blood from entering the liver, which in turn causes gastrointestinal stasis and mucosal edema, leading to poor digestion and absorption and causing bloating, diarrhea, loss of appetite, dyspepsia, and other gastrointestinal symptoms.
In addition to cardiac causes, most of the bloating is caused by digestive diseases, such as intestinal obstruction, inflammatory bowel disease, irritable bowel syndrome and so on. It is recommended that patients go to the hospital as soon as possible to identify the cause and treat it accordingly.
