It is still unclear how irritable bowel syndrome develops. Scientists suspect that disturbed intestinal motility and hypersensitivity of the gastrointestinal tract in the disease irritable bowel syndrome. Due to the sluggish muscles and their lack of coordination, both porridge and intestinal gases are delayed and then accelerated again, which can cause symptoms such as pressure and bloating, bloating and constipation alternating with diarrhea. Which in turn are causes of these symptoms is unclear.
Irritable bowel: causes unclear
Discussed are changes in the intestinal immune system and nerve transmission as a result of an intestinal infection. Possibly resulting inflammation leads to an imbalance of the intestinal flora (dysbiosis). In addition, nerve stimuli from the gastrointestinal tract seem to be transmitted incorrectly or processed in the brain.
Striking is an increased pain sensitivity of those affected in the intestine: normal nerve stimuli such as stretching the intestine are already interpreted as pain - which explains why especially after eating spasmodic abdominal pain or uncomfortable feeling of fullness occur. Presumably there are other causes or may aggravate irritable bowel symptoms.
Other possible causes of irritable bowel
Other possible causes of an irritable bowel include intolerances of certain foods (especially carbohydrates, especially lactose) and allergies, often the consumption of coffee, alcohol or cigarettes. Stress factors and other psychological stresses that "hit the stomach", the constant feeling of overworking and the inability to express feelings, seem to favor the development of irritable bowel syndrome as well.
Conversely, a long-standing irritable bowel syndrome can again cause mental discomfort. For anxiety disorders or depression, the irritable bowel syndrome is common. Often an excessive colonization with intestinal fungi (Candida) is held responsible - the connection could not yet be scientifically proven.
