While the causes of IBS are still unknown, it is believed that the entire gut–brain axis is affected. [30] [31] Recent findings suggest that an allergy triggered peripheral immune mechanism may underlie the symptoms associated with abdominal pain in patients with irritable bowel syndrome. [32] IBS is more prevalent in obese patients. [33]
Bowel ultrasound (US) is a cost-effective, well-tolerated, non-invasive and readily available tool for the management of patients with inflammatory bowel disease (IBD), including UC, in clinical practice. [79] Some studies demonstrated that bowel ultrasound is an accurate tool for assessing disease activity in people with ulcerative colitis.
Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine, with Crohn's disease and ulcerative colitis (UC) being the principal types. [3] Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas UC primarily affects the colon ...
Reported symptoms of NCGS are similar to those of celiac disease, [30] [31] with most patients reporting both gastrointestinal and non-gastrointestinal symptoms. [29] [32] In the "classical" presentation of NCGS, gastrointestinal symptoms are similar to those of irritable bowel syndrome, and are also not distinguishable from those of wheat allergy, but there is a different interval between ...

Causes of constipation may include faecal impaction and bowel obstruction, which may in turn be caused by ileus, intussusception, volvulus. Inflammatory bowel disease is a condition of unknown aetiology, classified as either Crohn's disease or ulcerative colitis , that can affect the intestines and other parts of the gastrointestinal tract.
Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. [2] About 15% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. [2] In a third of cases, the exact cause is unclear. [2]
