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 ...
Intestinal infectious diseases include a large number of infections of the bowels, including cholera, typhoid fever, paratyphoid fever, other types of salmonella infections, shigellosis, botulism, gastroenteritis, and amoebiasis among others. [1] Typhoid and paratyphoid resulted in 221,000 deaths in 2013 down from 259,000 deaths in 1990. [2]
Diseases of the intestine may cause vomiting, diarrhoea or constipation, and altered stool, such as with blood in stool. Colonoscopy may be used to examine the large intestine, and a person's stool may be sent for culture and microscopy. Infectious disease may be treated with targeted antibiotics, and inflammatory bowel disease with ...
The most common causes of intestinal parasites are through consumption of contaminated water, infected soil, inadequate sanitation and hygiene, and improper hygiene. [3] Specifically, lack of access to facilities for safe disposal of human waste can result in intestinal parasites and disease.
This can cause complications such as: Bowel obstructions may occur due to strictures, particularly in the small intestine, and may require surgical removal of the affected segment (bowel resection) or surgical dilation (stricturoplasty). [2] Fistulas, openings in the gut, result from penetrating disease and can cause diarrhea, urinary tract ...
Diseases like scleroderma [21] cause diffuse slowing of the bowel, leading to increased bacterial concentrations. More commonly, the small bowel may have anatomical problems, such as out-pouchings known as diverticula that can cause bacteria to accumulate. [22]
Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis and intussusception. [1] [2] Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus.
Autoimmune causes of enteritis such as Crohn's disease require significant chronic treatment to avoid nutritional deficiencies, cancer, bacterial overgrowth, and other complications. [5] Some patients with mild forms of the disease may not need treatment, but a majority of people with Crohn's disease require glucocorticoid medications. [24]
