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]
Rectal tenesmus is a feeling of incomplete defecation. [1] It is the sensation of inability or difficulty to empty the bowel at defecation, even if the bowel contents have already been evacuated. Tenesmus indicates the feeling of a residue, and is not always correlated with the actual presence of residual fecal matter in the rectum.
IBS or irritable bowel syndrome is a digestive disorder that impacts the large intestine (colon) and causes uncomfortable symptoms like abdominal pain, bloating, and changes in bowel movements ...
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]
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and the entire area of the jejunum and ileum.

Bleeding before childbirth is that which occurs after 24 weeks of pregnancy. [4] Bleeding may be vaginal or less commonly into the abdominal cavity. Bleeding which occurs before 24 weeks is known as early pregnancy bleeding. Causes of bleeding before and during childbirth include cervicitis, placenta previa, placental abruption and uterine rupture.
One review stated that the most common causes of disruption to the defecation cycle are associated with pregnancy and childbirth, gynaecological descent, or neurogenic disturbances of the brain-bowel axis. [44] The pathophysiologic mechanisms are thought to be different in obstructed defecation compared with slow transit constipation. [43]
Several pathogens can cross the placenta and cause (perinatal) infection. Often microorganisms that produce minor illness in the mother are very dangerous for the developing embryo or fetus. This can result in spontaneous abortion or major developmental disorders. For many infections, the baby is more at risk at particular stages of pregnancy.
