Patients with rectal obstruction (e.g., from fecal impaction, obstruction due to a vaginal pessary) may also present with pseudodiarrhea, since only liquid stool can make it through. [2] [3] Pseudodiarrhea may be more common than chronic diarrhea and should always be considered in patients complaining of chronic diarrhea. [citation needed]
Volvulus can also arise as a rare complication in persons with redundant colon, a normal anatomic variation resulting in extra colonic loops. [ 12 ] Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract.
The faeces being in the colon for a longer time will mean that more water is absorbed leading to harder stools and therefore increasing the symptoms of constipation. This neurological problem can also lead to reduced sensation of rectal filling and weakness of the anal sphincter because of weak muscular contraction so can cause stool leakage ...
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. [2] However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
Hypothyroidism can also cause chronic constipation because of sluggish, slower, or weaker colon contractions. Iron supplements or increased blood calcium levels are also potential causes. Spinal cord injury is a common cause of constipation, due to ileus. [citation needed]
One of the symptoms of diverticulitis, in addition to abdominal pain, constipation, diarrhea, and rectal bleeding, is mucus in the stool. (Check out the foods might help to prevent diverticulitis ...
Chronic intestinal pseudo-obstruction (CIPO) is a very rare syndrome with chronic and recurrent symptoms that suggest intestinal obstruction in the absence of any mechanical blockage of the lumen. [3] The most common symptoms of CIPO include abdominal pain, constipation, nausea, vomiting, dysphagia, and abdominal distention.
Which configuration the rectum ends up in is likely related to several factors: the original position of the rectum, the amount of redundancy of the sigmoid colon (see: dolichosigmoid colon), position of other pelvic organs, laxity of perirectal fascia, and any fixed points resulting from previous surgeries.
