Urge incontinence is characterized by a sudden need to defecate, with little time to reach a toilet. Urge and passive FI may be associated with weakness of the external anal sphincter (EAS) and internal anal sphincter (IAS) respectively. Urgency may also be associated with reduced rectal volume, reduced ability of the rectal walls to distend ...
Fecal incontinence or constipation occurs when there is a problem with normal bowel functioning. This could be for a variety of reasons. The normal defecation pathway involves contractions of the colon which helps mix the contents, absorb water and propel the contents along. This results in feces moving along the colon to the rectum.

Getting your body moving can help your bowels do the same. “Regular physical activity, even simply walking, can help to stimulate your bowels to make your stools more regular,” says Moore.
Typically such patients complain of defecation urgency and frequent bowel movements, but only small fecal pellets are passed leaving a sensation of incomplete evacuation. During defecation patients may need to support the perineum on both sides, or evacuate fecal pellets from the rectum with a finger. There may be post defecation incontinence.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Individuals prone to DIOS tend to be at risk for repeated episodes and often require maintenance therapy with pancreatic enzyme replacement, hydration and laxatives (if the symptoms are also mild). [ 4 ] [ 5 ] Oral contrast instillation into the colon/ileum under radiological control has been found to reduce the need for surgical intervention.
Tenesmus is characterized by a sensation of needing to pass stool, accompanied by pain, cramping, and straining. Despite straining, little stool is passed. [3] Tenesmus is generally associated with inflammatory diseases of the bowel, which may be caused by either infectious or noninfectious conditions.
Fecal vomiting occurs when the bowel is obstructed for some reason, and intestinal contents cannot move normally. Peristaltic waves occur in an attempt to decompress the intestine, and the strong contractions of the intestinal muscles push the contents backwards through the pyloric sphincter into the stomach, where they are then vomited.
