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.
Heartburn and poor glycemic control may be the only symptoms of delayed gastric emptying in diabetic patients. Physical examination in patients with gastroparesis may be completely normal or, in its more severe forms, dehydration and malnutrition, as well as a succussion splash, can be present. [12]
Symptoms include tenesmus (the sensation of incomplete emptying of the rectum after defecation has occurred) and constipation. Retention of stool may result in fecal loading (retention of a mass of stool of any consistency) or fecal impaction (retention of a mass of hard stool).
The water and stool may take some time to fully evacuate, especially with patients with obstructed defecation. People with reduced muscular strength of the anal sphincter may encounter problems with later leakage of the water mixed with stool, which may bring similar, socially devastating problems as seen with fecal incontinence.
“Sedentary people have more trouble having their bowels empty,” she explains. “Remember, the longer that you sit down the higher the chances are to develop symptomatic hemorrhoids and ...
Bowel dysfunction caused by a spinal cord injury will vary greatly depending on the severity and level of the spinal cord lesion. In complete spinal cord injury both sensory and motor functions are completely lost below the level of the lesion so there is a loss of voluntary control and loss of sensation of the need to defecate.

This causes symptoms due to the shift of fluid into the intestinal lumen, with plasma volume contraction and acute intestinal distention. [3] Osmotic diarrhea, distension of the small bowel leading to crampy abdominal pain, and reduced blood volume can result. Late dumping syndrome occurs 2 to 3 hours after a meal.
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.
