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. It results from excessive movement of sugar into the intestine, which raises the body's blood glucose level and causes the pancreas to increase its release of the hormone ...
The first step in diagnosis is to determine the etiology of abdominal distension. After making a differential diagnosis of abdominal distension, it is important to take a careful medical history. [9] Here are the most common causes of abdominal distension classified as an underlying cause and as a secondary disease. As an underlying disease cause:
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. [2] The stool is often hard and dry. [4] Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. [3]
Ogilvie syndrome, or acute colonic pseudo-obstruction, is the acute dilatation of the colon in the absence of any mechanical obstruction in severely ill patients. [1]Acute colonic pseudo-obstruction is characterized by massive dilatation of the cecum (diameter > 10 cm) and right colon on abdominal X-ray.
Frequent urge to defecate, [12] and frequent bowel movements/toilet visits, [36] where only fecal pellets may be passed. [21] Conversely, there may reduced number of bowel movements per week. [20] [1] Abnormal stool texture, which may be anything from watery/loose (overflow diarrhea), [12] to fragmented, [24] very hard [20] or pellet-shaped. [12]
These are factors that all must be excluded for a diagnosis of functional FI, and are abnormal innervation caused by lesion(s) within the brain (e.g., dementia), spinal cord (at or below T12), or sacral nerve roots, or mixed lesions (e.g., multiple sclerosis), or as part of a generalized peripheral or autonomic neuropathy (e.g., due to diabetes ...
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.
