Chronic Diarrhea
Chronic Diarrhea |
Diarrhea continuing from weeks, near, or
above two months is called chronic diarrhea. There are five types of this
diarrhea.
1.
Osmotic Diarrhea
This
type of diarrhea is caused by ingestion of an osmotic active substance that puts
a force. Which draws fluid into the intestinal lumen. The increased volume
exceeds the colon’s capacity for reabsorption in diarrhea.
Signs and symptoms: smell in stool, deficiency of nutrition, weight loss, and
osmotic gaps.
Causes: The
common causes are episodes of gastroenteritis, Laxative abuse, pancreatic
insufficiency, Whipple, s disease, and overgrowth of bacteria.
2.
Secretory diarrhea
The
active intestinal secretion of fluid and electrolytes has decreased, the
absorption resulting in diarrhea. It may be large in volume with a normal
somatic gap. The volume of fluid and electrolytes may be decreased to 1-10 L/d.
3.
Inflammatory diarrhea
Inflammatory
diarrhea develops due to damage to the mucosal cells so that there is impaired intestinal absorption and excessive secretion of fluid resulting in
diarrhea. That may contain blood. The patient presents with fever, abdominal
tenderness, and blood in the stool.
4.
Abnormal motility diarrhea
In
this type of diarrhea volume and weight of stool are not increased but defection
occurs due to stasis of intestinal contents and bacterial overgrowth. It results
in malabsorption and diarrhea.
5.
Diarrhea due to chronic infection
The
common causes of this type of diarrhea are infection, inflammatory bowel
disease, an endocrine disorder, malabsorption, irritable bowel syndrome, and
laxative abuse. The more causes are Giardia lambia, entameba histolytica, and
abdominal TB.
