Types of Diarrhea

Acute infectious diarrhea is a clinical and pathophysiological classified into non-inflammatory diarrhea and inflammatory diarrhea. Diarrhea caused by bacterial invasion and inflammation in the colon with manifestation sitotoksin dysentery syndrome with diarrhea with mucus and blood. Clinical symptoms that accompany abdominal complaints such as heartburn to pain such as colic, nausea, vomiting, fever, tenesmus, and the symptoms and signs of dehydration. On routine stool examination found macroscopic mucus and / or blood, and polymorphonuclear leukocyte cells were found microscopically.

 In the non-inflammatory diarrhea, diarrhea caused by enterotoxins that cause watery diarrhea with a large volume without mucus and blood. Abdominal complaints are usually minimal or nonexistent, but the symptoms and signs of dehydration occur rapidly, especially in cases that did not get a replacement fluid. On routine stool examination found no leukocytes.

The mechanism of diarrhea, acute and chronic can be divided into groups of osmotic, secretory, exudative and motility disorders. Osmotic diarrhea occurs when there is a material that can not be absorbed by increased osmolarity in the lumen which draws water from the plasma resulting in diarrhea. Examples are carbohydrate malabsorption due to lactase deficiency or due to magnesium salts.

Types of Diarrhea 

Secretory diarrhea in the event of either electrolyte transport disturbances that reduced absorption or increased secretion. This can occur due to toxins released bacteria such as cholera toxin or the influence of bile salts, short chain fatty acids, or non-osmotic laksantif. Several intestinal hormones such as vasoactive intestinal polypeptide gastrin (VIP) may also cause secretory diarrhea. 

Exudative diarrhea, inflammation will cause damage to both the small intestine mucosa and colon. Inflammation and exudation can occur due to bacterial infection or a non gluten-sensitive enteropathy such infections, inflammatory bowel disease (IBD) or due to radiation.
