Decreasing intestinal motility prolongs the transit time of food content through the digestive tract, which allows for more fluid absorption; thereby alleviating diarrhea symptoms and improving stool consistency and frequency. [4] Unlike other opiates, loperamide does not cross the blood brain barrier, so there is minimal risk for abuse. [5]
Secretory diarrhea means that there is an increase in the active secretion, or there is an inhibition of absorption. There is little to no structural damage. The most common cause of this type of diarrhea is a cholera toxin that stimulates the secretion of anions, especially chloride ions (Cl –).
Bile acid malabsorption (BAM), known also as bile acid diarrhea, is a cause of several gut-related problems, the main one being chronic diarrhea.It has also been called bile acid-induced diarrhea, cholerheic or choleretic enteropathy, bile salt diarrhea or bile salt malabsorption.
Cholera toxin B pentamer, Vibrio cholerae. The complete toxin is a hexamer made up of a single copy of the A subunit (part A, enzymatic, ), and five copies of the B subunit (part B, receptor binding, ), denoted as AB 5.
Stool osmotic gap is a measurement of the difference in solute types between serum and feces, used to distinguish among different causes of diarrhea. Feces is normally in osmotic equilibrium with blood serum, which the human body maintains between 290–300 mOsm/kg. [1] However, the solutes contributing to this total differ.
Diarrhea happens when the amount of fluids absorbed in the intestine does not match the amount secreted. The imbalance can be achieved in two ways: an excess of secretion or a lack of absorption. Thus, diarrhea can be categorized into secretory diarrhea, an excess of secretion, or osmotic diarrhea which is a lack of absorption.
First, the excessive bacterial concentrations can cause direct inflammation of the small bowel cells, leading to an inflammatory diarrhea. The malabsorption of lipids, proteins and carbohydrates may cause poorly digestible products to enter into the colon. This can cause an osmotic diarrhea or stimulate the colonic cells to cause a secretory ...
Enterotoxigenic Escherichia coli (ETEC) is a type of Escherichia coli and one of the leading bacterial causes of diarrhea in the developing world, [1] as well as the most common cause of travelers' diarrhea. [2] Insufficient data exists, but conservative estimates suggest that each year, about 157,000 deaths occur, mostly in children, from ETEC.
