Water loss of 5fi)-l0ffiml/hour in cholera is know as-
**Core Concept**
Cholera is a diarrheal disease caused by Vibrio cholerae, leading to a massive loss of fluids and electrolytes. The pathogen secretes cholera toxin, which activates the adenylate cyclase enzyme, resulting in an increase in cyclic AMP (cAMP) levels within intestinal epithelial cells. This increase in cAMP leads to a massive secretion of chloride and bicarbonate ions into the intestinal lumen, resulting in a significant loss of fluids.
**Why the Correct Answer is Right**
The correct answer refers to the rate of fluid loss in cholera patients, which is typically estimated to be around 10 liters per hour. This extreme fluid loss is due to the cholera toxin's ability to increase the secretion of chloride and bicarbonate ions into the intestinal lumen. The increased fluid loss can lead to severe dehydration, electrolyte imbalances, and even death if left untreated.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a recognized term for fluid loss in cholera patients.
**Option B:** This option is not a correct estimate of fluid loss in cholera patients.
**Option C:** This option is not a recognized term for fluid loss in cholera patients.
**Clinical Pearl / High-Yield Fact**
It's essential to recognize the rapid progression of dehydration in cholera patients and provide prompt treatment with intravenous fluids and antibiotics to prevent complications. A key clinical correlation is that cholera patients often present with a characteristic "rice-water" stool, which is a result of the massive loss of chloride and bicarbonate ions.
**Correct Answer:** C. 10 liters per hour.
