Cholera patient having stool output 1000-1500 mL/day is known as:
**Core Concept**
Cholera is a diarrheal disease caused by Vibrio cholerae, characterized by massive fluid and electrolyte loss in the stool. The severity of cholera is often classified based on the stool output, with different terms describing varying levels of dehydration.
**Why the Correct Answer is Right**
The term "secretory diarrhea" is not specific to cholera, but in this context, it refers to a condition where the stool output is high, around 1000-1500 mL/day. In cholera, this is due to the toxin secreted by Vibrio cholerae, which stimulates the intestinal epithelial cells to secrete large amounts of chloride and bicarbonate ions into the lumen, resulting in a high-volume watery diarrhea.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not describe a condition with high stool output. Secretory diarrhea can be caused by various factors, but in the context of cholera, it's not the most specific term.
**Option B:** This option is incorrect as it refers to a condition with low stool output. Oligo diarrhea is characterized by a decrease in stool frequency and volume, which is opposite of what is seen in cholera.
**Option C:** This option is incorrect as it refers to a condition with a high stool output, but it's more commonly associated with inflammatory diarrhea, such as in inflammatory bowel disease.
**Clinical Pearl / High-Yield Fact**
In cholera, the stool output is often described using the following scale:
- **Rice-water stool**: 1000-1500 mL/day
- **Cholera gravis**: >1500 mL/day
- **Cholera sicca**: <1000 mL/day
**Correct Answer:** C. Secretory diarrhea
