In acute constipation, purgatives that are common to stimulate intestinal peristalsis and evacuation of fluid feces contain salts of

Options

A. Sodium
B. Magnesium
C. Potassium
D. Calcium

Answer

**Step-by-Step Solution:**

1. **Understanding Constipation**:
- Constipation is a condition characterized by infrequent bowel movements and difficulty in passing stools. It often results from a poor diet, lack of fiber, and dehydration.

2. **Role of Purgatives**:
- Purgatives are substances used to stimulate bowel movements. They help in the evacuation of feces by increasing intestinal peristalsis (the wave-like muscle contractions that move food through the digestive tract).

3. **Types of Purgatives**:
- There are various types of purgatives, but those that are commonly used for acute constipation often contain specific salts.

4. **Salts Used in Purgatives**:
- The salts that are commonly found in purgatives include sodium, magnesium, potassium, and calcium. Each of these salts can have different effects on the body.

5. **Magnesium Salts as Osmotic Laxatives**:
- Among these salts, magnesium salts are particularly effective as osmotic laxatives. They work by drawing water into the intestines, which increases the fluidity and volume of the intestinal contents, making it easier to pass stool.

6. **Conclusion**:
- Therefore, in the context of acute constipation, the purgatives that stimulate intestinal peristalsis and facilitate the evacuation of fluid feces primarily contain salts of magnesium.

**Final Answer**: The purgatives that are common to stimulate intestinal peristalsis and evacuation of fluid feces contain salts of **magnesium**.
