Hypokalemia is caused by deficiency of which mineral

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Hypokalemia**: Hypokalemia is a medical condition characterized by low levels of potassium in the blood. It is important to identify the mineral deficiency that leads to this condition.

2. **Analyzing the Options**:
- **Option A: Calcium**: Calcium is essential for strong bones and teeth, muscle function, and nerve signaling. However, it is not directly related to hypokalemia.
- **Option B: Sodium**: Sodium helps maintain fluid balance and is crucial for nerve and muscle function. While sodium is important, it does not cause hypokalemia.
- **Option C: Potassium**: Potassium is vital for nerve function, muscle contraction, and maintaining a regular heartbeat. A deficiency in potassium directly leads to hypokalemia.
- **Option D: Phosphorus**: Phosphorus plays a role in bone formation and energy metabolism but is not related to potassium levels.

3. **Conclusion**: Based on the analysis, the mineral deficiency that causes hypokalemia is potassium.

**Final Answer**: Hypokalemia is caused by a deficiency of potassium.
