Insulin shock is due to

Options

A. Down-regulation of insulin-receptors
B. Up-regulation of insulin receptors
C. injuction of heavy dose of insulin
D. Low blood sugar level

Answer

**Step-by-Step Solution:**

1. **Understanding Insulin Shock**: Insulin shock, also known as hypoglycemia, occurs when there is a rapid drop in blood sugar levels. This condition can lead to various symptoms such as confusion, dizziness, and in severe cases, loss of consciousness.

2. **Identifying Causes**: The primary cause of insulin shock is an excess of insulin in the bloodstream, which can occur due to an injection of a heavy dose of insulin. However, the underlying issue that leads to the symptoms is the resultant low blood sugar level.

3. **Analyzing the Options**:
- **Option 1: Down regulation of insulin receptors** - This refers to a decrease in the number of insulin receptors, which is not directly related to insulin shock.
- **Option 2: Up regulation of insulin receptors** - This means an increase in the number of insulin receptors, which also does not cause insulin shock.
- **Option 3: Injection of heavy dose of insulin** - While this can lead to low blood sugar, it is not the direct cause of insulin shock; rather, it is a contributing factor.
- **Option 4: Low blood sugar level** - This is the direct cause of insulin shock, as it results in the symptoms associated with the condition.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 4: Low blood sugar level**. This condition triggers the release of epinephrine (adrenaline) as a response to counteract the low glucose levels, leading to the symptoms of insulin shock.
