If the sugar level of blood is blood is too high , it can be reduced immediately by

Options

A. oral insulin
B. oral glucagon
C. intravenous insulin
D. intravenous glucagon

Answer

To solve the question regarding how to immediately reduce high blood sugar levels, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Blood Sugar Regulation**:
- The pancreas plays a crucial role in regulating blood sugar levels through the secretion of hormones, primarily insulin and glucagon.

2. **Role of Insulin and Glucagon**:
- Insulin decreases blood sugar levels by facilitating the uptake of glucose into cells, while glucagon increases blood sugar levels by promoting the release of glucose from the liver.

3. **Identifying the Correct Hormone**:
- Since the question asks how to reduce high blood sugar levels, we need to focus on insulin, as it is the hormone responsible for lowering blood glucose.

4. **Forms of Insulin Administration**:
- Insulin can be administered in various forms, but it is important to note that insulin is not effective when taken orally due to its breakdown in the digestive system.

5. **Choosing the Right Method of Administration**:
- The most immediate and effective way to administer insulin when blood sugar levels are high is through an intravenous (IV) injection. This allows for rapid action in lowering blood sugar levels.

6. **Conclusion**:
- Therefore, the correct answer to the question is "intravenous insulin," as it is the most effective method to quickly reduce high blood sugar levels.

### Final Answer:
**Intravenous insulin**
