Oversecretion of glucagon causes :

Options

A. Tetany
B. Diabetes insipidus
C. Acromegaly
D. Glycosuria

Answer

**Step-by-Step Solution:**

1. **Understanding Glucagon:** Glucagon is a hormone produced by the alpha cells of the pancreas. Its primary function is to increase blood glucose levels by promoting the conversion of glycogen to glucose in the liver and stimulating gluconeogenesis.

2. **Identifying the Effects of Glucagon Overproduction:** When there is oversecretion of glucagon, it leads to elevated blood glucose levels. This condition can cause various metabolic disturbances.

3. **Analyzing the Options:**
- **Tinnitus:** This condition is related to ear issues and is not associated with glucagon levels.
- **Diabetes Insipidus:** This is a condition characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone (ADH), not glucagon.
- **Acromegaly:** This condition is caused by excess growth hormone and is unrelated to glucagon.
- **Glycosuria:** This refers to the presence of glucose in the urine, which can occur due to high blood glucose levels resulting from glucagon oversecretion.

4. **Conclusion:** The oversecretion of glucagon primarily leads to glycosuria due to increased blood glucose levels, which the kidneys cannot reabsorb completely, resulting in glucose being excreted in urine.

**Final Answer:** Oversecretion of glucagon causes glycosuria.
