Which of the following is a hyperglycemia hormone ?

Options

A. Glucagon
B. Insulin
C. Aldosterone
D. Androgen

Answer

To determine which of the following is a hyperglycemic hormone, we need to understand what hyperglycemic means. A hyperglycemic hormone is one that increases blood glucose levels.

### Step-by-Step Solution:

1. **Understand Hyperglycemic Hormones**:
- Hyperglycemic hormones are those that increase the concentration of glucose in the blood.

2. **Evaluate Each Option**:
- **Option A: Glucagon**:
- Glucagon is secreted by the alpha cells of the pancreas.
- It promotes glycogenolysis (the breakdown of glycogen into glucose) and gluconeogenesis (the formation of glucose from non-carbohydrate sources).
- Since glucagon increases blood glucose levels, it is a hyperglycemic hormone.

- **Option B: Insulin**:
- Insulin is secreted by the beta cells of the pancreas.
- It promotes glycogenesis (the conversion of glucose to glycogen) and lowers blood glucose levels.
- Therefore, insulin is a hypoglycemic hormone, not hyperglycemic.

- **Option C: Aldosterone**:
- Aldosterone is secreted by the adrenal cortex and is primarily involved in regulating electrolyte balance, particularly sodium and potassium levels.
- It does not have a direct role in increasing blood glucose levels, making it an incorrect option.

- **Option D: Androgens**:
- Androgens are male sex hormones produced by the adrenal glands and are involved in reproductive development.
- They do not influence blood glucose levels, so this option is also incorrect.

3. **Conclusion**:
- Based on the evaluations, the only hormone that is hyperglycemic is **Glucagon**.

### Final Answer:
**Glucagon** is the hyperglycemic hormone.
