Symptoms like acidosis, polydipsia and polyphagia are associated with

Options

A. Hypersecretion of STH
B. Hyposecretion fof glucagon
C. Hypersecretion of insulin
D. Hyposecretion of insulin

Answer

To solve the question regarding the symptoms of acidosis, polydipsia, and polyphagia, we will analyze each symptom and its association with hormonal secretion.

### Step-by-Step Solution:

1. **Understanding the Symptoms**:
- **Acidosis**: This refers to an increase in acidity in the blood, often due to the accumulation of acidic compounds.
- **Polydipsia**: This is characterized by excessive thirst or a strong need to drink fluids.
- **Polyphagia**: This means increased appetite or excessive eating.

2. **Identifying the Condition**:
- The combination of these symptoms is typically associated with **hyperglycemia**, which is an elevated level of glucose in the blood.

3. **Connecting Symptoms to Diabetes**:
- Prolonged hyperglycemia leads to a condition known as **Diabetes Mellitus**. In this condition, the body cannot effectively utilize glucose, leading to its loss through urine and the formation of harmful acidic compounds.

4. **Role of Insulin**:
- Insulin is a hormone produced by the pancreas that helps lower blood glucose levels. When insulin secretion is inadequate (hyposecretion), glucose levels rise, leading to hyperglycemia.

5. **Evaluating the Options**:
- **Hypersecretion of STH (Somatotropic Hormone)**: This does not relate to the symptoms as it does not directly influence glucose levels.
- **Hyposecretion of Glucagon**: Glucagon raises blood glucose levels; thus, its deficiency would not cause hyperglycemia.
- **Hypersecretion of Insulin**: This would lower glucose levels, not raise them.
- **Hyposecretion of Insulin**: This is the correct option. If there is less insulin, glucose levels will increase, leading to the symptoms mentioned.

6. **Conclusion**:
- The correct answer is **Hyposecretion of Insulin**, as it directly leads to the symptoms of acidosis, polydipsia, and polyphagia due to increased blood glucose levels.

### Final Answer:
The symptoms like acidosis, polydipsia, and polyphagia are associated with **Hyposecretion of Insulin**.
