A person excretes more and dilute urine but amount of glucose in urine is absent. The person is suffering from -

Options

A. Diabetes insipidus
B. Diabetes mellitus
C. Myasthenia gravis
D. Cushing syndrome

Answer

To solve the question, we need to analyze the symptoms presented and match them with the correct medical condition.

### Step-by-Step Solution:

1. **Understand the Symptoms**: The question states that the person excretes more and dilute urine, and there is an absence of glucose in the urine.

2. **Identify the Options**: The options given are:
- A) Diabetes Insipidus
- B) Diabetes Mellitus
- C) Myasthenia Gravis
- D) Cushing Syndrome

3. **Analyze Each Option**:
- **Diabetes Insipidus**: This condition is characterized by excessive urination (polyuria) and dilute urine due to a deficiency of the antidiuretic hormone (ADH or vasopressin). There is typically no glucose present in the urine.
- **Diabetes Mellitus**: This condition is characterized by high blood sugar levels, leading to glucose spilling into the urine (glucosuria). This does not match the symptom of absent glucose in urine.
- **Myasthenia Gravis**: This is an autoimmune disorder that affects nerve impulses to muscles, leading to weakness. It does not relate to urine output or glucose levels.
- **Cushing Syndrome**: This condition results from excessive cortisol levels, which can lead to various symptoms, but it is not characterized by the symptoms mentioned in the question.

4. **Conclusion**: Based on the analysis, the only condition that matches the symptoms of more dilute urine and absence of glucose is **Diabetes Insipidus**.

### Final Answer:
The person is suffering from **Diabetes Insipidus**.
