In diabetes mellitus the patient drink more water as there is urinary loss of

Options

A. Salt
B. Insulin
C. Protein
D. Glucose

Answer

**Step-by-Step Solution:**

1. **Understanding Diabetes Mellitus:**
- Diabetes mellitus is a metabolic disorder characterized by high blood sugar levels due to the body's inability to produce or effectively use insulin.

2. **Role of Insulin:**
- Insulin is a hormone that helps convert sugars, starches, and food into energy. In diabetes, the lack of insulin or ineffective use of it leads to elevated glucose levels in the blood.

3. **Symptoms of Diabetes:**
- Two classic symptoms of diabetes mellitus are increased thirst (polydipsia) and frequent urination (polyuria). These symptoms arise due to high glucose levels in the bloodstream.

4. **Mechanism of Increased Urination:**
- When blood glucose levels are high, the kidneys work harder to filter out the excess glucose. This process requires more water, leading to increased urine production.

5. **Fluid Loss and Thirst:**
- As the kidneys filter out glucose, they also pull more fluids from other tissues, which results in the body losing more water. This loss of fluid triggers the sensation of thirst, prompting the patient to drink more water.

6. **Identifying the Correct Answer:**
- The question asks what is lost in the urine in diabetes mellitus. Given the options (salt, insulin, protein, glucose), the correct answer is glucose, as it is the primary substance lost in the urine due to the kidneys' attempts to filter excess glucose from the blood.

**Final Answer:**
- In diabetes mellitus, the patient drinks more water due to urinary loss of **glucose**.
