Which of the following disorders is characterised by bronze pigmentation of skin, low Na^+ and blood sugar levels, high K^+ level and nausea?

Options

A. Conn's syndrome
B. Guli's disease
C. Addison's disease
D. Cushing's disease

Answer

To solve the question regarding the disorder characterized by bronze pigmentation of the skin, low sodium (Na^+), low blood sugar, high potassium (K^+), and nausea, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Symptoms**: The question lists several symptoms: bronze pigmentation of the skin, low sodium levels, low blood sugar levels, high potassium levels, and nausea. We need to find a disorder that matches all these symptoms.

2. **Review Options**: The options provided in the question are:
- Kohn's syndrome
- Girl's disease
- Addison's disease
- Cushing's disease

3. **Analyze Each Option**:
- **Kohn's Syndrome**: This condition is associated with increased adrenaline levels, which typically leads to increased sodium retention and blood pressure, not low sodium or blood sugar levels. Therefore, it does not match the symptoms.
- **Girl's Disease**: This condition involves degeneration related to thyroid hormone, which does not correlate with the symptoms listed, particularly the bronze pigmentation and electrolyte imbalances. Thus, it is not the correct choice.
- **Addison's Disease**: This disorder is characterized by adrenal insufficiency. It leads to low sodium levels, low blood sugar levels, high potassium levels, and can cause hyperpigmentation of the skin (bronze coloration). This aligns perfectly with the symptoms given in the question.
- **Cushing's Disease**: This condition is caused by elevated cortisol levels, which typically leads to symptoms such as weight gain and changes in skin coloration (not bronze). It does not match the symptoms of low sodium and blood sugar levels.

4. **Conclusion**: Based on the analysis, Addison's disease is the only disorder that fits all the symptoms described in the question.

### Final Answer:
The correct answer is **Addison's disease**.
