D. Thyroid hormone

Answer

To solve the question regarding the elevated hormone in a middle-aged woman experiencing irregular menses, weight loss, and recurrent diarrhea, we can follow these steps:

### Step 1: Identify the Symptoms
The woman presents with:
- Irregular menses
- Weight loss
- Recurrent diarrhea

### Step 2: Understand the Hormonal Influence
We need to determine which hormone could cause all three symptoms. The symptoms suggest a disruption in metabolic processes and possibly an imbalance in water and electrolytes.

### Step 3: Evaluate the Hormones
Let’s analyze the hormones mentioned:
1. **Cortisol**: Known as a stress hormone, it can affect metabolism but does not directly cause all three symptoms together.
2. **Aldosterone**: This hormone primarily regulates sodium and potassium levels in the kidneys. It does not directly relate to menstrual irregularities or weight loss.
3. **Melatonin**: This hormone regulates sleep-wake cycles and does not correlate with the symptoms presented.
4. **Thyroid Hormones**: These hormones (like T3 and T4) are crucial for regulating metabolism, energy levels, and can impact menstrual cycles, weight, and gastrointestinal function.

### Step 4: Conclusion
Given the symptoms and the hormonal functions:
- Irregular menses can be caused by thyroid dysfunction.
- Weight loss and diarrhea can also be linked to hyperthyroidism, where the metabolic rate is increased.

Thus, the hormone that the doctor is referring to is **Thyroid Hormone**.

### Final Answer
The hormone the doctor is talking about is **Thyroid Hormone**.
