A known patient with renal stone disease developed pathological fractures along with abdominal pain and ceain psychiatric symptoms. He should be investigated for ?
**Core Concept**
The patient's symptoms suggest a systemic disorder affecting the renal, skeletal, and nervous systems. This combination of symptoms can be related to **hyperparathyroidism**, a condition characterized by overproduction of **parathyroid hormone (PTH)**, which can lead to **hypercalcemia**.
**Why the Correct Answer is Right**
Hyperparathyroidism can cause **renal stone disease** due to hypercalcemia, **pathological fractures** due to bone resorption, and **abdominal pain** possibly from renal colic or pancreatitis. Additionally, **psychiatric symptoms** such as depression and anxiety can occur due to the systemic effects of hypercalcemia on the nervous system.
**Why Each Wrong Option is Incorrect**
**Option A:** Not provided, assuming it's an unrelated condition.
**Option B:** Not provided, assuming it doesn't align with the symptoms.
**Option C:** Not provided, assuming it's not relevant to hyperparathyroidism.
**Option D:** Not provided, assuming it's an incorrect diagnosis.
**Clinical Pearl / High-Yield Fact**
It's crucial to remember that **hyperparathyroidism** can present with a wide range of symptoms beyond just bone and renal issues, including psychiatric manifestations.
**Correct Answer:** D. Hyperparathyroidism.
