Primary hyperparathyroidism (pHPT) is a condition where one or more parathyroid glands produce excessive parathyroid hormone (PTH), leading to elevated blood calcium levels. The most common cause is a benign tumor (adenoma). Symptoms include bone pain, kidney stones, muscle weakness, and mental changes. Diagnosis involves blood tests and imaging, with treatment often being surgical removal of the affected glands.

Details:
Primary hyperparathyroidism occurs when one or more parathyroid glands overproduce PTH, resulting in hypercalcemia (elevated calcium levels in the blood).

Causes:

• Benign Tumors (Adenomas): Most common cause.
• Hyperplasia: Enlargement of all four glands (less common).
• Malignant Tumors (Carcinomas): Rare cause.

Symptoms:

• Bone Pain and Osteoporosis: Excessive bone resorption increases fracture risk.
• Kidney Stones: Elevated calcium levels lead to stone formation.
• Muscle Weakness and Fatigue: Due to impaired muscle and nerve function.
• Gastrointestinal Issues: Nausea, vomiting, constipation, and appetite loss.
• Psychological Changes: Depression, irritability, and concentration difficulties.

Diagnosis:

• Blood Tests: Show elevated calcium and PTH levels.
• Imaging: Ultrasound or scintigraphy to identify enlarged or tumor-affected glands.

Treatment:

• Surgery: Removal of affected glands (parathyroidectomy).

Mild Cases: Close monitoring and medications to lower calcium levels, especially in asymptomatic cases
