Hyperparathyroidism

Hyperparathyroidism is a condition characterized by an overproduction of parathyroid hormone (PTH) from the parathyroid glands. This excess PTH can lead to high levels of calcium in the blood, which can cause a variety of health problems.

Types

• There are two main types of hyperparathyroidism: primary and secondary.
• Primary hyperparathyroidism is caused by an enlargement or adenoma in one or more of the parathyroid glands. This leads to an overproduction of PTH and subsequent high calcium levels in the blood.
• Secondary hyperparathyroidism is a response to low calcium levels in the blood. This can be due to various reasons such as vitamin D deficiency, kidney disease, or dietary insufficiency. The low calcium levels stimulate the parathyroid glands to produce more PTH.

Symptoms

• Hyperparathyroidism can often be asymptomatic, especially in its early stages. When symptoms do occur, they may include:
• Fatigue or weakness
• Depression or forgetfulness
• Bone and joint pain
• Frequent urination
• Kidney stones
• Nausea, vomiting or loss of appetite

Diagnosis

Hyperparathyroidism is often diagnosed through blood tests that show high levels of PTH and calcium. Other tests, like bone density scans and kidney function tests, may also be used. In some cases, imaging tests can help identify an enlarged parathyroid gland.

Treatment

Treatment depends on the cause and severity of the condition. In primary hyperparathyroidism, surgery to remove the affected parathyroid gland(s) may be necessary. For secondary hyperparathyroidism, treatment typically involves addressing the underlying cause, such as increasing calcium or vitamin D intake or managing kidney disease.
