Does Parathyroid Disease Cause Hair Loss?

The parathyroid glands are small organs in the neck that maintain the body’s mineral balance. Many wonder if these glands contribute to unexplained symptoms like hair loss. This article explores the function of the parathyroid glands, the conditions that can affect them, and whether a connection exists between parathyroid disorders and hair health.

Understanding the Parathyroid Glands

Most individuals have four parathyroid glands, located behind the thyroid gland in the neck. These endocrine glands produce parathyroid hormone (PTH), which regulates calcium and phosphorus levels in the blood and bones. This regulation is important for various bodily functions, including nerve and muscle activity, blood clotting, and maintaining strong bones. When blood calcium levels decrease, the parathyroid glands release PTH, which signals bones to release calcium, kidneys to reabsorb it, and intestines to absorb more from food. Conversely, when calcium levels are high, PTH production decreases.

Parathyroid Conditions and Associated Symptoms

Disruptions in parathyroid gland function can lead to two primary conditions: hyperparathyroidism and hypoparathyroidism. Hyperparathyroidism occurs when one or more glands become overactive, producing excess PTH and leading to elevated calcium levels. Common symptoms of hyperparathyroidism include chronic fatigue, bone and joint pain, memory difficulties, increased thirst, frequent urination, and the formation of kidney stones. Conversely, hypoparathyroidism develops when glands produce insufficient PTH, resulting in low calcium and elevated phosphorus levels. Symptoms of hypoparathyroidism include tingling sensations in the lips, fingers, and toes, muscle cramps, spasms, and sometimes confusion.

Exploring the Connection to Hair Loss

While parathyroid disorders are not primarily known for causing hair loss, there can be indirect connections. In hyperparathyroidism, hair loss, including frontal scalp thinning in women, can be a sign, potentially linked to low calcium or vitamin D deficiency. Chronic, untreated hyperparathyroidism can also contribute to generalized hair thinning. In cases of hypoparathyroidism, individuals may experience dry, brittle, or coarse hair, and general hair loss, attributed to calcium imbalance as PTH plays a role in hair follicle health. However, hair loss is multifactorial; parathyroid conditions are less common causes compared to genetic predispositions, hormonal changes, nutritional deficiencies, or stress.

Diagnosis and Treatment of Parathyroid Disorders

Diagnosing parathyroid disorders involves blood tests to measure calcium, phosphorus, and parathyroid hormone (PTH). Imaging tests, such as ultrasound or sestamibi scans, may locate an affected gland.

Treatment approaches vary depending on the specific condition. For hyperparathyroidism, surgical removal of the overactive gland(s) is often the most effective treatment. In cases where surgery is not possible or desired, medications can help manage calcium levels. For hypoparathyroidism, treatment primarily involves lifelong supplementation with calcium and activated vitamin D to restore and maintain proper mineral balance.

While treating the underlying parathyroid condition is important for overall health, hair loss improvement is not always immediate or guaranteed. Consulting with a healthcare professional for accurate diagnosis and tailored management remains important.
