Hair loss can be a perplexing and distressing experience, and it can sometimes be a symptom of underlying health conditions. One such condition is parathyroid disease. This article aims to shed light on the question: can parathyroid cause hair loss?

Can Parathyroid Disease Cause Hair Loss?

Yes, parathyroid disease can cause hair loss. Both hyperparathyroidism and hypoparathyroidism have been associated with hair loss. The disruption of hormonal balance due to these conditions can interfere with the production of hormones essential for healthy hair growth, leading to hair loss. If untreated, the hair loss can become permanent, resulting in alopecia or bald spots. However, with prompt and effective treatment, the hair loss is usually reversible.

Understanding Parathyroid Disease

The parathyroid glands regulate calcium in the body by producing parathyroid hormone (PTH). Hyperparathyroidism, a condition where an enlargement of one or more of the parathyroid glands causes overproduction of PTH, can lead to high calcium levels in the blood, causing a variety of health problems, including hair loss. Hypoparathyroidism, on the other hand, involves deficiencies in PTH production, which can also lead to hair loss.

The Connection between Parathyroid Hormone and Hair Loss

Parathyroid hormone (PTH) plays a crucial role in regulating calcium in the body. Disruptions in PTH production due to parathyroid disease can lead to imbalances in the body's calcium levels. This can interfere with the production of certain hormones, such as testosterone and estrogen, which are important for hair growth. Additionally, research shows that PTH may directly impact hair follicle growth.

Managing Hair Loss Associated with Parathyroid Disease

If you're experiencing hair loss due to parathyroid disease, addressing the root cause — the parathyroid disease itself — is crucial. Proper medical treatment, which often involves surgery for hyperparathyroidism, can help manage the condition and potentially reverse hair loss. As always, it's important to consult with a healthcare professional for personalized advice.


In conclusion, parathyroid disease can indeed cause hair loss due to hormonal disruption and calcium imbalances in the body. If you're dealing with parathyroid disease and experiencing hair loss, reach out to a healthcare professional to discuss your symptoms and the best course of action. Remember, managing the underlying parathyroid disease is the first step to addressing associated hair loss.
