The parathyroid glands are four small glands located behind the thyroid gland in the neck. They play a critical role in regulating calcium and phosphorus levels in the body, which are essential for bone health, nerve function, and muscle contraction. The parathyroid glands produce parathyroid hormone (PTH), which helps increase calcium levels in the blood by stimulating calcium release from bones and enhancing calcium absorption in the intestines.

Maintaining healthy parathyroid gland function is crucial for preventing disorders like hyperparathyroidism (excess PTH production) or hypoparathyroidism (insufficient PTH production). A balanced diet rich in calcium and vitamin D supports parathyroid function and bone health. Regular physical activity and adequate sunlight exposure also contribute to calcium metabolism.

Common parathyroid gland issues include kidney stones, osteoporosis, and bone pain due to calcium imbalance. Symptoms such as fatigue, muscle weakness, and changes in mood should be evaluated by a healthcare provider.
