Parathyroid glands regulate calcium and phosphorous homeostasis in body. There can be hypo and hyper functioning of these glands resulting in calcium disturbances. Hypoparathyroidism can cause decrease in calcium- calcification in different body parts, seizures, tetany, spasms etc. hyperparathyroidism can cause increased calcium, bone loss and fractures.
As an endocrinologist, we deal with these parathyroid related disorders.
