The parathyroid glands are responsible for the normal production of calcium in different parts of the body. Insufficiency of parathyroid hormones causes a lack of supply of calcium in the body which affects a person’s nerve and muscle functions. Too much parathyroid hormone can lead to kidney problems, chronic fatigue, osteoporosis, and other issues in the body. Having a parathyroid abnormality such as a parathyroid tumor can lead to the above abnormalities. This needs to be checked by a specialist for proper management.
