CALCITONIN AND PARATHYROID HORMONES

PARATHYROID

• Parathyroid hormones are produced in the parathyroid glands
• Parathyroid hormone regulates the amount of calcium in the blood
• The parathyroid hormone is located on the posterior surface of the thyroid gland

PARATHYROID

• If calcium levels in the blood are too low then parathyroid hormones move calcium from the bones to the blood
• Parathyroid is opposite of calcitonin
• Parathyroid keeps the balance of calcium in the blood constant

HYPERSECTRETION

• Symptoms of hypersecretion are:
• High blood calcium
• Osteitis fibrosa cystica
• Tetany in skeletal muscles
• Can cause cardiac arrhythmia
• Osteoporosis can occur

HYPOSECRETION AND TREATMENT

• There is no easy way to tell if you're parathyroid gland is hypo-secreting other than testing the blood calcium levels
• Some rare symptoms can occur such as tingling hands and fingers or muscle cramps
• Treatment for both hyposecretion and hypersecretion is to remove the parathyroid glands

CACLITONIN

• Calcitonin is a hormone produced by C cells in the thyroid gland
• Calcitonin primarily targets the kidneys
• Calcitonin regulates the level of calcium in the blood by holding back calcium
• If blood calcium levels are high then calcitonin is triggered to restrict the levels of calcium in the blood

HYPERSECRETION/HYPOSECRETION AND TREATMENT

• Usually caused by thyroid cancer and it causes low blood calcium and muscles cramps
• Hyposecretion is usually caused by thyroid cancer as well and symptoms of that can be high blood calcium levels and osteoporosis which causes frail bones that lack calcium
• Parathyroid hormone and calcitonin work opposite of one another
• Just as with parathyroid hormone the best treatment option is to remove the thyroid gland
