What happens if calcitonin levels rise?

If calcitonin levels rise, it can lead to a condition called hypocalcemia, which is characterized by low levels of calcium in the blood. Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. When calcitonin levels are elevated, it can interfere with the body's ability to maintain normal calcium levels, resulting in hypocalcemia.

Symptoms of hypocalcemia can include:

- Muscle weakness

- Fatigue

- Tingling or numbness in the hands and feet

- Muscle cramps

- Seizures

- Confusion

- Difficulty concentrating

- Dry skin

- Brittle nails

- Hair loss

In severe cases, hypocalcemia can be life-threatening if left untreated. Treatment typically involves taking calcium supplements and addressing the underlying cause of the elevated calcitonin levels, which can include conditions such as medullary thyroid cancer, chronic kidney disease, or certain genetic disorders.
