[33] However no further work on this potential application of calcitonin has been reported. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to increased osteoblastic activity (as an indirect effect). Scientists mainly know this because having high or low levels of PTH can cause hypercalcemia (high blood calcium levels) or hypocalcemia (low blood calcium levels), respectively, which can be serious conditions. E) enhance the reabsorption of calcium at the kidneys. Having too much of the hormone can cause a condition known as hypercalcaemia, which increases blood calcium levels.
