Why is PTH elevated in osteoporosis?
When one of the parathyroid glands is overactive (hyperparathyroidism) the parathyroid tumor makes too much PTH hormone which then causes our bones to release calcium constantly into the blood stream. This causes the bones to lose their density and hardness (it is the calcium that makes them hard).
How does parathyroid hormone affect bone?
Bones – parathyroid hormone stimulates the release of calcium from large calcium stores in the bones into the bloodstream. This increases bone destruction and decreases the formation of new bone.
How does PTH stimulate bone formation?
Intermittent administration of parathyroid hormone (PTH) stimulates bone formation on the surface of cancellous and periosteal bone by increasing the number of osteoblasts. … Thus, intermittent PTH does not increase cancellous or periosteal osteoblast number by stimulating the proliferation of osteoblast progenitors.
How do PTH analogs work?
Parathyroid hormone (PTH) analogues increase bone strength primarily by stimulating bone formation, whereas antiresorptive drugs (bisphosphonates) reduce bone resorption.
What happens if hyperparathyroidism is left untreated?
The effects of hyperparathyroidism can result in other health concerns, if left untreated. In addition to kidney stones and osteoporosis, older patients may physical symptoms including depression, mood changes, fatigue, muscle, and bone aches and pains, or even cardiac dysrhythmias.

What is the difference between osteoclast and osteoblast?
OSTEOCLASTS are large cells that dissolve the bone. … They are found on the surface of the bone mineral next to the dissolving bone. OSTEOBLASTS are the cells that form new bone. They also come from the bone marrow and are related to structural cells.
