Question: Which cells are defective in osteoporosis?

·

What cells are involved in osteoporosis?

Bone remodeling occurs in two phases. First, special bone cells called osteoclasts break down bone. Then, other bone cells called osteoblasts create new bone.

What cell causes osteoporosis?

Excessive bone breakdown by osteoclasts is an important cause of bone fragility not only in osteoporosis, but also in other bone diseases such as hyperparathyroidism, Paget’s disease, and fibrous dysplasia (see Chapter 3).

How are osteoblasts and osteoclasts related to osteoporosis?

Bone homeostasis depends on the resorption of bone by osteoclasts and formation of bone by osteoblasts. Imbalance of this tightly coupled process can cause diseases such as osteoporosis. Thus, the mechanisms that regulate communication between osteoclasts and osteoblasts are critical to bone cell biology.

What is the best doctor to treat osteoporosis?

Rheumatologists treat patients with age-related bone diseases. They can diagnose and treat osteoporosis. Endocrinologists, who see patients with hormone-related issues, also manage the treatment of metabolic disorders such as osteoporosis. Orthopedic surgeons may fix fractures.

What occurs in osteoporosis?

Osteoporosis literally means ‘bones with holes’. It occurs when bones lose minerals such as calcium more quickly than the body can replace them. They become less dense, lose strength and break more easily.

Which bone cell is responsible for osteoporosis?

Osteocytes, which are terminally differentiated osteoblasts embedded in mineralized bone, direct the timing and location of bone remodeling. In osteoporosis, the coupling mechanism between osteoclasts and osteoblasts is thought to be unable to keep up with the constant microtrauma to trabecular bone.

What can an endocrinologist do for osteoporosis?

Endocrinologists specialize in treating and preventing bone loss and preventing fractures. In addition, endocrinologists treat disorders that may affect bones, such as hyperparathyroidism, low and high levels of calcium. Become familiar with osteoporosis risk factors.

Is bone resorption good or bad?

This is a natural process that’s important for your health and wellbeing. But when resorption happens at a higher rate than it can be replaced, it can lead to a decrease in your bone mass and put you at higher risk for fractures and breakage.

What is the cellular mechanism of osteoporosis?

Osteoporosis is a metabolic bone disease that, on a cellular level, results from osteoclastic bone resorption not compensated by osteoblastic bone formation. This causes bones to become weak and fragile, thus increasing the risk of fractures.

How does estrogen affect osteoporosis?

Women tend to have smaller, thinner bones than men. Estrogen, a hormone in women that protects bones, decreases sharply when women reach menopause, which can cause bone loss. This is why the chance of developing osteoporosis increases as women reach menopause.

Is sitting bad for osteoporosis?

“If you have low bone density, however, and you put a lot of force or pressure into the front of the spine — such as in a sit-up or toe touch — it increases your risk of a compression fracture.” Once you have one compression fracture, it can trigger a “cascade of fractures” in the spine, says Kemmis.

What are the two medications that may cause osteoporosis after long term use?

The medications most commonly associated with osteoporosis include phenytoin, phenobarbital, carbamazepine, and primidone. These antiepileptic drugs (AEDs) are all potent inducers of CYP-450 isoenzymes.
