Owing to its reduced bone density and higher risk for fractures, osteoporosis remains an international public health crisis. Research highlights the essential role played by macrophage polarization in osteoporosis and indicates that the balance between pro-inflammatory M1 macrophages and anti-inflammatory M2 macrophages influences bone metabolism. This review examines how M1 and M2 macrophages contribute to the development of osteoporosis and evaluates existing therapeutic approaches aimed at controlling macrophage polarization. It also describes future study areas that will allow improved management and treatment of osteoporosis.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
