The correct answer is loss of bone calcium. Osteoporosis is a condition characterized by weak and brittle bones, which are more susceptible to fractures. It occurs when the body loses bone tissue faster than it can be replaced, leading to a decrease in bone density and strength. One of the main contributing factors to this loss of bone tissue is the loss of calcium from the bones. Calcium is an essential mineral that helps maintain the strength and density of our bones. When calcium levels in the body are low, the body may begin to take calcium from the bones, making them weaker over time. There are several risk factors that can increase the likelihood of developing osteoporosis, such as age, gender (women are more prone to it), genetics, hormonal imbalances, and certain medical conditions or medications. It is important to maintain a healthy lifestyle, including a balanced diet rich in calcium and vitamin D, regular exercise, and avoiding habits like smoking or excessive alcohol consumption, in order to reduce the risk of osteoporosis. Consulting with a healthcare professional is also recommended for proper diagnosis, management, and prevention.
Osteoporosis is primarily caused by the loss of bone calcium. This depletion of calcium weakens the bones and makes them more susceptible to fractures. Dementia, arthritis, and loss of brain cells are not known to be direct causes of osteoporosis.
