Bone loss is clinically more common in two groups of people, first, women during pregnancy. Secondly, middle-aged and old-aged patients, both of which have a more pronounced decrease in bone mass. If calcium is not supplemented in time a series of symptoms of bone loss will occur. Take the elderly as an example, especially middle-aged and elderly women, there can be cervical pain, lumbar and leg pain, there can be excessive sweating as well as limb soreness, and women who are pregnant will have tooth pain as well as leg soreness and cramps. If these two types of patients experience a decrease in bone mass, they can take more food with a higher calcium content to alleviate their symptoms, such as sesame and peanut butter as well as lamb, milk and walnuts, which are calcium-supplemented foods. If the osteoporosis is more serious, you can go to the hospital to measure the bone density, check the degree of osteoporosis, and choose to treat it with medication.
