I. Is osteoporosis just a symptom of natural aging? Osteoporosis was once thought to be an unavoidable part of human aging, especially in women, but we have now changed that perception. Osteoporosis is actually as prevalent in the elderly as heart disease, and can have serious consequences. However, the risk of developing this disease can be reduced through active prevention and treatment. Therefore, osteoporosis is not a symptom of natural aging. Can I get kidney stones from a high-calcium diet? A high-calcium diet can prevent osteoporosis, but many people are concerned about the possibility of kidney stone disease due to the deposition of high-calcium foods in the body. The answer is yes, excessive calcium supplementation can increase the burden on the kidneys and lead to stone disease. Because calcium is not so easily absorbed by the body, if too much is consumed but not absorbed, and oxalic acid is consumed at the same time, it may combine to form calcium oxalate stones. For patients with osteoporosis, calcium supplements should not be left out, but they should not be over-supplemented. Therefore, calcium supplements must be taken under the guidance of a doctor, and it is not recommended to abuse them on your own, and try to avoid the intake of spinach and other vegetable foods with high oxalic acid content during the calcium supplementation process. Third, what is the difference between osteoporosis and osteopenia? In osteoporosis, only a decrease in bone mass and structural disorders of bone trabeculae are found in imaging examinations, or slight changes in blood calcium, phosphorus and alkaline phosphatase levels in laboratory tests, and the human body in osteoporosis does not have obvious self-conscious symptoms. Osteoporosis is a phenomenon that indicates that abnormalities in bone metabolism have occurred in the human body, and is a sign of low bone mass in the body and a warning “yellow light” for the possible development of osteoporosis. If you continue to live an unscientific lifestyle and reduce your activities, you will have less muscle strength and less mechanical stimulation, and your bone mass may continue to decrease. When your bone mass decreases to a certain level, you will have low back pain (especially on both sides of the spine) and joint stiffness, which will be relieved when you are sitting on your back and increased after prolonged standing and exertion. In severe cases, pain can occur when bending, exercising or coughing, and even fractures can occur in minor collisions or falls. At this point, the disease has developed from osteoporosis to osteopenia, a difference in words, the disease has developed from the phenomenon to the essence.
