Osteoporosis is one of the problems that plague many modern people. Although our diet is becoming more and more nutritious, it is difficult to ensure that we can get enough calcium, because many poor lifestyles, the calcium that was originally eaten into the mouth but secretly flowed away, so we have to supplement calcium again. ”Osteoporosis is a silent, systemic disease of the skeletal system, called the “invisible epidemic” by the medical profession. There are no obvious symptoms at first, so it is easy to be ignored. The prevalence of osteoporosis increases year by year with the increase of age. According to statistics, the incidence of osteoporosis is as high as 50%-70% in elderly women aged 60-69, 30% in elderly men, and almost 100% in elderly women over 70 years old. Osteoporosis is particularly prevalent in older postmenopausal women, and it increases the risk of fracture, with hip and spine fractures clearly associated with a high prevalence and mortality in this population. For women over the age of 50, hip fractures have the same mortality rate as breast cancer and are 2-15 times higher than other gynecologic tumors. The dangers caused by osteoporotic fractures are actually the same as those caused by stroke and myocardial infarction, which should not be underestimated. Small fractures are like small strokes, while large fractures are like large strokes. Osteoporotic fractures often lead to lifelong disability or even life-threatening injuries. Calcium supplements can only prevent “osteoporosis” With the popularization of osteoporosis disease knowledge in recent years, public awareness of osteoporosis has increased significantly, but there are still many cognitive misconceptions about how to properly treat it. Many people believe that a high-calcium diet or calcium supplements on a daily basis can prevent or even treat osteoporosis, which is a serious misconception. The scary thing is that there are no warning signs of osteoporosis, and the first sign of the disease is usually a fracture, making prevention of another fracture the primary goal of treatment for patients with osteoporotic fractures. Lifestyle pathways alone may not be sufficient to prevent bone loss or reduce the risk of fracture; it is only the basis for the prevention and management of osteoporosis through a pharmacologic approach. Calcium supplementation alone is not sufficient to deal with osteoporosis, but rather timely prescription interventions to improve bone density and bone strength and thereby reduce the risk of fracture. In addition, some people worry that long-term calcium supplementation will lead to more stones, but in fact, there is no need to worry. It has been reported that calcium supplementation of 1500 mg/day for 4 years resulted in a lower incidence of stones than those with insufficient calcium intake. Currently, it is generally considered safe to take less than 2000mg of calcium per day.
