Osteoporosis is a metabolic disease, one of the common chronic and multi-morbid diseases, which is caused by the decrease of bone mineral content due to the factors of increasing age, disease, medication, nutrition, and less outdoor activities. In severe cases, there are symptoms such as bone pain and fractures. When you have osteoporosis, you have pain around your body and often start to seek medical treatment only after a fracture occurs. The World Health Organization reports that osteoporosis is second only to cardiovascular disease in severity, and that 1/3 of women and 1/5 of men over the age of 50 worldwide are threatened by osteoporosis. A statistical study of more than 5,000 cases of people over 40 years old in five regions of China showed that the prevalence of osteoporosis was 16.1%, with more than 50% of women aged 60 to 70 suffering from osteoporosis and nearly 2/3 of those over 80 years old suffering from osteoporosis.
