Osteoporosis is a systemic disease characterized by a decrease in bone mass and destruction of the microstructure of bone tissue, resulting in “brittle” bones that are prone to fractures. With the aging of the population, osteoporosis has become a common and frequent disease, which is more common in post-menopausal women and men over 60 years old. It has many harmful effects on human health, such as back pain, shortening of height and hunchback, which affect the quality of life. For example, compression fracture of the spine can cause severe back pain and even difficulty in turning over. The most terrible thing about osteoporosis is the occurrence of hip (such as femoral neck) fracture, and 1/3 of patients are disabled and cannot take care of themselves, so the occurrence of osteoporotic hip fracture is considered to ring the death knell of the elderly. Osteoporotic fractures are often characterized as “fragility fractures” that occur with minor violence or in the course of daily life. One of our outpatients had a lumbar fracture just from picking up a piece of laundry to dry, and the fracture occurred twice. Some elderly people fracture their bones while squatting in the toilet or tying their shoelaces. In severe cases, the fracture can even occur with a cough. Another characteristic of this fragility fracture is that it can occur repeatedly, which means that after one fracture, the risk of another fracture in a different area is greatly increased. Therefore, early diagnosis and treatment of osteoporosis is especially important, not only to improve the quality of life of patients, but also to prevent fractures from occurring. We often see stalls for free bone density measurement in front of certain neighborhoods or health food stores. Most of these are single photon bone densitometers invented in the 1960s, which use isotopes as the ray source, and the instability of the ray source occurs due to the decay of the isotopes, resulting in inaccurate measurement results, which cannot be used to diagnose osteoporosis according to this. According to the World Health Organization, the diagnosis of osteoporosis should use dual-energy X-ray absorptiometry to determine bone density, which has been introduced into China for about 10 years and is a non-invasive examination that takes only a few minutes and receives only one-tenth of the radiation of a chest X-ray in one examination. It can be used not only to diagnose osteoporosis, but also to predict the possibility of fracture and as an important indicator for the observation of the efficacy of anti-osteoporosis drugs. At present, only 2 hospitals in Daqing have this kind of equipment, so you should go to a regular hospital with the above mentioned tests for osteoporosis. Osteoporosis can not just take some calcium tablets, we should know that in addition to primary osteoporosis caused by menopause and old age, there are also secondary osteoporosis, which can be caused by other diseases, such as hyperparathyroidism, malignant tumors, blood diseases, etc. These diseases are often insidious and not easily detected, but the consequences are serious, so ordinary low back pain may be lurking a great Therefore, ordinary low back pain may be a great crisis, and should not be taken lightly, and should be diagnosed in a regular hospital as early as possible, so as to win valuable time for the best treatment. At the same time, for primary osteoporosis, formal treatment must also be carried out under the guidance of a doctor. There are many effective drugs available, which can not only significantly relieve symptoms such as low back pain and maximize the quality of life; but also reduce bone loss and prevent fractures.
