Osteoporosis is a group of bone diseases caused by multiple causes and is a metabolic bone lesion characterized by a decrease in the amount of bone tissue per unit volume. In most cases of osteoporosis, the decrease in bone tissue is mainly due to increased bone resorption. The onset of the disease is mostly slow, but individually faster, characterized by skeletal pain and easy fracture. Biochemical examination is basically normal. Pathological anatomy shows thin bone cortex and sparse atrophy of bone trabeculae. Common symptoms: ① Pain is the most common symptom of primary osteoporosis, with low back pain being the most common, accounting for 70% to 80% of the patients with pain. ②Shortening of body length and hunchback, mostly appearing after pain. ③Fracture is the most common and serious complication of degenerative osteoporosis. How to prevent: ①Control the diet structure to avoid excessive intake of acid and aggravate the acidic body. Most vegetables and fruits are alkaline foods, while most meat, cereals, sugar, wine, fish and shrimp are acidic foods. Maintaining a weak alkaline environment in the human body can prevent and relieve osteoporosis. ② Quit smoking and control excessive alcohol consumption. ③Frequent and appropriate outdoor exercise. ④Keep a good mood and do not have excessive psychological stress. Non-pharmacologic treatment: ensure enough sleep, get one hour of sunshine every day, and exercise for half an hour or more every day. The more meaningful exercise methods for osteoporosis are walking, playing tai chi, doing various exercise exercises, and swimming if possible. Sunbathing and sports exercise first for a short time, then slowly increase and extend the exercise time. Treatment drugs: ① Bone peptide tablets: the drug can directly reach the site of osteoporosis, good targeting, containing a variety of bone growth factors. ②Alendronate: It has the effect of inhibiting osteoclasts and has the effect of preventing and treating osteoporosis at the same time. ③Migestat salmon calcitonin: regular subcutaneous intramuscular injection or nasal spray absorption, effective for osteoporosis patients. Now the new dosage form of Miguelin is effective for one year in one treatment, which is convenient for middle-aged and elderly osteoporosis patients. ④Calcium and vitamin D: combined medication is more effective.
