October 20 is World Osteoporosis Day, which was established by the British National Osteoporosis Society in 1996 and officially set as World Osteoporosis Day on October 20 every year with the participation and co-sponsorship of the World Health Organization in 1998. Statistics show that as of 2012, about 200 million people worldwide suffer from osteoporosis, ranking among the top 5 diseases of middle-aged and elderly people, and about 90 million people in China suffer from different degrees of osteoporosis, accounting for about 7% of the total population. Pain. Primary osteoporosis is the most common, mostly seen in low back pain, accounting for 70% to 80% of patients with pain. The pain spreads along the spine to both sides, decreases when lying on the back or sitting and standing, increases when posteriorly stretched when standing upright or when standing or sitting for a long time, is light during the day, increases at night and when waking up in the early morning, and increases when bending, muscle movement, coughing, and bowel straining. Bone pain generally occurs when bone mass is lost by 12% or more. In elderly osteoporosis, the vertebral trabeculae atrophy and decrease in number, the vertebral body compresses and deforms, the spine flexes forward, and the lumbar rash muscle doubles its contraction in order to correct the forward flexion of the spine, resulting in muscle fatigue and even spasm, producing pain. A recent compression fracture of the thoracolumbar spine may also produce acute pain. If the corresponding spinal nerve is compressed, radiating pain in the extremities, sensory-motor disorders in both lower extremities, intercostal neuralgia, retrosternal pain similar to angina pectoris, and epigastric pain similar to acute abdomen may occur. If the spinal cord and cauda equina are compressed, bladder and rectal function may also be affected. Early detection of bone densitometry can be used for people of any age to determine if a patient needs to take preventive measures against fractures. There are many drugs available for the treatment of osteoporosis, some of which have been shown to be effective in increasing resistance to fracture in randomized controlled studies, while others are still under further development. Non-pharmacologic therapies such as physical activity and nutritional diet plans can be very helpful in preventing postmenopausal or other types of osteoporosis and in improving quality of life. Bone density testing determines whether you want to be treated, bone densitometry commonly used are single photon, ultrasound and dual-energy x-ray bone densitometer TianxA) 3, with DXA as the best test means, can be fast, non-invasive, accurate quantitative. About 30% to 50% of patients with degenerative osteoporosis do not have significant bone pain. Bone densitometry can provide timely diagnosis of osteoporosis and indicate the risk of future fracture. Bone density testing is best done regularly. Calcium and vitamin D are essential nutrients to increase and maintain bone mass. Protein and other nutrients, such as phosphorus, sodium, magnesium and other minerals, also play an important role in maintaining bone health. For adults, the recommended daily intake of calcium is 080 mg. Milk and dairy products can be added to three meals. You can also eat more seafood, green leafy vegetables, nuts and dried fruits, as well as pork, eggs, beans, fish, etc. Avoid too much meat and salt, as too much protein and salt will accelerate calcium loss. Calcium and vitamin D supplements can be taken in moderation under the guidance of a doctor, especially for women after menopause. Among calcium supplements, the most used is calcium carbonate, but calcium carbonate is not suitable for patients with stomach acid deficiency. Organic acid calcium such as calcium raffinate, although lower in calcium content, is easier to dissolve than calcium carbonate and is suitable for patients with stomach acid deficiency. Calcium phosphate is not easy to dissolve and is not suitable for patients with chronic renal failure. For people with renal insufficiency or who need to restrict the intake of certain nutrients, be more careful when choosing. Can exercise help prevent “osteoporosis”? Exercise can significantly accelerate blood circulation throughout the body and bones, and muscle contraction and diastole can stop and slow down the process of osteoporosis.
