With the aging of the population, osteoporosis has become a worldwide and increasingly important health problem. The so-called osteoporosis is a systemic disease characterized by a decrease in bone mass and destruction of bone tissue structure. The most common form of osteoporosis occurs in older women because after menopause, the level of estrogen in the body decreases, and calcium, which maintains bone strength, is lost from the bones to the blood. At this time, bones become brittle and their original compact structure gradually becomes porous, leading to an increased risk of fracture. Medication-induced (e.g. overuse of hormones) and aging are also important factors. Common symptoms of osteoporosis include: 1. Shortening of height. This is generally characterized by a shortening of height by more than 3cm. 2. Low back pain. Pain is the most common symptom of osteoporosis patients and is the reason why many elderly people visit the clinic.3. Osteoporotic fracture. This is the most feared point of osteoporosis, and also the point that osteoporosis patients should do their best to prevent. How to prevent and control it: 1, a balanced diet rich in calcium, if necessary, appropriate amount of calcium supplements. 2, more sunshine to promote calcium absorption, appropriate exercise to promote the body’s metabolism. 3, drug prevention and control: oral bisphosphonates. This type of drug is the first line of effective prevention and treatment of osteoporosis, which can reduce the risk of fracture by 90%, of which the first line of clinical drugs is sodium alanophosphate. 4, adhere to the regular review, adhere to long-term treatment. It is recommended to go to a standardized hospital, follow the doctor’s instructions, adhere to standardized medication, and ultimately overcome osteoporosis.
