Osteoporosis is a systemic bone disease characterized by low bone mass and damage to bone microstructure, leading to increased bone fragility and easy fracture, and its clinical manifestations are weakness, pain in the lower back or limbs, spinal deformity and even fracture. Osteoporosis patients can be treated with calcium supplements, such as calcium carbonate, calcium citrate, etc.; drugs that inhibit bone resorption, such as egcalcitonin, salmon calcitonin, etc.; and drugs that inhibit osteoclasts, such as risedronate, alendronate, etc., under the guidance of doctors. In general, osteoporosis patients need to continue to take calcium tablets for about three months, and the time may be extended for patients with more serious conditions. Patients should adjust the dosage according to their own physical condition. After taking this kind of drugs for a period of time, patients also need to go to the hospital for relevant examinations and laboratory tests, and use the results of the tests as a standard as a reference, and adjust the dosage of the drugs under the guidance of the doctor as well as whether to decide to stop taking the drugs, and so on.
