Osteoporosis after fracture usually improves gradually after the fracture is healed and normal limb activities are resumed, usually more than 3 months, and the specific time of improvement needs to be judged according to the specific situation. Osteoporosis after fracture is mostly caused by the lack of activity of the affected limb after fracture, which affects the absorption of calcium. If the symptoms of the fracture are mild, you can get out of bed and walk in about 3 months, and the osteoporosis symptoms will improve in the process of gradual exercise. If the symptoms of the fracture are severe and you cannot get out of bed and walk for about 3 months, the osteoporosis condition may last for a longer period of time. In addition, some elderly patients, whose bodies have weaker metabolism, have a more difficult time recovering from osteoporosis after a fracture. After the fracture, they may need to be treated by external fixation or surgery, and they need to take calcium tablets and other medications as prescribed by the doctor in time, as well as eat more soy products, milk and other foods with high calcium content to replenish the calcium element needed by the body.
