Severe osteoporosis can be properly exercised. Osteoporosis is a metabolic disease characterized by a decrease in bone mass. Exercise can strengthen bones, increase bone weight and help maintain bone mass and reduce bone loss, as well as exercise muscles, which are strong and healthy and can also protect bones. For people with severe osteoporosis, they can choose some aerobic exercises, such as swimming, dancing, walking, etc., which can exercise the lower limbs to reduce bone loss, but they should pay attention to the degree and manner of exercise, and should not exercise strenuously, or wear orthopedic devices to prevent the exercise from causing spinal deformation or vertebral fracture. If osteoporosis is diagnosed, it is recommended to go to the hospital in time for standardized treatment under the guidance of the doctor.
