Osteoporosis, or osteoporosis, is a metabolic bone disorder characterized by a decrease in the amount of bone tissue per unit volume. Long-term vitamin and calcium malabsorption as well as deficiency of certain micronutrients after gastrectomy leads to osteoporosis, causing pain, fractures and other symptoms. Its common treatments include medication. Drugs used to treat the development of osteoporosis include vitamin D and active vitamin D to promote calcium absorption, diphosphonates such as alendronate to inhibit osteoclasts, selective estrogen receptor modulators such as raloxifene to inhibit bone resorption by exerting an estrogen-like or antagonistic effect in certain organs, and fluoride such as tylosin to increase bone density and promote bone formation. If the symptoms of osteoporosis after gastrectomy are more serious, you should go to the hospital in time, complete the relevant examinations, and carry out the corresponding treatment under the doctor’s diagnosis, and do not blindly apply the drugs on your own. You should not blindly apply medication on your own. You can increase your daily exercise and supplement your body with vitamins and trace elements through a reasonable diet.
