566 Final Exam Study Guide Week 5 Prevention of osteoporosis with hormone replacement therapy (p. 433) Hormone therapy (HT) reduces postmenopausal bone loss & thereby decreases the risk for osteoporosis & related fractures. Unfortunately, when HT is stopped, bone mass rapidly decreases by approximately 12%. Hence to maintain bone health, HT must continue lifelong. As a result, the risk for harm is increased. Accordingly, alternative treatments are preferred. Effective alternatives to HT include...
