Children, particularly those entering and passing through puberty, should participate in impact exercise or sports (mainly field and court sports). Men and women throughout life should participate in exercise, particularly weight-bearing exercises such as brisk walking, running or dancing. Bisphosphonates (Didrocal, Fosamax and Actonel) and raloxifene (Evista) are first choice therapies for individuals without menopausal (vasomotor) symptoms. Hormone Replacement Therapy (HRT) is no longer the "gold standard" for treatment of osteoporosis. Alternative treatments such as ipriflavone and vitamin K are not recommended for the treatment of postmenopausal women with osteoporosis. In addition, these therapies are not recommended in men or premenopausal women. However, ipriflavone may be considered as a second-line preventive therapy in postmenopausal women.[/quote] for more info, [url=http://www.osteoporosis.ca/english/News/GuidelinesNewsRelease/]click here[/url] This is [url=http://www.sign.ac.uk/guidelines/fulltext/71/section6.html]SIGN guidelines[/url]
