Physical activity is very important in this condition. Studies show activity must be ongoing. The old saying "use it or lose it" is very true with bone density. So congratulations, you're on the way to better bone health!

In adults physical activity helps maintain bone mass. Regular exercise and physical activity prevents further bone loss. It's not proven yet that it builds up bone already lost. Studies show high intensity or high resistance exercise may help bone density increase, but most older adults can't exercise at this level.

Many doctors combine exercise with a new bone-building drug. The drug is most often a bisphosphonate called Fosamax. Under this treatment program, bone mineral density can be improved. Turnover of bone cells is a fairly slow process. It takes three to four months for one full cycle of bone resorption, growth, and mineralization. It's a minimum of six to eight months to show measurable changes in the bone.

Your doctor will tell you when it's best to be retested. In the meantime, stick with your exercise program faithfully and keep it up for the rest of your life. You'll benefit not only your bones, but the rest of you as well.
