Bones become weak and brittle. The body constantly absorbs and replaces bone tissue. With osteoporosis, new bone creation doesn’t keep up with old bone removal. Can lead to deformity and fractures. Osteoporosis affects men and women of all races. But white and Asian women, especially older women who are past menopause, are at highest risk. Medications, healthy diet and weight-bearing exercise can help prevent bone loss or strengthen already weak bones.
