Experts believe that osteoporosis is a largely preventable disease. But prevention must be started early. Receiving enough calcium as a child and teenager can dramatically cut your risks of developing osteoporosis later in life. As an adult, eating a good diet, getting enough calcium and vitamin D, exercising, and avoiding lifestyle habits such as smoking and excessive drinking, can help prevent osteoporosis. To learn about osteoporosis prevention techniques you should talk to your doctor.
