(HealthDay News) -- Osteoporosis occurs when bone density decreases and bones begin to thin. Often associated with natural aging, this happens because either insufficient new bone is produced, and/or too much existing bone is reabsorbed by the body.

Treating osteoporosis typically focuses on preventing fractures and additional bone loss, as well as easing symptoms of pain and discomfort. According to the U.S. National Library of Medicine, the most common forms of treatment for osteoporosis include:

• Prescription drug treatments, including bisphosphonates, raloxifene and calcitonin.
• Supplements of calcium and vitamin D.
• Regular exercise, including weight-bearing, resistance and balancing exercises. Walking, stationary bike riding, and other low-impact activities with minimal risk of falling also are recommended.
• Quitting smoking and alcohol.
• Eating a diet rich in dairy products such as low-fat milk, yogurt and cheese; salmon, sardines and tofu; and leafy green vegetables such as spinach and greens.
