Osteoporosis is a condition characterized by progressive loss of bone calcium, thinning and weakening of bone tissue and increased vulnerability to fractures. Osteoporosis may result from disease, dietary or hormonal deficiency, or advanced age. Regular exercise, calcium and vitamin D supplements, and prescription medications can reduce and even reverse loss of bone calcium.
