Osteoporosis fractures are four times more common than strokes. Women in their 50s have an equal chance of experiencing complications of osteoporosis as they do from breast cancer according to orthopedic surgeon and traumatologist Sanjay Rastogi at a recent osteoporosis awareness lecture. Early menopause (before 45 years of age) is the single greatest risk factor for osteoporosis. Other reasons include... poor calcium intake and deficiency of Vitamin D, smoking and alcohol consumption . Explaining the disease, he said: Osteoporosis is a condition in which bone become more porous than average and are prone to fracture. The loss of both calcium and bone matrix leads to decreased bone mineral density (BMD) and increased bone fragility. The disease speeds up in women within 10 years after menopause. This is primarily because the ovaries stop producing the female sex hormone estrogen, which is one of the substances that helps, keep bones strong.
