Osteoporosis is a condition wherein your bones become weak and fragile. It is predominantly a disease of the elderly and is mostly noticed in women after menopause. Estrogen, the female sex hormone, has a protective effect on the bones. After menopause there is a decrease in estrogen thereby leading to weakening of the bones. All postmenopausal women more than 50 years, especially if they present with a fracture, should be evaluated for osteoporosis.
