Osteoporosis or thinning of bone results in decreased strength of bone. Though it does not cause any symptoms, it predisposes an individual to fractures especially of the wrist (Colle’s fracture), backbone (compression fracture of vertebra) and hip (fracture neck of femur) even with minor trauma. Thus, early detection of the condition using screening methods and early treatment helps to avoid fractures and its associated morbidity to the patients.
Worldwide, the risk of suffering from osteoporotic fractures is 30-50% in women and 15 to 30% in men. In India, 1 out of every 3 women and 1 out of every 8 men suffer from osteoporosis.
Thus, women are more prone to developing osteoporosis. Estrogens have a protective effect on bones; thus lack of estrogens during menopause plays an important role in the development of osteoporosis.Other factors that increase a person’s risk for developing osteoporotic fractures include:

Prior fracture in the individual or his/her close relatives

Low body weight, thin stature or poor health

Older age

Cigarette smoking or Alcoholism

Corticosteroid use for more than 3 months

Estrogen deficiency at an early age due to conditions like early menopause

Dementia

Impaired eyesight

Recent falls

Low calcium intake

Hyperthyroidism

Rheumatoid arthritis

Oral contraceptives

Decreased physical activity
