Abstract
Adequate amount of thyroid hormone is an essential requirement for normal development and maturity of bones in the early life as well as for the maintenance of the skeletal system (bone remodeling). Osteoporosis, one of the most common metabolic bone disorders, is strongly associated with hyperthyroidism (endogenous and exogenous), whereas association of the same disease with hypothyroidism is not quite established. Most of the data describing the association between osteoporosis and hyperthyroidism are collected among elderly population (especially postmenopausal women), and only a few studies in literature researched into osteoporosis and hyperthyroidism in <50 years of age; hence further studies are required in the younger population (including premenopausal women and younger males).
