Osteoporosis
- loss of bone mass and strength due to nutritional, metabolic, or other factors, usually resulting in deformity or fracture; a major public health problem of the elderly, especially women.
- (OSS-tee-oh-pa-ROW-sis) A condition that is characterized by a decrease in bone mass and density, causing bones to become fragile.
- A condition of reduced bone mass, with decreased cortical thickness and a decrease in the number and size of the trabeculae of cancellous bone (but normal chemical composition), resulting in increased fracture incidence. Osteoporosis is classified as primary (Type 1, postmenopausal osteoporosis; Type 2, age-associated osteoporosis; and idiopathic, which can affect juveniles, premenopausal women, and middle-aged men) and secondary osteoporosis (which results from an identifiable cause of bone mass loss).

Osteoporosis unspecified
- loss of bone mass and strength due to nutritional, metabolic, or other factors, usually resulting in deformity or fracture; a major public health problem of the elderly, especially women.
