• 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).
  • A condition that is marked by a decrease in bone mass and density, causing bones to become fragile.
  • A disorder characterized by reduced bone mass, with a decrease in cortical thickness and in the number and size of the trabeculae of cancellous bone (but normal chemical composition), resulting in increased fracture incidence.
  • 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.
  • Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.risk factors include
    • getting older
    • being small and thin
    • having a family history of osteoporosis
    • taking certain medicines
    • being a white or asian woman
    • having osteopenia, which is low bone density
    osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health. To keep bones strong, eat a diet rich in calcium and vitamin d, exercise and do not smoke. If needed, medicines can also help. nih: national institute of arthritis and musculoskeletal and skin diseases
  • Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (osteoporosis, postmenopausal) and age-related or senile osteoporosis.
