Bone trabeculae are thick and sparse as the result of imaging report, i.e. osteoporosis, the cause may be related to postmenopausal osteoporosis, senile osteoporosis, idiopathic osteoporosis and other reasons, which should be analyzed according to the actual situation. 1. Postmenopausal osteoporosis: After menopause, women’s sex hormone levels can be affected. If the body’s estrogen secretion decreases, it will affect the metabolism of bone, leading to abnormally active osteoclasts, which in turn will be broken down and absorbed, resulting in a decrease in the amount of bone and loss of bone, which will lead to an increase in the empty space of the bones and the emergence of osteoporosis. 2. Senile osteoporosis: With the gradual increase of age, the aging of human cells will be accelerated, which will affect the absorption of nutrients and the decline of various functional organs, resulting in the lack of vitamin D in the body, affecting the absorption of calcium, which will lead to the decline of bone mass and bone quality, resulting in osteoporosis. 3. Idiopathic osteoporosis: Idiopathic osteoporosis may be related to abnormal regulation of bone metabolism or exuberant growth hormone during puberty, which will lead to an increase in bone mass, as well as a disruption of the balance between bone formation and absorption, and an abnormal metabolism of calcium ions, resulting in idiopathic osteoporosis. After discovering that the bone trabeculae are thick and sparse, it is necessary to go to the hospital or orthopedic specialist hospital for diagnosis and treatment in time, so as to avoid delaying the condition and affecting the health of the body.
