Introduction
Bone density is generally expressed as a T-score, with normal values ranging between -1 and 1. If the T-score falls between -1 and -2.5, it indicates low bone density and the presence of osteoporosis; in such cases, medications such as calcium gluconate tablets and vitamin D3 should be taken orally under medical supervision. In particular, middle-aged and elderly individuals, postmenopausal women, and those with a history of pathological fractures should undergo regular bone density testing.
A bone density T-score of -1.3 indicates mild osteoporosis. When the bone density value falls between -1 and -2.5, it is diagnosed as low bone mass (osteopenia), which represents the early stage of osteoporosis. The details are as follows:
Bone density is typically expressed as a T-score, with normal values ranging from -1 to 1. If the T-score is between -1 and -2.5, this indicates reduced bone density and the presence of osteopenia, an early form of osteoporosis. At this stage, patients should take calcium gluconate tablets, vitamin D3, and other medications under medical supervision. In particular, middle-aged and elderly individuals, postmenopausal women, and those with a history of pathological fractures should undergo regular bone density testing to monitor changes.
Bone density reflects a person's physical condition and biological age. Early detection of osteoporosis helps predict fracture risk. Since bone density indicates skeletal health, abnormally low levels may result from calcium deficiency or underlying bone disease. A negative T-score often suggests insufficient calcium intake or excessive bone loss.
For individuals with low bone density, it is recommended to consume more calcium-rich foods such as beef, lamb, dragon fruit, and bananas. In addition to dietary adjustments, engaging in daily moderate exercise—such as jogging, tai chi, or swimming—can help improve overall immunity and support bone health.
