A bone mineral density of minus 1.6 indicates a mild decrease in bone mass, which is not considered osteoporosis, but suggests an increased risk of developing osteoporosis. Diagnosis of osteoporosis needs to be based on the bone mineral density T-value judgment, T-value of the normal range of -1 ~ 1, if the T-value of -2.5 ~ -1, suggesting a decline in bone mass; if the T-value is lower than -2.5, suggesting that the osteoporosis. Therefore, a bone mineral density of -1.6 is not considered osteoporosis. Through the bone density examination, T value and Z value can be deduced. T value refers to the difference between the bone density of the examined person and the peak bone density of a normal person, which is used to screen for osteoporosis, and Z value is used to reflect the severity of osteoporosis. Z value higher than -2.0 is normal, and if it is lower than -2.0, it suggests that osteoporosis, and the lower the Z value is, the more serious the osteoporosis is. If you have a bone mineral density of minus 1.6, you should take calcium-rich food and exercise appropriately, and it is recommended that you go to the hospital in time for treatment.
