What is the normal range of BMD? Is the higher the number, the better?

summary

Recently, my legs are always pumping. My friend suspects that it is the reason for the decrease of bone mineral density. I can go to the hospital for a bone mineral density examination to see if it is normal. I heard about the concept of bone mineral density examination for the first time. I don't know what the normal range of bone mineral density is? Is the higher the number, the better?

What is the normal range of BMD? Is the higher the number, the better?

First, individual bone mineral density measurement is often compared with the same age, the same sex control group and the same sex young people control group. These values are either expressed as percentages or as standard deviations and are called z-scores or T-scores, i.e. z-values or t-values.

Second: bone mineral density refers to the mineral density of bone, which is an important index for the diagnosis of osteoporosis, guidance of reasonable calcium or drug efficacy evaluation, evaluation of bone hardness and prediction of fracture risk coefficient.

Third: in clinical practice, t value is usually used to judge whether the BMD is normal or not. The reference range of normal value is between - 1 and + 1; when t value is lower than - 2. Osteoporosis occurred at 5. The normal value of BMD is not a specific value, as long as the BMD value is within a given range, it is a normal value.

Fourth: bone mineral density is a test to determine whether the baby is lack of calcium. Your baby's result indicates that there is a lack of calcium. You can appropriately supplement calcium agents, vitamin D agents, such as calcium lactate, calcium carbonate and other calcium agents, vitamin D or icosin to promote the absorption of calcium.

Fifth: normal: BMD is within 1 SD of the average value of young people (+ 1 ~ - 1 SD). Low BMD: BMD is 1-2 lower than the average value of young people. 5SD(-1～-2。 5SD)。 Osteoporosis: BMD is lower than the average of 2 in young people. 5SD (below - 2. 5SD)。

Sixth: bone mineral density decreased in normal range. The reference range of standard value is - 1 to + 1; when t value is lower than - 2. Osteoporosis occurred at 5. Given your age, - 1. 9. Tonifying the kidney is not an appropriate adjustment of diet.

matters needing attention

Osteoporosis has few self-conscious symptoms and is not easy to be detected in the early stage. Therefore, it is suggested that every person should have a bone mineral density screening every year to understand their own bone status.
