The normal value for bone density in a 46 year old female is T > -1 g/cm3. If T > -1 g/cm3 is currently being monitored, then it is considered healthy bone mass, indicating that osteoporosis is not currently occurring, and there is generally no adverse reaction at this time, and no special treatment is required. If the T value is lower than -1 to 2.5 grams per cubic centimeter, then we should be alerted to the fact that the bone mass is gradually decreasing, related to malnutrition. If you do not replenish the nutrients and energy needed by your body, the loss of calcium may lead to a decrease in T-value. A T-value in the range of less than -2.50 grams per cubic centimeter should be on high alert for the possible presence of osteoporosis, when the patient will often experience symptoms such as aching bones and body weakness. In addition to the measurement of bone mineral density to determine the presence of osteoporosis, women aged 46 years also need to be analyzed in conjunction with X-ray absorptiometry as well as quantitative CT examination. When osteoporosis and other diseases occur, seek timely medical treatment to avoid the development of the disease.
