What is the normal value of bone density

If the bone density is low, osteoporosis and fractures are likely to occur, so it is necessary to understand the normal value of bone density. If it is lower than the normal value, then some medications or dietary methods are needed to increase the bone density.

1. Bone density is an important indicator of bone quality, reflecting the degree of osteoporosis and an important basis for predicting the risk of fractures. Due to the continuous improvement of measurement samples and the development of advanced software, this method can be used in different parts and the measurement accuracy is significantly improved. In addition to diagnosing osteoporosis, it can also be used for clinical efficacy observation and epidemiological surveys, and has significant advantages in predicting osteoporotic fractures.

2. Bone density is the full name of bone mineral density, which is an important indicator of bone strength. It is expressed in grams per square centimeter and is an absolute value. When bone density values ​​are used clinically, the T value is usually used to determine whether the bone density is normal because the absolute values ​​of different bone density detectors are different. The T value is a relative value, and the normal reference value is between -1 and +1. When the T value is lower than -2.5, it is abnormal.

3. Drugs and diets to improve bone density:

1. Calcium supplement: If calcium absorption is normal, 1.00g-1.50g per day is sufficient. Among various calcium supplements, calcium carbonate is the most commonly used. For people over 65 years old, take 0.75g to 2.5g per day. For those who have many side effects from using estrogen and may develop endometrial cancer, giving them large doses of calcium can have the same effect as using estrogen. Patients with kidney stones cannot consume large amounts of calcium.

2. Vitamin D and its active products: In the past, it was believed that elderly osteoporosis patients were often accompanied by vitamin D deficiency, so it was advocated to give more vitamin D. In fact, except for those with osteomalacia (generally speaking, only children are prone to osteomalacia, such as rickets), intestinal calcium absorption disorders and reduced production of vitamin D metabolites, there is generally no need to supplement large amounts of vitamin D. Those who have the above three conditions can be given vitamin D at the same time.

3. Calcitonin: Calcitonin can reduce bone absorption, reduce calcium in the blood circulation, and increase the calcium content in bones. Since calcitonin can lower blood calcium, calcium should be supplemented when using calcitonin to play a role in treating osteoporosis.

4. Phosphates: Phosphates have been used to treat osteoporosis in recent years. Phosphates can promote bone formation, inhibit the destruction of bone cells, and can be used for a long time.
