1. Is osteoporosis an inevitable process of a person from youth to old age? It can be said to be a natural manifestation of aging, but this manifestation of aging is not unchangeable. Generally speaking, from the age of 30, various organs of the body will begin to appear a series of degeneration, and bones are no exception, and women occur faster. It is recommended to start paying attention to the prevention of osteoporosis at the age of 30, including diet, exercise and so on. By the age of 40, more than 50 years old and then prevention or treatment, has been too late, too late. 2, that before 30 years old can not worry about osteoporosis, wait until after 30 years old and then start to pay attention to prevention? Before the age of 30, osteoporosis basically does not occur, and the osteoporosis we are talking about here refers to primary osteoporosis. The so-called primary osteoporosis is a phenomenon of natural decline of the body without any special cause. Another condition is secondary osteoporosis, although young may also lead to osteoporosis, such as: (1) hyperthyroidism; (2) long-term use of hormones; (3) long-term heavy alcohol consumption. These patients are likely to develop osteoporosis before the age of 30, so it is even more important to pay attention to prevention. 3, the incidence of osteoporosis in women is 6 to 10 times higher than that in men, why is there such a big difference? Women have a much greater chance of developing osteoporosis than men. The main reason is that: (1) the physiological differences between men and women: after menopause at the age of about 50, the body will undergo a series of metabolic changes due to the reduction of estrogen levels, resulting in an imbalance in bone metabolism, leading to osteoporosis. (2) Men and women in daily life undertake different work situations: men physical labor, outdoor sports than women. It is like saving money in the bank, if you save more money in the bank when you are young, you can take money out of the bank when you are old. This aspect is also one of the reasons for the different incidence of osteoporosis in men and women after old age. 4, some people say that women will lose half of the calcium in their bodies if they have a child, and are prone to osteoporosis and other bone problems, is there any truth to it? This is definitely not true. This has no scientific justification, since ancient times many women may have many small children in their lifetime, if the birth of a child will lose half of the calcium in the body, the birth of two small children calcium is no more? But women who are pregnant should be supplemented with calcium and other nutrients through dairy products, soy products, etc. This is as it should be.
