Athletes prone to amenorrhea

　　A large number of analysis and observations have shown that during strict and serious training of athletes, many people's menstruation will become irregular, and some will even stop completely. For example, the proportion of abnormal menstruation accounts for about 20% of long-distance runners and can be as high as 50% to 75% of ballet practitioners. Especially for young girls, a greater amount of exercise exercise At this time, a larger proportion of people have abnormal menstruation, which are mostly manifested by delayed menarche, irregular cycles, and secondary menstrual cramps. amenorrhea wait. And the greater the amount of exercise, the later the age of menarche. For example, 67% of female athletes aged 17 to 23 in a sports school have amenorrhea. ； And those who did not participate in sports at the school female , only 13% have amenorrhea. Although the reasons are not yet fully understood, the following factors are worth noting.

　　1. Exercise, like weight loss, will lead to the reduction of body fat. Women need a minimum amount of fat to maintain menstruation. If the body weight is lower than 10% to 15% of the normal body weight, or the proportion of body fat is too low, less than 17% of the body weight, the body lacks the fat to produce estrogen raw materials, which will affect the normal level of estrogen, thus interfering with the formation and cycle of normal menstruation. When fat mass is too low, it may also cause the body to convert normal estrogen into another type of inactive estrogen. This inactive estrogen cannot send messages to the brain, so menstrual function stops. Rigorous exercise training not only causes weight loss, but also puts a lot of stress on the body. Some scholars believe that the body shuts down menstruation when it is stressed to avoid pregnancy in a fearful or chaotic environment.

　　2. Exercise increases the content of endorphins in the brain, which is a sedative substance naturally produced in the body. It’s euphoric at the same time. Interestingly, endorphins have a stronger euphoric effect on the brain than pure morphine. This may be why people feel a sense of relaxation and happiness after intense exercise, including the "pleasure" that Ms. Bai experienced after running. However, high concentrations of endorphins will affect the normal hormone operation of the brain and the menstrual cycle. These factors may lead to a decrease in estrogen, cessation of ovulation and cessation of menstruation.

　　3. Without menstruation, there is generally no danger. However, if estrogen is too low for more than 6 months, it may cause calcium loss in the bones, leading to osteoporosis. In the long run, fractures, scoliosis, etc. may occur, and even the original constitution may healthy Women are not immune either. One-third of female athletes at a certain sports school had fractures, while only 6% of non-athletes had fractures.

　　4. For most women, once factors such as excessive exercise, weight loss, or stress stop, menstruation will gradually return to normal after a few months. If detected and corrected early, osteoporosis may be saved after menstruation returns to normal. If menstruation has not returned to normal after a considerable period of time, periodic therapy can be performed under the guidance of a doctor, which can achieve good results. In addition, traditional Chinese medicine Menstrual disorders It also has unique curative effects. Thankfully, once normal menstrual cycles resume, these women's chances of getting pregnant are barely affected at all. >>>>. 12A classic dietary remedy for dysmenorrhea
