What is the reason for delayed menstruation in girls?

I believe that many girls will encounter delayed menstruation in their daily lives. The reasons for delayed menstruation in girls are actually quite complicated. Delayed menstruation in girls may be caused by physiological factors or by some drugs. So let’s take a look at what is going on with delayed menstruation in girls?

A girl’s body fat must account for at least 17% of her body weight before she can have her first menstruation, and her body fat must reach at least 22% of her body weight to maintain a normal menstrual cycle. Excessive dieting will cause a large amount of fat and protein in the body to be consumed due to insufficient energy intake, resulting in estrogen synthesis disorders and obvious estrogen deficiency, affecting menstruation, or even causing scanty menstruation or amenorrhea. Therefore, women who pursue a slim figure must not diet blindly.

According to research, women who are exposed to cold during menstruation will experience excessive contraction of blood vessels in the pelvis, which can cause oligomenorrhea or even amenorrhea. Therefore, women should have a regular daily life, avoid excessive fatigue, and especially keep away from cold and damp during menstruation. Abnormal emotions, long-term mental depression, sulking, or severe mental stimulation and psychological trauma can all lead to menstrual disorders or dysmenorrhea or amenorrhea. This is because menstruation is caused by the stimulation of the endometrium by hormones secreted by the ovaries, and the hormones secreted by the ovaries are controlled by the release of hormones from the pituitary gland and hypothalamus. Therefore, any abnormality in the function of the ovaries, pituitary gland, or hypothalamus will affect menstruation.

If menstruation is delayed only 1-2 times occasionally and there are no other accompanying symptoms, it does not fall into the category of menstrual disorders. When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. The absence of ovulation after menopause can also lead to problems such as osteoporosis and endometrial hyperplasia, which must be taken seriously. You should go to the hospital immediately for a comprehensive examination.

The above introduces to you in detail some of the reasons for delayed menstruation in girls. You can make a preliminary judgment based on your specific physical condition. However, if delayed menstruation occurs frequently in girls, it is better to go to the hospital for a detailed examination. At the same time, actively adjust your work and rest routine to allow the endocrine system to function normally.
