At what age do girls usually get their first menstruation?

Menstruation is a physiological phenomenon that only occurs in women. It can also maintain the health and balance of female friends. In modern daily life, female friends may not pay so much attention to menstruation, because there are many problems arising from menstruation, many of which are some basic knowledge about menstruation, such as at what age is it normal for girls to have menstruation? Let’s take a look at this kind of problem together today.

At what age is it normal for girls to have their periods?

Generally speaking, girls' menstruation age is between 12 and 16 years old, with an average of 14 years old. Because every girl's physical fitness is different, the age of menstruation cannot be exactly the same. It is normal as long as it comes at this age. If it comes too early or too late, it will affect the growth and development of the child.

Menstruation comes too early

Due to incorrect lifestyles, more and more children are suffering from precocious puberty, and the obvious manifestation of precocious puberty in girls is early menstruation, some even come at the age of 8 or 9, which is very bad. Early menstruation will not cause children to stagnate, but precocious puberty will cause the epiphyseal line to close early, causing the child's height to lag far behind that of people of the same age.

Parents should urge their children to develop a good lifestyle, avoid staying up late, eating fried foods frequently, etc., otherwise it will be too late to regret when they develop precocious puberty!

Menstruation is too late

For girls, if they have their first menstrual period at the age of 20, it is too late. It is probably caused by delayed language development. If menstruation has not come during puberty, the growth and development of each organ of the body is not very good, which may affect the psychological state of girls. Therefore, parents should pay more attention to it and take their children for examination in time to avoid affecting the growth and development of their children.

What are the possible disadvantages of drinking tea during menstruation for women?

1. Drinking tea during menstruation can easily increase the mobility of iron molecules. In addition to the body's normal iron outflow, women also lose an additional 18-21 mg of iron during each menstrual period. Tea contains 50% tannic acid, which will combine with the iron molecules in food to form precipitation, hindering the gastrointestinal mucosa's absorption of iron molecules. Therefore, drinking tea during menstruation will undoubtedly increase the flow of iron.

2. Drinking tea during menstruation can easily aggravate the symptoms of constipation. Due to the metabolism of progesterone growth hormone, some women may experience constipation during their menstrual period. Tea contains more tannic acid, which has astringent effect and can slow down intestinal peristalsis, causing stool to stay in the intestines.

3. Drinking tea during menstruation may aggravate menstrual reactions. During menstruation, women will always experience varying degrees of anxiety, headaches, breast pain and other reactions due to changes in neuroendocrine regulation. However, substances such as caffeine and theatrical aminophylline in tea have the effect of stimulating people, which will aggravate physiological reactions such as anxiety, headache, and backache.
