How old is a girl when she starts menstruation

When a person is just born, his bones are very fragile, but as he grows, the body absorbs calcium and the bones will gradually mature. Moreover, the best way to measure a person's age is to measure his bone age, so the size of bone age also represents a person's physical development level. Women generally start menstruating when they reach a certain age. So at what bone age will a woman start menstruating?

The time period of menarche for girls varies. Generally speaking, it is between the ages of 14 and 16. However, with the improvement of people's material living standards, the menarche of girls is gradually being advanced, and some girls also have their menarche between the ages of 10 and 12. This is related to genetic factors, and at the same time, it is also related to living standards and nutritional components.

After a girl's menarche, her height growth will gradually slow down overall, but there will be individual differences, and some will continue to grow rapidly. About a year after a girl's menarche, her height growth will gradually slow down. The average height increase is generally 5 to 7 cm, but there are a few girls who grow another ten centimeters after their menarche. In another case, some girls only grow 2 to 3 cm in height after their menarche. People often use a girl's menarche to judge her future height, but this is not a completely accurate prediction of a girl's height. The most critical factor is the girl's bone age. The girl's growth potential can only be determined based on her bone age.

How tall a girl will grow after her menarche depends most on her bone age, which is used to determine her growth potential. This is influenced by family factors, social environment factors, genetic factors, living standards, and exercise factors. Some girls' bone age is still relatively young after their menarche, so they may be able to grow a few centimeters through exercise. Of course, the factors that determine a girl's height mainly come from both parents. If the parents are taller than others, then the average height of her children will also increase.

So what should girls pay attention to during their growth?

Note 1: The nutrients should be balanced and you should consume more high-quality animal protein. For example, meat, fish, and eggs are all rich in protein.

Note 2: Eat less snacks and sweets, because sweets will affect the body's absorption of calcium, thus affecting the body's development. Note three: exercise more, participate in more outdoor sports and aerobic exercises. Depending on the size of a girl's bone age, exercise can increase her height.

The third thing to note is that you must eat breakfast, no matter how much you weigh. Don't stay up late and maintain good living habits and eating habits. In this special process, pay attention to nutrition and exercise. Your height can be predicted by the size of your bone age.
