What is the best age for women to have their first menstruation?

Menarche is the first time a woman's endometrium bleeds, which is discharged from the vagina. Generally speaking, the time of menarche is closely related to the individual's physique. Normally, it occurs between 15 and 19 years old, and earlier between 11 and 13 years old. This has a lot to do with the environment or physical nutrition.

Normal age for girls to start menstruation

1. The normal age for girls to have their first period

Girls usually start menstruating at 13-14 years old, but can start as early as 11-12 years old. Based on individual physical differences, most girls are around 12-19 years old, with 15 being the most common age on average.

The early or late menarche is controlled by genetic factors, and nutrition and weight also play an important role. In recent years, the age of menarche has tended to be earlier. It is normal for women to have their first menstruation at the age of 12-15 years, but individual differences may be large. Menstruation can start as early as 9 years old or as late as 18-19 years old if there are no other abnormal conditions.

Generally speaking, a girl's first menstruation is determined according to individual physical differences. Research has found that living standards, nutritional health, and environmental climate are all related to girls’ menarche. Menarche is the most obvious sign of a girl entering puberty and is an important physiological stage for girls.

2. How to predict the age of menarche

2.1. Use height to estimate the age of menarche: During adolescence, measure your height every six months to see which year your height grows fastest. Generally, the first menstrual period occurs in the late part of the year when height growth is the fastest.

2.2. Predicting the age of menarche by weight: Measure weight every six months during adolescence. As puberty develops, weight begins to increase, and menarche usually occurs in the late year of the year when weight increases sharply.
