The onset of menstruation is a sure sign that the girl has turned into a girl and, theoretically, can give birth. The onset of the first menstruation varies depending on the region, race and hereditary factors. In
how many years do girls have normal periods? We will try to answer below and this question.
The fact of how many years in girls begins menstruation is due primarily to genetics. If mom and grandmother had “red days of the calendar” at age 12, then the girl should expect the onset of menstruation around this time. But still, in most cases, a girl turns into a girl between 11 and 13 years old, that is, 2-2.5 years after the mammary glands began to grow . If menstruation began at 9 years old and earlier, then this is considered an early menstruation. If a girl’s malaise did not visit the girl after 15 years, then you should consult an endocrinologist. Violations can be caused by malfunctions of the endocrine system or malfunctions of the hormonal background.
The age at which the periods begin for girls depends on a number of factors, including not only heredity, but also the level of physical development, the illnesses that the girl suffered from in her early childhood, nutrition quality, general emotional background, place of residence and origin. Menstruation in girls begins earlier, if from childhood they overtake peers in development. And vice versa, if the development is somewhat slowed down, then the "red days of the calendar" may come later. If during puberty and childhood the girl did not receive enough
amount of vitamins and ate badly, then menstruation will come with a delay. Therefore, in order to find out exactly what time girls start their periods, you need to take into account many factors and understand that this process is purely individual. For example, girls who live in southern countries turn into a girl earlier than their peers living in northern regions. Meanwhile, in our latitudes, menstruation occurs in girls in winter. It is believed that in the summer, in the conditions of heat and not very high-calorie nutrition, the body pushes the beginning of the first menstruation to winter, since more calories are consumed in winter.
The influence of past diseases on the menstrual cycle
On how many years the girl begins menstruation, and the past diseases also affect. For example, the
reproductive system is negatively affected not only by meningitis and encephalitis, but also by common colds, SARS, tonsillitis. Of the chronic diseases, diabetes, heart defects, and bronchial asthma have the greatest impact. All this slows down the development, leading to the fact that menstruation occurs in the girl later.
How to prepare the girl for the beginning of menstruation, and what day is considered the first day of the cycle?
First you need to explain that everything is normal and that menstruation is not a disease, but a natural state of the body. Many people cannot understand for a long time when the menstrual cycle begins , mistakenly believing that the first day of the new cycle is the day the menstruation ends. In fact, the first day of the cycle always coincides with the first day of menstruation. Regardless of the age at which menstruation begins, it is necessary to explain what changes occur in the body, as well as what consequences they entail.
