Girls have irregular menstruation after their first period

Generally speaking, after a girl's first menstruation, her second menstruation will not come on time. This is because the various functions of a woman's body are not fully mature at this time, and the endometrium cannot be shed regularly. The body also needs a period of time to adapt to this change in state. Don't worry, as long as you develop good living habits and pay attention to hygiene, there will be no problem.

The on-time arrival of menstruation means that the female body is healthy

Menstruation is an important physiological phenomenon for women, and the onset of menstruation is an important sign that girls are entering puberty. Most girls start having their first period around the age of 13-15, and the first menstrual period is called menarche.

The early or late onset of menarche is related to factors such as genetics, nutrition and climate. Normal menstruation occurs every 28-30 days, ends every 3-7 days, and the menstrual volume is about 30-80ml. For most girls, their menstrual cycles are often irregular within 2-3 years after menarche.

Why do adolescent girls have irregular and irregular menstruation? Experts say that the onset of menstruation in teenage girls indicates that their ovaries are maturing but not yet fully developed, so their ovarian function is often not sound.

The reason why women of childbearing age with fully developed ovaries can have normal menstrual cycles is entirely because the ovaries can ovulate, form a corpus luteum and produce progesterone, which causes the secretion changes of the endometrium on the basis of proliferation. The life span of the corpus luteum is only about 14 days. If conception does not occur, it will degenerate and atrophy about 14 days after ovulation, and will no longer secrete estrogen and progesterone, causing the endometrium to completely fall off, thus onset of menstruation. So some people jokingly call the corpus luteum that produces progesterone the "timer" of menstruation.

About 72 hours after the onset of menstruation, a new batch of follicles begins to develop and produce estrogen, causing the endometrium to proliferate and gradually cover the wound surface of the uterine cavity, and the menstruation gradually stops.

The ovaries of adolescent girls are not fully developed and cannot ovulate, so there is no progesterone produced by the corpus luteum to regulate the menstrual cycle. The follicles in the ovaries develop one batch after another. Before the previous batch of follicles has atrophied, the next batch has already begun to develop. The fluctuation of estrogen levels produced by batches of follicles will cause part of the endometrium to shed and bleed, which is the "menstruation" of adolescent girls.

Because the ovaries do not ovulate and there is no progesterone, the endometrium can neither shed regularly nor be completely and thoroughly shed at once. Instead, part of it sheds today, and part of it sheds tomorrow. By the time the back endometrium sheds, a new endometrium has grown where the front endometrium shed. In this way, the endometrium grows and sheds at the same time, and uterine bleeding continues and is often difficult to stop on its own. The clinical manifestations are menstruation every 40-50 days, and the menstrual period is very long. After about 2-3 years, the ovaries are fully developed and normal ovulation occurs, and menstruation will become normal.

Adolescent girls are in a stage of rapid physical and reproductive organ development, so they should strengthen their nutrition and supplement with foods rich in protein, vitamins, iron, calcium, etc. People with anemia should also be given iron supplements to correct anemia, improve their overall condition, arrange rest time reasonably, engage in appropriate physical exercise, and pay attention to the combination of work and rest.

In addition, you should also pay attention to menstrual hygiene. It is not advisable to engage in strenuous exercise during menstruation and avoid eating too cold or spicy foods. People who experience irregular menstruation, prolonged menstruation, excessive menstrual flow, etc., especially those who have developed anemia, should seek medical attention in time to avoid affecting their health. With treatment, a normal menstrual cycle can be established.
