Factors that affect menarche in little girls

During menstruation, women have poor physical fitness. At this time, women need to pay attention to their diet. Women should choose foods with high nutritional value, which is very helpful for improving the body's immunity and preventing diseases. Women during menstruation cannot choose cold foods, especially ice cream. What are the factors that cause little girls to have their first menstruation?

Factors that cause menarche in little girls:

When a woman reaches puberty, under the influence of the hypothalamus and pituitary hormones, the ovaries produce sex hormones, which can stimulate the development of sexual organs and breasts, and begin to grow armpit hair and pubic hair; at the same time, the egg cells in the follicles in the ovaries gradually mature, and the mature follicles rupture and expel the egg cells out of the ovaries. At this time, the fallopian tube umbrella absorbs the expelled egg into the fallopian tube lumen. After ovulation, the remaining cells in the follicle grow and increase rapidly and become yellow, which is called the "corpus luteum". It secretes progesterone, which prompts the endometrial glands to secrete a nutrient-rich mucus in preparation for receiving the fertilized egg. If the egg is not fertilized, the corpus luteum will atrophy 9 to 10 days after ovulation, the secretion of estrogen and progesterone will decrease, and the endometrium will gradually atrophy, fall off, and bleed, which is the manifestation of menstruation.

As we all know, before puberty, the reproductive organs develop slowly and are in a childish state, and then develop rapidly after entering puberty. The ovaries are very small before the age of 8, develop rapidly between 8 and 10 years old, and then grow rapidly. The uterus also develops rapidly during the age of 10, with the body of the uterus significantly increasing in size and doubling in length. Menstruation is related to cyclical changes in the ovaries and endometrium. Starting from puberty, the eggs in the ovaries gradually develop, mature and are released. At the same time, the ovaries secrete estrogen and progesterone, which promote the thickening of the endometrium and the proliferation of blood vessels, creating conditions for the fertilized egg to develop, mature and implant in the uterus. If the released egg is not fertilized, the secretion of estrogen and progesterone in the ovaries will decrease rapidly, causing necrosis and shedding of endometrial tissue and rupture and bleeding of blood vessels. The shed endometrial fragments along with the blood

Discharge from the vagina is called menstruation. At menarche, the ovaries weigh only 40% of their mature weight. The ovaries continue to develop and grow. Due to the instability of ovarian function and regulation, menstruation may not occur regularly every month within half a year to a year after menarche. After menarche, some women may have their second menstruation after several months, half a year or even a year. This is not a pathological phenomenon and menstruation will occur on time every month in the future. Each menstrual bleeding lasts about 5 days, which is the menstrual period. Generally, the menstrual volume is 10 to 100 ml, with an average of 50 ml. The amount of bleeding is highest on the second and third days. During menstruation, due to pelvic congestion, you may sometimes experience mild abdominal pain, back pain, breast swelling, and poor appetite, which are all normal phenomena.

These are the introductions to the menarche of little girls. After understanding the menarche of little girls, women should not panic when they just start menstruating. At this time, if they don’t understand something, they can consult their parents to avoid harm to their bodies. In addition, if women do not have dysmenorrhea in the early stages, they should also pay attention to their eating habits in the future to avoid dysmenorrhea.
