A few years ago, we saw a very strange thing in the news. A little girl in India started menstruating just after she was born. This situation was incredible and attracted the attention of the local police. In fact, if a girl has vaginal bleeding in childhood, it is a very serious matter and she needs to go to the hospital for diagnosis in time to avoid illegal incidents. So, how should we view this matter? 1. Duration Generally, after 4 to 5 days, most of the endometrium is shed. Under the action of female hormones, a new layer of endometrium grows and gradually thickens. At this time, the menstruation is over. 2. Age of onset Menarche usually occurs during puberty, usually between the ages of 11 and 19. Very rarely, menstruation occurs before the age of 10 or after the age of 19. The early or late menarche is generally believed to be closely related to genetics. If the mother has her first menstruation early, her daughter will also have her first menstruation early; if the mother has her first menstruation late, her daughter may also have her first menstruation late. But this is not absolute, it will also be affected by other factors. The early or late menarche is also related to living in cities or rural areas. The age of menarche in urban girls is earlier than that in rural girls. The reason for this is that it is generally believed that among people with a higher standard of living, good nutrition and health, girls not only grow faster physically, but also have their first menstruation earlier. Some people also believe that because the urban lifestyle increases contact between the sexes, some have more opportunities to come into contact with sexual knowledge, which in turn causes the nervous system to regulate the endocrine glands, causing the sex-related endocrine system to become active prematurely, thus bringing forward menarche. 3. Symptoms At menarche, the ovaries weigh only 40% of their mature weight. The ovaries continue to develop grow up. 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 heaviest bleeding occurs on the second and third days. During menstruation, due to pelvic congestion, you may sometimes experience dizziness, craving for popsicles, mild abdominal pain, back pain, breast swelling, and poor appetite. These are all normal phenomena. |
