How to tell if your period is normal

　　What is normal menstruation?

　　generally female Menstruation should occur once a month. The so-called normal menstrual cycle refers to menstruation once every 3 to 5 weeks (usually 28 to 30 days), each menstrual period lasts for 3 to 7 days, and the monthly menstrual volume is about 50 to 80 ml. On the first day of menstruation, the amount is small, on the 2nd and 3rd days it is large, and after the 4th day, the amount decreases and gradually becomes clear. The color of menstruation is dark red or light red on the first day of menstruation, then gradually turns red or dark red, and then becomes light red or dull and clean. Menstruation is liquid, neither thin nor thick. There are no blood clots, but there may be small fragments. Menstruation has no special odor except the smell of blood. The main component of menstruation is blood, among others Uterus Endometrial fragments, cervical mucus, vaginal exfoliated epithelial cells, vaginal bacilli, etc. There are generally no special symptoms during menstrual cramps, and a few women may have slight lower abdominal and breast pain. distended pain , lumbosacral swelling, mental fatigue, upset, frequent urination and other symptoms, but it does not affect work and study, these are normal physiological phenomena.

　　Several special phenomena

　　“"Combining the moon" is a special manifestation of menstrual physiology. There are also other special phenomena recorded in traditional Chinese medicine literature, such as quarterly menstruation: when the body is disease-free, menstruation occurs once every three months, also known as menstruation. Avoiding the New Year: It means that the body is disease-free and menstruation occurs once a year. Xia Xia: There is no illness in the body, but menstruation stops every summer. Dark Meridian: It means that the body is disease-free and will not have menstruation for life but can conceive. These are special phenomena and should not be treated as menstrual diseases. As long as they meet the above-mentioned normal menstrual period, quantity, color and quality, and there are no obvious special symptoms, they are all normal. Patients with these special phenomena can still conceive and have children.

　　How menstruation occurs

　　People may have questions, how should these special phenomena be understood? This requires an explanation of how menstruation occurs first. The onset of menstruation is the process of shedding the endometrium. The endometrium is affected by hormones secreted by the ovaries and undergoes cyclic changes. There are follicles in the ovary. The follicles will grow from small to large, gradually grow and develop into mature follicles, and then ovulate. During this process, the ovaries secrete estrogen, and after ovulation, estrogen and progesterone are secreted. There are glands, stroma, blood vessels, lymphatic vessels, etc. in the endometrium. The endometrium is affected by estrogen secreted by the ovary and undergoes proliferative changes. It is characterized by an increase in the number of glands in the endometrium, an increase in the interstitium, tissue edema, and elongation of blood vessels. On this basis, affected by the progesterone secreted by the ovary, there are changes in the endometrium during the secretory phase. At this time, the glands further increase, bend, and enlarge, secretory granules appear, the interstitium is loose and edema, the blood vessels further increase in curved spirals, and the endometrium thickens. The endometrium in the secretory phase is rich in nutrients, preparing conditions for the planting and development of fertilized eggs. If there is no pregnancy, the ovaries will no longer secrete estrogen and progesterone due to follicle degeneration. The endometrium will not be supported by estrogen and progesterone. The glands in the endometrium will shrink and become thinner, interstitial edema will disappear, blood vessels will be compressed, and blood flow will not be smooth. The endometrium will not get blood supply, spasm, ischemia, necrosis will occur, and the endometrium will fall off and menstruation will occur.

　　To sum up, menstruation is a complex process. “Synopsis is caused by the delayed development of follicles in the ovaries, delayed and insufficient hormones secreted by the ovaries, and delayed changes in the endometrium. The basic principle of summer break is the same as that of the same month. In summer, the ovaries seem to be dormant and their functions are inactive. The hormones they secrete are also delayed and insufficient, and the changes in the endometrium are delayed. As for dark menstruation, we have already explained the mechanism of menstruation. The structure of the endometrium is complex and complete. Some people have incomplete endometrium development, similar to some animals in the order of primates. Although they do not menstruate, they are fertile.
