In fact, men and women are almost equally likely to suffer from hemorrhoids, with the difference not being significant, being around 50%. However, the majority of women who suffer from hemorrhoids, or whose symptoms worsen, are related to pregnancy and childbirth! Therefore, hemorrhoids in women can even be called “mother’s hemorrhoids”! The cause of hemorrhoidal disease in women may be related to the following factors: First, the anal cushion within the venous plexus blood vessel wall with estrogen receptors and mammary gland-like tissues, in the menstrual cycle, with the development of follicles, estrogen secretion gradually rises in the 2 days before ovulation to reach the peak, the high level of estrogen content in the blood can lead to expansion of blood vessels within the anal cushion, congestion, which leads to the anal cushion of the swollen, so the majority of female patients, before menstruation or menstruation hemorrhoidal disease, or symptoms worsened most of the time. Before or during menstruation, hemorrhoidal disease appears to be the most or the most obvious manifestation of hemorrhoidal disease. Second: female hemorrhoids occur in the anterior far more than the posterior and other parts of the body, or can be said, the vast majority of female hemorrhoids are from the anterior (between the anus and vagina) began, the early more than the skin, the later gradually formed the true meaning of hemorrhoidal disease. The reason why they tend to occur here is mostly related to childbirth. The compression of the birth canal by the fetus, especially a large fetus, especially at the end of the birth canal, is very likely to produce local injury, stasis, obstruction of reflux, etc. The longer the labor, the more frequent the birth of hemorrhoids, the incidence of hemorrhoids and the symptoms of hemorrhoids also worsened. The incidence of hemorrhoids in women who are not pregnant is significantly lower than that of pregnant women, both pre-pregnancy hemorrhoids, but most of the symptoms are mild, are due to pregnancy or childbirth to make the symptoms significantly worse. In pregnancy, the female pelvic arterial blood flow than the usual increase of about 25%, the corresponding venous blood reflux will also increase significantly, but because with the increase in pregnancy weeks, the uterus is also in the subsequent significant increase in size, the uterus in non-pregnancy is only about 50g or so, and in full-term, the uterus can be increased to the original 20 times, of course, does not include the weight of the fetus. This significant increase in pelvic contents, can significantly affect the return of the pelvic veins, so that the pelvic veins within the pressure increases, and subsequently affects the hemorrhoidal venous return, the anal cushion within the pressure increases, the lymphatic reflux is also affected, at this time, either raw hemorrhoids, or long hemorrhoids. In addition, pregnancy progesterone, relaxin, not only can be vasodilatation, can also make the tissue relaxation, so that the anal cushion is easy to move down, and intestinal smooth muscle relaxation can be induced by the difficulty of defecation, but also during pregnancy hemorrhoids onset of a reason. Speaking of causes, it would be unfair not to talk about the effects of childbirth. I have asked many obstetricians whether they have paid special attention to the anal opening of pregnant women during labor and delivery, and most of them have replied that they have not. Some mothers will talk about how my anus is so and so: for example, pain, for example, something comes out of the outside and can not go back, etc. But many young mothers think that this is also an effect of labor, and that is all. But many young mothers think that this is also an effect of the birth, and that’s just the way it is. Hemorrhoids happen, they grow and develop “without realizing it”, and it seems to be an obligatory event for mothers to become mothers! In my experience, I think that pregnant women in labor, is a woman “born hemorrhoids grow hemorrhoids”, the most important link, in this stage, if the attention is much, properly handled, “mother hemorrhoids” will certainly be reduced a lot. If we in other aspects such as diet, defecation, cleaning, anal function exercise, postpartum rehabilitation training in doing more detailed, mother’s ass will even like the original ass! The production of hemorrhoids or anal canal ectopia, the doctor must be reset, reset must be fixed, do not make it out again embedded, embedded consequences may be “no hemorrhoids long hemorrhoids, hemorrhoids plus”! The principle of maternal hemorrhoid prevention is: the mother to speak, the doctor to see! “Caution easy to take refuge, respect fine to far” ah.
