As a guy, what are you most afraid of? “Waiting for your girlfriend to go to the bathroom every time you go shopping with her.” It seems like there is always a queue in the ladies’ room! If your girlfriend happens to be “constipated” at this time, you will not be more frantic. Why does constipation like to favor women? Women often have the following types of constipation: 1, constipation during pregnancy. Foreign reports 40% of women during pregnancy can occur constipation. Pregnancy due to the formation of the corpus luteum, increased secretion of progesterone, the latter can inhibit intestinal peristalsis, reduce the sensitivity of the intestine to stimulation and constipation. After 6 months of pregnancy, the uterus increases, compressing the intestinal canal and pelvic vessels, causing pelvic veins to stagnate, and rectal peristaltic function decreases, causing constipation. 2, constipation during childbirth. After delivery, due to the rectus abdominis and pelvic floor muscle is swollen by the uterus swelling loose, and even part of the muscle fiber fracture, so that the abdominal wall muscles, intestinal wall muscles, anal raphe muscles and other muscle groups involved in defecation tension is reduced, coupled with maternal weakness, can not rely on abdominal pressure to assist defecation, excessive retention of feces in the intestines, water overabsorption and constipation. After delivery, pain caused by birth canal laceration, perineal incision, pain or fear of pain can also cause bowel inhibition. At the same time, several days of postpartum bed rest, reduced activity, intestinal peristalsis is weakened, is also one of the reasons affecting defecation. 3, rectal emptying disorder type constipation. It is manifested as a sense of incompleteness after defecation, a feeling of falling, a feeling of heavy pressure in the perineum or the need for manual assistance in defecation. Due to the unique physiological anatomical characteristics of women, resulting in the prevalence of this type of constipation is much higher than that of men. Including the following situations: 1, rectal protrusion type constipation. The main cause of constipation in women is rectal protrusion, which accounts for 96.5% of menstrual mothers. Mainly due to childbirth, birth injuries and other causes of damage to the rectovaginal septum, manifested as the rectal anterior wall mucosa is bag-shaped protrusion into the vagina. When defecation, feces fall into the bag, so that the feces to the direction of the vagina to accumulate and can not be emptied. 2, posterior tilting of the uterus type constipation. The normal uterus is tilted forward between the bladder and rectum. Due to the incomplete development of the uterus or injury in childbirth, multiple births, improper postpartum maintenance and pelvic inflammatory disease, etc., can lead to the uterus tilted backward, pressing the front wall of the rectum, so that the intestinal cavity is narrowed and bent, resulting in fecal passage obstacles. Clinical manifestations are poor defecation, thin flat stools, and a sense of incompleteness after the stool. 3.Endorectal loop. The rectal cavity can be enlarged and the rectal mucosa can be relaxed by rectal palpation. 4.Anal sphincter dystocia. When women squat to urinate, the external anal sphincter and puborectal muscle are in a relaxed state, and the internal sphincter is in a tense state in order to restrain the discharge of feces. Urinary tract infection when the frequency of urination, urinary urgency and other symptoms to promote the persistence of the above factors. 5. Hypertrophy of the puborectalis muscle. On rectal examination, the anal canal may be lengthened, the tension is increased, the puborectalis muscle is thickened and hardened, and there is pressure pain, and the puborectalis muscle contraction is not obvious when the patient is asked to do anal contraction. Fecal imaging shows that the anal canal does not open during defecation, and there may be a “shelf sign” at rest and during forceful defecation. 6. Sliding internal hernia of the rectal uterine sink. Under normal circumstances, the peritoneum in the pelvis of women folds back from the bladder to the uterus and then to the anterior wall of the rectum, forming a recto-uterine depression between the uterus and the rectum, which can deepen and form a hernia sac if the tissue around the rectum is relaxed. When defecating, the sigmoid colon herniates into it, compressing the rectum and producing a series of discharge obstruction and downward symptoms. 7. Pelvic floor spasm syndrome. Rectal palpation can reveal tight anal sphincter, hardening of the posterior side of the rectal ring of the anal canal, and tenderness. 8.Endometriosis. It is a complication of a variety of gynecological surgeries and is common in women after marriage and childbirth. Its ectopic place is mostly in the rectal trap, forming a solid nodule or mass.
