Women are prone to hemorrhoids or aggravation of existing hemorrhoid symptoms due to special physiological factors such as menstruation, pregnancy and childbirth. The etiology and treatment principles of hemorrhoids during pregnancy: For hemorrhoid patients within 3 months of pregnancy, the progesterone in the body is low during this period, and various stimuli in the perineum can reflexively cause uterine and vaginal contractions, resulting in miscarriage; in the pre-embryonic period, various drugs can easily affect the fetus and cause malformations, making this period an absolutely dangerous one. Conservative treatment should be used as much as possible during this period. In the 4th to 7th month of pregnancy, the placenta can produce enough progesterone and the general injury stimulation of the perineum is less responsive to the uterus and vagina, entering a relatively safe period. Less damaging treatment is feasible for thrombosed hemorrhoids, anal fissures with severe pain and bleeding stage I and II internal hemorrhoids. It should be contraindicated for complicated, heavily damaged and habitual abortion and preterm delivery. In the 8th to 10th month of pregnancy, the fetal head descends into the pelvis to compress the pelvic veins due to the enlargement of the fetus, so that the venous reflux is obstructed. The effects of progesterone, estrogen and aldosterone make water and sodium retention and increase tissue edema, and the effects of progesterone and oxytocin relax the pelvic floor fascia and internal and external rectal sphincters, which, together with constipation and prolonged standing and squatting, can easily induce inflammatory external and internal hemorrhoids to prolapse and bleed. At this stage, conservative therapy should be the main treatment, through PP powder, Chinese medicine sitz bath to relieve symptoms. Try not to use sclerotherapy, and for severe hemorrhoids, it is best to treat them surgically after delivery or weaning of the baby if possible. Preventive and therapeutic measures for hemorrhoids during pregnancy: Patients are advised to consume a high fiber diet, drink more water, have regular bowel movements, maintain local hygiene, hot water sitz baths, etc. In case of constipation, appropriate laxative or rectal mucosal protector can be consumed. Life more high-fiber food, food such as whole wheat flour, corn, cereal; fruit dates, peanuts, sesame seeds with skin, walnuts, almonds; mushrooms dried mushrooms, purple cabbage, silver fungus, kelp; dry beans soybeans, green soybeans, kidney beans, vegetable beans, mixed beans; vegetables leek, dried white bamboo shoots, cabbage, eggplant cauliflower, etc.. If constipation is heavy, appropriate laxatives such as psyllium, compound ginkgo biloba extract capsules (Jingkofu), hydroxy rutin, etc. can be consumed under the guidance of physicians. In case of bleeding, you can use compound cornic acid suppositories appropriately or take vitamin C orally; in case of anal redness and pain, Jiuhua cream can be used externally, and ointments containing musk are prohibited. After 36 weeks of pregnancy, the anal and perineal tissues are edematous, congested and fragile, and the wounds are difficult to heal completely. The treatment of hemorrhoids during pregnancy is as conservative as possible to avoid the occurrence of premature birth and miscarriage. Also local anesthetics and some antibiotics used for surgery during pregnancy can cause fetal malformations. Sclerotherapy injections are an effective means of preventing the enlargement of hemorrhoids. The consent of the patient, family and obstetrician should be sought before the procedure, and the procedure should be performed with the assistance of an obstetrician. Although hemorrhoids are a minor disease that rarely leads directly to death, they can be fatal if improperly treated and serious complications arise. Therefore, surgical treatment of hemorrhoids should not be taken lightly.
