Mothers-to-be can easily induce or aggravate hemorrhoids during pregnancy due to increased abdominal pressure, and according to statistics, the incidence of hemorrhoids in pregnant women is 76%. If a pregnant woman suffers from hemorrhoids with repeated bleeding, it can affect the growth and development of the fetus. In addition, if you have a history of hemorrhoids before pregnancy, pregnancy often aggravates the hemorrhoids, and in serious cases, there will be embedded hemorrhoids, which, if left untreated, lead to localized necrosis of the prolapsed internal hemorrhoid tissue, affecting the health of the mother-to-be herself and the fetus. So, why are you prone to hemorrhoids during pregnancy? What is the best way to treat hemorrhoids? During pregnancy, as the uterus increases during pregnancy, it compresses the pelvic vessels, especially the external iliac artery and the vascular network of the pelvic floor, the pubic reflux is obstructed, the venous pressure increases, and when the abdominal pressure increases again during defecation, the lymphatic reflux is obstructed, leading to increased brittleness of the small perianal vessels, rupture and bleeding, causing hemorrhoids. It has been debated whether to treat hemorrhoids in pregnant women surgically or conservatively. Surgery can be painful and stressful, while dietary control can affect breast milk production. Also, post-operative antibiotic use can have an effect on the baby. Therefore, hemorrhoids during pregnancy should generally be treated conservatively with medication. Unless there is an abscess or an embedded internal hemorrhoid, the patient is in pain or the condition is serious enough to affect the life of the mother and baby, surgery should be performed. It seems that the prevention of hemorrhoids during pregnancy is very important to do the following: 1, three meals normal diet especially breakfast must be eaten to avoid fasting, and eat more food containing more fiber, such as brown rice, malt, whole wheat bread, milk, and fresh vegetables, fresh fruit, try to eat less stimulating spicy food, less carbonated drinks. 2, more water supplementation body water such as insufficient supplementation, constipation will be aggravated, so at least 1,000 ml of water daily. Because of insufficient water, feces can not be formed, and too little feces, can not stimulate the rectum to produce contraction, there will be no stool. Therefore, supplemental water is an important way to reduce constipation. 3, do not hold back not to defecate, that is to say, once the intention to go to the toilet to defecate. Because of the accumulation of feces in the body for a long time, not only will it be difficult to defecate, but also affect the appetite. It is recommended that pregnant women with constipation problems drink more cold water or milk every day to stimulate peristalsis, or drink a glass of cold water or milk immediately after waking up in the morning, which is a good way to help defecate. 4, adequate sleep, moderate activity more activities can enhance gastrointestinal peristalsis, in addition, sufficient sleep, happy mood, mental stress relief, etc. are good ways to reduce constipation. Finally, remind the people who are preparing for pregnancy, if you have a history of hemorrhoids, it is recommended that you have surgery to treat hemorrhoids before pregnancy, free of worries.
