Ms. Du, a reader in Guangzhou, asked: since my pregnancy entered the middle and late stage, my hemorrhoids have become more and more serious and often bleed. Will this cause infection and affect the baby in my stomach?
Huang Hongxiang, deputy chief physician of anorectal surgery of Shanghai Xinhua Hospital, answered: as the saying goes, "ten pregnancies and nine hemorrhoids", the arterial and venous blood flow in the pelvic cavity increases during pregnancy (the arterial blood flow in the pelvic cavity increases by about 25%), the blood flow speed of the inferior vena cava slows down, and the regulation of anal pad arteriovenous anastomosis is disordered, resulting in stasis of venous blood flow, tissue edema, thrombosis and hemorrhoids; With the increase of gestational weeks, the uterus increases, compresses the inferior vena cava, affects the reflux of hemorrhoids, and induces or aggravates hemorrhoids.
Hemorrhoids are benign diseases that generally do not affect the fetus. However, if severe hemorrhoids bleeding leads to anemia in pregnant women, or thrombus causes severe pain and stimulates uterine contraction, it may affect the fetus. Therefore, hemorrhoids during pregnancy must be treated in time.
For pregnant women, hemorrhoids are the first choice for conservative treatment, such as warm water and hot compress 2 ~ 3 times a day, especially for external hemorrhoid edema and anal swelling; Side lying hot compress is adopted. Squatting sitting bath is not recommended, especially in the middle and late stages of pregnancy. Pregnant women can also take lactulose, probiotics and other drugs to regulate intestinal function and improve constipation. If medication is needed, it is recommended to use it under the guidance of an anorectal specialist.
