Pregnant women are more prone to vaginitis compared to ordinary women of the same age for the following reasons: 1. Increased secretion: Because of the increased level of estrogen and progesterone in pregnant women’s bodies during pregnancy, it will lead to increased leukorrhea secretion, and in the humid environment of the vagina, failure to wash in time will easily cause the breeding and reproduction of germs, which will lead to vaginitis; 2. Change in acidity: Because of the The increase of estrogen level, lactobacillus in the vagina will break down the glycogen and make the vagina in a weak acidic environment, which is conducive to the growth of fungus, leading to fungal vaginitis infection in pregnant women. 3. Blocked blood circulation: As the fetus grows, the uterus will gradually increase in size, which will compress the pelvic cavity and lead to pelvic stasis and poor blood circulation, and bacteria cannot be removed in time, which will easily lead to the occurrence of vaginitis. Therefore, in daily life, pregnant women should pay attention to keep their vulva clean and hygienic, change and wash their underwear regularly, avoid sitting for a long time, reduce the consumption of spicy and stimulating food, pay attention to increase nutrition and improve resistance. If there is abnormal itching, increased secretion or change in the color of secretion in the vulva, you should go to the hospital for relevant examinations in a timely manner, and after a clear diagnosis, seek symptomatic treatment under the guidance of the doctor.
