There are two main types of brown blood secretion factors, physiological factors and pathological factors, among which vaginal inflammation and cervical lesions are common. If the brown blood is due to physiological factors, there is no need to be nervous as it is a normal physiological phenomenon for women. However, brown blood from the vagina caused by pathological factors needs to be taken seriously and treated accordingly if necessary. Physiological factors: When a woman is ovulating, the follicle ruptures and the estrogen level fluctuates, resulting in a small amount of endometrial exfoliation, which causes a small amount of vaginal bleeding, which can be brown. Pathological factors: 1, vaginal inflammation: some patients with senile vaginitis or trichomonas vaginitis may have symptoms of brown blood in the discharge, as well as itching and burning sensation in the vulva, and in serious cases, blood will appear. Bleeding, brown when the amount is small. If the ultrasound examination indicates that there is a gestational sac in the uterus and there is a fetal heart, it means that it is a pre-eclampsia and should be treated with fetal preservation. If the fetal heart and fetal bud cannot be detected in the uterus during ultrasound examination, but the gestational sac or fetal heartbeat can be seen in the fallopian tube, cervix, ovaries and other extra-uterine parts, ectopic pregnancy can be diagnosed, and then methotrexate can be given to make the embryo fall off and die naturally, or surgical treatment can be taken. In addition, lesions such as submucosal fibroids, endometrial polyps, and staphyloma can cause brown blood to appear in the lower body, so there are many causes of brown blood that should be treated promptly by a doctor. Regardless of whether the test results suggest a normal physiological condition or a disease, you should pay attention to keeping your vulva hygienic in your daily life, wash your vulva with warm water and do not wear tight pants to avoid infection. Keep exercising and get enough sleep to strengthen your immune system. Reasonable dietary arrangements, pay attention to nutritional balance, and at the same time to maintain a good psychological state.
