Irregular vaginal bleeding also needs to be checked for the presence of benign and malignant tumors of the reproductive organs, such as submucosal fibroids, endometrial cancer and precancerous lesions, benign and malignant diseases of the cervix. All these need to be clarified by relevant examinations, of which the most basic one is gynecological examination. If there is any abnormality in gynecological examination, further corresponding auxiliary examinations can be selected. Therefore, gynecological examination is sometimes very necessary. Most patients think that gynecological examination cannot be done when they have vaginal bleeding, including some doctors may use this as a reason not to perform gynecological examination, and simply focus on whether it will increase the chance of infection, but this is actually incorrect as well. Infection needs to be avoided, and misdiagnosis needs to be avoided even more. I treated a patient who came in with sudden heavy vaginal bleeding and no abnormalities were seen in the uterine adnexa on ultrasound. The patient stopped bleeding within two days, but within a month, she had heavy vaginal bleeding again. This kind of fibroids prolapsed inside the vagina is difficult to detect by abdominal ultrasonography. There are also some bleeding caused by cervical diseases that do not undergo gynecological examination and rely solely on ultrasonography, which can lead to missed diagnosis and delayed treatment. Therefore, it is a very one-sided understanding that if you have vaginal bleeding, you cannot have a gynecological examination. It must be based on the specific situation, and it is only reasonable to suspend the examination if you have had a gynecological examination in the recent past and are bleeding. Other diseases involving vaginal bleeding are other pregnancy-related uterine bleeding, genital inflammation, injury, exogenous hormonal influence and systemic diseases, which are mostly not difficult to distinguish due to clear etiology or specificity of clinical symptoms.
