A light red discharge after intercourse can be seen as a result of damage to the reproductive tract caused by incorrect intercourse, which generally requires no special treatment. However, some diseases such as gynecological inflammation, cervical polyps, cervical cancer, etc. should be excluded. In this case, if there are no other uncomfortable symptoms, it can be observed first and will usually improve on its own. 2. Gynecological inflammation: such as vaginitis and pelvic inflammatory disease, the bleeding can be caused by the contact stimulation of intercourse due to germs infesting the vagina and cervix. In this case, antibiotics should be taken under the guidance of a doctor, such as ceftazidime, penicillin, and mycobacterium preparations and other drugs for treatment; 3, cervical polyps: cervical long-term chronic inflammatory stimulation, easy to grow single or multiple granulation tissue at the mouth of the cervix, because the granulation texture is brittle, easy to contact bleeding, so after intercourse can appear light red discharge. There is no special medicine for this disease for the time being, and polyp removal is often used for treatment. 4. Cervical cancer: cancerous tissues are fragile and have many tiny blood vessels, so it is easy to break down due to contact after intercourse and bleed. Colposcopy and cervical biopsy are needed for clear diagnosis. Early stage cervical cancer can be cured by surgery, and middle and late stage can also be cured by synchronous radiotherapy; 5.Other diseases: cervical erosion, submucosal fibroids and other diseases can cause vaginal bleeding after intercourse. The treatment can also be surgical myomectomy, hysterectomy, etc. Regardless of the condition causing the light red discharge after intercourse, patients should avoid sexual intercourse during the treatment period to avoid infection. You can take a shower to clean your body and avoid bathing and swimming.
