The main reason for the occurrence of pubic blowing is due to the following points: 1. Patients who have a loose pelvic floor tissue after normal delivery, especially the loose vaginal wall tissue, the muscles of the vaginal wall have no strength. In this case, pubic blowing will occur after intercourse. Treatment is mainly to strengthen the exercise of pelvic floor muscles, which can be done by doing anal reduction and anal lifting, and also by doing pelvic floor rehabilitation treatment to relieve the symptoms of pubic blowing. 2. It can also be seen caused by vaginal inflammation. For patients with this condition, they need to go to the hospital to have their vaginal secretions examined. Based on the vaginal secretions examination, we can determine which type of vaginal inflammation is present and then treat it symptomatically. If it is bacterial or trichomonas vaginitis, topical metronidazole suppositories can be used vaginally. In the case of trichomoniasis, the couple should be treated with metronidazole tablets together. In case of mycosis fungoides, topical vaginal nifurtimox vaginal soft capsule is required.
