###Human: Why am I having fishy odor from vagina? ###Assistant: Hello. Yes, you have heard right that if vaginal infections are left untreated they may lead to PID and infertility. It is a serious issue which must be dealt with promptly and appropriately. Bacterial vaginosis leads to change in vaginal flora and pH which results in fishy odor and discharge. Metronidazole is the recommended treatment for it but as you say it has not affected you then I would suggest that you must not neglect it and get yourself fully checked by having vaginal swabs tested and getting exact diagnosis and treatment. Secondly, hygiene is of very much importance with regards to vaginal discharge. Some tips are as below: Keep the vaginal area clean and wash with plain water as much as possible. Avoid any cosmetic products over the vaginal area and wear cotton rich undergarments.
