Can irregular periods trigger vaginitis? Irregular menstruation and vaginitis are not necessarily related and irregular menstruation is not a cause of vaginitis. Can vaginitis cause irregular periods? Vaginitis also causes irregular periods. Some vaginitis may manifest as blood in the leukorrhea or a small amount of irregular vaginal bleeding (most common in senile vaginitis), but never up to menstrual-like bleeding. Can I get vaginitis if I use pads a lot? Why? Improper use of pads can lead to vaginitis. Long-term use of non-breathable pads can make the vulva and vagina “poorly ventilated” and too moist, which are the “preferred” environments for disease-causing bacteria. How should I use pads during non-menstrual period? Use pads that are breathable and do not wear them for a long time, especially avoid using them 24 hours a day. If the secretion is very little, you can not use pads at all. You should know that your “private parts” also need to breathe and take a deep breath. What can I do to prevent vaginitis during menstruation? Vaginitis tends to recur before and immediately after menstruation. The use of sanitary napkins and the opening of the menstrual blood to the outside world during menstruation also make it easier for infections to occur. Therefore, it is important to use sanitary napkins with good ventilation during menstruation and to change them when they are wet so that menstrual blood does not become a “culture medium” for bacteria. Patients who have vaginitis before menstruation are advised to review the leukorrhea after menstruation to make sure the treatment is complete.
