There are many reasons for women to have a noticeable odor after their menstruation. The most common one is that the body’s immunity is lower during menstruation and bleeding causes bacteria to grow and cause odor. The need to use sanitary napkins for a long time during menstruation may also cause odor because they are not breathable. In the case of women with vaginal inflammation, the odor will also be significantly worse during menstruation. This is because during menstruation, as bleeding increases, the breeding environment for inflammation becomes more suitable and bacteria are more likely to multiply. In this case, it is possible that the vaginal inflammation may worsen and cause odor. If there is no odor during non-menstrual periods and there is no vaginal itching, no special treatment is needed. Pay attention to personal hygiene during menstruation and wash the area with warm water. If you have vaginal inflammation, you need to have a routine white belt examination to determine the type of inflammation and then treat the symptoms.
