Mycosis fungoides prolonged treatment usually requires a blood sugar check. When there is a prolonged treatment of mycosis vaginalis, it may be due to high blood sugar caused by untimely blood sugar control, which puts the body in a high-sugar environment. When there is an increase in glycogen in the vagina, the vaginal cells are in a high-sugar environment and the chances of the vagina producing mold increase significantly. The increased sugar content in the vagina favors the growth of molds, and therefore, mycosis vaginalis may occur for a long time. When mycosis vaginalis is not cured, you should consult a doctor and do a comprehensive examination to find out the specific triggering factors, and carry out targeted treatment under the guidance of a professional doctor to avoid delays in the condition.
