Eating sweets can easily trigger mycosis vaginalis. Patients should adhere to their medication and pay attention to eating less or no sugary foods during the medication period. Women with a sweet tooth are more prone to mycosis vaginalis because mycobacteria tend to develop and reproduce in a sweet environment. If the intake of sugar is excessive for a long time, elevated blood sugar can increase glycogen and vaginal acidity in the vagina, leading to an increase in Candida and causing mycosis vaginalis or an increase in inflammation. If patients have frequent recurrence of mycosis vaginalis, they should test their blood sugar. If their blood sugar is high or they have diabetes, they should first regulate their blood sugar to normal values to facilitate complete cure of the disease. In addition, patients with mycosis vaginalis should change their underwear regularly during treatment, wash their vulva with warm water, and avoid using irritating vaginal cleansers. The diet should be light and easy to digest, no smoking and alcohol, no cold, greasy and stimulating foods, more vitamin-rich foods such as vegetables and fruits, rest on time and exercise. Patients with mycosis fungoides are prone to negative emotions such as irritability, tension and anxiety due to external itching. Family members should be considerate and caring to relieve mental tension, encourage patients to adhere to treatment and help build confidence to cure the disease.
