The main symptoms of trichomonal vaginitis are increased vaginal discharge and vulvar itching. The discharge is generally a grayish-yellow, frothy, thin liquid with a foul odor. Women with trichomonal vaginitis can detect the infection through a routine vaginal discharge test. It is recommended to visit the gynecology department of a local formal hospital and follow the active treatment under the guidance of a clinical doctor. During the treatment period, sexual intercourse should be avoided, vulvar hygiene should be maintained, and loose, breathable underwear should be worn and changed frequently. The diet should be light, avoiding raw, cold, spicy, and other irritating foods.
