White stuff on both sides of the tonsils may be caused by tonsillar suppuration, tonsillar stones, tonsillar keratosis or fungal infections. 1. Tonsil suppuration: if the tonsils have an acute inflammatory infection, under the effect of inflammation, the tonsils may become suppurative, resulting in white stuff on both sides of the tonsils. 2. Tonsil stones: If the tonsil crypts become blocked, the secretions will gradually turn into crystalline substances, that is, tonsil stones, resulting in the appearance of white substances on the surface of the tonsils. 3. Tonsillar keratosis: If chronic tonsillitis causes tonsillar keratosis, white spots can be seen in the pharynx, and white secretions will appear on the surface of the tonsils. 4. Fungal infection: If the infection of Candida albicans, Corynebacterium diphtheriae, etc., leads to inflammation of the tonsils, a white membrane will appear. If there are white things on both sides of the tonsils, it is recommended to go to the ear, nose and throat department of the regular hospital as soon as possible to find out the cause of the disease in time and take targeted treatment measures.
