The following hazards are associated with tonsillitis: 1. Inflammation of the tonsils can lead to sore throat, swallowing difficulties, restricted eating, fever, malaise and other symptoms, seriously affecting the quality of daily life. 2. Inflammation of the tonsils can easily lead to peri-tonsillar abscess, parapharyngeal space abscess, inflammation of the cervical lymph nodes, acute sinusitis, bronchitis and pneumonia, and other inflammatory diseases of adjacent structures. The inflammation of tonsils can easily lead to myocarditis, nephritis, arthritis and other diseases. 4. Repeated inflammatory stimulation of tonsils can easily lead to pathological hyperplasia and hypertrophy of tonsils. Once the hypertrophy is easy to block the pharyngeal cavity, resulting in narrowing of the pharyngeal cavity, inducing patients to snore in sleep, open-mouth breathing, breath-holding, and waking up. Over time, it may also lead to hypertension, diabetes and other underlying diseases.
