Inflammation of the tonsils in general does not cause proteinuria, but it is possible to cause proteinuria in combination with acute nephritis. Tonsillitis alone is not associated with abnormal urine tests. However, if streptococcal infection of the upper respiratory tract causes inflammation of the tonsils, and the inflammation is not treated in time, the pathogen has a certain chance to spread further to the kidneys with the blood circulation and cause acute nephritis. Acute nephritis can cause abnormal proteinuria due to increased permeability of the basement membrane. Tonsillitis patients are recommended to go to the regular hospital for timely diagnosis and treatment, can be under the guidance of the doctor to take a moderate amount of broad-spectrum antibiotics such as cephalosporins (cefuroxime) to achieve the purpose of anti-inflammatory as soon as possible, so as to avoid delays in the condition.
