The role played by the tonsils in the body’s immune system is currently under study. It is generally believed that the tonsils play a role in fighting disease during the teenage years. Studies have shown that the tonsils contain natural killer cells that directly kill pathogens. Furthermore, the tonsil tissue secretes an immunoglobulin called IgA, while the white blood cells in the tonsils can also differentiate into antibody-secreting cells.
The question many people ask is whether tonsil removal reduces immunity?
In fact, as previously analyzed, after the age of 5 to 6, the immune function of the tonsils is gradually replaced by other organs, so there is no need to worry about this.
It is important to emphasize that it is not that ENT doctors like to recommend tonsillectomy to their patients, but rather that they evaluate whether surgery should be performed according to the patient’s condition. Of course, if a pediatrician or internist believes that a patient’s heart disease, arthritis or nephritis is strongly associated with tonsillar infection, then tonsillectomy is also necessary.
