The tonsils are an immune organ of the body with special physiological functions and are generally recommended to be preserved. However, because tonsillar lesions cause some more complex changes in the body, they need to be removed. Excision is also safe. There are two reasons for tonsil removal, recurrent streptococcal tonsillitis is the main reason for tonsillectomy, and possibly because enlarged tonsils can directly block the airway and cause apnea, because it is safe to remove the tonsils for life. In addition to some life-threatening complications, removal of the tonsils can cause side effects, and many people experience nausea and vomiting, sore throat, difficulty swallowing, low-grade fever, bad breath, earache and fatigue after the procedure. Although removal of the tonsils usually helps treat some chronic infections, not all are effective, and strep infections can still occur after removal of the tonsils, and the infections are usually no worse after the procedure than they were before. As physicians gradually understand the dangers of sleep apnea, the number of tonsillectomies being performed is increasing. The premise is that there are indications for the procedure. Generally, doctors do not recommend removal of the tonsils, but if the disease will affect a person’s health, removal is the best way to go. Although there will be some adverse effects after removal, removal will also eliminate some of the complications caused by recurrent tonsillitis.
