However, sometimes the tonsils themselves can become infected, leading to a condition called tonsillitis.
If tonsillitis becomes recurrent, chronic, or causes complications such as difficulty breathing or swallowing, sleep apnea, or bacterial infections like strep throat, a healthcare provider might recommend tonsillectomy—a surgical procedure to remove the tonsils. Tonsillectomy is a common treatment for persistent or severe tonsillitis.
In many cases, especially in childhood, the tonsils play an essential role in the immune system's development and may shrink in size as a person gets older. However, they generally continue to function as part of the body's defense against infections.
