The tonsils are also known as lymphoid tissue, which is designed to prevent bacterial infections in the throat. These glands can be quite helpful, but this does not mean having the tonsils removed makes you more susceptible to infection. The truth is that some children experience fewer throat infections after they have their tonsils removed. There are other parts of the body that take on the protective role.
Today, antibiotics are more common than tonsillectomies. Still, they are pretty common among children when frequent infection may result otherwise. Additionally, the surgery could be necessary because the tonsils block the airway.
Please check with your doctor regarding any health related questions or issues.
