I'm getting my tonsils out. My doctor mentioned removed my adenoids as well. Is that really necessary? I thought adenoids will shrink over time?

T&A. Both typically shrink as you get older and theses days tonsils and adenoids are rarely removed. If your doctor feels there is a clinical reason to remove the tonsils it stands to reason the the other tonsil (adenoid) would be removed too.
Tonsils. Sometimes both tonsils and adenoids shrink as we get older,but not always. Ask your doctor why removal of adenoids is recommended. Get a second opinion if you still have concerns or questions. .
