Tonsillectomy is a common surgical procedure, especially in children. Doctors may recommend it for patients who experience frequent throat infections or difficulty breathing during sleep. But it’s natural to wonder: Are there any side effects of tonsil removal? Here's what you need to know. (1)



Is Tonsillectomy Harmful?

Tonsillectomy is a safe and effective procedure. The vast majority of people recover well without experiencing any serious complications. However, like any surgery involving the throat, it can carry some temporary side effects, and serious complications are rare. (2)(3)


The risk of complications depends on several individual factors such as age, overall health, and the surgical technique used. Still, the benefits usually outweigh the risks, particularly when enlarged or infected tonsils significantly affect a patient’s quality of life. (4)


Doctors take all necessary precautions and use advanced medical techniques to minimize risks and ensure a smooth recovery. (4)


What Are the Possible Side Effects of Tonsillectomy?

Common temporary side effects that may appear in the first few days after surgery include: (2)

  • Moderate to severe sore throat for 1–2 weeks
  • Ear, jaw, or neck pain
  • Bad breath for up to two weeks
  • Low-grade fever for a few days
  • Difficulty swallowing or a feeling of something stuck in the throat
  • Swelling of the tongue or throat
  • Irritability or sleep disturbance in children
  • Nausea or vomiting
  • Temporary changes in taste or voice
  • Minor bleeding at the surgery site
  • A white coating on the throat or tongue (1)


Serious complications are rare, but may include:

  • Severe bleeding during or after surgery
  • Infection at the surgical site
  • Adverse reaction to anesthesia
  • Breathing difficulties (3)


When to See the Doctor

Always follow your doctor's post-operative care instructions. Contact your doctor if:

  • Symptoms do not improve or become more severe
  • You experience any of the following concerning symptoms: (3)
  • Heavy bleeding
  • Persistent vomiting
  • Trouble breathing
  • High fever


When Should You Consider a Tonsillectomy?

Your doctor will decide whether tonsil removal is appropriate based on several factors, including: (5)

  • Frequency of infections:
  • More than 7 throat infections in one year
  • 5 or more infections per year for two consecutive years
  • 3 or more infections per year for three consecutive years


  • Severity of symptoms:
  • If symptoms significantly impact your or your child’s quality of life (e.g., trouble breathing or sleep issues)


Does Tonsil Removal Weaken the Immune System?

No, tonsillectomy does not weaken the immune system. The body remains capable of fighting infections effectively.

To clarify:


The tonsils are part of the immune system and help fight infections, particularly in children. However, if the tonsils are frequently inflamed or enlarged, they can do more harm than good—making removal medically necessary in some cases.


Studies show that the immune system adapts well after tonsil removal, as other parts of the immune system—like the lymph nodes—continue to function normally. Most people do not experience a noticeable decrease in immunity after surgery. (4)
