Risks and benefits of tonsillectomy

Overview

A tonsillectomy is a surgery to remove the tonsils, which are two small glands at the back of your throat. The surgery is done to treat problems like frequent tonsil infections (called tonsillitis) or trouble breathing during sleep (called obstructive sleep apnea).

Yes, tonsillectomy is a common surgery, especially in children. However, the number of surgeries has gone down in recent years because doctors now recommend it only when there is a clear benefit.

It mostly affects children between the ages of 2 and 16, but adults can also have it if they have severe or frequent tonsil problems. It is slightly more common in boys than girls.

Symptoms

Causes

Main causes

• Recurrent tonsillitis (frequent bacterial or viral infections of the tonsils)
• Enlarged tonsils that block the airway during sleep (obstructive sleep apnea)

Risk factors

• Being a child, especially between ages 2 and 10
• Frequent exposure to other children, like at daycare or school
• Weakened immune system

When to see a doctor

See a doctor urgently if:

• If you or your child has trouble breathing or swallowing
• If fever is very high and does not respond to medicine
• If there is severe pain that stops eating or drinking

Book a routine appointment if:

• If you have had 7 or more episodes of tonsillitis in one year
• If your child snores loudly and has pauses in breathing at night

Diagnosis

A doctor will ask about your or your child’s symptoms and how often they happen. They will look at the throat with a light and may feel the neck for swollen glands.

Tests that may be done

• Throat swab: a cotton swab is rubbed on the back of the throat to test for bacteria like strep
• Sleep study (polysomnography): done if sleep apnea is suspected, often at a hospital overnight
• Blood tests: rarely needed, but can check for infections or other causes

What to expect at your appointment

The doctor will explain the risks and benefits of tonsillectomy, including recovery time, pain, and possible complications. They will only recommend surgery if the benefits clearly outweigh the risks. You will have time to ask questions and decide.

Treatment

In most cases, tonsil infections or enlarged tonsils can be managed without surgery. Treatment includes home care, medication, and sometimes watchful waiting. Surgery is reserved for severe or persistent problems.

Self-care at home

• Rest and drink plenty of fluids (water, warm tea with honey for children over age 1)
• Gargle with warm salt water to soothe a sore throat
• Use over-the-counter pain relievers like paracetamol or ibuprofen (follow the label instructions or ask your pharmacist)
• Eat soft foods (yogurt, soup, applesauce) when swallowing hurts

Medical treatments

If the tonsillitis is caused by bacteria, the doctor may prescribe antibiotics. These are usually taken for 10 days. It is important to finish the whole course even if you feel better. For viral infections, antibiotics will not help, and the infection will go away on its own with rest and fluids.

Living with this condition

After a tonsillectomy, it takes about 10 to 14 days to fully recover. You will have a sore throat and may have ear pain. Drinking fluids is very important to stay hydrated and help healing. Avoid hard, sharp, or spicy foods. The throat will look white or yellow as it heals – this is normal.

Lifestyle tips

• Plan for at least 2 weeks off from school or work
• Avoid strenuous activity and heavy lifting for 2 weeks to reduce bleeding risk
• Humidify the bedroom air to soothe the throat at night

Diet and exercise

Stick to a soft diet for the first week: ice cream, pudding, smoothies, mashed potatoes, scrambled eggs. Avoid crunchy, sharp foods like chips or nuts. Drink at least 1 liter of fluid a day unless the doctor says otherwise. After 2 weeks, you can slowly return to normal eating and light exercise.

Mental health and emotional wellbeing

Surgery can be stressful for both children and adults. Children may feel scared or anxious before the operation. Adults may worry about pain or time off work. It is normal to feel this way. Talk to your healthcare team about any concerns. After recovery, most people feel much better because the problem (frequent infections or poor sleep) is gone.

Prevention

You cannot fully prevent tonsil problems, but good hygiene can reduce infections. Wash hands often, avoid close contact with people who have sore throats, and do not share cups or utensils. For sleep apnea, there is no prevention, but early treatment can prevent complications.

Vaccines

Vaccines like the flu shot and pneumococcal vaccine can help prevent some infections that can lead to tonsillitis. Talk to your doctor about recommended vaccines.

Screening programmes

There is no routine screening for tonsil problems. You should see a doctor if you have frequent sore throats or breathing issues. For sleep apnea, a sleep study can confirm the diagnosis.

Complications

If left untreated

• Untreated tonsillitis can lead to a peritonsillar abscess (a pocket of pus) that needs drainage
• Severe blockage of the airway from enlarged tonsils can cause sleep apnea, which increases the risk of heart problems and daytime sleepiness
• Rarely, untreated strep throat can cause rheumatic fever or kidney inflammation

Long-term outlook

With proper treatment, most people with tonsil problems get better. For those who need surgery, the benefits—fewer infections and better sleep—often outweigh the risks. Recovery can be tough but most people are back to normal within 2 to 3 weeks. Complications from surgery are uncommon and can be managed. Overall, the outlook is very good.
