Removing your tonsils is a good idea in specific situations, but not as a default. The surgery makes the most sense when you’re dealing with frequent, documented throat infections or when enlarged tonsils are blocking your airway during sleep. Outside those scenarios, the risks and recovery often outweigh the benefits, and a watch-and-wait approach tends to work just as well.
When Removal Is Worth It
The clearest reason to remove tonsils is recurrent throat infections that hit a specific threshold: seven or more episodes in a single year, five or more per year for two consecutive years, or three or more per year for three consecutive years. These are known as the Paradise criteria, and they form the backbone of clinical guidelines in both the US and UK. Each episode needs to be documented with at least one objective sign, such as a fever above 101°F, swollen lymph nodes in the neck, pus on the tonsils, or a positive strep test.
If you or your child falls below those numbers, the American Academy of Otolaryngology recommends watchful waiting rather than jumping to surgery. There are exceptions: people with multiple antibiotic allergies, a history of peritonsillar abscess, or a rare condition called PFAPA syndrome (which causes recurring fevers and mouth sores) may still benefit from surgery even without meeting the infection count.
The second major reason is obstructive sleep apnea caused by oversized tonsils, particularly in children. When large tonsils physically block the airway during sleep, removal can improve breathing, school performance, bedwetting, behavioral problems, and even growth in kids who’ve fallen behind. That said, roughly half of children still have some residual sleep apnea after surgery, so it’s not always a complete fix.
Less commonly, tonsils are removed when one side is noticeably larger than the other and cancer needs to be ruled out. In one study of patients with asymmetric tonsils and no other warning signs, about 5% turned out to have lymphoma hidden in the tissue.
What Happens If You Skip Surgery
For recurrent throat infections, the difference between surgery and doing nothing is real but modest. In clinical trials, children who had their tonsils removed experienced about 3.5 fewer sore throat episodes over two years compared to children who didn’t. By the second year, kids in the surgery group averaged roughly one sore throat every seven to eight months, while kids in the watchful waiting group averaged about one every three months. School absences also dropped: children who kept their tonsils missed about five days of school per year, compared to two to three days for those who had surgery.
The pattern that makes this tricky is that throat infections tend to become less frequent over time regardless of whether you have surgery. Many children who technically meet the criteria for removal end up improving on their own within a year or two. This is why guidelines frame tonsillectomy as an option rather than a strong recommendation for recurrent infections alone.
Long-Term Effects on Your Immune System
Tonsils are part of your immune system. They sit at the entrance to your throat and act as a first line of defense, sampling bacteria and viruses that enter through your mouth and nose and helping your body learn to fight them. Removing them doesn’t leave you defenseless, since other immune tissues pick up much of the work, but it’s not entirely without consequence.
A large Danish study tracking over a million children who had tonsillectomies before age nine found significantly higher rates of respiratory infections, asthma, and other infectious diseases later in life. Other research has linked tonsil removal to a modestly increased risk of Hodgkin’s lymphoma and certain autoimmune conditions. These elevated risks are generally small in absolute terms, but they’re worth weighing against the benefits, especially when surgery is being considered for borderline cases.
Recovery Is Harder for Adults
Recovery from a tonsillectomy takes 10 to 14 days on average, and the experience differs dramatically depending on your age. Children typically bounce back faster, with less pain and fewer complications. Adults consistently report more intense pain and take longer to return to normal activities.
Pain in the throat lasts one to two weeks and is often worst between days three and seven, when the scabs at the surgical site begin to shift. Adults report pain scores roughly ten times higher than children in some studies. The benchmark for going back to work or school is straightforward: you should be able to eat regular food, sleep through the night without waking, and manage without pain medication.
Bleeding is the most serious complication. Across all surgical techniques, about 1% of patients experience bleeding in the first 24 hours. The bigger concern is delayed bleeding, which happens days later and occurs at a rate of about 5.8% overall. Adults face substantially higher rates: one study found late bleeding in 20% of adult patients compared to about 6% of children. When delayed bleeding does happen, most cases resolve on their own or with minor intervention, but a small percentage require a return to the operating room.
Who Benefits Most
The people who gain the most from tonsillectomy are children with severe sleep apnea caused by enlarged tonsils and anyone, adult or child, whose life is genuinely disrupted by frequent, severe throat infections that meet the clinical thresholds. For a child missing weeks of school each year or an adult cycling through multiple rounds of antibiotics annually, the surgery can be transformative.
For people with occasional sore throats or mildly enlarged tonsils that aren’t causing breathing problems, the calculus shifts. The surgery carries real pain, a meaningful bleeding risk (especially for adults), and potential long-term immune effects. In those cases, waiting and tracking your infection frequency over the next year or two is a reasonable and evidence-supported choice.
