What are the role of tonsils on your body and what are the impact if it is operated?
Blog Single
In my clinical practice, I often see concerned parents and adults struggling with repeated throat infections, all seeking clarity on one key question: “Doctor, are my tonsils really necessary?” It’s a fair concern. Your tonsils play a quiet but meaningful role in your body, and deciding whether to remove them is not something to take lightly. In this article, I’ll walk you through exactly what your tonsils do, when they become a problem, and what you can genuinely expect if surgery is recommended.
Your tonsils are two small, oval-shaped masses of lymphatic tissue sitting at the back of your throat — one on each side. They are part of your body’s immune system, acting as the first line of defense against bacteria and viruses that enter through your mouth and nose.
Think of them as security guards at the entrance of your body. When germs arrive, your tonsils detect them and trigger an immune response to stop infection from spreading deeper into your body.
In early childhood, this role is especially important. The tonsils are most active between the ages of 3 and 10 years, helping young immune systems learn to fight off common infections. As we grow older, other parts of the immune system become stronger, and the tonsils’ role gradually becomes less critical.
In my experience, tonsils cause trouble when they become chronically infected, enlarged, or inflamed. This condition is called tonsillitis — and it can range from mildly uncomfortable to severely disruptive to daily life.
Common signs that your tonsils may need medical attention include:
✦Recurring sore throat — more than 5–7 episodes per year
✦Swollen tonsils that look red or have white/yellow patches
✦Difficulty swallowing food or even liquids
✦Bad breath that doesn’t go away with brushing
✦Fever and swollen glands in the neck
✦Snoring or sleep disturbances, especially in children
✦Obstructive sleep apnea — pauses in breathing during sleep
I’ve treated many patients in Dhaka who waited too long, assuming their throat pain would simply pass. If you or your child is experiencing more than four to five throat infections a year, that’s a signal worth discussing with an ENT specialist.
Tonsil infections are usually caused by common bacterial or viral infections. The most well-known culprit is Streptococcus pyogenes (strep throat), but viruses like the ones responsible for the common cold and influenza can also inflame the tonsils.
Several factors can make someone more prone to tonsil problems:
✦Early age — a child’s immune system is still maturing
✦Regular contact with other children in school or daycare environments
✦Weakened immunity due to other health conditions
✦Poor ventilation in living spaces, which is common in densely populated urban areas like Dhaka
In some patients, the tonsils themselves become chronically colonized by bacteria, meaning infections keep returning even after antibiotic treatment. This is often when I consider whether surgery is the right next step.
When a patient comes to me with recurring throat pain or suspected tonsil issues, my evaluation typically includes:
✦Physical examination of the throat, neck, and ears
✦Throat swab and culture to identify bacterial infection
✦Blood tests if glandular fever (infectious mononucleosis) is suspected
✦Sleep study (polysomnography) if obstructive sleep apnea is a concern
✦Nasal endoscopy when adenoid involvement is suspected
I always make sure to understand the full picture of a patient’s health before recommending any treatment — surgical or otherwise.
Not every tonsil problem requires surgery. My approach is always to start with the most conservative treatment first.
Non-Surgical Treatment:
✦Antibiotics for bacterial tonsillitis (a full course is essential)
✦Adequate rest and fluid intake
✦Salt water gargles and throat lozenges for comfort
✦Anti-inflammatory medication to reduce swelling
Surgical Treatment — Tonsillectomy:
When infections become too frequent, or when enlarged tonsils are causing breathing problems, I recommend a tonsillectomy — the surgical removal of the tonsils.
This is one of the most commonly performed ENT surgeries in the world, and in my practice, it has genuinely transformed the quality of life for many patients. The procedure is done under general anesthesia and typically takes 30–45 minutes.
Good candidates for tonsillectomy include patients who:
✦Have 7 or more throat infections in one year
✦Have 5 or more infections per year for two consecutive years
✦Suffer from obstructive sleep apnea due to enlarged tonsils
✦Have a tonsillar abscess (a collection of pus around the tonsil)
This is the question I hear most often — and I want to give you an honest, reassuring answer.
In the short term (first 1–2 weeks):
✦You may experience throat pain, earache, and mild fever — this is normal
✦Eating soft foods (yogurt, pudding, soup) is recommended
✦Complete rest is important; avoid strenuous activity
✦Most children return to school within 10–14 days
In the long term:
✦The vast majority of patients experience significantly fewer throat infections
✦Children with sleep apnea often show dramatic improvement in sleep quality and even school performance
✦Some patients report improved appetite and weight gain in children who previously struggled to eat
✦Your immune system does not become weaker — this is the most common fear I address. By the time surgery is recommended, other immune structures (like lymph nodes and adenoids) are fully capable of handling your body’s defense needs
I always tell my patients in Dhaka: the tonsils are helpful when they work properly, but when they become a source of repeated infection and suffering, removing them does far more good than harm
Don’t wait until infections become unbearable. I recommend seeing a specialist if:
✦Your child snores loudly or pauses breathing during sleep
✦Throat infections are happening more than four times a year
✦Antibiotics are no longer controlling infections effectively
✦Your child is struggling to eat, sleep, or concentrate at school
✦You notice one tonsil appears larger than the other (this should always be evaluated)
Early evaluation means earlier relief — and in many cases, we can avoid surgery altogether with the right treatment plan.
You don’t have to keep suffering through repeated throat infections or sleepless nights. Whether you’re exploring your options or already considering surgery, I’m here to help you understand what’s best for your specific situation — not a one-size-fits-all answer.

Your health deserves a specialist who listens. I look forward to meeting you.
Your tonsils serve a real purpose — especially in childhood — but when they become a repeated source of infection, pain, and disruption to everyday life, keeping them is no longer in your best interest. As I’ve shared with countless patients, tonsillectomy is a safe, effective, and often life-improving procedure when it’s the right choice for you. My goal is always to guide you with honesty, care, and the most up-to-date medical knowledge — so that whatever decision we make together, you feel fully informed and supported.
Q1: Will removing my tonsils weaken my immune system?
This is the concern I hear most from parents, and I completely understand it. The honest answer is: no, tonsillectomy does not significantly weaken the immune system. Your body has many other lymph nodes and immune tissues that take over the protective function. In fact, patients who suffer from chronic tonsillitis often find their overall immunity improves after surgery because they are no longer repeatedly fighting infection.
Q2: Is tonsil surgery safe for young children?
Yes — tonsillectomy is one of the safest and most frequently performed surgical procedures in children worldwide. I perform this surgery regularly and take every precaution to ensure your child’s safety and comfort. Recovery for children is typically faster than for adults, and the benefits — better sleep, better appetite, fewer school absences — are often life-changing for the whole family.
Q3: Can tonsils grow back after removal?
In very rare cases, small amounts of residual tonsil tissue can regrow slightly, but a full regrowth is extremely uncommon. When tonsillectomy is performed completely and correctly, the symptoms do not return. This is something I always discuss with my patients beforehand so expectations are clear.
