Tonsil Removal in Kids: 7 Side Effects Parents Should Know About

Tonsil removal, medically known as tonsillectomy, is a common operation in children. It may be recommended when a child has frequent episodes of tonsillitis, enlarged tonsils that cause breathing difficulties, or obstructive sleep apnoea. Although the procedure can improve sleep, breathing, and quality of life, children may experience some side effects during recovery.

Most children recover well with adequate pain relief, hydration, and rest. However, parents should understand the possible complications and know when to seek medical help.

1. Throat Pain and Difficulty Swallowing

“Throat pain is one of the most common side effects after tonsil removal. Children may experience significant discomfort when swallowing food, drinking water, or even talking. The pain can also spread to the ears because of shared nerve pathways,” shares Dr (Major) Rajesh Bhardwaj, ENT Specialist and Head & Neck Surgeon, Founder and Medical Director of MedFirst ENT Centre, Vasant Vihar, New Delhi.

Pain often lasts for around one to two weeks and may temporarily worsen between the fifth and seventh day after surgery. This does not necessarily mean that the wound is infected.

• Doctors may recommend age-appropriate painkillers to keep the discomfort under control. 
• Parents should follow the prescribed dosage and avoid giving medicines that have not been approved by the treating doctor.

2. Risk of Bleeding

Bleeding is one of the most important complications of tonsillectomy. It can occur within the first 24 hours after surgery or several days later, often when the healing surface begins to separate.

A small amount of blood may sometimes be noticed, but any fresh blood from the mouth or nose, or blood in vomit after tonsil surgery, requires urgent medical assessment. Parents should not wait to see whether it stops on its own.

If a child develops bleeding, take them to an emergency department immediately. Significant bleeding can lead to serious blood loss and may require another procedure.

3. Nausea and Vomiting

Some children experience nausea or vomiting after surgery. This may result from the anaesthesia, pain medicines, or swallowed blood.

Repeated vomiting can make it difficult for a child to drink enough fluids, increasing the risk of dehydration. Parents should offer small, frequent sips of fluids once the child is fully awake and able to swallow safely.

Persistent vomiting, vomiting blood, or an inability to keep fluids down requires medical advice.

4. Dehydration

Children may drink less than usual because swallowing hurts. This can lead to dehydration, particularly if they also have a fever or are vomiting.

Signs include passing urine less frequently, dark-coloured urine, a dry mouth, fewer tears when crying and unusual tiredness.

Encourage frequent sips of water or other suitable fluids. Ice lollies and cool drinks may help some children, provided they can swallow safely. Seek medical advice if the child is unable to drink adequately or shows signs of dehydration.

5. Bad Breath and Changes in Voice

Bad breath is common during recovery because a whitish or yellowish coating forms over the healing areas where the tonsils were removed. This is usually part of normal healing and does not automatically indicate an infection.

A child's voice may also sound different for a short time, particularly if the enlarged tonsils previously affected speech or the shape of the space at the back of the mouth. In some children, a nasal-sounding voice may persist and needs medical review.

These changes generally improve as healing progresses.

6. Fever and Infection

A mild rise in temperature can occur after surgery. However, a persistent or high fever, worsening pain, increasing swelling, or a child who appears increasingly unwell should be assessed by a doctor.

Infection is possible, although it is not the most common cause of discomfort during recovery. Parents should not start antibiotics without medical advice.

Besides, a study published in the Journal of Family Medicine and Primary Care shows that tonsillectomy can have a long-term impact on children's immune system.

7. Breathing Problems and Anaesthesia-Related Risks

Tonsillectomy is performed under general anaesthesia. Temporary nausea, drowsiness and throat irritation may occur afterwards. Serious anaesthesia-related complications are uncommon, but breathing problems can develop, particularly in children with severe obstructive sleep apnoea or certain underlying medical conditions.

Seek emergency help if the child develops difficulty breathing, blue or grey lips, severe swelling, or unusual difficulty waking up.

How Can Parents Help Children Recover?

• Follow the surgeon's instructions, give prescribed pain relief on schedule, and encourage regular fluid intake.
• Offer a tonsillitis diet that includes soft foods that the child can tolerate, and allow sufficient rest.
• Avoid strenuous activity until the surgeon says it is safe, as this can help reduce the risk of bleeding.
• Children should also attend any recommended follow-up appointments.
• Recovery time varies, but many children need around 10 to 14 days before returning to school and normal activities.

When To Seek Urgent Medical Help?

Fresh bleeding, difficulty breathing, inability to swallow fluids, signs of significant dehydration, or unusual drowsiness should never be ignored.

Although tonsil removal can offer substantial benefits for children who need it, understanding the possible side effects helps parents prepare for recovery and recognise complications early.
