A tonsillectomy is one of the most common surgical procedures performed on children in the UK. While it is generally a safe and routine operation, like any surgery, it carries specific risks that parents must be aware of. In the UK, the decision to proceed with a tonsillectomy is only made when the benefits, such as stopping recurrent infections or treating sleep apnoea, outweigh these potential complications. Most children recover fully within two weeks, but understanding the possible hurdles during that time is essential for a safe recovery at home.
The risks can be broadly categorised into those that occur during the operation and those that happen during the recovery phase. UK clinical teams provide extensive support and information to families to help them identify red flags early. By knowing what is normal and what requires medical attention, parents can manage their child recovery with confidence.

Common recovery challenges
The most frequent risk associated with a tonsillectomy is not a complication but a side effect of the healing process. Pain is the primary challenge for children. Unlike other surgeries, the surgical site is in the throat, which means every swallow can be uncomfortable.
Common issues include:
- Severe Throat Pain: This can last for up to 10 to 14 days and often gets worse around day 4 or 5 before it improves.
- Earache: This is referred pain from the throat and does not usually mean there is an ear infection.
- Dehydration: Because swallowing is painful, children may refuse to drink. In the UK, this is a common reason for readmission to hospital for intravenous fluids.
The risk of bleeding
Bleeding is the most significant clinical risk of a tonsillectomy. UK surgeons categorise this into two types:
- Primary Haemorrhage: This occurs within the first 24 hours of surgery. It is rare and usually happens while the child is still under observation in the hospital.
- Secondary Haemorrhage: This occurs between 5 and 10 days after surgery. It is often caused by the protective scab at the back of the throat falling off or a minor infection at the site.
Anaesthesia and infection risks
All tonsillectomies in the UK are performed under general anaesthesia. While modern anaesthesia is very safe for children, there is a very small risk of allergic reactions or breathing difficulties during the procedure. The surgical team includes specialist paediatric anaesthetists to manage these risks.
Infection at the surgical site is another possibility. While the back of the throat will naturally look white or yellow as it heals, a true infection may cause:
- A high fever that does not come down with paracetamol.
- Foul smelling breath that is worse than typical post operative odour.
- Increased pain and a general feeling of being very unwell.
Comparison: Normal Recovery vs Surgical Complications
| Feature | Normal Post Op Recovery | Potential Complication |
| Throat Appearance | White or yellow coating scabs | Fresh red blood or active oozing |
| Pain Level | Managed with regular meds | Unbearable or worsening fever |
| Fluids | Sips possible despite discomfort | Refusal to drink leading to dehydration |
| Breath | Mildly unpleasant surgery smell | Extremely foul or putrid odour |
| Temperature | Slight rise for 24 hours | High fever after the first day |
| UK Action | Continue home care and meds | Contact GP or attend A and E |
To Summarise
While tonsillectomy is a standard procedure in the UK, it involves risks such as post operative bleeding, pain, and dehydration. Most of these risks are manageable with proactive home care and regular pain relief. By ensuring your child drinks plenty of fluids and follows the medication schedule provided by the hospital, you can significantly reduce the likelihood of complications. Understanding the difference between the normal healing process and emergency red flags like fresh bleeding ensures that your child receives the safest possible care.
If you notice any fresh red bleeding from your child mouth or nose, call 999 or go to your local emergency department immediately.
How common is bleeding after tonsillectomy in children?
In the UK, significant bleeding occurs in approximately 2 to 5 percent of children. Most cases are minor, but all require an urgent medical review to ensure safety.
Will my child need to stay in hospital overnight?
Many tonsillectomies in the UK are now performed as day cases, meaning your child can go home the same day if they are eating, drinking, and have no signs of bleeding.
Does a tonsillectomy change a child voice?
Initially, the voice may sound different due to swelling and the extra space in the throat. As the area heals, the voice usually returns to normal, though it may sound slightly higher or clearer.
Is there a risk to the immune system?
The tonsils are part of the immune system, but the body has hundreds of other lymph nodes that perform the same job. Long term UK studies show no increase in general infections after tonsil removal.
What is the best way to prevent bleeding?
Encouraging your child to eat a normal, relatively rough diet like toast or cereal as soon as they can helps to keep the surgical site clean and prevents thick scabs from building up.
Why does the pain get worse after a few days?
This is often when the protective scabs start to come away. In the UK, doctors advise parents to stay on top of the pain relief schedule even if the child seems to be feeling better on day two or three.
