Risks and benefits of appendicectomy

Overview

Appendicectomy is surgery to remove the appendix. The appendix is a small, finger-like pouch attached to the large intestine. Surgeons usually do this operation when the appendix becomes swollen and infected (a condition called appendicitis). Removing the appendix stops the infection from spreading and helps you get better.

Yes, appendicectomy is very common. Appendicitis affects about 1 in 10 people, and most of them will need surgery to remove the appendix.

Appendicitis can happen at any age, but it is most common in people between 10 and 30 years old. It affects both men and women.

Symptoms

Common symptoms

• Pain that starts near your belly button and then moves to the lower right side of your abdomen
• Loss of appetite
• Nausea or vomiting
• A low fever (around 37.5–38.5°C)
• Swelling or tenderness in your lower right belly
• Feeling bloated or unable to pass gas

Symptoms in children

• Young children may not be able to describe the pain clearly; they might just seem irritable or fussy
• Vomiting comes before the pain starts
• They may have a fever and refuse to eat
• Pain might affect the whole belly rather than just one side

Symptoms in older adults

• Pain may be less severe and harder to pinpoint
• Symptoms such as confusion, nausea, and a general feeling of being unwell can be more noticeable
• Fever might be absent or low-grade
• Bowel changes like constipation or bloating can occur

Causes

Main causes

• The most common cause is a blockage at the opening of the appendix. This can happen when hard stool, a swollen lymph node, or an infection blocks the tiny tube.
• When the appendix is blocked, bacteria can multiply and cause inflammation, swelling, and pus. This is appendicitis.

Risk factors

• Age – it is most common in teenagers and young adults
• Having a family history of appendicitis
• A low-fibre diet may increase risk, though the evidence is not strong

When to see a doctor

See a doctor urgently if:

• If you have constant pain in the lower right side of your belly that lasts more than a few hours
• If the pain gets worse when you move, cough, or sneeze
• If you have a fever along with belly pain

Book a routine appointment if:

• If you have mild belly pain that comes and goes but lasts more than a day
• If you have unexplained nausea or loss of appetite that continues

Diagnosis

Doctors diagnose appendicitis by listening to your symptoms, doing a physical exam, and often running tests. The diagnosis is usually made quickly once you are in hospital.

Tests that may be done

• A physical exam where the doctor presses gently on your belly to check for tenderness and swelling
• Blood tests to look for signs of infection (high white blood cell count)
• An ultrasound or CT scan to see if your appendix is swollen or inflamed

What to expect at your appointment

If your doctor suspects appendicitis, they will likely send you to a hospital for further checks. You may have a scan and blood tests. The whole process usually takes a few hours. If the diagnosis is clear, the surgical team will talk to you about having the operation soon — often within hours.

Treatment

The main treatment for appendicitis is surgery to remove the appendix. In some mild cases, doctors may try antibiotics first, but surgery is the standard and safest option. Once the appendix is removed, the infection cannot come back.

Self-care at home

• Do not eat or drink if you think you might have appendicitis — surgery may be needed soon
• Do not take laxatives or painkillers without a doctor’s advice, as they can mask symptoms or make things worse
• After surgery, follow your surgeon’s advice on wound care, gentle movement, and when you can shower

Medical treatments

If appendicitis is caught very early and is mild, some people may be treated with antibiotics alone. This avoids surgery but carries a risk of the infection returning. Your doctor will discuss the options based on your specific case. For most people, surgery remains the recommended treatment.

When is surgery considered?

Surgery is usually done as soon as possible once appendicitis is diagnosed. Waiting too long raises the risk of the appendix bursting (rupturing). The operation is done under general anaesthetic (you are asleep) and takes about 30 to 60 minutes.

Living with this condition

After an appendicectomy, most people go home within 1 to 3 days if the appendix was not burst. If it had already burst, you may need to stay a bit longer. For the first week, you will feel tired and sore. Rest, drink plenty of fluids, and take pain relief as recommended by your healthcare team. Avoid heavy lifting and intense exercise for 4 to 6 weeks.

Lifestyle tips

• Gradually return to normal activities as you feel able — listen to your body
• Wound care: keep the area clean and dry. Check for signs of infection (redness, oozing, fever)
• Avoid driving for at least a week or until you can press the pedals without pain and turn quickly
• Talk to your employer about time off — desk jobs often need 1–2 weeks, physical jobs up to 4 weeks

Diet and exercise

Start with light, easy-to-digest foods like soup, toast, and rice. Avoid heavy, fatty meals for the first few days. Gentle walking is good for recovery and blood flow. Do not do sit-ups or heavy lifting until your surgeon says it is safe.

Mental health and emotional wellbeing

Having emergency surgery can be upsetting and anxiety-provoking. It is normal to feel worried or low afterwards. Talk to your doctor or a counsellor if you feel overwhelmed. You can also speak with the hospital’s psychology team if available.

Prevention

There is no sure way to prevent appendicitis. Eating a high-fibre diet with plenty of fruits, vegetables, and whole grains may help reduce the risk, but the evidence is not strong. Most cases happen without a clear reason.

Complications

If left untreated

• The appendix can burst (rupture), spilling infection into your belly cavity
• This can cause a serious infection called peritonitis
• An abscess (collection of pus) may form around the appendix
• If the infection spreads to the bloodstream, it can lead to sepsis, which is life-threatening

Long-term outlook

If treated quickly, the outlook after an appendicectomy is excellent. Most people recover fully without any long-term problems. Even if the appendix bursts, modern surgery and antibiotics give very good results. Your body works perfectly fine without an appendix, and you can return to all your normal activities within a few weeks.
