Preparing for appendicectomy

Overview

An appendicectomy (say: ap-en-dih-SEK-toh-mee) is surgery to remove the appendix. The appendix is a small, finger-shaped pouch at the start of your large intestine. Usually, the operation is done when the appendix becomes inflamed and infected, a condition called appendicitis. Removing it stops the infection from spreading and helps you get better.

Yes, appendicectomy is a very common operation. Thousands of people have it every year in the UK.

Appendicitis can happen at any age, but it is most common in people between the ages of 10 and 30. It affects both men and women, though slightly more men get it.

Symptoms

Common symptoms

• Pain that starts near the belly button and moves to the lower right side of the abdomen (tummy)
• Nausea and sometimes vomiting
• Loss of appetite
• A mild fever (temperature around 37.5–38.5°C)
• Swelling or tenderness in the lower right abdomen
• Feeling generally unwell or tired

Symptoms in children

• Pain that may be higher up in the abdomen or more spread out
• Crying, fussiness, or being very quiet
• Not wanting to eat or play
• Vomiting and fever may come earlier than in adults

Symptoms in older adults

• Pain may be less intense or in a different spot, making it harder to spot
• Mild tenderness that is easy to ignore
• Constipation or bloating
• Fever may be less common or lower
• Feeling confused or more tired than usual

Causes

Main causes

• A blockage inside the appendix, often by a small piece of stool, a swollen lymph node, or occasionally a benign growth
• An infection or inflammation that spreads from elsewhere in the digestive tract

Risk factors

• Being a young adult (especially between 10 and 30)
• Having a family history of appendicitis (though this is not common)
• Having a condition that causes low fibre intake (though evidence is not strong)

When to see a doctor

See a doctor urgently if:

• If you have stomach pain that does not go away for more than 4–6 hours
• If the pain moves to the lower right side
• If you have a fever along with abdominal pain
• If you are vomiting and cannot keep fluids down

Book a routine appointment if:

• If you have mild, occasional stomach discomfort that you are worried about
• If you have recovered from appendicitis without surgery but want to discuss your risk in the future

Diagnosis

Doctors will ask about your symptoms and do a physical exam, including gently pressing on your abdomen. They may also run tests to confirm appendicitis and rule out other problems.

Tests that may be done

• Blood test to look for signs of infection (high white blood cell count)
• Urine test to check for a urinary tract infection or kidney stones
• Ultrasound scan (uses sound waves to create images of your organs)
• CT scan (a special X-ray that gives detailed pictures) – sometimes used if the diagnosis is not clear

What to expect at your appointment

You will likely be admitted to hospital. If appendicitis is confirmed, surgery is usually done within a few hours to prevent the appendix from bursting. The medical team will explain everything, answer your questions, and help you prepare for the operation.

Treatment

The main treatment for appendicitis is surgery to remove the appendix. In some mild cases without complications, antibiotics alone may be tried first, but surgery is the most common and reliable way to fix the problem. Your surgeon will discuss the best option for you.

Self-care at home

• Do NOT eat or drink anything if you suspect appendicitis – this is important in case you need surgery soon
• Do NOT take laxatives or enemas, as they can increase the risk of rupture
• Do not take painkillers that hide symptoms (like strong opioids) without medical advice
• Apply a cold pack or warm compress to the abdomen only if your doctor says it is safe
• Rest and avoid strenuous activity until you see a doctor

Medical treatments

If you have uncomplicated appendicitis (no rupture, abscess, or widespread infection), your doctor may offer a course of intravenous antibiotics first. This involves staying in hospital for antibiotics given through a vein in your arm. If this does not work, or if signs worsen, surgery will still be needed. Surgery itself can be done as a minimally invasive procedure (laparoscopic, using small cuts and a camera) or as an open operation (a larger cut in the lower right abdomen). Your surgeon will explain which method is best for you, depending on your health and how bad the inflammation is.

When is surgery considered?

Surgery is recommended as soon as possible after diagnosis, usually within 24 hours. If the appendix has already burst (perforated), emergency surgery is needed immediately to clean the infection and remove the appendix.

Living with this condition

After an appendicectomy, most people start to feel better within a few days. You can usually go home 1–2 days after keyhole surgery, or 3–5 days after open surgery. You will need to take it easy for 1–2 weeks (keyhole) or 4–6 weeks (open) before returning to normal activities, including work and exercise.

Lifestyle tips

• Avoid heavy lifting (more than a few kilograms) for 4–6 weeks after open surgery or 2–3 weeks after keyhole surgery
• Do not drive for at least 1–2 weeks, or until you can stomp your foot down hard in an emergency without pain
• Ask your doctor when it is safe to resume sports, sex, and other activities
• Keep the wound clean and dry until it heals – your nurse will show you how to change the dressing

Diet and exercise

You can start drinking clear fluids a few hours after surgery, then move to light foods like toast, rice, soup, and yoghurt. Eat small, frequent meals to avoid bloating. Stop if you feel nauseous. Gentle walking is encouraged as soon as you feel able – it helps blood flow and recovery. Avoid running, swimming, or heavy gym until your doctor says yes.

Mental health and emotional wellbeing

An emergency surgery can be scary and stressful. It is normal to feel anxious, worried, or a bit down afterwards. Many people feel better within a few weeks, but if low mood or anxiety lasts, talk to your GP or a hospital counsellor. You can also call a mental health helpline for support.

Prevention

There is no proven way to prevent appendicitis or the need for appendicectomy. Eating a high‑fibre diet might slightly reduce the risk of a blockage, but it is not guaranteed. The best thing you can do is recognise symptoms early and seek medical help quickly – this lowers the chance of your appendix bursting and makes recovery easier.

Vaccines

No vaccine prevents appendicitis.

Screening programmes

There is no routine screening for appendicitis. If you have symptoms, your doctor will evaluate you individually.

Complications

If left untreated

• The appendix can burst (perforate), letting infection spread into the abdomen, a serious condition called peritonitis
• An abscess (a pocket of pus) may form in the abdomen, needing drainage with a needle or further surgery
• Sepsis (a severe infection spreading through the blood) – this is life‑threatening and requires emergency hospital care

Long-term outlook

With prompt treatment, almost everyone makes a full recovery from appendicitis. Even after a burst appendix, most people get better with hospital care and antibiotics. The outlook is excellent – you can live a normal, healthy life without your appendix.
