Appendicitis

Gambaran keseluruhan

Appendicitis is inflammation (swelling and irritation) of the appendix — a small, finger-shaped pouch attached to the large intestine in the lower right side of your abdomen (belly). When the appendix becomes blocked and infected, it swells up and causes pain. If it is not treated quickly, it can burst, which is a medical emergency. The good news is that appendicitis is very treatable, and most people recover fully with prompt care.

Yes, appendicitis is quite common. Around 1 in 13 people will develop appendicitis at some point in their life, making it one of the most frequent surgical emergencies seen in hospitals around the world.

Appendicitis can affect anyone at any age, including young children and older adults. It is slightly more common in males than females and most often strikes teenagers and young adults in their teens and twenties, though no age group is immune.

Gejala

Gejala biasa

• Pain that starts around the belly button and then moves to the lower right side of the abdomen — this is the most classic sign.
• Pain that gets steadily worse over a few hours and feels sharper when you move, cough, or take a deep breath.
• Loss of appetite — not feeling like eating.
• Nausea (feeling sick to your stomach) and sometimes vomiting.
• Low-grade fever (a slightly raised temperature, usually between 37.5°C and 38.5°C / 99.5°F and 101.3°F).
• Feeling bloated or having an upset, uneasy feeling in the abdomen.
• Constipation (difficulty passing stools) or, less often, diarrhoea.

Gejala pada kanak-kanak

• Young children, especially those under 5, may not be able to describe their pain clearly — they may just seem unwell, irritable, or unusually quiet.
• Pain may be more generalised (spread across the whole belly) rather than in one spot.
• Vomiting and fever may be more prominent symptoms than pain in young children.
• Children may walk bent over or refuse to stand up straight because movement worsens the pain.
• Appendicitis in young children progresses (gets worse) faster than in adults, so seeking care quickly is especially important.

Gejala pada orang dewasa yang lebih tua

• Older adults often have milder or less typical symptoms, which can make appendicitis harder to spot.
• The classic pain may be less intense or in a slightly different location.
• Fever may be lower or even absent, despite a serious infection.
• Confusion or feeling generally unwell may be early signs rather than obvious belly pain.
• Because symptoms can be subtle, the appendix is more likely to have already burst by the time older adults seek care — making it especially important not to delay.

Punca

Punca utama

• Blockage inside the appendix — most commonly caused by hardened stool (a small, hard piece of faeces) becoming lodged inside it.
• A build-up of mucus inside the appendix that causes the walls to swell.
• Swollen lymph nodes (small infection-fighting glands) in the wall of the appendix, often following a stomach bug or infection elsewhere in the body.
• Rarely, a small growth, parasite, or foreign material can cause a blockage.
• Once blocked, bacteria multiply rapidly inside the appendix, causing infection and dangerous swelling.

Faktor risiko

• Age — teenagers and young adults are at highest risk, though anyone can be affected.
• Sex — males have a slightly higher lifetime risk than females.
• Family history — having a close family member who has had appendicitis may slightly increase your risk.
• A diet low in fibre — some research suggests this may contribute to the types of blockages that can trigger appendicitis, though the evidence is not definitive.
• Gastrointestinal infections — certain stomach or intestinal infections may increase the risk.

Bila perlu berjumpa doktor

Jumpa doktor dengan segera jika:

• Any abdominal pain that is worsening over a few hours, especially if it settles in the lower right side.
• Abdominal pain accompanied by fever, nausea, or vomiting.
• Pain that is severe enough to interfere with normal movement or walking.
• Symptoms in a child that seem to be getting rapidly worse.
• If you are pregnant and have abdominal pain — the position of the appendix shifts during pregnancy, so symptoms may feel different. Always seek prompt care.

Buat temujanji rutin jika:

• Mild, occasional stomach aches that come and go without fever or other symptoms are unlikely to be appendicitis, but it is always okay to check in with your doctor if something feels off.
• If you have had previous episodes of right-sided abdominal pain that resolved on their own, mention this to your GP (general practitioner, your regular family doctor) at your next visit.

Diagnosis

Diagnosing appendicitis involves a combination of listening carefully to your symptoms, a physical examination, and some tests. There is no single test that is 100% definitive on its own, so doctors use all the information together to make their decision. The process is usually straightforward and happens relatively quickly in hospital.

Ujian yang mungkin dilakukan

• Physical examination — a doctor will gently press on your abdomen to check where the pain is worst and whether the area feels hard or tender.
• Blood tests — a full blood count (checking the number of white blood cells, which go up when there is infection or inflammation) is a key test.
• Urine test — to rule out a urinary tract infection (a bladder or kidney infection), which can cause similar symptoms.
• Ultrasound scan — sound waves are used to create a picture of the inside of your abdomen. It is safe, painless, and does not use radiation. It is particularly useful in children and pregnant women.
• CT scan (computed tomography) — a detailed X-ray that gives a very clear picture of the appendix and surrounding area. It is highly accurate and commonly used in adults when the diagnosis is uncertain.
• MRI scan (magnetic resonance imaging) — may be used instead of CT in some situations, particularly in pregnant women, as it does not use radiation.
• Diagnostic laparoscopy — in some cases, a surgeon may need to look directly inside the abdomen using a tiny camera through a small incision (cut) to confirm the diagnosis.

Apa yang diharapkan semasa temujanji anda

When you arrive at hospital with suspected appendicitis, things tend to move fairly quickly. You will be asked about your symptoms, have a physical exam, and be sent for blood tests and imaging fairly promptly. You may be asked not to eat or drink while the team investigates, in case you need surgery. The team will keep you informed at each step. While waiting for results can feel stressful, the staff are focused on getting you the right answer as quickly as possible.

Rawatan

Appendicitis is treated in hospital. The most common and well-established treatment is surgery to remove the appendix — a procedure called an appendicectomy (also called appendectomy). In some carefully selected cases of uncomplicated appendicitis (where the appendix has not burst), doctors may try treating the infection with antibiotics first and monitor closely to see if surgery can be avoided. Your surgical team will discuss the best option for your individual situation.

Penjagaan diri di rumah

• Do NOT take pain-relieving medicines, laxatives, or apply heat to your belly while waiting for medical assessment — these could mask symptoms and delay diagnosis.
• Do not eat or drink anything once you suspect appendicitis, as you may need an anaesthetic (medicine to put you to sleep) for surgery very soon.
• Rest and try to stay as still and comfortable as possible while travelling to hospital or waiting to be seen.
• After treatment and discharge from hospital, follow your surgical team's instructions carefully about rest and wound care.
• Avoid strenuous activities and heavy lifting during your recovery period as advised by your care team.

Rawatan perubatan

Treatment falls into two main approaches. The first and most common is surgery. An appendicectomy — the removal of the appendix — can be done as keyhole surgery (laparoscopic surgery, using small cuts and a tiny camera) or, less often, as open surgery (a single larger cut). Keyhole surgery is now standard in most hospitals and usually means a shorter recovery time. The second approach, used in selected cases of uncomplicated appendicitis, involves a course of intravenous antibiotics (antibiotics given directly into a vein in hospital) to clear the infection without immediate surgery, followed by close monitoring. If antibiotics are chosen, it is important to know that surgery may still be needed later. If the appendix has already burst (ruptured), surgery is always needed, and treatment may also involve draining any collection of pus (an abscess) that has formed. Antibiotics are used alongside surgery to treat infection.

Bila pembedahan dipertimbangkan?

Surgery is recommended for most people with appendicitis and is always necessary if the appendix has burst or is about to burst, if there are signs of a serious spreading infection (called peritonitis — infection of the lining of the abdomen), or if antibiotic treatment has not worked. Your surgical team will explain which approach is best for you based on the severity of your condition, your overall health, and your personal preferences.

Hidup dengan keadaan ini

Recovery from appendicitis, once treated, is generally very good. After keyhole surgery, most people feel well enough to return to light activities within one to two weeks. Recovery after open surgery typically takes two to four weeks. You may feel tired and have some soreness around your wound for a while — this is completely normal. Most people return to full normal life, including work and exercise, within a few weeks. Since the appendix has no essential function in adults, its removal has no long-term impact on your digestive health or quality of life.

Tip gaya hidup

• Follow your surgical team's specific advice about when it is safe to return to work — this depends on the type of surgery you had and the nature of your job.
• Avoid heavy lifting and strenuous exercise until your surgeon gives you the all-clear, usually after a follow-up appointment.
• Keep your surgical wound clean and dry as instructed. Watch for any signs of infection such as increasing redness, warmth, swelling, or discharge from the wound.
• Gradually increase your activity levels day by day — short, gentle walks are a great starting point.
• Do not drive until you are able to perform an emergency stop without discomfort, and always check with your care team.

Diet dan senaman

There are no special long-term dietary restrictions after having your appendix removed. In the first few days after surgery, you may find it easier to stick to light, easy-to-digest foods and to drink plenty of fluids. As your appetite returns and your gut recovers from the anaesthetic, you can gradually return to your normal diet. Eating a balanced diet with plenty of fruits, vegetables, and fibre is always good for digestive health. Exercise should be reintroduced gently — start with short walks and build up gradually, guided by how you feel and your surgeon's advice.

Kesihatan mental dan kesejahteraan emosi

It is normal to feel shaken, anxious, or even a little low after a sudden health scare and an operation. Some people feel frustrated by the recovery period, especially if they are used to being active. Allow yourself time to heal both physically and emotionally. If feelings of anxiety, low mood, or worry about your health persist for more than a couple of weeks after recovery, do speak to your GP or a mental health professional. You do not have to manage these feelings alone. If you are ever in emotional distress, please reach out to a crisis support service in your area.

Pencegahan

There is currently no reliable way to prevent appendicitis entirely, as it often happens due to factors beyond our control. Some research suggests that a diet rich in fibre — found in fruits, vegetables, whole grains, and pulses — may help maintain healthy bowel function and could potentially lower risk, though this has not been proven definitively. Staying well hydrated and generally looking after your gut health is always a good idea, even if it cannot guarantee prevention.

Vaksin

There is no vaccine available to prevent appendicitis.

Program saringan

There is no routine screening programme for appendicitis. Because it develops suddenly and unpredictably, the focus is on recognising symptoms early and seeking prompt medical care rather than screening.

Komplikasi

Jika tidak dirawat

• Rupture (the appendix bursting) — if appendicitis is not treated, the appendix can burst, usually within 24 to 72 hours of symptoms starting. This is a medical emergency.
• Peritonitis — when a burst appendix releases bacteria into the abdominal cavity (the space inside your belly), causing a serious infection of the lining of the abdomen. This requires emergency surgery and intensive treatment.
• Abscess formation — a pocket of infection (pus) can form in the abdomen after a rupture. This may need to be drained with a needle guided by imaging, or surgically.
• Sepsis — in severe cases, infection can spread into the bloodstream (called sepsis or blood poisoning), which is a life-threatening condition requiring urgent intensive care.
• Bowel obstruction — in rare cases, scar tissue (adhesions) that forms after peritonitis can cause blockages in the bowel later in life.

Pandangan jangka panjang

The outlook for appendicitis is genuinely very good when it is caught and treated promptly. The vast majority of people who have their appendix removed make a full and complete recovery and go on to live normal, healthy lives. Even in cases where the appendix has already burst, modern surgery and care mean that most people recover well with appropriate treatment. The key is not to delay — the sooner you seek help when symptoms develop, the smoother and faster your recovery is likely to be.
