Acute appendicitis often hides behind ‘just a stomach ache’. As abdominal pain is a common symptom of everyday stomach or digestive issues, many people tend to overlook it at first. This delay of even a couple of days can strain an already inflamed appendix and make recovery more complex.
The characteristic sign of issues in the appendix is pain that starts centrally and migrates to the lower-right abdomen, as reported in about 80% of patients. Delays in diagnosis and treatment may lead to higher rates of complicated appendicitis and postoperative problems. That’s why a timely, structured assessment pathway is crucial to understand the issue associated with the organ.
What Is the Appendix?
The appendix is a small, blind-ended pouch attached to the large bowel in the lower-right abdomen. Understanding the condition of the appendix helps understand the source of pain: if its opening becomes blocked, the tissue swells, bacteria multiply, or any other issues. Appendicitis can develop quickly, turning local pain into a wider infection if care is delayed.
Understanding Its Role in the Body
Once labelled vestigial, i.e., without any known purpose, the appendix contains lymphoid tissue that is thought to support gut immunity, acting as a safe house for helpful bacteria that are useful after stomach infections or antibiotic courses.
- • The appendix is a small, tube-shaped pouch in the lower-right abdomen.
- • Rich in lymphoid tissue, it may support local immune responses.
- • Appendicitis occurs when this pouch becomes inflamed or infected.
Why is it an emergency?
Appendicitis can progress from local inflammation to eventual rupture and widespread infection. The longer the treatment is delayed, the greater the risk of complications, longer hospital stays, and prolonged recovery. Here are the key signs that necessitate immediate treatment:
- • >24 hours (Alert zone): Delays in recognising that it’s more than a stomach ache can cause further issues in smooth treatment.
- • ≥48 hours (Complication zone): Longer symptom duration is associated with higher rupture risk.
- • When rupture occurs: A ruptured appendix is a health emergency requiring immediate medical care. Once ruptured, the pus and bacteria spread to the surrounding large intestine tissue, with a significant risk of sepsis and other health issues.
Note: Structured assessment and imaging reduce missed diagnoses and cut negative appendicectomies to low single digits (e.g., ultrasound ~4.8%; adding CT ~0.6%).
What Causes Appendicitis?
Most cases begin when the opening of the appendix becomes blocked at its junction with the large intestine. As pressure builds, blood flow to the tissue decreases, and bacteria multiply, turning simple irritation into infection and, if untreated, eventually leading to perforation.
How does a blockage set off inflammation?
A physical blockage (e.g., appendicolith/faecolith or swollen lymph tissue) sets off a chain reaction from pressure to reduced blood flow. This pressure-and-blockage cycle explains why abdominal pain can intensify quickly.
- • When the opening of the appendix becomes blocked (Lumen obstructed), pressure builds up inside it (intraluminal pressure). This reduces the flow of blood to the tissue, irritating (venous outflow impairment). If it remains unattended, it damages the appendix wall (ischaemia).
- • Bacterial overgrowth intensifies inflammation and pain.
- • Without relief, wall necrosis and pressure buildup may lead to perforation/abscess.
Common triggers and risk factors
Different elements can block the appendix; some also raise the chance of a complicated disease. This is the day-to-day picture of what causes appendicitis in patients.
- • Appendicolith (faecolith): A small mass of hardened stool or digestive debris found in the appendix. It appears in about 39% of complicated cases compared with roughly 14% of uncomplicated ones. Prevalence on CT scans varies between studies, but its presence is linked to a higher risk of perforation.
- • Lymphoid hyperplasia: Swelling of immune tissue, more common in children and teenagers, which can narrow the appendix opening and block normal flow.
- • Infections: bacterial/viral; parasites (Schistosoma, Enterobius) can trigger or mimic appendicitis.
- • Neoplasms (rare): Appendiceal/caecal tumours causing obstruction.
- • Foreign bodies/trauma (uncommon): Occasionally, foreign material lodged in the lower abdomen (from internal/external injury) can trigger appendicitis.
- • Family history: Though there is no genetic link, appendicitis often gets associated with close relatives and their lifestyles.
Prevalence: Who Is at Risk?
Appendicitis can occur at any age, but awareness of the likelihood can help individuals and their families to notice the symptoms early. The risk of contracting appendicitis is slightly higher in case of certain groups; further, only a category of people faces higher complication risks. Here is a list and range of people most affected:
- • Lifetime risk: Around 8.6% in males and 6.7% in females.
- • Typical age group: Most cases occur between ages 10 and 20, though they can appear anywhere from 5 to 45 years.
- • Children under 5 years: More likely to present with a ruptured appendix (about 30–75%) due to delayed recognition.
- • Older adults: Also at higher risk of perforation and postoperative complications.
- • Pregnancy: Occurs in roughly 0.06–0.12% of pregnancies; delays can increase serious risks for the mother.
- • Family history: Having a close relative with appendicitis may double one’s risk.
Common Symptoms and Signs of Appendicitis
As the inflammation progresses, the vague early symptoms tend to get clearer and more sharply indicative of appendicitis. The trademark sign is pain that starts centrally (periumbilical/epigastric) and localises to the right-lower abdomen over 24 to 48 hours. This pain is accompanied by loss of appetite, nausea, and low-grade fever.
Early symptoms (first 24–48 hours)
In day-to-day terms, what are the signs of appendicitis at the outset? Patients often experience migrating pain plus stomach upset, with subtle signs of infection.
- • Dull, central pain that shifts to the right lower side (classic migration).
- • Loss of appetite, nausea ± one or two episodes of vomiting.
- • Low-grade fever and a preference to stay still; pain worsens with movement/cough.
Advanced or severe symptoms
When inflammation escalates, appendicitis symptoms become more localised, and systemic signs appear. These are your red flags to seek urgent care.
- • Constant right-lower-abdominal pain with marked tenderness/guarding or rebound.
- • Higher fever, persistent vomiting, or inability to tolerate oral intake.
- • Worsening pain on walking, coughing, or bumps in the road (“peritonism” features).
How Is Appendicitis Diagnosed?
Diagnosis of appendicitis blends bedside assessment with targeted tests. Physicians start with history and examination, then use blood/urine tests and imaging to confirm or exclude disease. To confirm the diagnosis, imaging plays a key role:
- • Ultrasound is radiation-free and commonly used for diagnosis.
- • CT offers the highest accuracy in detecting inflammation.
- • MRI is preferred when radiation needs to be avoided, such as in children or during pregnancy.
These steps help your physician understand the complete picture, covering what they observe during your examination and what imaging reveals inside the abdomen. Let’s look at each stage more closely.
Physical examination (what your clinician looks for)
When you are experiencing pain and visit a doctor, they will start gently examining the origin of the discomfort. Certain signs (peritoneal signs) and movement help them determine whether the appendix might be inflamed. These are the diagnostic tests that confirm the condition:
- • Dunphy’s sign: You may be asked to cough gently. If this causes sharp pain in the lower right side of your abdomen, it may suggest irritation from an inflamed appendix.
- • Rebound tenderness (Blumberg’s sign): The doctor presses lightly on the lower abdomen and then releases quickly. If the pain becomes worse when the pressure is released, it indicates inflammation inside the abdomen.
- • Rovsing’s sign: The doctor presses on the lower left side of your abdomen; if this triggers pain on the right, it may point to irritation near the appendix.
- • Psoas sign: You may be asked to lift your right leg while lying down. Pain during this movement can suggest that the appendix is inflamed and pressing against nearby muscles.
- • Obturator sign: Your physician may gently rotate your right leg inward while it is bent. If this causes discomfort, it can also indicate irritation around the appendix.
In addition to these, the doctor will look for guarding (if your abdominal muscles tighten in response to touch) and check for pain with movement or coughing. These signs suggest progress in inflammation.
Diagnostic Tests and Imaging
Blood tests often show raised white cell counts or C-reactive protein (CRP) levels. The choice of imaging depends on age, pregnancy status, and what’s available at the hospital.
- • Blood tests: These identify inflammation by elevation in the levels of white blood cells (WBC) and C-reactive protein (CRP). Urine tests rule out the possibility of infections or kidney stones.
- • Ultrasound: A simple, radiation-free scan that uses sound waves to show if the appendix is swollen or if it is surrounded by fluid. It’s safe for use during pregnancy.
- • CT scan (Computed Tomography): Offers a detailed view of the appendix and nearby organs, helping to highlight swelling, rupture, or abscess formation quickly and accurately.
- • MRI (Magnetic Resonance Imaging): Uses magnetic fields to generate clear images without radiation. Especially useful for children and pregnant women when an ultrasound report is unclear.
- • Clinical scoring systems: Tools such as Alvarado or AIR scores combine symptoms, signs, and test results to estimate the likelihood of appendicitis before imaging.
Treatment and Management
Once doctors suspect appendicitis, two main treatment options are considered: first surgery (appendicectomy) or, in some uncomplicated cases, antibiotics. The choice depends on the severity of symptoms, imaging findings, and individual health factors. When surgery is needed, most guidelines recommend a laparoscopic appendicectomy for faster recovery and fewer complications.
Appendicectomy (surgical removal)
Keyhole surgery is standard in many centres because recovery is usually faster and complications are often fewer than with open surgery. It has significant laparoscopic benefits, including lower wound infection rates, shorter hospital stays, and a quicker return to normal activity.
Non-operative management (antibiotics)
For select uncomplicated cases, antibiotics can resolve symptoms without immediate surgery. However, this avenue of treatment does not prevent the recurrence of appendicitis. Therefore, specialists may prescribe antibiotics to address the issue effectively. However, antibiotics may not be suitable for patients with suspected perforation/abscess, sepsis, or high risk from an appendicolith on imaging.
Recovery and aftercare
Most people start moving on the same day after laparoscopic surgery and return to light activities within one to two weeks. Recovery usually takes longer after an open surgery or in the case of a perforated appendix. Healing depends on gentle walking, proper wound care, and restraint on heavy lifting activity until cleared by your doctor.
When to See a Doctor?
Don’t “wait and see” with persistent or shifting abdominal pain. If symptoms align with appendicitis, prompt assessment (often via an appendicitis test) lowers the risk of complications and unnecessary surgery.
- • If pain worsens or doesn’t settle, seek urgent consultation.
- • Treat the classical pain migration as a red flag.
- • If fever signs, pain, persistent nausea, and/or any aggravated symptoms occur, go to emergency care at the earliest.

Conclusion
Appendicitis is a serious condition, but it can be treated effectively when recognised early. Watch out for abdominal pain, especially the one that moves from the centre to the right of the abdomen. Most diagnosis involves a physical examination, blood or urine tests, and imaging to confirm the cause and lay the treatment plan.
Prompt care helps prevent complications like peritonitis after ruptures. In case the symptoms worsen, you need to arrange an immediate consultation and assessment with the best general surgeons in Dubai for timely, expert care.
FAQs
1) How to relieve appendix pain?
Patients shouldn’t self-medicate to mask severe or migrating pain. Instead, they should seek urgent assessment with a medical professional to confirm or rule out appendicitis.
2) Will everyone feel pain in the same spot?
Not always. The position of the appendix can differ slightly from person to person, and pregnancy may also shift where pain appears. Doctors rely on physical examination and imaging to make an accurate diagnosis.
3) Can appendicitis be treated without surgery?
In some uncomplicated cases, antibiotics may help control infection under close medical supervision. However, many people still need an appendicectomy if symptoms continue or come back.
4) What is mistaken for appendicitis?
Certain digestive or urinary problems can cause similar pain and discomfort. Tests such as an ultrasound or CT scan help confirm the true cause and guide treatment safely.
5) What causes appendicitis to occur suddenly?
It usually happens when the opening of the appendix becomes blocked, causing swelling and bacterial growth. This leads to inflammation and pain that can develop quite quickly.
6) What if the appendix bursts?
Rupture can cause peritonitis or abscess, leading to a higher complication risk and longer recovery. Patients should opt for prompt diagnosis and treatment before rupture to reduce these risks.
7) What happens when you get your appendix removed?
In case of both surgeries, keyhole (laparoscopic) or open, most people recover within 2–4
