What is appendicitis?
Appendicitis is inflammation of the appendix, a small pouch attached to the large intestine. It often occurs when the appendix becomes blocked, leading to infection and swelling. Untreated, it can rupture — a serious complication — so it is usually treated as a surgical emergency.
Common symptoms
- Pain that often starts around the navel and moves to the lower right abdomen
- Pain that worsens with movement, coughing or pressing
- Loss of appetite, nausea or vomiting
- Low-grade fever
- Abdominal tenderness and bloating
Diagnosis
A doctor will assess your symptoms and examine your abdomen, often supported by blood tests and imaging such as ultrasound or CT. Prompt assessment matters because symptoms can overlap with other abdominal conditions.
Treatment
The standard treatment is surgical removal of the appendix (appendicectomy), most commonly performed laparoscopically (keyhole surgery) with small incisions, a shorter recovery and less scarring. In selected early cases, antibiotics may be considered, but surgery remains the definitive treatment for most people.
When to seek care
Sudden, worsening abdominal pain — especially in the lower right side with fever or vomiting — should be assessed urgently. If pain becomes severe or you feel very unwell, seek emergency care.
