What is Appendicitis?

Appendicitis is the acute inflammation of the appendix, a small finger-shaped pouch attached to the large intestine, most commonly caused by an obstruction that leads to bacterial overgrowth, swelling, and infection within the appendix wall. It is one of the most common causes of emergency abdominal surgery worldwide and can affect people of any age, though it is most frequent in adolescents and young adults. If untreated, the inflamed appendix can rupture, spilling infected contents into the abdominal cavity and causing potentially life-threatening peritonitis. Prompt recognition and treatment are essential to prevent this complication.

What are the main symptoms of Appendicitis?

The most common symptoms include: Sudden pain starting near the navel that migrates to the lower right abdomen; loss of appetite; nausea and vomiting; low-grade fever. Early recognition is key to prompt diagnosis and effective treatment.

Is Appendicitis contagious?

No, Appendicitis is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

How is Appendicitis treated?

Treatment options include: Surgical removal of the appendix; known as appendectomy; performed either laparoscopically or through open surgery. Treatment should always be guided by a qualified General Surgery specialist. Do not self-medicate.

Can Appendicitis be prevented?

While Appendicitis cannot always be fully prevented, several measures can reduce risk: No proven method fully prevents appendicitis; though a high-fiber diet rich in fruits and vegetables may modestly reduce risk; prompt medical evaluation of persistent abdominal pain.

When should I see a doctor for Appendicitis?

Seek immediate medical attention if you experience symptoms of Appendicitis. This is a serious condition — go to the emergency room or call 112 if symptoms are severe or rapidly worsening.
