Appendicitis: Causes, Symptoms, and Complications

Appendicitis is the inflammation of the appendix, a small pouch attached to the large intestine. It is considered a medical emergency and usually requires surgical removal. If left untreated, the appendix can rupture, leading to severe complications. Early identification of symptoms—such as pain in the lower right abdomen, fever, and nausea—is crucial. With timely intervention, recovery is smooth. Health insurance plans from Bajaj Allianz General Insurance Company can cover diagnosis and surgery at any of their 18,400+ partner hospitals, ensuring access to prompt and expert treatment.

What is Appendicitis?

Appendicitis occurs when the appendix becomes inflamed due to blockage or infection. This condition can lead to swelling, pain, and in severe cases, rupture. It most commonly affects people between the ages of 10 and 30, though it can happen at any age. Surgery is the standard treatment to remove the inflamed appendix (appendectomy). Recognising signs of appendix problems early and seeking timely medical care is essential to avoid life-threatening complications.

Stages of Appendicitis

Appendicitis typically progresses through several stages:

1. Early/Acute Stage: Inflammation begins with abdominal pain near the navel.
2. Suppurative Stage: The pain localises to the lower right side and becomes intense; pus may form.
3. Gangrenous Stage: Blood supply to the appendix is compromised, causing tissue death.
4. Perforated Stage: The appendix ruptures, spilling infectious material into the abdomen.

Each stage increases in severity and risk. Early diagnosis and treatment can stop the disease from progressing, significantly reducing the risk of appendicitis complications.

Early Signs and Symptoms of Appendicitis

Appendicitis symptoms often start suddenly and worsen quickly. Common signs include:

• Abdominal pain
• Loss of appetite
• Nausea or vomiting
• Low-grade fever
• Swelling in the abdomen
• Constipation or diarrhoea
• Inability to pass gas

The pain usually intensifies over time and may worsen when walking or coughing. In children and elderly patients, symptoms might be less predictable, making prompt medical evaluation essential. Identifying these early signs of appendix problems and seeking immediate care can prevent further complications.

Causes of Appendicitis

Appendicitis is typically caused by blockage of the appendix, which leads to infection. Common causes include:

• Fecaliths: Hard stool particles obstructing the appendix opening
• Lymphoid hyperplasia: Swelling of lymph tissue in response to infection
• Foreign bodies or parasites
• Tumours: Rare, but can obstruct the appendix
• Digestive tract infections: Can inflame intestinal tissues

Once blocked, bacteria multiply rapidly inside the appendix, triggering inflammation, swelling, and, if untreated, rupture.

Appendicitis Risk Factors

Certain factors may increase the likelihood of developing appendicitis:

• Age: Most common in people aged 10–30
• Gender: Slightly more frequent in males
• Family history: Genetic predisposition can play a role
• Diet low in fibre: May contribute to constipation and blockages
• Frequent gastrointestinal infections: Can inflame lymphatic tissue
• Immune disorders: May alter response to infections

While these don’t guarantee you’ll develop appendicitis, awareness of risk factors helps with quicker identification and preventive monitoring.

Diagnosis and Treatment Options for Appendicitis

Diagnosis typically involves a physical examination, blood tests (to check for infection), and imaging such as ultrasound or CT scans. Treatment almost always involves surgical removal of the appendix (appendectomy), either through open surgery or laparoscopic methods. Antibiotics may be given before surgery to manage infection. Health insurance from Bajaj Allianz General Insurance Company helps cover diagnostics, surgery, and hospitalisation.

Complications Arising from Untreated Appendicitis

If left untreated, appendicitis can cause:

• Rupture of the appendix, leading to widespread abdominal infection (peritonitis)
• Abscess formation around the ruptured area
• Sepsis, a life-threatening response to infection
• Intestinal blockage due to inflammation and scar tissue

These appendicitis complications can become severe quickly, so timely surgery is critical for patient safety.

Preventive Measures and Lifestyle Modifications

While appendicitis isn’t always preventable, a few measures may help reduce the risk:

• Eat a high-fibre diet with fruits, vegetables, and whole grains
• Stay hydrated to promote smooth digestion
• Manage infections promptly
• Avoid excessive junk food intake

Although no guaranteed prevention exists, healthy digestive habits can lower the likelihood of inflammation or blockage.
