Appendicitis is a condition in which the appendix becomes inflamed and swollen. The appendix is a small, finger-shaped pouch attached to the lower right part of the large intestine. Although it is not essential for survival, its inflammation can quickly become dangerous if not treated in time.
Appendicitis usually occurs when the appendix becomes blocked by hardened stool, swollen lymphatic tissue or infection. Bacteria multiply inside the blocked appendix, causing swelling, reduced blood flow and tissue damage. If untreated, the appendix may rupture and spread infection into the abdominal cavity. For this reason, appendicitis is considered a medical emergency.
It most commonly affects people between 10 and 30 years of age, but it can occur at any age.
Signs and Symptoms
Early recognition is very important. Typical symptoms include:
• Pain that begins near the belly button
• Pain that moves to the lower right abdomen
• Increasing abdominal pain
• Nausea and vomiting
• Loss of appetite
Other possible symptoms may include:
• Fever
• Abdominal tenderness
• Pain that worsens with movement or coughing
• Bloating
• Constipation or, in some cases, diarrhea
Children, elderly individuals and pregnant women may not have typical symptoms. If the appendix ruptures, severe abdominal pain, high fever and signs of widespread infection may develop. This requires immediate emergency care.
Diagnosis
A healthcare provider evaluates symptoms, performs a physical examination and may order tests such as:
• CT scan
These help confirm appendicitis and rule out other conditions.
Treatment
Appendicitis requires urgent treatment.
Antibiotics are given to treat and prevent infection. In very early and mild cases, antibiotics alone may temporarily improve symptoms, but recurrence is common.
Surgery (appendectomy) is the standard and most reliable treatment. The appendix is usually removed within 24 hours of diagnosis to prevent rupture. Most surgeries are performed laparoscopically, allowing faster recovery. In complicated cases, open surgery may be necessary. The appendix is not a vital organ, and people live normal lives after its removal.
Complications and Recovery
If untreated, appendicitis may lead to rupture, abscess, peritonitis or sepsis. Early treatment greatly reduces these risks. Most patients recover completely, especially with early care. After uncomplicated surgery, many return home within 24 hours and fully recover within several weeks. Seek immediate medical attention if you experience persistent or worsening pain in the lower right abdomen, especially with fever, nausea or vomiting.
