Appendicitis is a medical condition in which the appendix becomes inflamed and swollen. The appendix is a small, finger-shaped pouch attached to the large intestine, located in the lower right side of the abdomen. Although the appendix does not have a major role in digestion, inflammation of this organ can become a serious condition if it is not treated on time.
Appendicitis usually occurs when the appendix becomes blocked, causing bacteria to multiply inside it. This leads to swelling, infection, and increasing pressure within the appendix. If untreated, the appendix may burst (rupture), allowing infection to spread into the abdominal cavity, which can cause a serious condition called peritonitis.
Appendicitis can occur at any age but is most common in people between 10 and 30 years old. The condition often develops suddenly, with symptoms becoming worse over several hours. The most common symptom is abdominal pain, which often begins around the belly button and later moves to the lower right side of the abdomen.
Doctors diagnose appendicitis through physical examination, medical history, and tests such as blood tests, urine tests, ultrasound, or CT scans. Early diagnosis is important because delayed treatment increases the risk of complications.
The main treatment for appendicitis is usually surgical removal of the appendix (appendectomy). In some cases, antibiotics may be used, especially when surgery is delayed or when treating certain uncomplicated cases under medical supervision.
Appendicitis usually occurs due to blockage and infection inside the appendix.
Possible causes include:
Hardened stool blocking the appendix opening
Swollen lymph tissue after infections
Bacterial growth inside the appendix
Inflammatory bowel conditions
Rare tumors of the appendix
Risk factors may include:
Age between 10–30 years
Family history of appendicitis
Certain intestinal infections
Low-fiber diet (possible association)
There is no guaranteed way to prevent appendicitis, but some healthy habits may help reduce digestive problems:
Eating a high-fiber diet with fruits, vegetables, and whole grains
Drinking enough water
Maintaining healthy bowel habits
Treating intestinal infections promptly
Following a balanced and healthy lifestyle
Early recognition of symptoms and immediate medical attention are important because untreated appendicitis can become life-threatening.
