Overview and Definition
Appendicitis is a medical emergency characterized by the rapid inflammation of the appendix. The appendix is a small, finger-shaped tube or pouch attached to the cecum, which is the beginning of the large intestine. It is located in the lower right quadrant of your abdomen. While the exact function of the appendix in adults is still debated by researchers (some believe it acts as a storehouse for good bacteria), it is clear that you can live a normal, healthy life without it. When the appendix becomes inflamed, it swells and fills with pus, creating a dangerous situation that requires immediate medical attention.
If left untreated, an inflamed appendix can eventually burst or rupture. A rupture spills infectious materials and bacteria into the abdominal cavity, leading to peritonitis—a severe and potentially life-threatening inflammation of the abdominal lining. Because of this risk, appendicitis is universally treated as an acute surgical emergency.
Symptoms and Risk Factors
Patients frequently ask what does appendicitis feel like? Typically, the pain begins as a sudden, dull ache around the belly button (navel). Over the course of a few hours, this pain migrates down to the lower right side of the abdomen, where it becomes much sharper, constant, and severe. The pain often worsens if you cough, walk, or make jarring movements.
Beyond the localized pain, common appendicitis symptoms include a sudden loss of appetite, nausea, and vomiting that start shortly after the abdominal pain begins. Other classic signs of appendicitis include a low-grade fever that may worsen as the illness progresses, abdominal bloating, and either constipation or diarrhea. It is important to note that the symptoms of appendicitis can present differently in young children and pregnant women, where the pain might seem to originate in a different area due to the shifting of internal organs.
When determining what causes appendicitis, the primary culprit is almost always a blockage in the lining of the appendix that leads to an infection. This obstruction is most commonly caused by a buildup of hardened stool (a fecalith).
It can also be caused by enlarged lymphoid follicles resulting from a viral or bacterial infection elsewhere in the body, or, less commonly, by a foreign body, trauma, or tumors. Once blocked, the bacteria naturally present inside the appendix multiply rapidly, causing the organ to become inflamed, swollen, and filled with pus.
Diagnosis and Evaluation
Diagnosing this condition quickly is vital. A doctor will begin with a physical exam to assess your pain, looking for “rebound tenderness”—pain that worsens when pressure applied to the lower right abdomen is suddenly released. Blood tests are ordered to check for a high white blood cell count, indicating an infection. To confirm the diagnosis and rule out other causes of abdominal pain (like kidney stones or ectopic pregnancies), doctors rely heavily on imaging tests, such as an abdominal ultrasound or a CT scan.
During evaluation, imaging helps doctors determine the severity of the inflammation, which is generally categorized into the 4 stages of appendicitis:
Treatment and Management
The standard and most definitive treatment for appendicitis is the surgical removal of the inflamed organ, a procedure known as an appendectomy.
In some specific, uncomplicated cases of early appendicitis, doctors may initially treat the condition with a course of strong intravenous antibiotics rather than immediate surgery. However, surgery remains the gold standard, as treating with antibiotics alone carries a significant risk of the appendicitis recurring later.
Recovery and Prevention
Recovery from an appendectomy depends largely on whether the appendix ruptured and the type of surgery performed. After a laparoscopic appendectomy, patients often go home the same day or the next day, and can usually return to normal, non-strenuous activities within one to three weeks. If an open surgery was required due to a rupture, the hospital stay will be longer (often several days) to administer IV antibiotics, and full recovery can take up to six weeks. Patients are advised to avoid heavy lifting and strenuous exercise during the healing process.
Currently, there is no proven way to prevent appendicitis. However, the condition appears to be less common in people who eat diets high in fiber, such as fresh fruits, vegetables, and whole grains. A high-fiber diet helps keep stool soft and moving through the digestive tract, which theoretically reduces the risk of a fecal blockage forming in the appendix.

Appendicitis is the sudden swelling of the appendix, a small pouch attached to the large intestine. A general surgeon performs an appendectomy, which is the surgical removal of the inflamed appendix, usually through a minimally invasive (laparoscopic) procedure.
Appendicitis itself is the condition. Treatment focuses on resolving the severe inflammation and infection caused by a blockage in the appendix and preventing it from rupturing.
The main types are Acute Appendicitis (sudden inflammation) and Perforated Appendicitis (where the appendix has ruptured, which is a medical emergency).
You should see a doctor immediately, usually by going to the emergency room, if you have severe abdominal pain that starts near the belly button and moves to the lower right abdomen, especially if it is accompanied by fever or vomiting.
