What Causes Appendicitis?

Appendicitis is typically caused by the blockage of the appendix, a small organ located in the lower right side of the abdomen. The blockage can occur due to various reasons, including:

  1. Obstruction: The most common cause of appendicitis is when the opening of the appendix, known as the appendiceal lumen, becomes blocked. This blockage can occur due to the buildup of hardened stool, called fecalith, or by enlarged lymphoid tissue in the appendix.
  2. Infection: In some cases, appendicitis may develop as a result of an infection. Bacterial or viral infections can cause inflammation and swelling of the appendix, leading to appendicitis.
  3. Intestinal parasites: Certain intestinal parasites, such as pinworms or roundworms, can migrate to the appendix and cause inflammation, resulting in appendicitis.
  4. Trauma: In rare instances, a direct injury to the abdomen may cause appendicitis. Blunt trauma or an abdominal injury can lead to inflammation and blockage of the appendix.

It’s important to note that while blockage of the appendix is a common trigger for appendicitis, the exact cause of the blockage or infection may vary from person to person. If you experience symptoms such as abdominal pain, fever, nausea, and loss of appetite, it’s crucial to seek immediate medical attention as appendicitis can lead to serious complications if left untreated.
