How can one determine if they have appendicitis?

Generally, to determine whether one has appendicitis, the condition can be confirmed through characteristics of pain, physical examination, routine blood tests, ultrasound examinations, and potential inducing factors. If abnormalities are detected, timely medical consultation is recommended. Detailed analysis is as follows:

1. Observe the characteristics of pain: A classic symptom of appendicitis is shifting right lower quadrant abdominal pain, meaning the pain may initially appear in the upper abdomen or around the navel, and then migrate and localize to the right lower abdomen after several hours. If this pain pattern is observed, appendicitis should be highly suspected.

2. Perform a physical examination: The doctor will palpate the patient's abdomen to locate a fixed tender point in the right lower quadrant, known as McBurney's point tenderness. Some patients may also exhibit rebound tenderness, which is increased pain upon releasing pressure after pressing on the tender area. This is an important clinical sign of appendicitis.

3. Conduct a routine blood test: Patients with appendicitis typically show elevated white blood cell count and increased proportion of neutrophils, reflecting the body's inflammatory response. Routine blood testing helps doctors determine whether an infection exists and its severity.

4. Perform an ultrasound examination: Ultrasound can visualize the morphology, size, position of the appendix, and surrounding tissues. For patients suspected of having appendicitis, ultrasound helps confirm whether the appendix is swollen, thickened, or if there is abnormal fluid accumulation in the surrounding areas.

5. Consider inducing factors: Appendicitis can be triggered by certain factors, such as overeating, strenuous exercise, or a history of chronic appendicitis. Combining these factors with the patient's symptoms and physical signs can further improve the diagnostic accuracy for appendicitis.

If appendicitis is diagnosed, surgical removal of the appendix is generally required. Common surgical procedures include laparoscopic appendectomy and open appendectomy.
