Right lower quadrant (RLQ) pain is most commonly associated with which condition?

Right lower quadrant (RLQ) pain is most commonly associated with appendicitis due to the anatomical location of the appendix. The appendix is situated in the RLQ of the abdomen, and when it becomes inflamed, it typically produces intense pain in this area. This pain often begins around the umbilical region and then localizes to the RLQ as the condition progresses.

In the case of appendicitis, other symptoms may include nausea, vomiting, fever, and changes in appetite, which can help differentiate it from other abdominal issues. The classic presentation of RLQ pain is a key diagnostic factor for physicians when considering appendicitis as a potential diagnosis in patients presenting with acute abdominal pain.

While the other conditions listed can also cause abdominal pain, their presentations are usually associated with different quadrants or specific symptoms that do not point directly to the RLQ as prominently as appendicitis does. For example, diverticulitis typically causes pain in the left lower quadrant, cholecystitis is often linked to the right upper quadrant, and pancreatitis usually presents with pain in the upper abdomen that can radiate to the back.
