What condition may cause left lower quadrant (LLQ) pain?

Left lower quadrant (LLQ) pain is most commonly associated with diverticulitis. This condition arises when diverticula, which are small pouches that can form in the walls of the colon, become inflamed or infected. The pain typically occurs in the LLQ because the sigmoid colon, where diverticula are often located, is situated in that region.

Patients with diverticulitis may also experience additional symptoms such as changes in bowel habits, fever, and abdominal tenderness. The inflammatory process can lead to complications such as abscess formation or perforation, which can further exacerbate symptoms and necessitate urgent medical treatment.

In contrast, appendicitis generally causes right lower quadrant pain since the appendix is located on the right side of the abdomen. Cholecystitis typically presents with pain in the right upper quadrant due to inflammation of the gallbladder. Pancreatitis generally causes pain in the upper abdomen and may radiate to the back, rather than specifically focusing on the LLQ. Therefore, diverticulitis is the appropriate condition associated with left lower quadrant pain.
