Which condition is associated with lower left quadrant pain?

Lower left quadrant pain is most commonly associated with diverticulitis, which occurs when diverticula—small, bulging pouches that can form in the lining of the digestive system—become inflamed or infected. The location of the pain is particularly relevant, as diverticulitis typically affects the descending colon, which resides in the left lower quadrant of the abdomen.

Patients with diverticulitis may also present with symptoms such as fever, nausea, and changes in bowel habits, which can help differentiate it from other abdominal conditions.

In contrast, conditions like appendicitis usually present with pain in the right lower quadrant. Pancreatitis typically causes pain in the upper abdominal regions that can radiate to the back, and ectopic pregnancy usually presents with pain in the lower abdomen or pelvis that may be lateralized; however, it is generally more associated with the right or left side depending on the location of the ectopic tissue. Therefore, the localization of pain is a key factor in identifying diverticulitis as the correct condition associated with lower left quadrant pain.
