Left-sided abdominal pain is primarily attributable to disorders of pelvic visceral organs and is typically associated with either organic or functional diseases. Ulcerative colitis commonly affects the left colon or rectum, thus frequently manifesting as left-sided abdominal pain. Sigmoid volvulus—located in the left lower abdomen—can also cause left-sided abdominal pain. In irritable bowel syndrome (IBS), abdominal pain may occur anywhere in the abdomen, including the left side.

Additionally, acute pancreatitis is relatively common among male patients; when the pain localizes to the left upper quadrant, it may indicate this condition. Acute pancreatitis can cause severe left upper abdominal pain. Left ureteral or renal calculi may produce pain in the left flank or lower abdomen, often presenting as intense colicky pain. Beyond evaluating the patient’s specific symptoms, clinicians must also assess vital signs—including body temperature, pulse rate, respiratory rate, and blood pressure—when left-sided abdominal pain occurs. If the pain is severe, appropriate diagnostic tests should be performed promptly to establish a definitive diagnosis, followed by targeted treatment addressing the underlying cause.
