The Left Upper Quadrant (LUQ) is a term used in anatomy to describe one of the four sections of the abdomen. It is located on the left side of the body, above the navel. This area contains important organs such as the stomach, spleen, and parts of the pancreas and kidneys. Medical professionals often assess the LUQ during physical examinations to identify potential health issues. Pain or discomfort in this region can indicate conditions related to the organs present, such as gastritis or splenic rupture. Understanding the LUQ is essential for accurate diagnosis and treatment.
