What causes swelling under right rib cage?

Swelling under the right rib cage can occur for multiple reasons and may be accompanied by other symptoms that help identify the underlying cause. Bloating is a condition where excess gas or fluid accumulates in the stomach or intestines, causing the abdomen to feel full and distended. This can result in noticeable swelling in any part of the abdominal area. Swelling could also be related to various organs located in this area, including the liver, gallbladder, and part of the large intestine. These organs can experience inflammation or other issues that lead to noticeable swelling in the right upper quadrant of the abdomen. Common conditions affecting these organs include hepatomegaly (enlarged liver), cholecystitis (gallbladder inflammation), or colitis (intestinal inflammation). Understanding which organ is affected helps determine the appropriate treatment approach.
