The hypochondria are the parts of the abdomen on either side above the line level with the navel. The right upper hypochondrium is next to certain organs including the liver and gallbladder. Pain in this part of the abdomen is often associated with disorders affecting these organs. The most common diseases involved in the onset of pain in the right upper hypochondrium are gallbladder stones responsible for biliary colic pain, hepatitis, or other, sometimes painful, liver diseases. Depending on the suspected cause, biological tests, such as an ultrasound or CT scan, may be performed.
