The location of the two threats is mainly below the axilla and above the 1-2 ribs, located on both sides of the chest, is a collective term. From the Chinese medicine point of view, since the veins of the liver meridian travel in the two hypochondrium areas, the bile is attached to the liver, and the pulse of Shaoyang follows the two sides of the hypochondrium, when the human body has pain in the two hypochondrium areas, it is generally closely related to liver and biliary diseases. In Western medicine, there is a distinction between the left and right hypochondrium. The right hypochondrium has the liver and gallbladder, and when hepatitis, cholecystitis, or bile duct stones occur, the right hypochondrium pain will also occur. The left hypochondrium refers to the spleen and stomach, and when duodenal ulcer or spleen disease occurs, specific symptoms of the left hypochondrium will also appear, which is more helpful in the clinical diagnosis of the disease.
