What does pain in the upper midabdominal area refer to in medical terminology?

Pain in the upper midabdominal area is referred to as the epigastrium in medical terminology. This term specifically designates the region located just below the ribcage and between the two hypochondriac regions of the abdomen. The epigastric area is significant in clinical practice, as pain here can be associated with various gastrointestinal disorders, including conditions affecting the stomach, pancreas, or even referred pain from cardiac issues.

The other areas mentioned, such as the peritoneum, mediastinum, and retroperitoneum, refer to structures or spaces within the body that are not specifically related to the upper midabdominal region. The peritoneum is the serous membrane lining the abdominal cavity and covering the abdominal organs, while the mediastinum is the central compartment of the thoracic cavity. The retroperitoneum refers to the space behind the peritoneum, which contains the kidneys and other structures, and is also not specific to upper midabdominal pain.
