The stomach is in the left upper abdomen of the body, connected to the esophagus above and the duodenal bulb below, and its projection on the body surface is located three transverse fingers above the umbilicus below the xiphoid process, but the location of the stomach can change depending on body size, position, and the emptiness of the stomach. The stomach is located in the upper left part of the abdominal cavity, below the heart, mostly in the left quarter ribs and a small portion in the epigastrium. The stomach is connected upward to the lower esophagus through the cardia and downward to the duodenal bulb through the pylorus. Its body projection is located three transverse fingers above the umbilicus below the xiphoid process. Stomach disorders are often characterized by pain to the left of the epigastric region, but most patients present with subxiphoid pain or pain in an unknown location in the epigastric region. The position of the stomach also varies greatly depending on body type, body position, and the emptiness of the stomach. The position of the stomach is higher in short and fat people and lower in long and thin people. The lowest point of the greater curvature of the stomach is downward to the level of the iliac crest when the stomach wall muscle tone is low and standing after a full meal. The stomach is an intraperitoneal organ with the anterior and posterior walls covered by peritoneum. The anterior wall of the stomach is adjacent to the left hemi-liver on the right side and to the diaphragm on the right side, and its posterior wall separates the omental bursa from the pancreas, the left adrenal gland, the left kidney, the spleen, the transverse colon and its mesentery. If it is feeling pain or discomfort in the location of the stomach, it is recommended that the patient actively seek medical attention, do not self-diagnosis, so as not to delay the condition.
