The stomach varies depending on body type, position, and filling, with most of the stomach being located on the left side of the body. Medically, the human abdomen is artificially divided into 9 zones. To the lower edge of the ribs, the anterior superior iliac spine, the vertical line of the two nipples, the human body is divided into 9 zones (the patient can be imagined as a nine lattice hot pot), most of the stomach is the left upper side and the upper part of the middle lattice, medically referred to as the left quarter of the rib area and the supra-abdominal area. So under normal circumstances most of the stomach is located on the left side, a small portion is located on the right side. 1. Degree of filling: If the stomach is highly filled, it can reach the navel. In patients with gastroptosis, it can even reach the lower abdomen. 2. Body shape of the stomach: Different people have different stomachs, which are medically categorized into hook-shaped stomach, angular stomach and long stomach. Hook-shaped stomach is common in medium-sized people, and most of the stomach body is located on the left side; angular stomach is mostly located in the upper abdomen, compared with the other two types on the right side of the stomach body is more; straight stomach is almost all located on the left side. Regardless of the type of stomach, as long as it is within the normal range it is normal, and if symptoms of gastroptosis occur, patients are advised to visit a gastroenterologist promptly.
