K31: Other diseases of stomach and duodenum
K31.2: Hourglass stricture and stenosis of stomach
The stomach is located in the upper abdomen. The stomach has a curved shape, creating a big curve and a small notch. The stomach is made up of different sections. Food reaches the entrance to the stomach through the gullet (oesophagus). The food is then transported into the body of the stomach. The fundus of the stomach is located at the top of the stomach. Air often collects there. There is a small extension further down in the stomach. This is the section in front of the end of the stomach or pyloric orifice. There is a sphincter muscle, the pylorus, at the end of the stomach. The pylorus transports the food in portions into the small intestine.
Your stomach is constricted in one place. If the stomach is too narrow in one place, food can then only make poor progress into the intestines. You may have to vomit as a result. It is also possible that you will have abdominal pain. You might lose weight.
