K29.9: Gastroduodenitis, unspecified
Your stomach and the first part of your small intestine are inflamed.
The stomach is located in the upper abdomen. The stomach has a curved shape, and is connected to the gullet (oesophagus) at its upper end and with the first part of the small intestine at its lower end. Between the stomach and the small intestine there is a circular sphincter, the pylorus. The inside of the stomach is lined with mucous membrane.
Your gastric mucous membrane is inflamed. There are various causes that can encourage inflammation of the gastric mucous membrane. They include alcohol, bacteria, specific drugs and stress. Due to the inflammation, the gastric mucous membrane may be damaged.
In your case, the first part of the small intestine has become inflamed.
With a stomach inflammation, you may have nausea or pain. You may also have to vomit. It is also common to have no symptoms at all.
