View detailsBloating
Bloating refers to the accumulation of gas in the abdomen, which can be caused by gastrointestinal diseases, abdominal surgery, excessive intake of certain foods, or stress. It is often accompanied by belching, discomfort, and excessive flatulence. Bloating indicates slowed intestinal peristalsis, which affects the passage of gas, or is caused by swallowing too much air or consuming gas-producing foods.
View detailsHypergastrinemia
Gastrin is a hormone secreted by G cells in the gastrointestinal tract. G cells are mainly distributed in the gastric antrum, with some also found in the gastric fundus, duodenum, and jejunum. Any factor that can increase G cell numbers or promote gastrin secretion can lead to hypergastrinemia, primarily caused by gastrinoma. Because gastrin causes excessive gastric acid, it can lead to symptoms such as refractory peptic ulcers, ulcer bleeding, gastrointestinal perforation, gastrointestinal stricture, and diarrhea.
View detailsDuodenitis
The duodenum is located between the stomach and the jejunum, and is named for its length, which is equivalent to the width of twelve fingers. Duodenitis refers to acute or chronic inflammation of the duodenum caused by various etiologies, primarily manifesting as upper abdominal pain, nausea, vomiting, hematemesis, and melena. It is more common in young and middle-aged adults, with a significantly higher incidence in males than females.
