May be caused by a functional or organic lesion of the abdominal organs.
First of all, it is important to clarify whether the site of pain is the area where the stomach is located. According to the nine-point method, the location of the stomach in the abdomen is located in the upper abdomen, where organs such as the left lobe of the liver, the pyloric end of the stomach, the duodenum, the head and body of the pancreas, the transverse colon, the abdominal aorta, and other organs or tissues, the function of these structures or organic lesions such as inflammation or tumors may cause pain in the upper abdomen.
In addition the nature and characteristics of the pain are important in diagnosing the cause of abdominal pain.
Recurrent episodes of colic are most often seen in gastrointestinal spasm, which can be seen in diseases such as functional gastrointestinal disease and gastrointestinal infections.
Persistent epigastric pain can be seen in diseases such as gastrointestinal perforation, pancreatitis, and pancreatic cancer.
Burning and knife-like pain in the upper abdomen is most often seen in gastroduodenal ulcers, with typical symptoms of rhythmic epigastric pain that is associated with eating.
Lesions in other organs or systems of the body sometimes exhibit symptoms of epigastric pain, such as angina pectoris, lead poisoning, abdominal purpura, abdominal epilepsy, and other diseases that can also cause epigastric pain that can be easily misdiagnosed as a digestive disorder.
All in all, abdominal pain should be seen in the gastroenterology department of a regular hospital, where various factors should be analyzed and further tests should be performed to clarify the location and nature of the lesion and to develop an appropriate treatment plan.
