Physical examination of the abdomen is mainly to check whether there is a problem with the abdominal organs, which is checked by palpation, pressing the abdomen to see whether the patient has pain, whether there is muscle tension and peritoneal irritation, etc. It can also check whether there is a mass in the abdomen, which can determine the size of the mass and how active it is, and make a preliminary diagnosis of the disease, which is also checked by instruments. The main organs of the human body are located in the abdomen, and if abnormalities occur in the abdominal organs, they can be initially determined by pressure, which can be manifested as pain and the presence of masses. Pain in the upper abdomen is common in diseases such as cholecystitis, acute gastritis, pancreatitis, and in serious cases, gastrointestinal perforation and gallbladder perforation. If there is pain in the lower and middle part of the abdomen, it is usually acute enteritis and intestinal obstruction, and it is also common in gynecological diseases, such as lesions in the uterine adnexa and ovarian cysts, and chest diseases, which can also be examined by palpation, such as acute myocardial infarction, pericarditis and pneumonia, can also be examined by pressing on the abdomen.
