Gastroparesis needs to be determined by a combination of symptoms such as bloating, medical history such as diabetes, and blood biochemistry tests. The first step in determining gastroparesis is to identify the symptoms, such as abdominal pain, bloating, acidity, nausea, and loss of appetite, to determine whether there is a pathological manifestation. Secondly, in combination with the history of diabetes, depression, taking chemotherapy drugs, anesthesia and other medication history, gastrointestinal diseases, taking medication, surgery, etc., damage to the vagus nerve or smooth muscle, there may be gastroparesis, and need to look for and understand the possible causes. It is also important to combine endoscopy and ultrasound to rule out organic diseases such as gastric ulcer and gastritis. Barium X-ray of the upper gastrointestinal tract and gastric scintigraphy can be done to determine gastric emptying. Gastrogram can also be done to observe the slow wave activity if there is a delay in gastric emptying thus determining gastroparesis. In addition, patients with the above symptoms and history of discomfort cannot judge whether they have gastroparesis on their own, and patients with gastroparesis need to consult regular hospitals for diagnosis and treatment in a timely manner in order to avoid delaying their condition.
