When you can’t tell whether it’s stomach pain or gallbladder pain, you can make a diagnosis based on past medical history, symptomatic manifestations, or ultrasound, gastroscopy, and other tests to assist in the diagnosis. 1. Past medical history: If you have a past medical history of stomach pain or gallbladder pain, you can refer to the past medical history when you have pain again. However, the new pain may be different from the past medical history, and the diagnosis should be combined with the specific symptoms, imaging results and other comprehensive judgment. 2. Symptoms: Although stomach pain and gallbladder pain can be collectively referred to as abdominal pain, there are differences in their pain sites. Usually, the pain site of stomach pain is mainly located in the left side of the upper abdomen; the pain site of gallbladder is mainly concentrated in the right upper abdomen. Stomach pain is often manifested as persistent hidden pain, gallbladder pain is mostly manifested as paroxysmal colic. 3. Imaging examination: Through ultrasonography or gastroscopy, the imaging performance of the gallbladder or stomach can be clearly viewed. If the ultrasound examination finds that the gallbladder is enlarged and the wall of the gallbladder is thickened, the pain is usually considered to be caused by gallbladder disease; if the gastroscopy or ultrasound examination finds that the stomach wall is edematous, congested, and ulcerated, the pain is usually considered to be caused by gastric disease. If you can’t distinguish between stomach pain and gallbladder pain, you can make a judgment based on the pain manifestation, past medical history, etc. If necessary, you can go to the hospital for imaging examination to have a clearer understanding of the exact location and cause of the pain, so as to carry out targeted treatment as soon as possible.
