Does stomach ache need to do gastroscopy

Stomach pain

is a common symptom and can be caused by a variety of causes, including peptic ulcer, gastritis, gastroesophageal reflux disease, cholecystitis, cholelithiasis, etc. If the cause is clear through medical examinations such as physical examination, blood test, CT examination, etc., an gastroscopy is not required. However, if the diagnosis cannot be confirmed by the above examinations, an gastroscopy is required for further diagnosis.

The examiner should keep an empty stomach for 6 to 8 hours before the gastroscopy. The main reason is to ensure that there is no food left in the stomach so that the doctor can clearly observe the gastric mucosa.
