Typically, for patients who have had thyroid surgery, a gastroscopy can be done about a month after surgery. After having surgery on the thyroid area, the skin usually recovers gradually and returns to basically normal in about a month. And since gastroenteroscopy does not have a significant adverse effect on the esophagus and the gastrointestinal tract, it is possible to have a gastroenteroscopy at this time. Gastroenteroscopy can accurately observe the gastrointestinal tract and accurately grasp the condition of the gastrointestinal tract, which is conducive to the development of the next treatment plan. Patients who need to do gastroenteroscopy should pay attention before the examination, do not eat, do not drink water, so as to avoid the occurrence of aspiration and other adverse consequences during the examination. Post-thyroid surgery patients who need to undergo gastroenteroscopy should consult a doctor at a regular hospital before undergoing the examination.
