Will there be sore throat after gastroscopy examination?

After gastroscopy, there may be a sore throat, which is generally mild and short-lived. Gastroscopy requires inserting an endoscope through the throat, which may cause discomfort due to instrument friction or local irritation. Most cases can resolve on their own within 1-2 days. During gastroscopy, the endoscope may cause slight abrasions to the mucosa when passing through the throat, especially if the subject has swallowing reflexes caused by tension or prolonged operation time. After examination, some people may feel dry throat, foreign body sensation or dull pain, usually related to brief mucosal congestion. Drinking warm water and avoiding spicy food can alleviate symptoms. In rare cases, if biopsy is required during the examination or there are repeated intubation procedures, it may cause significant pain or swelling, but usually does not exceed 3 days. In rare cases, sore throat may be caused by allergies to anesthetic drugs or severe mucosal damage. If the pain persists for more than 3 days, accompanied by fever or difficulty swallowing, one should be alert to infection or deep tissue damage and promptly return to the hospital for examination. Patients with previous pharyngitis and reflux esophagitis may have more obvious symptoms after examination, but most of them are still within a controllable range.

Within 2 hours after the examination, avoid eating and drinking water to reduce the risk of coughing. Within 24 hours, choose a warm and cool liquid diet such as rice soup and lotus root powder to avoid stimulating the throat with hard or overheated food. If the pain is obvious, you can take throat lozenges such as Xidi iodine lozenges, but you need to rule out a history of allergies. Maintaining oral hygiene on a daily basis, rinsing with diluted salt water can help alleviate discomfort and avoid forceful coughing or throat clearing movements. If the symptoms do not improve or worsen, it is recommended to contact the endoscopy center for a follow-up examination.
