How long does a sore throat last after a gastroscopy?

Gastroscopy refers to the examination of the stomach using an endoscope. Sore throat following a gastroscopy typically recovers within 1-3 days, although the exact time may vary. If discomfort persists, timely medical attention is recommended.

During the gastroscopy, the doctor will use a local anesthetic to reduce discomfort in the throat and esophagus. For most people, this discomfort naturally subsides within a few hours to one day. If only mild sore throat is experienced after the gastroscopy without other severe symptoms, no special treatment is usually necessary. Drinking more water, resting, and avoiding smoking and alcohol consumption should help alleviate the sore throat within one day.

If the gastroscopy takes longer, the irritation and trauma to the throat area may be relatively greater, thus prolonging the recovery time. Some individuals may have weaker mucosal healing abilities, resulting in a slower recovery speed, which may require 2-3 days for full recovery. It is recommended to drink plenty of warm water and consume bland, easily digestible foods, such as millet porridge and vegetable porridge, while avoiding spicy, greasy, cold, and other irritating foods.

After the gastroscopy, it is advisable to protect your voice, avoid excessive talking, and speak softly. Applying a warm towel as a compress on the throat area can help promote local blood circulation and speed up recovery.
