Which discomfort is commonly experienced after an EGD?

After an esophagogastroduodenoscopy (EGD), it is common for patients to experience a sore throat. This discomfort arises because the procedure involves the use of an endoscope, which is inserted through the mouth and can irritate the throat tissues. The scope may also cause temporary swelling or scratching, leading to a sensation of soreness or pain in the throat during the recovery period.

The other options, while they may occur in some cases, are not typical or expected post-procedural symptoms. For example, chest pain might raise concerns for potential complications but is not a common aftereffect of the procedure itself. Similarly, fever is not a typical direct outcome of an EGD; it could indicate an infection or other underlying issues if it occurs but is not associated with the procedure directly. Fatigue may occur in many patients post-procedurally but is more linked to the sedation used during the EGD rather than a specific discomfort from the procedure itself. Therefore, the most common and directly associated discomfort is indeed a sore throat.
