Yes, it is possible to experience hoarseness after an upper endoscopy. This procedure involves inserting a flexible tube with a camera through the mouth and into the esophagus and stomach, which can sometimes irritate or impact the vocal cords. Additionally, if sedation was used during the procedure, the throat may be sore due to intubation or the presence of instruments.
If you experience persistent hoarseness, difficulty breathing, or other concerning symptoms after the procedure, it is advisable to contact your healthcare provider for further evaluation.
