A hoarse voice can be a symptom of acid reflux. As the stomach acid starts to seep into the esophagus, it starts to irritate the vocal cords and its associated nerve supply. Damage to any of these structures can lead to hoarseness of the voice.
Hoarseness usually develops due to damage on one side of the vocal cord or when a unilateral nerve is damaged. However, bilateral damage can result in complete malfunctioning of the vocal cords, and you may lose your voice permanently. Thus, pay close attention to the condition if your voice suddenly becomes huskier than usual. If it happens right after you take a meal, it can be an indication of reflux.
