Hello, Thankyou for the query at healthcare magic Hoarsness of voice can occur due to laryngitis as a result of bacterial /viral infection, allergies, vocal nodules, Gastro Esophageal reflux disease ( GERD), hypothyroidism,voice over use etc Since you have a history of GERD it is a likely possibility. Also thyroid level have to be checked to confirm that you are receiving adequate supplementation of thyroid hormone. However thorough ear,nose and throat examination is needed at this time to come to a definite diagnosis. I recommend that you consult an ENT specialist for further evaluation and management. Mean while give voice rest , warm saline water gargle and continue treatment of GERD Here are few tips to help control GERD -Avoid fatty,fried and spicy food -Do not go to bed immediately after eating. Give atleast two hours between dinner and bed time. -Avoid carbonated,caffeinated drinks -Limit alcohol consumption and avoid smoking -Raise the head end of bed using wood blocks under bed post. -Medications like pantoprazole Hope I was able to answer your question Please feel free to address any more concerns Regards, Dr.Lekshmi
