Gastroesophageal Reflux Disease also known as “GERD” is a very common condition with millions of patients suffering in the US. Most patients have symptoms of heartburn and regurgitation of acid. Sometimes the acid comes up all the way into the throat area and causes symptoms such as sore throat, post nasal drainage, repeated throat clearing, hoarseness of voice, and sinus infections. At times such symptoms may be indistinguishable from allergy related symptoms. If the symptoms are due to allergy, they will respond to anti-allergy medications and nasal irrigation and washings by using products such as Sinus Rinse and Netipot. If such symptoms fail to respond to conventional anti-allergy measures, you should consider consultation with an ENT (Ear, Nose, and Throat) physician who can then evaluate you further. His/her examination may then indicate if your sinus symptoms are due to GERD. In such instances, treatment of GERD may improve your symptoms.
