An occasional hoarse voice is normal: You\u2019ve strained your voice shouting to be heard over loud music or while cheering on your favorite sports team, for example. But a chronic hoarse voice can have many different causes, from benign to serious. When you understand what\u2019s at the root of hoarseness, you can take steps to treat it and prevent it in the future.\nCommon Causes of a Hoarse Voice\nNormally, your vocal cords stay apart while you breathe and come together when you speak. As you exhale, this causes a vibration that results in sound. But if you develop swelling, growths, or other damage to your vocal cords, your voice can be affected.\nIn general, a hoarse voice has the following characteristics:\n\nRaspy\nStrained\nBreathy\nChanges in pitch or volume\n\nWhile some causes of hoarseness are temporary, others may require a visit with your physician. Typical culprits include:\n\nLaryngitis. Acute laryngitis is the most common reason for hoarseness. It occurs when your vocal cords swell, usually due a cold, upper respiratory infection, or straining your voice. It\u2019s important to rest your voice when you have acute laryngitis, because trying to speak loudly could damage your vocal cords.\nImproper voice use. Shouting isn\u2019t the only act that can make your voice hoarse. Excess talking, speaking at an abnormally high or low pitch, and even cradling a telephone between your ear and shoulder can contribute to this problem.\nVocal cord lesions. People who use their voice frequently (such as singers) can develop benign nodules, polyps, and cysts on the vocal cords that can lead to hoarseness.\nReflux. Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux disease (LPRD) can trigger hoarseness. In these conditions, stomach acid can rise through the esophagus and throat, irritating the vocal cords.\nSmoking. As you might imagine, smoking can make your voice hoarse. It can also increase your risk of throat cancer, another cause of hoarseness.\nOther\u00a0disorders. Neurological conditions such as Parkinson\u2019s disease, spasmodic dystonia, and stroke can affect the voice, as can thyroid disease, allergies, and laryngeal cancer.\n\nWhen to Call Your Doctor for Hoarseness\nTemporary hoarseness can be normal, especially if you have a cold, allergies, or recently strained your voice. Everyone is different, but you should contact your physician if your voice is still hoarse after three weeks, you have difficulty swallowing, feel like you have a lump in your throat, experience throat pain, or are coughing up blood. Also seek medical attention if you suddenly and completely lose your voice after shouting or straining: This could be a sign of a vocal cord hemorrhage, which is considered an emergency.\nFor more information on hoarseness or to schedule an appointment with one of our ENT doctors, please visit the UPMC Voice Center website.
