<ul>
<li>viral infection </li> <li>bacterial or fungal infection </li> <li>inflammation due to overuse of the vocal cords </li> <li>excessive coughing </li> <li>excessive alcohol consumption </li></ul><p> </p><h2><span class="mw-headline">Symptoms</span></h2><p>Symptoms of laryngitis vary, depending on the severity and also the cause. The most common, and obvious, symptom is impaired speech, ranging from a raspy hoarseness to the total loss of ability to speak, except at a whisper. Other symptoms can include:</p><ul> <li>Dry, sore throat </li> <li>Coughing, which can be a symptom of, or a factor in causing laryngitis; </li> <li>Difficulty swallowing; </li> <li>Sensation of swelling in the area of the larynx; </li> <li>Cold or flu-like symptoms (which, like a cough, may also be the causing factor for laryngitis;) </li> <li>Swollen lymph glands in the throat, chest, or face; </li> <li>Fever </li></ul><p>In most instances, the symptoms accompanying laryngitis are more directly linked to the causative factor, such as infection. In cases caused by overuse of the voice, symptoms other than vocal impairment may be absent.</p><p>If laryngitis is due to gastroesophageal reflux:</p><ul> <li>The patient may be instructed to take a nonprescription medication such as Zantac or Prilosec for a period of 4-6 weeks. </li></ul><p>If laryngitis is due to a bacterial or fungal infection:</p><ul> <li>The patient may be prescribed a course of antibiotics or anti-fungal medication. </li></ul><p>If persistent hoarseness or loss of voice (<em>sometimes called</em> "laryngitis") is a result of vocal cord nodules:</p><ul> <li>Physicians may recommend a course of treatment that may include a surgical procedure and/or speech therapy. </li> <li>Reduction of high-impact stress to the vocal cords caused by loud, frequent, and rapid speech is recommended. </li></ul><p> </p><h2><span class="mw-headline">References</span></h2><ol class="references"> <li id="cite_note-0"><strong>^</strong> University of Michigan Health System. 2005.
