My voice is very hoarse: what should I know?

Hoarseness can make your voice rough, breathy, weak, or lower than usual. A Common Cold may inflame the throat and voice box, while shouting, singing, frequent throat-clearing, smoke, or dry air can strain the vocal cords. Acid Reflux may irritate the voice box, sometimes with a sour taste or symptoms after lying down. Less common causes include an underactive thyroid or a problem affecting the throat, thyroid, or lungs. A hoarse voice is a common presentation of these conditions when they affect the relevant structures; it does not by itself identify the cause.

Rest your voice by speaking briefly and at a comfortable volume; avoid whispering, shouting, and singing. Drink fluids, avoid smoke and vaping, and use moist air if your room is dry. Do not repeatedly clear your throat. If reflux symptoms accompany the change, mention them to a clinician rather than starting long-term treatment on your own. Arrange a routine appointment if the hoarseness does not settle, keeps returning, or interferes with work or swallowing.

Seek urgent help for difficulty breathing, noisy breathing, inability to swallow saliva, rapidly increasing throat swelling, or a blue or grey colour around the lips. Get prompt medical advice for coughing blood, a neck lump, unexplained weight loss, persistent ear pain, or hoarseness that continues. These warning signs can occur with serious throat or chest conditions and should not be judged by the sound of the voice alone.

When did the voice change begin, and could infection, voice strain, reflux, medicines, or smoking be contributing? Do I need an examination of my throat or vocal cords? What symptoms should make me return sooner?
