The short explanation
A hoarse voice that lasts more than three weeks should be checked by a doctor, usually an ENT specialist. Common causes include overuse of the voice, acid reflux, smoking, infections, allergies, thyroid problems and harmless growths on the vocal cords such as nodules or polyps. Less commonly, a lasting hoarse voice can be a sign of cancer of the voice box, throat or, sometimes, the lung or thyroid pressing on a nerve. An ENT doctor can look at your vocal cords with a small camera, a quick test done in the clinic, to find the cause.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Smoking, tobacco chewing and heavy alcohol use raise the risk of throat and voice box cancer.
- Difficulty swallowing, a lump in the neck, coughing up blood, ear pain or weight loss make the check more urgent.
- Resting the voice and treating reflux may help, but a lasting change still needs examination.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what is causing your hoarse voice. An ENT examination is needed.
