What happens to your larynx when you smoke?

Smoking can cause a range of changes and damage to the larynx, also known as the voice box, leading to various health problems. Here's what can happen to your larynx when you smoke:

1. Inflammation: Smoking irritates the delicate tissues of the larynx, leading to chronic inflammation. This inflammation can cause swelling and thickening of the vocal cords, resulting in hoarseness and a rough voice.

2. Polyps and Nodules: Prolonged irritation from smoking can cause the formation of polyps or nodules on the vocal cords. These growths can further interfere with the normal vibration of the vocal cords, resulting in voice changes and difficulty speaking.

3. Laryngeal Cancer: Smoking is a significant risk factor for developing laryngeal cancer, which starts in the cells of the larynx. Exposure to harmful chemicals in tobacco smoke damages the DNA of laryngeal cells, increasing the likelihood of cancerous transformations.

4. Vocal Cord Paralysis: Smoking can damage the nerves that control the movement of the vocal cords. This can lead to vocal cord paralysis, where one or both vocal cords become immobile. Vocal cord paralysis can cause significant voice problems, such as hoarseness, weak voice, and difficulty speaking.

5. Chronic Cough: Smoking can trigger a persistent cough, which further irritates the larynx and worsens vocal problems.

It's important to note that the effects of smoking on the larynx can vary from person to person, depending on factors such as the intensity and duration of smoking, individual susceptibility, and overall health. Quitting smoking is crucial for promoting laryngeal health and reducing the risk of associated voice disorders and cancers.
