Coughing and Voice Loss (Dysphonia): Causes and Recovery

Excessive coughing can cause dysphonia (voice loss) by straining and inflaming the vocal cords. Mechanisms include:

1. Vocal cord strain: Prolonged forceful coughing tires and swells cords.
2. Inflammation: Swelling disrupts normal vibration, causing hoarseness.
3. Excess mucus: Coats cords, impairing vibration.
4. Muscle spasms: Surrounding muscles spasm, further impairing function.

Usually temporary, resolving with rest and treating the underlying cause. If hoarseness persists >2 weeks, see a doctor to rule out other conditions.
