My voice is gone, is this a part of bronchitis?

Yes: It can be. When you cough, you put high velocity small particles past the vocal folds, as well as strain the larynx to produce the cough. This can irritate and inflame the vocal folds, causing you to lose your voice.

Yes: It can be, but if you have lost your voice, your vocal cords are inflamed, and the irritation may be coming from your sinuses, as post nasal drip. This can be a symptom of sinusitis also. Some doctors think most cases of acute bronchitis are really sinus infections.

No: Your voice is gone because of the impact of something upon the vocal cords, which reside in the upper airway. Bronchitis occurs in the lower airways, exclusive of the vocal cords.

Maybe...: Laryngitis can occur if you have been coughing a lot, like when you have acute bronchitis. You need to rest your voice to reduce the inflammation of your vocal cords which means no straining your voice until it recovers. For example, no raising your voice, no singing, etc. Drink plenty of fluids and rest and your voice should recover. If it doesn't recover in a few days, see your doctor.
