Outlook

The prognosis for a cough will vary depending on the underlying cause. After the cause has been addressed, most acute coughs will get better within 2-3 weeks. People who smoke during their cough can expect a longer period before they are completely better. People with chronic cough often have more varied results, and people with chronic lung disease often have periods of resolution in addition to periods of worsening of the cough. Again, smoking will make a chronic cough last longer and should be avoided.
