Prognosis

What is the long-term outlook for people with polymyositis?

The long-term outlook (prognosis) for people with polymyositis varies. Most affected people respond well to treatment and regain muscle strength, although a certain degree of muscle weakness may persist in some cases.[1] If the treatment is not effective, people may develop significant disability.[2]

In rare cases, people with severe and progressive muscle weakness will develop respiratory failure or pneumonia. Difficulty swallowing may cause weight loss and malnutrition.[2]
