Most affected people respond well to treatment and regain muscle strength, although a certain degree of muscle weakness may persist in some cases. In most cases, polymyositis is not life-threatening, and many people recover partially or completely from the disease.
Is polymyositis serious?
If polymyositis is not treated, it can lead to severe complications. As the muscles become weaker, you may fall often and be limited in your daily activities. If the muscles in the digestive tract and chest wall are affected, you may have problems breathing (respiratory failure), malnutrition, and weight loss.
What is the mortality rate of polymyositis?
Five-year survival rates in polymyositis have been estimated at more than 80%. Mortality is most often related to associated malignancy or pulmonary complications; however, elderly patients with cardiac involvement or dysphagia also have a higher mortality rate.
Does polymyositis get worse over time?
The muscle weakness associated with polymyositis involves the muscles closest to the trunk, such as those in your hips, thighs, shoulders, upper arms and neck. The weakness affects both the left and right sides of your body, and tends to gradually worsen.
What triggers polymyositis?
What causes polymyositis? The cause of polymyositis is not known, but there are indications that heredity plays a role in the disease. Current research suggests that the condition may occur when immune system cells infiltrate and attack muscle tissue (an autoimmune process).
Does polymyositis run in families?
The disorder can run in families. There are four types of autoimmune myositis: Polymyositis.
Does polymyositis come go?

What is the life expectancy of someone with dermatomyositis?
Survival rates for PM were 87% (95% CI = 69 to 95) at 5 years and 69% (95% CI = 49 to 83) at 10 years, and for DM the rates were 70% (95% CI = 53 to 82) at 5 years and 57% (95% CI = 34 to 74) at 10 years (Figure 1). Kaplan-Meier estimates for survival in polymyositis (PM) and dermatomyositis (DM) patients.
How many people in the US have polymyositis?
What is polymyositis (PM)? Polymyositis is a rare disorder. In fact, it is believed that only about one in 5,000 people have polymyositis (or dermatomyositis) in the United States today.
