Learn More About Myositis

One of the first steps after a myositis diagnosis is understanding the condition. Diplomat is here to help.

But remember: The information here — and on linked sites — is not meant to replace advice, care, or a diagnosis from your physician. If you have questions about your condition, please ask your provider.


Myositis, also known as myopathy, includes various chronic inflammatory disorders affecting muscle tissue, beginning with larger muscle groups. While the disorders differ in significant ways, each involves the slow progression of muscle weakness.

Physical exertion, including standing in place for an extended period, might leave patients fatigued. As myositis progresses, more muscles are affected. It’s possible for swallowing and breathing to become a challenge. Other potential side effects include muscle tenderness or a low level of constant muscle pain.

The most common types of myositis include, polymyositis, which often causes muscle and mobility loss; dermatomyositis, often accompanied by rashes; inclusion body myositis (IBM), which can lead to muscle weakness; and juvenile myositis, which can cause irreversible shortening of muscles around joints.

Although most adults will not experience a cure for myositis, many of its symptoms can be treated.
