However, it is considered an autoimmune condition where our immune system accidentally attacks healthy muscles. Myositis can be related to certain illnesses or viruses and drugs. Furthermore, people with particular genetic traits might be more prone to contracting the disease.


Symptoms of Myositis


Myositis is an uncommon autoimmune disorder that causes inflammation and weakening of muscles. Patients suffering from myositis experience different symptoms, including weakness of the muscles, particularly in the more proximal (closer to the centre of the human muscle) muscles, like the shoulders, hips, neck, and legs.

  • Dermatomyositis
  • Myositis in the body of the inclusion
  • Myopathy that is autoimmune and necrotizing
  • Juvenile myositis

  • Physical Examination

The doctor will examine the body to look for the presence of muscle weakness or wasting, in addition to any other physical indications of myositis.

  • Blood Tests

The results of blood tests can help detect inflammation and identify specific antibodies commonly found in patients with myositis.

  • Electromyography (EMG)

The test is designed to measure electrical muscle activity. It is a good way to establish if the weakness of muscles could be due to myositis or other conditions.

  • Magnetic Resonance Imaging (MRI)

An MRI can aid in visualizing the muscles and identifying any indications of inflammation.

  • Muscle Biopsy

A muscle biopsy removes a small amount of muscle tissue to be used in lab tests. It can aid in confirming the diagnosis of myositis as well as determine the exact kind of myositis that is present.

Plasma Exchange

This involves removing the plasma from the patient (the liquid component of the blood) and replacing it with fresh plasma or a specific solution. It may help in removing harmful substances from blood and lessen inflammation.

Physical Therapy

Increased Risk of Cancer

People who suffer from myositis are at an increased chance of developing cancer, especially lung cancer.

Risk Factors
