Polymyositis is a rare autoimmune disease that affects the muscles in the body, causing inflammation and muscle weakness. It is a chronic condition that can be difficult to diagnose and manage. In this article, we will discuss what polymyositis is, how it is an autoimmune disease, common tests and treatment options, as well as potential medications, natural remedies, and suitable diets for those who have polymyositis.
What is Polymyositis?
Polymyositis is a type of inflammatory myopathy, which means it is a condition that affects the muscles and causes inflammation. Specifically, polymyositis affects the skeletal muscles, which are the muscles that control movement in the body. This condition is considered to be rare, with an estimated prevalence of 10 cases per million people.
The exact cause of polymyositis is unknown, but it is thought to be an autoimmune disease. This means that the body’s immune system mistakenly attacks its own healthy cells and tissues, in this case, the muscles. The immune system produces antibodies that attack the muscle fibers, causing inflammation and muscle weakness.
Polymyositis can affect people of any age, but it is most commonly diagnosed in people between the ages of 30 and 60. It affects both men and women equally. The symptoms of polymyositis can vary from person to person and may develop slowly over time.
Symptoms of Polymyositis
The symptoms of polymyositis are primarily related to muscle weakness, particularly in the muscles that are closest to the trunk of the body, such as the hips, thighs, shoulders, and neck. The following are some common symptoms of polymyositis:
- Muscle weakness, particularly in the hips, thighs, shoulders, and neck
- Difficulty swallowing or breathing
- Fatigue
- Joint pain and stiffness
- Weight loss
- Muscle pain
- Raynaud’s phenomenon, which is a condition where the fingers and toes turn white or blue in response to cold temperatures or stress
- Skin rash, particularly on the eyelids, knuckles, and knees
Diagnosing Polymyositis
Diagnosing polymyositis can be challenging, as the symptoms can be similar to those of other conditions. However, there are several tests that can help to diagnose the condition and rule out other possible causes of muscle weakness.
The first step in diagnosing polymyositis is to perform a physical exam and take a detailed medical history. The doctor may ask about the patient’s symptoms, any family history of autoimmune disease, and any medications or supplements the patient is taking.
Blood tests can also be helpful in diagnosing polymyositis. Elevated levels of certain enzymes, such as creatine kinase (CK) and aldolase, can indicate muscle damage. Blood tests can also detect antibodies that are associated with autoimmune diseases, such as antinuclear antibodies (ANA) and anti-Jo-1 antibodies.
An electromyogram (EMG) is another test that can help to diagnose polymyositis. This test measures the electrical activity of the muscles and can detect abnormalities in the muscles that are consistent with polymyositis.
A muscle biopsy may also be performed to confirm the diagnosis of polymyositis. During a muscle biopsy, a small piece of muscle tissue is removed and examined under a microscope to look for signs of inflammation and muscle damage.
Treating Polymyositis
The treatment for polymyositis typically involves a combination of medication, physical therapy, and lifestyle changes. The goal of treatment is to reduce inflammation, relieve symptoms, and prevent muscle damage.
Medications
Corticosteroids, such as prednisone, are often the first line of treatment for polymyositis. These

The treatment for polymyositis typically involves a combination of medication, physical therapy, and lifestyle changes. The goal of treatment is to reduce inflammation, relieve symptoms, and prevent muscle damage.
Corticosteroids, such as prednisone, are often the first line of treatment for polymyositis. These medications are powerful anti-inflammatory drugs that can reduce inflammation in the muscles and improve muscle strength. However, corticosteroids can have significant side effects, such as weight gain, high blood pressure, and increased risk of infection.
Medications
Immunosuppressant medications may also be prescribed to help control the immune system and reduce inflammation. These medications, such as methotrexate, azathioprine, and mycophenolate mofetil, work by suppressing the activity of the immune system, but they can also increase the risk of infection and other side effects.
Intravenous immunoglobulin (IVIG) therapy may also be used to treat polymyositis. IVIG is a medication that contains antibodies from healthy donors, which can help to control the immune system and reduce inflammation.
Physical Therapy
Physical therapy can help to improve muscle strength and function in people with polymyositis. A physical therapist can design an exercise program that is tailored to the individual’s specific needs and abilities.
Lifestyle Changes
People with polymyositis may need to make lifestyle changes to manage their condition effectively. This may include getting enough rest, eating a healthy diet, and avoiding triggers that can exacerbate symptoms, such as stress and cold temperatures.
Natural Remedies
While there is no cure for polymyositis, some natural remedies may help to alleviate symptoms and improve quality of life. These remedies may include:
- Acupuncture: Acupuncture is a form of traditional Chinese medicine that involves inserting fine needles into specific points on the body. It may help to reduce inflammation and relieve pain.
- Massage therapy: Massage therapy can help to reduce muscle tension and improve circulation, which may help to alleviate symptoms of polymyositis.
- Yoga: Yoga can help to improve flexibility and reduce stress, which may help to improve muscle function in people with polymyositis.
Dietary Recommendations
There is no specific diet that is recommended for people with polymyositis, but it is important to maintain a healthy and balanced diet. This may include:
- Eating a variety of fruits and vegetables, whole grains, and lean proteins
- Limiting processed foods, sugar, and saturated fats
- Drinking plenty of water to stay hydrated
- Avoiding alcohol, which can interact with some medications used to treat polymyositis
