Myopathy is the medical term for muscle disease.
Polymyositis is one of a group of muscle diseases known as the inflammatory myopathies, which are characterized by chronic muscle inflammation accompanied by muscle weakness. Polymyositis is a rare muscle disease caused by inflammation of the skeletal muscles and the surrounding tissues, such as the blood vessels that supply the muscles.

Those who are affected by certain diseases can also experience muscle wasting. In this genetic disease, a group of muscle diseases cause the damage of muscle fiber. There are three major types: dermatomyositis, polymyositis and inclusion body myositis. Muscle wasting causes a significant decrease in muscle strength and the ability to move the muscle, according to MedlinePlus 1. Myositis is the name given to a group of rare diseases known as the inflammatory myopathies.

Polymyositis affects skeletal muscles (those involved with making movement) on both sides of the body. The most common symptom is muscle weakness, usually affecting those muscles that are closest to the trunk of the body (proximal).

It is part of a larger group of diseases called myositis. In the United States, idiopathic inflammatory myopathies affect about 1 out of every 100,000 people. In this rare group of muscle diseases, the cause of the muscle inflammation is unknown (idiopathic).
Polymyositis affects skeletal muscles (those involved with making movement) on both sides of the body.

A myopathy is a muscle disease, and inflammation is response to cell damage. Polymyositis is one of a group of muscle diseases known as the inflammatory myopathies, which are characterized by chronic muscle inflammation accompanied by muscle weakness.

Polymyositis is a type of muscle disease called an inflammatory myopathy. The disease has a gradual onset and generally begins in the second decade of life. Polymyositis is a rare inflammatory disease that leads to muscle weakness, swelling tenderness, and tissue damage.

Polymyositis is a inflammatory muscle disease that causes weakness of the skeletal muscles, which control movement. Polymyositis affects the skeletal muscles. The muscles affected by polymyositis are the skeletal muscles (those involved with making movements) on … It includes dermatomyositis, juvenile dermatomyositis, polymyositis and inclusion body myositis.. All types of myositis cause chronic inflammation of the muscles and connective tissues. PM has more inflammatory changes in the muscle tissue, while NM has more necrosis and degeneration of the muscle fibers. Polymyositis is caused by the body’s immune system attacking its own muscles and tissues instead of foreign invaders such as viruses and bacteria. It is classified as a chronic Idiopathic inflammatory myopathy. POLYMYOSITIS: An inflammatory muscle disease that causes varying degrees of decreased muscle power. Polymyositis is a rare inflammatory disease that leads to muscle weakness, swelling tenderness, and tissue damage. It is rarely seen in persons under age 18; most cases are in adults between the ages of 31 and 60. It inflames your muscles and their related tissues, like the blood vessels that supply them. In a healthy individual, muscle wasting can occur as result of the lack of physical exercise. Polymyositis (PM) and necrotizing myopathy (NM) are two types of inflammatory myopathy characterized by characteristic features on a muscle biopsy. Polymyositis is one of the inflammatory myopathies, a group of muscle diseases that involves inflammation of the muscles or associated tissues, such as the blood vessels that supply the muscles. One of only three … Some muscle diseases occur when the body's immune system attacks muscles. Both lead to symmetric weakness and some degree of muscle wasting (atrophy). What is myositis?

The result is misdirected inflammation, hence the name inflammatory myopathies. The common diseases under this category are Duchenne, Myotonia, Becker, Limb Girdle and Oculopharyngeal. This damages muscle tissue and makes muscles weak.

There is no specific cure for it and the symptoms include weakness, immobility and imbalance. It is rarely seen in persons under age 18; most cases are in adults between the ages of 31 and 60. Polymyositis is a type of inflammatory myopathy, which refers to a group of muscle diseases characterized by chronic muscle inflammation and weakness.
