Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis. Muscular dystrophy refers a group of disorders that involve a progressive loss of muscle mass and consequent loss of strength.
Muscular dystrophy is caused by genetic mutations that interfere with the production of muscle proteins that are needed to build and maintain healthy muscles. The causes are genetic. A family history of muscular dystrophy will increase the chance of it affecting an individual.
