Fibromyalgia and muscular dystrophy are two muscular system diseases that can affect teens.
Muscular dystrophy (or MD) is a "genetic disorder that weakens the muscles that help the body move." People who have MD are missing genes that code for the correct proteins needed for the production of healthy muscles. MD weakens the muscles over time until its victims cannot perform daily functions. As a genetic disorder, most people are born with MD. However, the onset of symptoms can as occur from infancy to adulthood.
Firbromyalgia is a long-term condition that causes pain in a person's joints, muscles, and soft tissues. Fibromyalgia also causes extreme fatigue. Its symptoms are most common in females between the ages of 20 to 50 years. However, firbomualgia's symptoms can arise in teenagers or even younger children.
