What are the signs and symptoms of Becker muscular dystrophy?

The symptoms of Becker muscular dystrophy (BMD) may begin anywhere from childhood to a person's early 20s.[1][2] Muscle weakness often affects the legs and pelvis, and slowly gets worse.[1] Over time, affected people begin to have difficulty walking, frequent falls, difficulty with muscle skills (such as running, hopping, and jumping), and loss of muscle mass.[3] Eventually, affected people require a wheelchair.[2] The condition also affects the heart muscles, causing dilated cardiomyopathy. This form of heart disease enlarges and weakens the heart muscle, preventing it from pumping blood efficiently. Dilated cardiomyopathy progresses rapidly and is life-threatening in many cases.[1] Other symptoms of BMD may include cognitive problems, fatigue, loss of balance and coordination, problems breathing, and muscle weakness in the arms, neck and other areas.[3]
