Muscular dystrophy is a group of genetic disorders that cause progressive weakness and loss of muscle mass. It occurs when the body cannot produce certain proteins needed for healthy muscle development. The severity and symptoms can vary widely among different types of muscular dystrophy, affecting mobility and overall physical function. There are several types of muscular dystrophy, including Duchenne muscular dystrophy and Becker muscular dystrophy. These conditions primarily affect boys, but some forms can also affect girls. While there is currently no cure, treatments such as physical therapy and medications can help manage symptoms and improve quality of life.
