How do people die from muscular dystrophy duchenne?

People with Duchenne muscular dystrophy (DMD) typically experience progressive muscle weakness and degeneration, which eventually affects vital muscles, including those responsible for breathing and heart function. As the disease advances, respiratory muscles weaken, leading to respiratory failure, and cardiac complications can arise due to heart muscle involvement. In many cases, individuals may succumb to complications related to these critical systems, often in their late teens to early adulthood. Supportive care and advancements in treatment can help manage symptoms and potentially extend life expectancy.
