What is Muscular Dystrophy in Kids?
Muscular dystrophy (MD) is a group of inherited disorders in which the muscles that control movement (skeletal muscles) gradually weaken and waste away. In children, the most common form is Duchenne Muscular Dystrophy (DMD), usually seen in boys.
Root Cause
Genetic mutation: It happens because of changes in genes responsible for making proteins that keep muscles healthy.
In DMD, the dystrophin gene is affected → the body cannot produce enough dystrophin (a protein that strengthens and protects muscles).
Since it is inherited, it often runs in families, but sometimes mutations occur spontaneously without family history.
Symptoms in Kids
Symptoms usually start in early childhood (between 2–6 years):
Frequent falls, trouble getting up from sitting, lying position
Difficulty climbing stairs or running
Walking on toes or waddling gait
Enlarged calves (due to muscle tissue being replaced by fat)
Weakness in legs → later arms, neck, and trunk
Delayed motor milestones (walking, running, jumping)
Fatigue easily during play
In later stages: breathing or heart problems (as the disease progresses).
When to Consult a Doctor
See a doctor if your child shows:
Delay in walking compared to other kids
Frequent falls or trouble running, jumping
Noticeable muscle weakness (especially in legs)
Enlarged calf muscles
Struggles with everyday activities like climbing stairs or rising from the floor
