Living with Becker muscular dystrophy

A genetic condition, mostly in males, that slowly weakens heart and skeletal muscles.

Understanding Becker muscular dystrophy

Becker muscular dystrophy is a genetic condition that mainly affects males and slowly damages heart and skeletal muscles.

A lack of working dystrophin protein causes gradual damage and loss of muscle fibers. Symptoms can start anywhere from childhood to adulthood and slowly worsen. Sometimes heart muscle disease (cardiomyopathy) is the first sign. Severity varies a lot between people.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Muscle weakness
  • Trouble climbing stairs
  • Changes in the way a person walks
  • Falls
  • Tiring easily and trouble with exercise
  • Muscle aches or spasms

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, genetic specialists and heart and blood vessel specialists.

  3. Consider genetic testing

    Changes in DMD are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Hypertrophic Cardiomyopathy Association, Muscular Dystrophy Association and Children's Cardiomyopathy Foundation may keep lists of experts for this condition.
