Becker myths and facts

Myth Fact
Becker is a mild form of muscular dystrophy. Many people living with Becker may not realize how the disease advances. It’s often thought of as a slow, unpredictable, or mild form of muscular dystrophy. But recent long-term research reveals that once people with Becker start to notice changes in what they can do, they often continue to lose physical abilities steadily, year after year—which can have a serious impact on the way they move through life.
If someone with Becker doesn’t notice symptoms, the disease isn’t progressing. The reality is, muscle and heart health can be affected below the surface, even before it starts having a noticeable impact on day-to-day life.
In Becker, muscle function isn’t impacted until later in life. Skeletal muscle function decline can occur at any age. As muscle damage accumulates, it can be more difficult to perform everyday activities like walking or climbing stairs. Also, muscle loss is irreversible, which is why proactive intervention is so important.
People with Becker should avoid physical activity. With appropriate guidance and thoughtful pacing, maintaining an active lifestyle can actually be very beneficial for individuals living with Becker. Remaining active can minimize the potential of joint contractures, muscle fatigue, and optimize muscle functions critical to performing everyday activities. Your Care Team, including a physical therapist or occupational therapist, can help to develop an exercise program that best fits your needs and lifestyle.
Becker only impacts skeletal muscles. Becker can cause a variety of symptoms throughout the body, including weakening of the heart muscle, which can lead to heart rhythm disturbances and the heart not pumping blood as well as it should. Proactively working with a multidisciplinary Care Team may help people living with Becker stay ahead of potential complications.
People with Becker do not have a long life expectancy. The majority of individuals living with Becker live long, full lives. However, in some cases, people with Becker develop serious heart complications that can be life-threatening. Ongoing multidisciplinary care, including a cardiologist, is crucial.
There’s nothing that can be done to help manage Becker. It is possible to lead a fulfilling life with Becker muscular dystrophy. While there are currently no drug treatments specifically for Becker muscular dystrophy, there are plenty of resources and specialists who can help you manage your condition.

Connect with a knowledgeable healthcare provider to create a plan that helps support your muscle and heart health today. With the right attention, support, and understanding, you can take meaningful steps to stay engaged in the activities and moments that matter most to you.

What happens in Becker

A closer look at how Becker quietly affects muscle strength and heart health.

  • In people with Becker, a protein called dystrophin, which helps provide structural support for muscle fibers, doesn’t work correctly.
  • As a result, muscles are more susceptible to consistent wear and tear and ultimately lose the ability to repair themselves.
  • Because of this, activities like going up stairs, rising from a chair, catching yourself from a stumble, or walking downhill may be more difficult.
  • Over time, muscles are replaced with fat and scar tissue. This repetitive process is what causes muscle weakness and heart complications in Becker.

Physical activity is still appropriate for many people with Becker as long as it is thoughtful, paced, and guided with support from a multidisciplinary care team.

Getting a Becker diagnosis

Becker muscular dystrophy is a genetic disease that primarily affects boys and men.

Physical Examination

Becker muscular dystrophy diagnosis begins with a physical examination after initial symptoms appear.

#
#

Lab Tests

Elevated creatine kinase (CK) plasma level, which can be determined through a blood test that measures an enzyme released when muscles are damaged, guides toward a potential diagnosis of Becker muscular dystrophy. Individuals living with Becker muscular dystrophy may have up to 50 times the normal CK level.

#

Genetic Testing

Diagnosis is confirmed with genetic testing which identifies the underlying mutation.

If you know Becker runs in the family or suspect you or your loved one may be experiencing early symptoms of Becker, consider scheduling an appointment with your Primary Care Physician or a Neurologist to begin the diagnosis process.

Potential for confusion with other muscular dystrophies

Becker muscular dystrophy and Duchenne muscular dystrophy (DMD) are caused by a mutation on the dystrophin gene; both diseases may share symptoms and Becker may be initially diagnosed as Duchenne. Additionally, because Becker is a typically progressive disease affecting muscles, it may be confused with limb-girdle muscular dystrophy (LGMD). It is important to work with your Care Team to receive an accurate diagnosis and begin proactively managing your condition.

Understanding the symptoms of Becker

No matter where you are in your journey, it’s important to recognize the impact of Becker.

Many people don’t think I look like someone who would struggle with stairs, or who would need to take their time. But for me, it’s really important that I don’t frame my existence in terms of how other people would view me, but more so in terms of what I need.

Musculoskeletal Symptoms

Musculoskeletal Symptoms

Muscle weakness is a key symptom of Becker muscular dystrophy. Muscles in your body support functions critical to independent living, such as walking, getting dressed, and going to the bathroom.

Quick Facts:

When symptoms of Becker start, individuals living with Becker complain of muscle cramps and pain with strenuous physical activity.

Muscle weakness is usually noticed by age 15 and typically begins in the legs and pelvis area, potentially leading to walking problems. Over time, it may also impact the shoulders, neck, and arms. Muscle function loss is irreversible.

Cardiac Symptoms

Cardiac Symptoms

Since the heart is made of muscle, Becker muscular dystrophy can cause weakening of the heart. This may lead to heartbeat irregularities and the heart not pumping blood as well as it should in a condition called dilated cardiomyopathy. Dilated cardiomyopathy is a serious heart condition requiring cardiologist care. In some cases, dilated cardiomyopathy may be the first sign of Becker muscular dystrophy.

Other Symptoms

Becker may lead to other symptoms throughout the body, including difficulty breathing, developmental and behavioral issues, hormonal imbalances, gastrointestinal problems, and decreased joint mobility and bone mass. The types of symptoms you or your loved one are experiencing can help determine the types of specialists who may need to be included on your Care Team.

Decline doesn’t happen all at once.

In the early stages of Becker, some people may not notice changes in their muscle and heart health, even when repeated and irreversible injury is happening below the surface.

Becker may look different for everyone, but the underlying process and disease course are the same.

Once muscle weakness begins, it continues steadily year after year and can ultimately lead to loss of balance and mobility, including:

  • Difficulty standing up from a chair or going up stairs
  • Needing walking aids
  • Completely losing the ability to walk
  • Falls, accidents, and other complications

That’s why understanding and staying engaged in regular, ongoing care matters. Because a fall, injury, heart issue, or progressive loss of strength can permanently change what you’re able to do—like how you care for your family, enjoy the activities you love, or move through daily life on your own.
