Muscular Dystrophy
Informed by recognized medical guidance
Overview
Muscular dystrophy is a group of inherited conditions that cause muscles to become progressively weaker and lose tissue over time. It is not one single disease, but many different types that vary in when they start, which muscles they affect, and how fast they get worse.
Key facts
- Muscular dystrophy is caused by changes in genes that are important for muscle health.
- There are many different types, and symptoms can range from mild to severe.
- There is currently no cure, but treatments can help manage symptoms, improve quality of life, and support independence.
- Most types of muscular dystrophy affect boys more often than girls, especially the most common type.
Muscular dystrophy is rare. The most common type in children, Duchenne muscular dystrophy, affects about 1 in every 3,500 to 5,000 boys. Other types are much less common.
Muscular dystrophy can affect people of all ages and backgrounds. Some types are diagnosed in early childhood, while others only cause symptoms in adulthood. Because most types are inherited, it often runs in families, but it can also happen in people with no family history.
Symptoms
- Sudden difficulty breathing or feeling like you cannot get enough air
- Chest pain or pressure
- Choking or being unable to swallow at all
- Fainting or passing out
- Sudden loss of the ability to move a limb
- ⚠New or worsening trouble breathing
- ⚠Difficulty swallowing that makes it hard to drink or take food
- ⚠A fall with a painful injury or a head injury
- ⚠Signs of a chest infection, such as a high fever, cough with phlegm, or fast breathing
- ⚠Sudden increase in muscle weakness over a few days
Common symptoms
- Progressive muscle weakness, often starting in the hips, thighs, or shoulders
- Difficulty walking, running, climbing stairs, or getting up from the floor
- Frequent falls or problems with balance
- Muscle pain, stiffness, or cramps
- Enlarged calf muscles (in some types, the muscles look bigger but are weak)
- Fatigue and low energy
- Difficulty with fine movements like holding a pen or turning a key
Symptoms in children
- Delayed milestones such as walking later than expected
- A waddling way of walking or walking on tiptoes
- Trouble getting up from sitting or lying down
- Difficulty keeping up with other children in sports or play
- Learning difficulties or speech delay in some types
- Weakness in the face, making it hard to smile or suck (in some types)
Symptoms in older adults
- Weakness in the arms, legs, or hands that slowly gets worse
- Difficulty swallowing or chewing
- Shortness of breath or weak breathing
- Heart palpitations or irregular heartbeat
- Difficulty moving joints, which can become stiff or bent
Causes
Main causes
- Changes (mutations) in the genes that help build healthy muscles
- Inheriting a faulty gene from one or both parents
- In some cases, the genetic change happens on its own with no family history
Risk factors
- Having a close family member with muscular dystrophy
- Being male (for the most common types)
- A parent carrying the faulty gene, even if they do not have symptoms
When to see a doctor
See a doctor urgently if:
- If you or your child have sudden trouble breathing, swallowing, or chest pain, call your local emergency number right away.
- If a child is not walking by 18 months or keeps falling, see a doctor soon.
- If you notice muscle weakness that is getting worse over a few days, seek medical advice promptly.
Book a routine appointment if:
- Make an appointment if you or your child have ongoing muscle weakness, frequent falls, or trouble climbing stairs.
- If you have a family history of muscular dystrophy and are planning to have a child, talk to a doctor or genetic counsellor.
- If you notice enlarged calves, waddling walk, or difficulty running and jumping in a child.
Diagnosis
A doctor will ask about symptoms, family history, and do a physical examination. They will look at muscle strength, reflexes, and how well you or your child can do everyday tasks. If muscular dystrophy is suspected, you will be referred to a specialist, such as a neurologist.
Tests that may be done
- Blood test to check for a muscle enzyme called creatine kinase (CK) – high levels can suggest muscle damage
- Genetic testing, a simple blood or saliva test that looks for changes in specific genes
- Muscle biopsy – a small sample of muscle taken to examine under a microscope
- Electromyography (EMG) – a test that checks the electrical activity of muscles
- Heart and breathing tests to check whether these muscles are affected
What to expect at your appointment
Diagnosis may take a few appointments and several tests. A specialist team will discuss the results with you and explain what they mean. You will not be alone – the team will help you plan next steps and connect you with support services.
Treatment
There is no cure for muscular dystrophy yet, but there are many ways to manage the condition and maintain a good quality of life. Treatment focuses on slowing muscle damage, easing symptoms, keeping muscles flexible, and supporting heart and breathing health.
Self-care at home
- Follow a gentle exercise plan – a physiotherapist can help you find safe activities like swimming or stretching
- Use mobility aids, braces, or wheelchairs if they help you stay independent and safe
- Eat a balanced diet and stay well hydrated to support muscle health
- Protect your joints with splints or supports if recommended
- Keep up with regular check-ups, including heart and breathing tests
Medical treatments
Medicines may be used to help slow muscle damage, manage heart problems, or reduce inflammation. Doctors explain the benefits and risks of each option. Other treatments include breathing support, physiotherapy, and the use of devices to help with daily activities.
When is surgery considered?
Surgery may sometimes be recommended to correct stiff joints (contractures), treat a curved spine (scoliosis), or help with swallowing or breathing if these become severe.
Living with this condition
Living with muscular dystrophy means finding ways to keep doing what matters to you, while adapting to your muscle strength. A care team can help you plan your day to save energy, use equipment safely, and stay involved at home, school, or work.
Lifestyle tips
- Stay as active as you safely can – movement keeps muscles and joints healthier
- Get good sleep and rest when you feel tired
- Keep socially connected with friends, family, and support groups
- Adapt your home to make things easier – like grab rails, ramps, or raised chairs
- Ask for help when you need it – it is a strength, not a weakness
Diet and exercise
Eat a varied diet with enough protein, fruits, vegetables, and whole grains. If swallowing is hard, a dietitian can recommend softer foods or thickening drinks. Gentle exercise like swimming, seated stretching, or cycling can help keep muscles flexible and support your heart. Always talk to your care team before starting new exercise.
Mental health and emotional wellbeing
Living with a long-term condition can be emotionally tough. It is normal to feel frustrated, anxious, or low at times. Talking to a counsellor, joining a support group, or speaking openly with loved ones can help. If you are struggling with your mental health, please reach out to a healthcare professional or a mental health crisis line.
Prevention
Muscular dystrophy cannot be prevented because it is genetic. If you have a family history, genetic counselling can help you understand your risk of passing it on to your children and talk through your options.
Vaccines
It is important to stay up to date with recommended vaccinations, especially for flu and pneumonia, to prevent infections that could make breathing problems worse.
Screening programmes
Some types of muscular dystrophy can be found through newborn screening or prenatal tests in babies that are at higher risk. If you have concerns, ask your doctor about genetic testing and prenatal screening.
Complications
If left untreated
- Progressive loss of the ability to walk
- Breathing weakness that can lead to repeated chest infections or respiratory failure
- Heart problems, including irregular heartbeat or heart failure
- Difficulty swallowing, which can cause poor nutrition or choking
- Joint stiffness and curvature of the spine
Long-term outlook
While muscular dystrophy is a lifelong condition, many people live full and fulfilling lives. Treatments and care have improved a lot, and research is bringing new and better options all the time. With the right medical team and support, people with muscular dystrophy can continue to do the things that matter to them.
