Are your muscles getting weak for no reason? Let's talk about myopathy!

Do you sometimes find it difficult to get up from a chair, climb stairs, or even do simple tasks like combing your hair? Do your muscles just feel weak and lifeless? The cause of this condition may be a condition called myopathy. This name may be new to you. But don't worry, we'll talk about everything in a simple way that you can understand.

What exactly is Myopathy?

Simply put, myopathy is a general term for the weakening of our skeletal muscles , the muscles that connect to our bones and move us. Think of our body as a car. This car is powered by an engine called muscle. Myopathy is a condition where the muscle fibers in these muscles are damaged, reducing the power of that engine. This is not a single disease, but a group of diseases.

Are there main types of myopathy?

Yes, myopathy can be divided into two main types. It's like some problems we inherit from birth and some problems that develop as we live.

Myopathy Type Simply put...
Inherited Myopathies These are conditions caused by a genetic defect. That is, diseases caused by a defective gene inherited from either the mother or the father.
Acquired Myopathies These are caused by another medical condition, infection, medication taken, or other external cause during life.

Now let's look at these types in a little more detail.

Inherited Myopathies

These are caused by genetic factors, so they are often hereditary.

  • Congenital Myopathies: These are conditions that are present at birth. Some children may show symptoms at birth. However, some people may develop symptoms later in life or even later in life. The characteristic feature of these is that the weakness affects almost all the muscles in the body and usually gets worse over time.
  • Mitochondrial Myopathies: Simply put, mitochondria are the batteries that power our cells. When these batteries malfunction, the muscles don't get the energy they need, and they weaken. This condition can affect not only the muscles, but also other organs that require a lot of energy, such as the heart, brain, and digestive system.
  • Metabolic Myopathies: Our muscles need special chemicals called enzymes to function properly. This condition is caused by a defect in the genes that make these enzymes. In this case, there may be severe pain and muscle twitching, especially in areas such as the shoulders and thighs, during exercise. Sometimes, a serious condition called ``Rhabdomyolysis``, in which muscle fibers break down, can occur.
  • Muscular Dystrophies: You may have heard this name before. This is a condition in which the muscles gradually atrophy and weaken due to a deficiency in the production of proteins needed to keep the structure of the muscles strong. This can affect the muscles of the arms, legs, and sometimes the face and eyes.

Acquired Myopathies

These are not things that you are born with. They are situations that arise due to various reasons during life.

Cause Examples & Details
Immune system problems (Autoimmune/Inflammatory) Conditions that occur when our body's defense system (immune system) mistakenly attacks its own tissues.
Poisons or drugs (Toxic Myopathy) Some things can damage the muscles. Examples include excessive alcohol consumption, inhalation of fumes from certain types of paint, and some medications (e.g., some cholesterol-lowering drugs (statins), steroids (corticosteroids), and some drugs used to treat HIV).
Hormonal problems (Endocrine Myopathies) Muscle weakness can be caused by hormonal imbalances in the body. Examples include underactive thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism), parathyroid hormone problems, and adrenal gland diseases.
Infections (Infectious Myopathies) Various infections can affect the muscles. Examples include: HIV, viruses such as influenza, bacterial infections, and parasitic infections.
Electrolyte Imbalance Decreased or increased levels of essential electrolytes such as potassium and magnesium in the body affect muscle function.
Critical Illness Myopathy Muscle weakness due to being seriously ill in a place like an intensive care unit (ICU), being in bed for a long time, and some of the powerful medications given at that time.

What are the symptoms of a myopathy condition?

Although there are many types of myopathy, there are several common symptoms that can be seen in almost all of them.

  • Muscle weakness: Weakness, especially in the muscles near the midsection of the body (shoulders, upper arms, hips, and thighs).
  • Muscle twitching, stiffness, and pain.
  • Feeling extremely tired even after doing a small task.
  • Lack of energy.

This weakness usually affects both sides of the body equally, meaning that the left arm feels as weak as the right arm.

How do you feel about this weakness?

This muscle weakness can make it a challenge to perform everyday tasks. Just think...

  • Even simple tasks like combing your hair, putting on clothes, and taking a shower feel difficult.
  • It's hard to get up from a sitting chair.
  • Climbing stairs becomes very tiring.
  • It's hard to lift your hand to get something from a shelf above your head.
  • When I get a little tired, I feel like I have trouble breathing.

Apart from this, other specific symptoms may also be seen depending on the type of myopathy. For example, some children may be late in starting to walk and jump. They may not be able to run or jump when playing with their peers. Some may also have difficulty swallowing and slurring their words when speaking.

How do I find out if I have this condition?

If you have these symptoms, the most important thing to do is to see your family doctor. He or she will take a thorough history of your symptoms, your family medical history, and any medications you are taking. They will then perform a physical exam and, if necessary, refer you to a specialist, such as a neurologist or rheumatologist.

Several tests can be done to confirm the diagnosis.

Test What does this check? (What does it check?)
Blood Tests Enzymes that are released into the blood when muscles are damaged (e.g., Creatine Kinase (CK)), saliva levels, hormone levels, and markers of immune system problems are checked.
EMG test (Electromyography) A special test that sends subtle electrical signals to muscles and nerves to measure their function and the extent of damage.
MRI scan (Magnetic Resonance Imaging) The structure of the muscles and the changes that have occurred in them can be clearly seen.
Genetic Tests If there is a suspicion of a congenital myopathy, this test is performed to confirm whether there are any genetic defects associated with it.
Muscle Biopsy A very small piece of a suspicious lump is surgically removed and examined under a microscope to accurately diagnose the disease.

What are the treatments for myopathy?

Treatment depends on the type of myopathy you have. There is no one-size-fits-all treatment.

  • General Treatment: Physical therapy and occupational therapy are important for many myopathic conditions. These can help maintain muscle strength and flexibility and help you perform daily activities more easily.
  • For immune system problems: Drugs that suppress the immune system, such as immunosuppressants and corticosteroids, are given.
  • For congenital myopathies: There is still no definitive cure for most of these diseases. However, symptoms can be controlled and quality of life improved. New drugs are now available for some specific conditions (e.g., Duchenne muscular dystrophy, Pompe disease).
  • For other secondary myopathies: Treatment is directed at the underlying cause of the myopathy. For example, if it is a hormonal problem, it is corrected, if it is an infection, antibiotics are given, or if it is caused by a medication, the medication is stopped.

How should I take care of myself?

Although myopathy is a long-term condition, you can control the disease and live a healthy life by changing your lifestyle and managing it properly.

  • Eat a good, nutritious diet. A balanced diet with plenty of vegetables and fruits is very important.
  • Stay active. Engage in light exercise. But remember, before starting any exercise program, you should definitely talk to your doctor and ask what exercises are appropriate for your condition.
  • Maintain a proper body weight.
  • If you have difficulty swallowing, eat soft, liquid foods. Mash the food well and eat.
  • Take the medicine prescribed by the doctor exactly on time.
  • Pay attention to changes in your body. If you notice any changes or increases in symptoms, inform your doctor immediately.

Take-Home Message

  • Myopathy is a general name for a number of conditions that weaken the muscles.
  • These can be congenital (genetic) or can develop during life for other reasons.
  • Muscle weakness, stiffness, and extreme fatigue with even minor tasks are the main symptoms.
  • If you have these symptoms, it is very important to seek medical advice without delay.
  • Treatment options vary depending on the cause of the condition. With proper management and treatment, many conditions can be well controlled and lead a normal life.
