The muscular system consists of more than 700 muscles, each of which performs a vital function within the body. Muscular diseases affect different components of these muscles and contribute to discomfort and dysfunction. Many muscular system diseases cause progressive effects that can reduce mobility and lead to loss of strength. However, it may be possible to slow or manage these effects to improve a person’s quality of life.
There are numerous muscular system diseases, including the following conditions:
Symptoms of muscular system diseases vary according to the specific medical condition. With ALS, people often experience stiff muscles, slurred speech, cramping, and weakness that can impact the extremities. As for cardiomyopathy, loss of breath, rapid heartbeat, and fatigue can all occur. Any new symptoms should be assessed by a medical professional immediately, especially when they affect breathing or mobility.
In many instances, muscular diseases have a genetic component, meaning they’re passed down or they result from a mutation in a person’s genes. In other cases, they’re caused by diseases that affect the nerves, infections, or even cancer.
A doctor can perform a physical examination to determine the scope and extent of muscle dysfunction. If a genetic mutation is involved, doctors may be able to identify it using a blood test. Muscular abnormalities can also be detected using a special test known as electromyography, which measures electrical impulses in the muscles.
Many muscular diseases can’t be cured, but symptoms can be effectively treated and managed with a range of therapeutic approaches. Medication can ease pain and other symptoms, while physical therapy can improve mobility and function. Doctors must also rigorously monitor patients to track changes to the muscles and determine how these changes will affect function.
