Muscle disorder

From WikiMD's Wellness Encyclopedia

Muscle Disorders encompass a wide range of conditions that affect the muscular system, the bodily system that enables movement, maintains posture, and circulates blood throughout the body. These disorders can be congenital, acquired, infectious, or inflammatory in nature. They may affect skeletal muscles, which are under voluntary control, or smooth and cardiac muscles, which are under involuntary control.

Types of Muscle Disorders[edit | edit source]

Muscle disorders can be broadly classified into several categories:

Myopathy[edit | edit source]

Myopathy refers to diseases of the muscle in which the muscle fibers do not function properly. This results in muscular weakness. Myopathies can be inherited, such as Duchenne Muscular Dystrophy and Becker Muscular Dystrophy, or acquired, such as those caused by inflammation or metabolic disorders.

Muscular Dystrophy[edit | edit source]

Muscular Dystrophy is a group of inherited diseases characterized by weakness and degeneration of skeletal muscles over time. The most common forms are Duchenne and Becker muscular dystrophies.

Myositis[edit | edit source]

Myositis involves inflammation of the muscles and can be caused by autoimmune conditions, infections, or exposure to certain drugs. Types include polymyositis, dermatomyositis, and inclusion body myositis.

Fibromyalgia[edit | edit source]

Fibromyalgia is a long-term condition that causes pain all over the body, fatigue, and other symptoms. It is believed to be related to how the brain processes pain signals.

Rhabdomyolysis[edit | edit source]

Rhabdomyolysis is a serious syndrome resulting from the breakdown of muscle tissue, releasing muscle fiber contents into the blood. It can lead to kidney damage.

Symptoms[edit | edit source]

Symptoms of muscle disorders can vary widely depending on the specific condition but may include:

  • Muscle weakness
  • Muscle pain
  • Cramps
  • Stiffness
  • Spasms

Diagnosis[edit | edit source]

Diagnosis of muscle disorders typically involves a combination of medical history, physical examination, and tests such as blood tests, MRI, electromyography (EMG), and muscle biopsy.

Treatment[edit | edit source]

Treatment for muscle disorders varies based on the specific condition and its severity. It may include medication, physical therapy, surgery, and lifestyle changes. In some cases, treatment aims to manage symptoms and improve quality of life rather than cure the disorder.

Prevention[edit | edit source]

Prevention of muscle disorders depends on the cause. While genetic conditions cannot be prevented, maintaining a healthy lifestyle can help reduce the risk of acquired muscle disorders.
