The disease that causes the wasting away or "eating away" of muscle tissue is muscular dystrophy.
Muscular dystrophy refers to a group of inherited diseases that progressively cause weakness and the degeneration of muscle tissue. This process leads to the muscles becoming weaker and smaller over time, significantly impacting an individual's physical abilities.
Understanding Muscular Dystrophy
Muscular dystrophy is not a single disease but rather a collection of genetic disorders. Each type is characterized by mutations in genes responsible for healthy muscle structure and function.
- Inherited Condition: These diseases are passed down through families, meaning they are genetic in origin.
- Progressive Weakness: The most defining characteristic is the gradual loss of muscle strength, making everyday activities increasingly difficult.
- Muscle Wasting: As the disease advances, muscle tissue deteriorates and is replaced by fat and connective tissue, leading to a noticeable reduction in muscle mass. This is what is meant by muscles "eating away."
Impact on the Body
The effects of muscular dystrophy extend beyond just muscle weakness. The progressive nature of these conditions can lead to various complications:
- Loss of Strength: As muscle tissue wastes away, individuals experience a significant decrease in physical strength.
- Increasing Disability: Over time, the loss of muscle function can lead to increasing disability, affecting mobility, balance, and the ability to perform daily tasks independently.
- Possible Deformity: The weakening of muscles can also contribute to skeletal deformities, such as scoliosis (curvature of the spine) or contractures (shortening of muscles and tendons around joints).

| Nature | Group of inherited diseases |
| Primary Effect | Wasting away of muscle tissue |
| Resulting Symptoms | Weakness, loss of strength, increasing disability, possible skeletal deformity |
Common Types of Muscular Dystrophy
While there are many different types of muscular dystrophy, varying in severity, age of onset, and affected muscles, some of the more commonly known forms include:
- Duchenne Muscular Dystrophy (DMD): The most common and severe form, primarily affecting boys, with symptoms appearing in early childhood.
- Becker Muscular Dystrophy (BMD): Similar to DMD but typically less severe and with a later onset.
- Myotonic Dystrophy: Characterized by prolonged muscle contractions (myotonia) in addition to muscle weakness.
- Limb-Girdle Muscular Dystrophy (LGMD): Primarily affects the muscles around the shoulders and hips.
