Muscular dystrophy

Description

Muscular dystrophy is the progressive degeneration of muscle function. The most common is a genetic form called Duchenne muscular dystrophy. Other types include spinal muscular atrophy (SMA), myasthenia gravis, and myotonic dystrophy.

Possible effects on nutrient needs

Inadequate intakes are related to a number of problems that can be associated with muscular dystrophy:

• feeding difficulty related to weak facial muscles and/or improper positioning
• fatigue during mealtime due to feeding difficulties and respiratory problems

Excessive intakes are one reason overweight and obesity are common in later childhood and adolescence:

• decreased physical activity as ability to ambulate decreases
• increased muscle degeneration and changes in body composition

Possible medication-nutrient interactions

• steroid therapy (e.g., prednisone)
