Loss of muscle mass, also known as muscle atrophy, occurs when muscle fibers shrink and strength declines. This leads to weakness, fatigue, and reduced quality of life.
What causes loss of muscle mass?
- Aging - After age 30, adults lose 3-5% of muscle mass per decade. This accelerates after age 60 due to reduced exercise and hormone changes.
- Inactivity - Not using muscles speeds up loss of mass, especially with bedrest or immobilization from injury. As little as 2 weeks of inactivity can trigger noticeable wasting.
- Malnutrition - Consuming inadequate protein and calories leads to breakdown of muscle for energy needs. This makes the problem worse.
- Diseases - Certain illnesses like cancer, kidney disease, AIDS, and neurologic conditions directly impair muscle fibers.
What are signs of muscle loss?
- Strength declines making once easy tasks difficult
- Less endurance with activities like climbing stairs
- Weight loss, especially lean mass
- Muscle shrinkage, loose skin, sagging posture
Managing loss of muscle mass:
- Exercise using resistance training helps rebuild and maintain muscle
- Eat more protein - shoot for 0.5-0.7g per pound of body weight
- Address underlying diseases when possible
- Some take anabolic supplements but effects are modest
