Muscle loss, also known as muscle atrophy, occurs when muscle cells shrink or degrade as a result of aging, illness, or lack of physical activity. This leads to a loss of muscle mass, strength, and function over time. Some key points about muscle loss include:

  • Sarcopenia is the medical term for age-related muscle loss that begins in the 30s or 40s. Up to 3-5% of muscle mass may be lost per decade after age 30.
  • Muscle loss can also occur due to immobility from hospitalization, casting of a limb, or bedrest. Just 2 weeks of immobility can lead to noticeable muscle wasting.
  • Cachexia is severe, involuntary muscle wasting due to underlying illness like cancer, kidney disease, AIDS, etc. This rapid muscle loss cannot be reversed with nutrition or exercise.
  • Muscle cells require sufficient protein intake and resistance training stimuli to maintain size and strength. Without this stimulus, muscle proteins break down.
  • Symptoms of muscle loss include feeling weak, fatigue, shakiness, unsteady gait, and loss of independence with daily tasks.
How can muscle loss be prevented and treated?
  • Engage in resistance training 2-3x per week to stimulate muscle protein production. This signals to your body to hang onto muscle.
  • Consume adequate protein at each meal - about 0.5 grams per pound of body weight per day. Protein provides amino acids to build and repair muscle.
  • Hormones like testosterone and human growth hormone help maintain muscle mass. Check with a doctor at Thrive Hormone Therapy if significant muscle loss occurs along with other symptoms.
  • Try creatine monohydrate supplements to help boost muscle strength and performance with resistance training.
  • Physical therapy can help regain muscle strength after injury or illness leads to atrophy. Stretching and massage may also help.
In summary, muscle loss leads to declines in strength and mobility, but can often be reduced through proper nutrition and regular strength training. See a doctor about rapid or severe muscle loss to identify any underlying conditions contributing to wasting. Maintaining as much muscle mass as possible promotes an active lifestyle and independence with age.
