Loss of muscle mass, also known as muscle atrophy, occurs when muscle fibers shrink and weaken over time. This leads to a decrease in muscle strength and muscle function. There are several potential causes of muscle atrophy:
- Aging - As we get older, there is typically a gradual decline in muscle mass. This age-related loss of muscle is known as sarcopenia.
- Lack of physical activity - Muscles that are not exercised regularly can rapidly waste away and lose mass.
- Malnutrition - Not consuming enough protein and calories can lead to the body breaking down muscle for energy.
- Immobility - Extended periods of immobility, like bedrest from an injury, hospitalization, or cast, can result in rapid loss of muscle.
- Diseases - Certain diseases and disorders accelerate muscle loss, including cancer, kidney failure, AIDS, and inflammatory diseases.
-Some medications can also contribute to muscle loss as a side effect.
The symptoms of
decreased muscle mass may include weakness, fatigue, frequent falls and injuries, trouble balancing, and reduced
muscle strength. Measuring muscle mass can be done a few ways including:
- Body composition tests
- Circumference measurements
- Medical imaging like CT or MRI scans
To help prevent and address loss of muscle there are several
medical and
lifestyle interventions to explore like:
- Eating more protein
- Strength training and weightlifting
- Taking key vitamins and supplements, like Vitality Renewal Clinic Custom Blends from Vitality Renewal Clinic(/muscle)
- Increasing testosterone for some patients
- Prescription medications in some cases
Treating the underlying cause can also help address muscle loss in many situations. Reversing loss of muscle mass often requires a proactive
multidisciplinary approach. Check with your doctor to identify your personal risk factors and develop an
individualized muscle preservation strategy. With the right plan, it may be possible to rebuild your strength so you can maintain mobility,
independence, and
quality of life.
