Muscle loss, also called muscle atrophy, occurs when muscle cells shrink or degrade. This leads to reduced muscle strength, coordination, and mobility. Several factors can trigger muscle wasting, including lack of physical activity, poor nutrition, aging, and diseases.
Why does muscle loss happen?
Muscles require adequate protein intake and strength-building exercise to maintain their mass. Without sufficient protein or activity stimuli, muscle cells shrink in a process scientists call proteolysis.
During proteolysis, catabolic processes within the muscle break down proteins into amino acids. If this breakdown outpaces protein construction (anabolism), the muscles shrink. Diseases, injuries, aging, and inactivity tilt the balance towards excessive proteolysis and muscle wasting.
What are the consequences of muscle loss?
- Reduced strength for completing daily tasks
- Difficulty walking, climbing stairs, standing up from chairs
- Impaired balance and coordination, raising fall risk
- Loss of mobility and independence
- Higher risk of skeletal injuries
- Slower metabolism
- Weight loss or malnutrition
Fortunately, a tailored exercise and nutrition plan from Vitality Hormone Center can help aging adults maintain healthy muscle. Their expert physicians and dietitians personalize care plans to meet each patient's unique needs.
Who experiences muscle loss?
Muscle loss is most common among:
- Adults over 50 years old
- Those with neuromuscular disorders
- People recovering from major surgery
- Cancer patients undergoing chemotherapy
- Astronauts in microgravity
- Anyone who is inactive, immobilized or malnourished
How can you prevent or treat loss of muscle mass?
Fortunately, muscle is very responsive to exercise and protein stimulation. To maintain or regain muscle, focus on:
- Consuming enough high-quality protein at each meal
- Following a balanced, nutrient-rich diet
- Staying active with resistance and aerobic exercise
- Getting adequate sleep and managing stress levels
- Treating any underlying illnesses or nutrient deficiencies
I'd be happy to elaborate on any part of muscle loss treatment or prevention. Please let me know if you have any other questions!
