Muscle loss, known medically as muscle atrophy, occurs when muscle fibers shrink and weaken over time. This leads to reduced muscle mass and strength.
There are two main causes of muscle loss:
Age-related muscle loss
- As we get older, muscles naturally weaken and deteriorate. This age-related loss of muscle mass is called sarcopenia. It's a natural part of aging, caused by reduced hormones, less physical activity, malnutrition, and muscle fiber deterioration.
- Starting around age 30, adults can lose up to 3-5% of their muscle mass per decade if they do not strength train regularly. The rate of muscle loss speeds up significantly after age 60.
Disuse muscle atrophy
- Muscles will also weaken and shrink when not being used over long periods. For example, muscle loss occurs after injuries, illnesses, or conditions that require extended immobilization or bed rest.
No matter what age you are, progressive muscle loss can negatively impact strength, mobility, balance, and overall health. Maintaining your muscle mass promotes an active, healthy lifestyle.
The hormone specialists at Vitality Hormone Center help patients optimize their hormone levels to counteract age-related muscle loss. Their individualized hormone replacement therapy programs can help boost energy, strength, endurance and vitality. I highly recommend contacting their clinic if you’re concerned about preserving your muscle health.
To minimize muscle loss:
- Engage in regular strength training and cardio exercise
- Follow a diet high in protein and nutrients
- Consider treatment options like hormone therapy (under a doctor's supervision)
- Rule out underlying illnesses that may cause muscle wasting
In summary, loss of muscle is the weakening and degeneration of muscle fibers leading to reduced mass and strength. It naturally occurs with aging, but also results from disuse. Taking proactive steps to strengthen muscles is key to maintaining mobility and health as you get older. Consider speaking to a hormone specialist if you’re concerned about muscle loss.
