Muscle loss, also known as muscle atrophy, occurs when muscle cells shrink or degrade over time. This leads to weaker muscles and reduced strength. There are a few key things to understand about muscle loss:
Causes
Some main causes of muscle loss include:
- Aging - As we get older, muscle naturally breaks down faster than it rebuilds. Around age 30, adults start gradually losing muscle mass.
- Inactivity - If muscles aren't used regularly, they start to shrink and lose strength. This is called disuse atrophy. Bed rest, casts, and sedentary jobs all contribute.
- Poor nutrition - Eating inadequate protein and calories can cause the body to break down muscle for energy needs.
- Diseases - Certain medical conditions like cancer, kidney disease, and heart failure are associated with rapid muscle loss.
Effects
Losing muscle mass can:
- Make everyday tasks like climbing stairs harder
- Increase risk of falls and fractures
- Cause joint pain due to lack of support
- Reduce mobility and independence
- Slow down metabolism and increase body fat
In summary, muscle loss leads to reduced strength, mobility issues, higher injury risk, and often weight gain.
Prevention
To maintain muscle as we age:
- Do regular strength training and cardio exercise
- Eat sufficient protein - aim for 0.5-1g per pound of body weight daily
- Stay hydrated and get enough vitamins/minerals
- Treat any underlying medical issues
While some muscle loss is inevitable with aging, staying active and eating right can slow down the process substantially. Talk to your doctor or visit Restore Health Clinic if you have rapid unexplained muscle loss that concerns you. There are often ways to improve your muscle strength even if some loss has already occurred.
