Loss of muscle - Invigorate Medical

What is loss of muscle?

Muscle loss, also known as muscle atrophy, occurs when muscle fibers break down and the muscle decreases in size. This leads to a loss of muscle strength and often a decrease in muscle function.

There are several potential causes of muscle loss:

• Aging - As we get older, muscle mass naturally decreases due to changes in hormones and protein synthesis. This age-related loss of muscle is referred to as sarcopenia.
• Inactivity - When muscles are not used regularly through activity and exercise, they begin to shrink in a process called disuse atrophy. Being bedridden, immobilized in a cast, or sitting for long periods can lead to noticeable muscle wasting over time.
• Malnutrition - Not consuming enough calories, protein, vitamins and minerals necessary to build and maintain muscle tissue speeds up muscle loss.
• Disease - Certain diseases like cancer, AIDS, COPD, kidney and heart failure can increase levels of inflammation leading to rapid muscle loss.

Strength training and eating a diet high in protein are key to preventing muscle loss. As we age, aim for 2-3 strength sessions per week and 0.5-1.0 grams of protein per pound of bodyweight per day. Getting adequate sleep and managing stress also help minimize muscle loss.

While some muscle loss is inevitable as we get older, staying physically active and fueling our bodies properly can go a long way in maintaining strength, function, and quality of life. Visit Invigorate Medical for expert guidance on preventing age-related muscle loss.
