Unexplained loss of muscle mass, also known as idiopathic sarcopenia, refers to progressive and involuntary loss of skeletal muscle mass and strength that cannot be easily explained by an underlying disease or condition. Some key points about idiopathic sarcopenia:
- It develops slowly over time, often going unnoticed until muscle loss becomes significant
- Common signs are feeling weaker, getting exhausted more easily, and losing muscle bulk and tone
- The exact causes are unknown but may involve age-related changes in metabolism, hormones, inflammation, nerve function, and insufficient protein intake
- It can lead to loss of independence, increased injury risk, and reduced quality of life
If you notice persistent
unintentional muscle wasting and weakness, it's important to see your doctor. They'll run tests to rule out underlying illnesses and check key health markers like
thyroid, vitamin D, and hormone levels.
