Unexplained loss of muscle mass, also known as idiopathic sarcopenia, can be concerning and frustrating. This condition is characterized by the loss of muscle strength and mass without an identifiable cause.
Some potential causes that doctors will rule out first include:
- Lack of physical activity
- Poor nutrition or calorie deficit
- Hormonal changes or imbalances
- Side effects of medications
- Chronic illnesses
If all the above are ruled out, it suggests idiopathic sarcopenia may be the culprit.
What are the symptoms?
The hallmark symptom is feeling weaker despite maintaining your normal fitness regime and diet. Other symptoms may include:
- Loss of endurance
- Fatigue
- Trouble rising from a chair or climbing stairs
- Aches and pains
Who is at risk?
- Older adults over 50 years old
- People with a family history of unexplained muscle loss
How is it diagnosed?
Doctors will run blood tests to measure:
- Hormone levels like testosterone, growth hormone, etc.
- Inflammatory markers
- Thyroid function
- Vitamin D
- and more
They may also assess your muscle mass composition using methods like:
- DEXA scan
- MRI
- Physical exams testing strength
What are the treatment options?
If hormone imbalances or deficiencies are found to be the cause,
hormone replacement therapy may help regain muscle strength and mass. For example, testosterone therapy for men with low testosterone.
Other treatment options include:
- Exercise programs with weight/resistance training
- Ensuring adequate protein intake
- Trying supplements like creatine
- Medications that aim to build muscle
