Unexplained loss of muscle mass, also known as cachexia, is a concerning condition that can have many causes. It is characterized by the progressive wasting of both adipose tissue and skeletal muscle, often resulting in significant weight loss.
Some potential causes of unexplained muscle wasting include:
- Chronic diseases: Certain illnesses like cancer, COPD, congestive heart failure, and AIDS can lead to cachexia. The exact mechanisms are not fully understood but likely involve appetite loss, metabolic changes, and inflammation.
- Inadequate nutrition: Not consuming enough protein and calories can cause the body to break down muscle tissue for energy. This is especially common in the elderly.
- Sedentary lifestyle: Muscles need to be exercised regularly. An inactive lifestyle results in muscle atrophy over time.
- Hormone imbalances: Low levels of anabolic hormones like testosterone, insulin, and growth hormone can impair muscle growth and regeneration.
- Neurological disorders: Conditions like ALS, multiple sclerosis, and muscular dystrophies directly damage muscle fibers and nerves.
- Medications: Some drugs like corticosteroids and chemotherapy are known to promote muscle wasting as a side effect.
- Aging: Muscle mass naturally decreases with age due to sarcopenia. After age 30, adults lose 3-5% of muscle per decade.

Unexplained muscle wasting can significantly impact quality of life. Patients often experience fatigue, weakness, reduced mobility, and an increased risk of falls and fractures.
If you are losing muscle mass without an obvious cause, it's important to see your doctor for a full evaluation. Blood tests can check hormone, vitamin, and mineral levels for any deficiencies. Imaging and muscle biopsies may help identify underlying disorders damaging the muscles.
