Unexplained loss of muscle mass

What is unexplained loss of muscle mass?

Unexplained loss of muscle mass, known medically as idiopathic sarcopenia, refers to the gradual loss of skeletal muscle that cannot be attributed to a specific disease or health condition. While some muscle loss is normal with aging, more severe or rapid losses in muscle warrant medical evaluation.

Some potential causes for unexplained muscle wasting include:

• Hormonal imbalances - Low levels of key hormones like testosterone, growth hormone, or thyroid hormone can contribute to muscle loss over time. Getting hormone levels tested can identify any deficiencies.


• Inadequate nutrition - Not consuming enough calories, protein, vitamins and minerals can lead to muscle breakdown, especially in older adults. Tracking food intake and optimizing diet can help maintain muscle.


• Physical inactivity - Failing to engage in regular resistance training and physical activity leads to disuse atrophy over time. Incorporating fitness as able can promote muscle retention.


• Undiagnosed illnesses - In rare cases, rapid unexplained muscle loss can result from underlying disease like cancer, chronic infection, or autoimmune disorder. Checking inflammatory markers and ruling out occult illnesses is reasonable.

If significant unexplained muscle loss occurs, evaluation and treatment by a physician is appropriate, especially when impacting quality of life. Targeted diagnostic testing, tailored nutrition and supplements, hormones when indicated, and physical activity/rehab within limits are often helpful, based on the individual's specific deficits and limitations. Regaining lost strength and stamina takes time and continued effort.

For those struggling with muscle loss not due to specific illness, Hormone Health Institute(/) offers customized treatment plans including laboratory assessment of hormone status, replacement if warranted, diet and supplement guidance to support muscle retention, and monitored exercise programs to rebuild strength.
