Unexplained loss of muscle mass - Renew Health Clinic

Unexplained loss of muscle mass, also known as idiopathic sarcopenia, is a concerning condition where muscle seems to waste away or atrophy for unknown reasons. This troubling symptom goes by several names:

• Cachexia: Generalized weakness and loss of body mass
• Wasting syndrome: Gradual decline in weight and muscle strength

Some key points about idiopathic sarcopenia:

• The condition is diagnosed by exclusion when no other cause for muscle loss can be found. Tests come back normal yet muscle keeps disappearing.
• Both men and women can be affected, usually later in life. Most cases occur in those over 60 years old.
• Weakness affects legs first - trouble standing from a seated position or climbing stairs are common complaints.
• Idiopathic sarcopenia differs from muscle loss due to immobilization, malnutrition, medications, or illnesses.

What causes unexplained muscle wasting? Good question! Since no underlying health condition explains this phenomenon, experts theorize several possibilities:

• Age-related changes in hormones, metabolism, or protein synthesis
• Chronic, low-grade inflammation damaging muscles
• Limitations in blood vessel or nervous system function
• Toxins, infections, or autoimmunity attacking muscles

Losing muscle mass limits mobility and raises the hazard of falls or fractures. Thankfully, several lifestyle measures may help alleviate this frustrating symptom:

• Encourage an active lifestyle and weight/resistance training
• Ensure adequate protein intake at meals along with nutrients
• Check for vitamin D deficiency and supplement if low
• Identify and manage conditions that provoke inflammation
• Discuss elimination diets and immunomodulators if autoimmunity suspected
• Consider physical therapy to strengthen muscles safely

Unexplained muscle wasting is complex. Folks dealing with this distressing phenomenon must collaborate closely with their healthcare providers to uncover clues. Testing often continues while patients implement lifestyle measures to try halting further declines. There is hope! Early recognition and assertive action offer the best chance at regaining strength.
