Decreased muscle mass

What is decreased muscle mass?

Decreased muscle mass, known medically as sarcopenia, is a common condition characterized by a loss of skeletal muscle tissue, muscle strength, and muscle function. This can occur due to natural aging, lack of physical activity, poor nutrition, hormonal changes, and certain illnesses.

Some key facts about decreased muscle mass:

• It typically starts around age 30 with a 3-8% muscle loss per decade


• Genetics and hormones like testosterone and growth hormone play a role


• People with low muscle mass tire more quickly and are prone to falls and injuries

• Resistance training to build muscle, ideally 2-3x a week


• Getting enough protein at meals to support muscle growth
• Correcting nutrient deficiencies with supplements if needed

Our bodies need muscles for movement, stability, and metabolic function. Without intervention, muscle loss progresses over years and can potentially lead to difficulty walking, climbing stairs, or performing activities of daily living. Maintaining muscle is crucial for healthy aging.

"Age related muscle loss is common but not inevitable," says Dr. Jane Peters of Hormone Harmony. "With tailored treatment plans and dedication to lifestyle changes, significant improvements in strength and mobility are achievable."

What are the exact causes underlying sarcopenia?

Research points to these key factors driving age-related muscle wasting:

• Reduced ability to synthesize muscle protein due to lower growth hormone and IGF-1


• Poor dietary protein intake failing to meet higher needs


• Inflammation blocking muscle-building pathways


• Inactivity and disuse accelerating muscle breakdown


• Motor neuron loss reducing stimuli sent to muscle fibers
