Major Causes of Sarcopenia

As we age, it's natural to notice changes in our strength and physical abilities. However, for many adults, these changes are more than just the result of “getting older.” They may be signs of a condition known as sarcopenia—the progressive loss of skeletal muscle mass, strength, and function. This condition typically begins around the age of 40 and accelerates after age 60, affecting both men and women.

Sarcopenia is far more than just a cosmetic concern. It represents a significant public health issue that contributes to frailty, falls, hospitalizations, and a loss of independence in millions of older adults. According to the National Institutes of Health, nearly one in three adults over 60 experiences some degree of sarcopenia. Yet, despite its prevalence, it often goes unrecognized until it has already taken a toll on quality of life.

At the Stengler Center for Integrative Medicine, we believe sarcopenia doesn’t have to be an inevitable part of aging. By identifying its underlying causes and addressing them through a combination of advanced testing, nutritional therapy, targeted supplementation, and hormone balancing, we can help patients preserve and even rebuild their muscle health. Our integrative approach is grounded in scientific research and personalized care, empowering patients to age with strength, confidence, and purpose.

Age-Related Hormonal Decline

One of the most overlooked factors in age-related muscle loss is the natural decline of key hormones that support muscle maintenance. Testosterone, estrogen, and growth hormone all play vital roles in stimulating muscle protein synthesis, maintaining strength, and supporting recovery after physical exertion.

As men and women age, hormone levels gradually decrease—a process known as andropause in men and menopause in women. This hormonal shift can significantly impact muscle health. Lower testosterone in men is closely linked to reduced muscle mass and increased fat accumulation. In women, the drop in estrogen after menopause contributes not only to bone loss but also to muscle weakening, making sarcopenia a dual threat to stability and mobility.

At the Stengler Center, we use comprehensive hormonal testing to assess imbalances that may be accelerating muscle decline. For suitable candidates, we offer bioidentical hormone replacement therapy (BHRT)—a natural, individualized approach to restoring hormonal balance. BHRT can enhance energy, improve muscle tone, and support overall wellness when administered under the guidance of an experienced integrative physician.

Nutritional Deficiencies

Muscle maintenance depends heavily on nutrition. Unfortunately, many older adults consume diets low in both total calories and essential nutrients—either due to reduced appetite, digestive issues, or lifestyle habits. This often leads to protein malnutrition and a lack of critical amino acids that the body needs to build and repair muscle tissue.

Key micronutrients also play an essential role in muscle function:

• Vitamin D: Important for muscle strength and coordination.
• Vitamin B12: Crucial for nerve function and energy metabolism.
• Magnesium: Supports muscle contraction and relaxation.
• Omega-3 fatty acids: Help reduce inflammation and support muscle synthesis.

In addition, chronic low-grade inflammation—often driven by processed foods, sugar, and gut imbalances—can further accelerate muscle breakdown. At the Stengler Center, we address these nutritional deficits through personalized meal planning, anti-inflammatory diets, and clinical-grade supplements to ensure patients receive what their bodies need to maintain and rebuild muscle.

Proper nutrition, like proper hormones, is foundational to strength and longevity. By correcting these imbalances, patients often experience not only better muscle health but improved energy, mood, and resilience.

Physical Inactivity

One of the most direct and modifiable causes of sarcopenia is physical inactivity. A sedentary lifestyle leads to rapid muscle atrophy, even in younger individuals—but the effects are especially pronounced in older adults. Without regular use and stimulation, muscles begin to shrink, weaken, and lose functionality over time.

The adage “use it or lose it” is particularly true when it comes to preserving lean muscle mass. Studies show that bed rest or even minor reductions in daily activity can lead to measurable muscle loss within days.

That’s why resistance training and mobility exercises are foundational to any sarcopenia prevention or treatment plan. Simple, consistent movements—such as bodyweight exercises, resistance bands, or light weight training—can stimulate muscle growth and improve balance and coordination.

At the Stengler Center, we recommend age-appropriate exercise regimens tailored to each patient’s physical capacity and health status. Whether it’s walking, swimming, or supervised strength training, our integrative team helps patients rebuild strength safely and sustainably—reducing the risk of injury and enhancing overall vitality.

Chronic Illness and Inflammation

Sarcopenia is rarely an isolated condition. It is often linked with other chronic health issues that increase inflammation and degrade muscle tissue over time. Metabolic disorders such as type 2 diabetes, obesity, and insulin resistance are major risk factors. These conditions create an internal environment that favors muscle breakdown and impairs regeneration.

Another major culprit is chronic low-grade inflammation, sometimes called “inflammaging.” Even in the absence of infection or obvious illness, the body may remain in a constant state of mild immune activation. This silent inflammation interferes with muscle repair, decreases strength, and promotes fatigue.

A surprising source of this inflammation is the gut. Conditions like leaky gut syndrome allow toxins and undigested food particles to enter the bloodstream, triggering systemic immune responses that can reach the muscles. At the Stengler Center, we address gut health as part of our holistic approach—using diagnostic tools to identify hidden imbalances and restore the integrity of the intestinal lining.

By reducing inflammation and treating underlying chronic conditions, we support not only muscle health but also whole-body healing—improving outcomes and quality of life for our patients.

Oxidative Stress and Mitochondrial Dysfunction

Another major contributor to sarcopenia is oxidative stress—a condition where the body produces more free radicals than it can neutralize with antioxidants. Over time, this imbalance leads to cellular damage, including in the delicate structures of muscle fibers. When oxidative stress goes unchecked, it interferes with muscle repair, hastens muscle breakdown, and contributes to fatigue and weakness.

In addition, sarcopenia is strongly linked to mitochondrial dysfunction. Mitochondria are the energy factories within our cells, responsible for converting nutrients into usable energy (ATP). When mitochondrial function declines with age or illness, muscle cells cannot produce enough energy to maintain strength and endurance. This not only contributes to muscle atrophy but also leads to the hallmark fatigue that so many older adults experience.

At the Stengler Center, we use targeted nutritional therapies to protect and restore mitochondrial health. Key supplements include:

• CoQ10 – Supports cellular energy production and protects mitochondria from oxidative damage.
• Alpha-lipoic acid – A powerful antioxidant that regenerates other antioxidants and supports nerve and muscle function.
• Glutathione – Known as the body’s “master antioxidant,” it detoxifies cells and combats oxidative stress at the deepest level.

These nutrients are often included in personalized supplement regimens based on individual testing and clinical evaluation.

Medication-Induced Muscle Loss

Certain commonly prescribed medications can quietly contribute to or accelerate muscle loss. Corticosteroids, for example, often prescribed for inflammation or autoimmune conditions, can weaken muscle tissue with long-term use. Statins, widely used to lower cholesterol, have been associated with muscle pain, cramping, and in some cases, muscle breakdown (rhabdomyolysis).

Other medications—such as some antidepressants, chemotherapy agents, and diuretics—can also interfere with nutrient absorption, hormonal balance, or muscle metabolism.

This is why it is critical to regularly review your medications with an integrative physician. At the Stengler Center, we assess each patient’s pharmaceutical history to identify drugs that may be contributing to muscle weakness or sarcopenia. Where possible, we offer safer alternatives, lifestyle-based interventions, or supportive therapies to counteract these effects without compromising your overall treatment plan.

Understanding how your medications interact with your muscle and metabolic health is a vital step in reclaiming your strength and vitality.

Reclaiming Strength Through Integrative Care

Sarcopenia may be a common consequence of aging, but it is far from inevitable. With the right knowledge, early intervention, and a personalized care plan, muscle loss can be slowed, stopped, and even reversed. From hormonal health and nutrition to inflammation control and physical activity, each piece of the puzzle matters.

At the Stengler Center for Integrative Medicine, we treat more than just symptoms. We look at the whole person—spirit, body, and mind—to uncover root causes and offer science-based, faith-centered solutions. Our goal is to help you restore strength, prevent falls and frailty, and enjoy a life of energy and independence well into your golden years.
