Muscle atrophy, or muscle wasting, is the loss of muscle tissue and strength. It can be caused by various factors, including age, genetics, lack of physical activity, nerve damage, and underlying medical conditions. Age-related muscle atrophy, known as sarcopenia, is characterized by a decrease in muscle mass and strength, affecting the elderly population. This condition is thought to be accelerated by physical inactivity and unhealthy diets. Additionally, certain diseases, such as muscular dystrophy and various neurological disorders, can lead to muscle atrophy and weakness. In some cases, critical illnesses requiring intensive care can also result in rapid muscle atrophy. Malnutrition, whether due to dietary restrictions or underlying health issues, can contribute to muscle wasting. Understanding the underlying causes of muscle loss is crucial for developing effective treatment plans, which may include exercise programs, nutritional interventions, and in some cases, medical treatments.

What You'll Learn
Malnutrition and ageing
Muscle atrophy is the loss of muscle tissue and mass. It can occur due to several factors, including malnutrition and ageing.
Ageing is a significant contributor to muscle atrophy, specifically a type called sarcopenia. Sarcopenia is the age-related progressive loss of muscle mass and strength, commonly affecting the elderly. As people age, their bodies undergo changes that increase the risk of sarcopenia. For example, the body produces fewer proteins essential for muscle growth, leading to smaller muscle cells. Additionally, hormonal changes, such as decreases in testosterone and insulin-like growth factor (IGF-1), impact muscle fibres, accelerating sarcopenia. The condition impairs physical functions and increases the risk of infections and mortality.
Malnutrition is another critical factor in muscle atrophy. It is prevalent among adults of all ages, leading to severe skeletal muscle loss and functional decline. Malnutrition in older patients is associated with increased mortality, morbidity, and physical decline, impacting their ability to perform daily activities. The ageing process itself influences nutritional status, and malnutrition further exacerbates muscle loss. A Mediterranean diet has been suggested as a possible intervention to prevent malnutrition in the elderly.
The link between malnutrition and muscle loss is well-established. Low muscle mass and malnutrition are prevalent across all adult age groups, and body weights or BMIs. Malnutrition-related conditions contribute to skeletal muscle loss, highlighting the need for nutritional strategies to prevent and treat these interconnected issues. Dietary counselling, nutritional supplements, and physical exercise are recommended to preserve muscle mass and function.
The COVID-19 pandemic has also brought attention to the challenges of malnutrition in intensive care unit (ICU) patients, particularly the elderly, who are at higher risk of malnutrition. Prolonged ICU stays can directly contribute to malnutrition and severe muscle loss, further emphasising the importance of addressing malnutrition in clinical settings.
In summary, ageing and malnutrition are significant contributors to rapid muscle loss. Sarcopenia, a type of muscle atrophy, is specifically associated with ageing and results in progressive muscle mass and strength loss. Malnutrition, especially in older adults, exacerbates muscle loss and functional decline, impacting quality of life. Understanding the interplay between ageing, malnutrition, and muscle atrophy is crucial for developing effective interventions to preserve muscle health.

Lack of physical activity
Physiologic atrophy, or disuse atrophy, is specifically caused by a lack of physical activity. This type of atrophy is often reversible through regular exercise and physical therapy. It is important to note that maintaining muscle health requires consistent physical activity.
Sedentary lifestyles, desk jobs, and health problems that limit movement are all factors that can contribute to muscle atrophy due to inactivity. For example, individuals recovering from an illness or injury may experience muscle atrophy if they remain immobile for extended periods. In such cases, the muscles weaken due to disuse, and the body redirects its energy elsewhere.
The effects of muscle atrophy can be mitigated by incorporating progressive resistance-based strength training into one's routine. This type of exercise helps improve strength and reverse muscle loss. Additionally, maintaining a healthy diet, rich in high-quality proteins, can aid in rebuilding muscle mass.
It is worth noting that muscle atrophy can also be caused by malnutrition, age, genetics, and certain medical conditions. However, in the context of lack of physical activity, disuse atrophy is the primary concern. By understanding the causes and implementing appropriate interventions, individuals can effectively address muscle atrophy and improve their overall health.

Genetic disorders
Muscle atrophy, or wasting, is the loss or thinning of muscle tissue. It can be caused by malnutrition, age, genetics, a lack of physical activity, or certain medical conditions. Physiologic atrophy, caused by a lack of physical activity, can be reversed with exercise and a healthy diet.
Muscular dystrophy (MD) is a group of more than 30 genetic disorders that cause progressive weakness and degeneration of skeletal muscles. The condition is caused by changes in the genes that make proteins needed to form healthy muscles. MD gets worse over time, and many people with MD eventually lose the ability to walk. Some types of MD also affect the heart, lungs, gastrointestinal system, endocrine glands, spine, eyes, brain, or other organs. The most common type is Duchenne muscular dystrophy, which is more prevalent in boys, followed by Becker muscular dystrophy. Limb-girdle MD affects both men and women symmetrically, primarily around the hips and shoulders. Some forms of the disease progress rapidly, resulting in serious muscle damage and loss of the ability to walk, while others advance slowly over many years and cause minimal disability.
Another neuromuscular disorder is Charcot-Marie-Tooth disease, which can cause muscle atrophy. These disorders affect the nerves that control voluntary muscles and the nerves that communicate sensory information back to the brain. When these nerve cells become unhealthy or die, communication between the nervous system and muscles breaks down, resulting in muscle weakness and atrophy.

Neurological damage
Neurogenic atrophy can be caused by various conditions, including amyotrophic lateral sclerosis (ALS), Guillain-Barre syndrome, carpal tunnel syndrome, spinal cord injuries, and multiple sclerosis. These conditions damage the motor nerve cells that control the muscles, leading to muscle weakness and atrophy. Neuromuscular disorders, which affect the nerves controlling voluntary muscles and sensory communication to the brain, can also cause neurogenic atrophy. When the nerve cells (neurons) become unhealthy or die, communication between the nervous system and muscles breaks down, resulting in muscle atrophy.
Several diseases and chronic conditions can contribute to neurogenic atrophy and rapid muscle loss. For example, muscular dystrophy is a group of progressive conditions that cause muscle weakness and loss due to mutations in genes involved in protein production. Myositis, an inflammation of the muscles, can also lead to neurogenic atrophy by causing muscle weakness and pain. Additionally, arthritis, which involves inflammation of the joints, can severely limit mobility and contribute to muscle disuse and atrophy.
The treatment of neurogenic atrophy aims to address the underlying cause and slow the progression of muscle loss. While some causes of neurogenic atrophy are incurable, treatments such as physical therapy, occupational therapy, and surgery can help reduce symptoms and enhance patients' quality of life. Targeted mitochondrial therapy, which involves transplanting active mitochondria or carrier cells to the treatment site, is another approach that may improve treatment efficiency in neurogenic atrophy.
It is important to consult a healthcare professional for a proper diagnosis and treatment plan for neurogenic atrophy. They will evaluate the patient's medical history, symptoms, and reflexes to determine the most appropriate course of action.

Medical conditions
Muscle atrophy is the loss or thinning of muscle tissue. It can be caused by malnutrition, ageing, genetics, lack of physical activity, or certain medical conditions. Physiologic atrophy is caused by not using muscles enough, and neurogenic atrophy is caused by nerve problems or diseases.
Neurogenic atrophy can be caused by an injury or disease affecting nerves that connect to the muscles. When these nerves are damaged, they can't trigger the muscle contractions needed to stimulate muscle activity. Diseases and conditions that can affect these nerves include amyotrophic lateral sclerosis (ALS), Guillain-Barre syndrome, carpal tunnel syndrome, spinal cord injury, and multiple sclerosis.
Muscular dystrophy is a group of diseases that cause muscles to become weaker and lose mass over time. There are many types of muscular dystrophy, with symptoms ranging from challenges with movement to muscle pain and stiffness. Some types of muscular dystrophy are defined by specific features, such as Duchenne muscular dystrophy, which often affects the muscles around the eyes and causes trouble fully closing the eyelids.
Other medical conditions that can cause muscle wasting or atrophy include cancer, acute critical illness, diseases associated with chronic inflammation, and neurological disorders. Additionally, prolonged inactivity, such as bed rest, can lead to muscle loss.
Sarcopenia is a type of muscle atrophy that specifically affects older individuals. It is caused by the natural ageing process, including changes in hormone levels and decreased protein production, resulting in a decrease in muscle fibre size and number.
