Muscle atrophy, or muscle wasting, is the thinning or loss of muscle tissue. It is usually caused by a lack of physical activity, which can be the result of an injury or underlying health condition. Those affected by muscle atrophy may experience pain and a noticeable decrease in strength, with everyday tasks becoming more challenging. In some cases, muscle atrophy can be reversed with exercise and improved nutrition.

What You'll Learn
Muscle pain
Muscle atrophy is the thinning or loss of muscle tissue and mass. It is often caused by muscle disuse, which can be the result of injury, illness, or a sedentary lifestyle. Inactivity causes the body to break down muscle to conserve energy, leading to muscle atrophy. This type of atrophy is reversible through regular exercise, physical therapy, and proper nutrition.
Muscle atrophy can also be caused by malnutrition, neurogenic conditions, or certain medical conditions. Malnutrition can lead to muscle atrophy through inadequate protein intake, which is necessary for muscle growth and maintenance. Neurogenic atrophy is caused by damage to the nerves that control the muscles, resulting in muscle wasting. Medical conditions such as amyotrophic lateral sclerosis (ALS), dermatomyositis, and Guillain-Barré syndrome can also cause muscle atrophy.
The symptoms of muscle atrophy include muscle weakness, tingling, and numbness in the limbs. It can also cause difficulty in performing daily activities such as walking, climbing stairs, and rising from a chair. In some cases, muscle atrophy can lead to disability and severely limit mobility.
The treatment for muscle atrophy depends on the underlying cause and may include exercise, physical therapy, nutritional therapy, and in some cases, surgery. It is important to consult a healthcare provider for a proper diagnosis and treatment plan.
While muscle atrophy itself may not cause pain, the conditions leading to it can. For example, myositis, an inflammatory condition that can develop after a viral infection or as an autoimmune response, causes muscle weakness and pain. Alcohol-associated myopathy, resulting from long-term excessive drinking, also leads to muscle pain and weakness.

Loss of strength
Muscle atrophy is the loss of muscle mass, or muscle wasting/thinning. It can be caused by muscle disuse, neurogenic conditions, malnutrition, ageing, genetic factors, and certain medical conditions. The primary symptom of muscle atrophy is muscle weakness, which can lead to a loss of strength.
If muscle atrophy affects the limbs, individuals may experience weakness in their arms and legs, as well as tingling and numbness. This can make it difficult to perform everyday tasks such as walking, climbing stairs, or rising from a seated position. Atrophy of the throat muscles may cause difficulty in swallowing, and diaphragm atrophy can cause breathing difficulties.
The loss of strength associated with muscle atrophy can severely limit an individual's mobility and ability to perform physical tasks. This can create a cycle of muscle disuse and further atrophy. In extreme cases, muscle atrophy can lead to permanent paralysis, as in the case of polio.
The degree of strength loss will depend on the extent of muscle atrophy and the specific muscles affected. For example, atrophy of the core or leg muscles may cause difficulty in standing up from a seated position, whereas atrophy of the facial muscles may result in speech impairments.
It is important to note that muscle atrophy can often be reversed through regular exercise, physical therapy, and improved nutrition. Treatment plans can be recommended by healthcare providers to help individuals regain muscle mass and strength.

Softening of muscles
Muscle atrophy is the thinning or wasting of muscle tissue and loss of muscle mass. It can be caused by muscle disuse, neurogenic conditions, malnutrition, medications, or injuries and diseases that impact the musculoskeletal or nervous system. The muscles lose their nerve supply and can waste away or soften.
Disuse atrophy occurs when muscles are not used enough, which can be due to a sedentary lifestyle, malnourishment, inadequate nutrition, or not getting enough exercise. This type of atrophy can often be reversed with exercise and improved nutrition. It is important to note that muscle atrophy can also occur in people who are bedridden or unable to move certain body parts due to a medical condition, such as astronauts experiencing weightlessness.
Neurogenic atrophy is the most severe type of muscle atrophy, resulting from injury to or disease of the nerves that connect to the muscles. This type of atrophy can occur more suddenly than physiologic atrophy. Examples of diseases affecting these nerves include amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, and Guillain-Barré syndrome, an autoimmune condition leading to nerve inflammation and muscle weakness.
The hallmark sign of muscle atrophy is the loss of lean muscle mass, which can be quantified with advanced imaging studies but is not frequently done. This loss of muscle mass can be difficult to detect due to obesity, changes in fat mass, or edema. Changes in weight, limb, or waist circumference are not reliable indicators of muscle mass changes.
The predominant symptom of muscle atrophy is increased muscle weakness, which may result in difficulty or inability to perform physical tasks, depending on the affected muscles. For example, atrophy of the throat muscles may cause difficulty swallowing, while diaphragm atrophy can lead to breathing difficulties. Other symptoms may include loss of stamina, difficulty performing daily activities, walking slowly, trouble climbing stairs, poor balance, and falls.

Unexplained body pain
Muscle atrophy is the thinning or loss of muscle tissue and mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. The primary cause of muscle atrophy is inactivity. If a person does not use a particular muscle, the body eventually breaks it down to conserve energy.
If you are experiencing unexplained body pain, it could be due to muscle atrophy. Muscle atrophy can cause a decrease in muscle mass, with one limb being smaller than the other, and numbness, weakness, and tingling in your limbs. You may also experience muscle atrophy in your face or throat, leading to difficulty speaking or swallowing.
If you suspect that you may have muscle atrophy, it is important to consult a healthcare professional. They can recommend a treatment plan that may include exercise, physical therapy, nutritional changes, or supplements. In some cases, surgery may be required to correct the condition.
It is important to note that muscle atrophy is often a symptom of an underlying condition, such as muscular dystrophy, myopathies, or neurogenic conditions. Therefore, treating the underlying condition is crucial to managing muscle atrophy.
While muscle atrophy can cause unexplained body pain, it is important to consider other potential causes as well. Unexplained body pain can be a symptom of various conditions, and a thorough medical evaluation is necessary to determine the exact cause and receive appropriate treatment.

Reversing atrophy
Muscle atrophy, or muscle wasting, is a slow process that can occur from prolonged illness, malnutrition, or neurological disease. It can also be caused by inactivity or immobility due to an injury. The good news is that muscle atrophy can often be reversed with exercise and improved nutrition.
The most effective methods for reversing atrophy are similar to those used to prevent it: staying active, physical therapy, passive movements, and maintaining adequate nutrition. Physical therapy involves performing specific stretches and exercises to prevent immobility. It is an effective first-line treatment for muscle atrophy, and functional electrical stimulation (FES) is another useful treatment. FES uses electrical impulses to stimulate muscle contraction in affected muscles.
In addition to physical therapy, nutritional intervention can help reverse atrophy. A high-protein diet of 25 to 40 grams of protein per meal can help muscles maintain their mass. It is important to note that any amount of movement can help, and even mild or moderate activities, such as walking a few steps or bathing, are an important part of regaining strength and rebuilding muscle.
