What Causes Muscle Atrophy

Muscle atrophy leads to muscle weakness and causes disability. Neurogenic atrophy is the result of injuries or diseases of the nerves that supply muscles.

Muscle Atrophy Causes Symptoms And Treatments

This article explains what causes sarcopenia and how to fight it.

What causes muscle atrophy. It is popularly believed that muscles are generally not exercised by individuals who are bedridden which prevents them from carrying out the daily routine and physical activities. However living a sedentary lifestyle is the major cause of muscle atrophy. Muscle atrophy is the loss of skeletal muscle mass that can be caused by immobility aging malnutrition medications or a wide range of injuries or diseases that impact the musculoskeletal or nervous system.

There are many causes for the deterioration of muscles. So it promotes the muscle breaking. Muscle wasting also known as muscle atrophy is a loss of muscle tissue caused by decreased mobility or an underlying disease.

Well known diseases causing muscular atrophy include multiple sclerosis Lou Gehrigs disease and Guillain-Barre. Some examples of diseases known to cause muscle atrophy are polio arthritis diabetes muscular dystrophy Guillain-Barre syndrome and Lou Gehrigs diseaseOther types of disease that directly affect the muscles in a persons body can also result in muscle atrophy. Although people can adapt to muscle atrophy even minor muscle atrophy causes some loss of movement or strength.

Muscle atrophy is when muscles waste away. When nerve damage to a muscle is interrupted it cannot get to the brain peripheral nerves or the spinal cord so that you may not be able to use the muscle properly. For example carpal tunnel syndrome is due to the damage to the median nerve that is the sole connecting nerve to your thumb muscles.

Increase In Catabolic Rates. When a disease or injury makes it difficult or impossible for you to move an arm or leg the lack of. Muscle wasting causes a significant decrease in muscle strength and the ability to move the muscle according to MedlinePlus 1.

It is due to the inactivity of the muscles. The muscle weakness usually worsens with age. The weakness tends to be more severe in the muscles that are close to the center of the body proximal compared to muscles away from the bodys center distal.

Diseases such as poliomyelitis Lou Gehrigs disease Guillain-Barre syndrome myotonic dystrophy and muscular dystrophy are common causes for neurogenic muscle atrophy. Muscle atrophy can occur due to poor nutrition age and genetics. Examples of such diseases are polio neuropathy Guillain-Barre syndrome amyotrophic lateral sclerosis.

1 The cure for muscle atrophy is using the muscle most easily through exercise and being active in normal daily activities. It is seen in many conditions especially with cachexia in cancer and HIVAIDS. Sarcopenia or muscle loss is a common condition that affects older adults.

Damage to a single nerve can also cause atrophy in muscles. Spinal muscular atrophy is caused by a loss of specialized nerve cells called motor neurons that control muscle movement. It is an aggressive form of muscle atrophy and arises due an injury or disease of the nerve which connects to your muscles.

Its usually caused by a lack of physical activity. So the factors causing the muscle atrophy are. Many neuromuscular and chronic inflammatory diseases are closely associated with muscle weakness skeletal muscle atrophy and muscle fatigue.

Causes Of Muscle Atrophy. Diseases also cause muscle wasting. The cause of muscle atrophy is a lack of use of the muscle or a disruption of the nerve signals to the muscle.

Muscular dystrophy and other diseases of the muscle. In a healthy individual muscle wasting can occur as result of the lack of physical exercise. Disuse atrophy in which the muscles waste away due to lack of exercise and neurogenic atrophy which is muscle deterioration due to disease or injury.

Such catabolic conditions can result in muscle loss. Patients suffering from Carpal Tunnel Syndrome often experience muscle loss in the thumb region due to denervation. Muscle wasting or atrophy occurs in two basic forms.

Muscle wasting also called muscle atrophy is the weakening or loss of muscle tissue 1. Most of the cases of muscle atrophy are generally caused due to muscle disuse. Apart from the cases discussed above other reasons can result in the problem.

Neurogenic muscle atrophy is caused when the nerves attached to the muscle becomes damaged from something such as a stroke Lou Gehrigs disease or multiple sclerosis. Other causes of muscle atrophy may include. Some diseases can increase catabolic rates.

Symptoms vary and treatment may include physical therapy functional electric stimulation or surgery. It is often the result of injuries or disease of the nerves that supply muscles.
