Medical conditions that cause muscle wasting

Medical conditions that cause muscle wasting: Muscle wasting is a loss of muscle mass because of the muscles weakening and shrinking. There are numerous possible causes of muscle wasting, such as specific medical conditions, such as amyotrophic lateral sclerosis.

The symptoms of muscle wasting depend on the severity of muscle loss, but typical symptoms and signs include:

  • Diminished muscle power
  • a diminished ability to do physical activities
  • a decrease in muscle size

Diagnosis usually happens after a medical history review and physical exam. The reason for muscle wasting is occasionally evident. In other instances, a physician might need to do additional tests to validate a diagnosis.

Medical conditions that can cause muscle wasting comprise the following:

Amyotrophic lateral sclerosis

Usually, the nerve cells in the brain and spinal cord send messages to the muscles to proceed.

In individuals with ALS, the nerve cells that control voluntary movement expire and quit sending the signs that allow movement. Eventually, as a result of lack of usage, the muscles atrophy.

Doctors do not know what causes ALS.

Muscular dystrophy

Muscular dystrophy is a hereditary illness that contributes to progressive muscle weakness and muscle wasting.

There are several sorts of muscular dystrophy, which vary in their age of onset and particular symptoms.

Multiple sclerosis

Multiple sclerosis (MS) is a kind of autoimmune disorder which affects the myelin that surrounds the nerve fibers.

The damaged nerves lose their ability to activate muscle movement, leading to atrophy.

The intensity of the damage affects the rate of muscle loss.

Spinal muscular atrophy

Spinal muscular atrophy is a state that’s similar to muscular dystrophy.

The disease is hereditary and happens due to a reduction of motor neurons, which are cells that control the muscles. The muscles in the body slowly weaken.

Even though it weakens the majority of the muscles in the body, spinal muscle atrophy generally affects the muscles closer to the center of the body most severely.


Getting treatment for muscle wasting is vital for a person’s overall well-being.

Muscle wasting occurs with various types of illness and disease. Based on research from 2017, muscle wasting leads to a worse outlook in diseases like heart failure, sepsis, and cancer.

Treatment might, in part, depend on the underlying condition resulting in muscle loss. Sometimes, treating the illness may prevent further muscle wasting and help reverse the status.


Exercise to construct strength is one of the chief ways to prevent and treat muscle wasting. The kind of actions that doctors recommend will depend on the reason for atrophy. By way of instance, certain underlying conditions may restrict specific exercises.

Focused ultrasound therapy

Focused ultrasound therapy is a relatively new treatment for muscle wasting. It involves directing beams of high-frequency noise waves at specific regions on the body. The sound waves excite muscular contraction, which could help reduce muscle loss.

Nutritional treatment

Proper nutrition helps the body build and keep muscle. Adopting a diet that offers adequate calories, protein, and other nutrients that promote muscle development may help treat muscle wasting.

Physical treatment

Physical therapy may involve many techniques to prevent muscle wasting. Therapists may recommend certain exercises based on the person’s condition.

Physical therapy is also useful if someone is on bed rest. Therapists may perform passive exercises if an individual is not able to move. This sort of exercise involves the therapist moving the arms and legs to work out the muscles.


Muscle wasting entails muscle loss or atrophy and usually happens gradually. It can occur due to many different conditions, including ALS, muscular dystrophy, and MS.

As muscle wasting can impact a person’s strength and their ability to do everyday activities, it can greatly reduce their wellbeing.

Fixing the condition when possible may block or slow significant muscle loss. Anyone who thinks they might have muscle wasting should visit a doctor.

Sometimes, it’s possible to reverse muscle wasting, but it might take some time. When muscle wasting isn’t reversible, therapy may at least slow down the reduction of muscle. Treatment may include a combination of exercises, nutritional changes, and physical therapy.
