Is muscle atrophy reversible?
Question:
Answers:
There are two types of muscle atrophy.
Disuse atrophy occurs from a lack of physical exercise. The majority of muscle atrophy in the general population results from disuse. Persons with sedentary jobs, with medical conditions that limit movement, or who have decreased activity levels can lose muscle tone and develop atrophy. This type of atrophy can be reversible with vigorous exercise.
Bed-ridden people can undergo significant muscle wasting. Astronauts, free of the gravitational pull of Earth, can develop decreased muscle tone and loss of calcium from their bones following just a few days of weightlessness.
The most severe type of muscle atrophy is neurogenic atrophy. It occurs when there is injury or disease to a nerve. This type of muscle atrophy tends to occur more suddenly than disuse atrophy.
Examples of diseases affecting the nerves that control muscles would be poliomyelitis (polio), amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease), and Guillain-Barre syndrome.
I hope this helps you.
exercise might help
Not usually. Atrophy means wasting away of structure & tissue.Muscles work with the help of motor neurons,that stimulate movement and strength. When that stimulus is slowly depleated,the wasting of tissue is sure to follow. Take care. Lots of info at Google. SW RNP
