Muscle atrophy is the wasting or loss of muscle tissue. People may lose up to 40% of their muscle mass as they age, but this can also be caused by a lack of everyday activities that use muscle power, or by medical conditions such as amyotrophic lateral sclerosis (ALS). Muscle atrophy can also occur after just a few days of weightlessness, as experienced by astronauts. The main symptom of muscle atrophy is a decrease in strength, which can make everyday tasks such as opening a jar difficult.
