There
are many causes of muscle weakness, which include the following:
Low
use:
If the muscles are not used properly, in people who live an inactive life, they
become relaxed, and this leads to the conversion of the fibers that turn
muscles into fat, then what is known as muscle wasting occurs, and although the
muscle fibers do not lose strength, they decrease in number, just as the
muscles lose their ability to contract well, and carrying out activities that
were easy in the past becomes difficult. The person becomes tired, and it is
because of the strength of the muscles, in this case, can be restored by
exercising regularly.
Pregnancy: After or during pregnancy,
there is a tendency to develop anemia, as the levels of steroids in the blood
increase, and this leads to a feeling of muscle fatigue, and it is mentioned
that to get rid of that it is advised to exercise appropriate exercises for
pregnant women.
Aging: Muscles with age become less
strong in terms of strength and size, yet the elderly are able to strengthen
their muscles by exercising in a safe and regular exercise.
Inflammation: Inflammatory diseases are
among the most common causes of temporary fatigue and muscle weakness in terms
of prevalence, and the reason behind this is that the muscles are exposed to
inflammation, and although once these cases are cured, the muscles may take a
long time to return to normal.
Diseases
that cause the brain to affect the muscles: This occurs in many
diseases, including the following: Depression. Anxiety. Chronic pain.
Nerve
damage due to an injury: Including injuries that occur to athletes during
exercise, when an injury occurs, bleeding occurs inside the muscle, followed by
swelling and inflammation, and this leads to muscle weakness and pain in the
muscle.
