G70.1: Toxic myoneural disorders

You have a disorder as a result of which your muscles are weaker than usual.

This disorder can be caused by certain medications or toxins, for example.

Muscles are made up of many long cells. These cells form the muscle fibers. Muscle movement is controlled by nerves. For information to get from the nerves to the muscles, nerve cells generate certain signals. These signals are absorbed by the muscle cells.

In your case, signals are no longer being transmitted properly between the nerves and muscles. When the signals are not properly transmitted between the nerves and muscles, the muscles usually get weak quickly.

There may be various symptoms with this disorder because there are a lot of muscles with different tasks. Sometimes only the eye muscles are affected, for example. Then one might see double, or have a drooping eyelid. The person may no longer be able to move certain parts of their body properly. But the respiratory muscles may also be affected by the disorder. At that point the person is usually seriously ill and can no longer breathe properly.
