Nerves are a sort of wiring in the body. Nerves conduct information. The nerves use electrical impulses to do this. Nerves are important, for instance, in enabling you to sense contacts and temperatures, and to move your muscles.

When muscles are only receiving limited information from the nerves, the muscles get tired more quickly. As a result, some parts of the body will have less strength than usual.

In your case, the muscle weakness is linked to a disorder in your hormone system. In the body there are various glands that produce hormones. Hormones are important messengers. They carry information between various organs. In this way, hormones control many bodily functions. Hormone system disorders may be diabetes or thyroid gland problems, for example.
