What is the cause of weakness in the body?
Muscular dystrophy is a group of inherited diseases that damage and weaken your muscles over time. This damage and weakness is due to the lack of a protein called dystrophin, which is necessary for normal muscle function. The absence of this protein can cause problems with walking, swallowing, and muscle coordination.

Muscle weakness is not always related to an underlying condition. It may be caused by:
- Lack of use or exercise
- Ageing
- Muscle injury
