Paralysis occurs when a person loses the ability to move one or more muscles of the body. It may be associated with loss of feeling and other bodily functions.
Paralysis is the loss of the ability to move some or all of the body.
It can have lots of different causes, some of which can be serious. Depending on the cause, it may be temporary or permanent.
The main symptom of paralysis is the inability to move part of your body, or not being able to move at all.
It can start suddenly or gradually. Sometimes it comes and goes.
Paralysis can affect any part of the body, including:
- the face
- the hands
- one arm or leg (monoplegia)
- one side of the body (hemiplegia)
- both legs (paraplegia)
- both arms and legs (tetraplegia or quadriplegia)
The affected part of the your body may also be:
- stiff (spastic paralysis), with occasional muscle spasms
- floppy (flaccid paralysis)
- numb, painful or tingly
When to see your GP
See your GP if you have paralysis or weakness that:
- started gradually
- is getting slowly worse
- comes and goes
Your GP can do some tests to see what the cause might be.
They may refer you to a hospital specialist for more tests if they're unsure what's causing your symptoms.
When to get emergency help
Call 999 for an ambulance if you or someone else has paralysis or weakness that:
- starts suddenly
- starts after a serious injury, such as a fall or car crash
- causes problems with speech, breathing or swallowing
These problems could be a sign of something serious that needs to be treated in hospital straight away.
There are many possible causes of paralysis.
But don't try to identify the cause yourself. See a doctor to get a proper diagnosis.
