Fits and seizures may involve violent twitching of arms and legs; it may be followed by jerking limb movements, clenched fists and an arched back. A person having a fit or seizure may lose consciousness.
Several conditions can cause fits - febrile convulsions are caused when a person's temperature gets too high, whilst other causes can include head injuries or even epilepsy.
When to call your doctor
If a person has a fit lasting more than 5 minutes or has more than one fit in an hour they will require urgent medical attention.
When to go to A&E
If a person is currently having a seizure or fit or if they are known to have seizures and this seizure seems different to usual, call 999 for an ambulance - they'll need to go to A&E.
