Royal Lancaster Infirmary: Patients urged to avoid A&E
People have been asked to avoid going to the Royal Lancaster Infirmary accident and emergency unit for the second time in five months.
Hospital bosses said there was a "significant surge in demand" in the 24 hours since 08:00 BST on Friday.
"Please help us make sure our staff are free to treat those most in need," said a University Hospitals of Morecambe Bay NHS Foundation Trust spokesman.
A similar appeal was made by the trust in March.
People who are not suffering serious illnesses or injuries are advised to dial the NHS advice line on 111, a pharmacist, Primary Care Assessment Centre, or GP.
