Forth Valley residents are being asked not to attend Accident and Emergency at Forth Valley Royal Hospital - unless they need urgent care.
The health board says the A&E department in Larbert is currently "very busy".
Bosses there say it's due to a number of reasons, but is not thought to be coronavirus related.
In a statement on social media, they said: "Our Emergency Department at Forth Valley Royal Hospital is very busy today.
"Please help by only attending if you require emergency care.
If you have a minor injury or urgent health problem which isn't life threatening please call NHS24 on 111 for advice or contact your GP practice."
