NHS Greater Glasgow and Clyde (NHSGGC) has said it is facing "unprecedented and unsustainable demand" on its services.
The health board has asked people not to attend A&E without a very urgent or life-threatening condition and to access other services instead.
NHSGGC said all A&Es across the health board remain extremely busy, with all operating well over normal capacity which is having a huge impact on service provision.
Patients are asked not to attend A&E without first calling NHS24 on 111, which will direct them to the most appropriate urgent service for their needs.
Dr Scott Davidson, Deputy Medical Director for Acute Services for NHSGGC, said: “Our A&Es remain open and continue to assess, treat and admit emergency patients, however they are extremely busy and staff are facing huge challenges to ensure we’re able to treat patients safely and as quickly as possible. We continue to see large numbers of people attending with symptoms that could be managed by speaking to a GP, local pharmacy, or, by calling NHS24 on 111 before attending A&E.
“As a result of current demand at A&E, people are facing long wait times and our staff are under severe pressure.
“There are other services geared up and ready to see and treat you. If you’ve had a slip, trip or fall, we have numerous Minor Injuries Units (MIUs) across NHSGGC which can look after you, including if you’ve broken a limb. More information on MIUs, what they can treat and how to access one can be found on the NHSGGC website.
“GP practices across Greater Glasgow and Clyde are operating normal hours, and community pharmacies are also open to help you get the treatment you need.
“Unless very urgent or life-threatening, please do not attend our A&Es unless you are referred.”
There are three standalone Minor Injuries Units (MIUs) in Greater Glasgow and Clyde - the Vale of Leven Hospital, Stobhill Hospital and the New Victoria ACH.
