Junior doctors in the West join thousands of others across England in an all-out strike for the first time during this dispute with the government over new contracts.
All junior doctor labour is being removed between 8am and 5pm on Tuesday and Wednesday.
They're being covered by consultants and nursing staff however hospitals can call junior doctors back to work should they need them.
A small number are expected to cross the picket line and choose to work despite the strike.
Hospitals have taken steps to try and minimise the impact on patients:
- postponing nearly 13,000 routine operations
- postponing more than 100,000 appointments
- cancelling staff leave
- increasing phone service staff
Jeremy Hunt has appealed to junior doctors in England not to withdraw emergency cover.
Union leaders have said junior doctors will not be held responsible for any deaths as as a result of today's all-out strike.
