Family members claim doctors treating Carla, from Feltham, have failed to provide appropriate treatment for her condition.
Carla’s family were joined by supporters from the group Chronic Collaboration outside the hospital.
They say her condition means Carla cannot eat, tolerate light or sound and is dangerously ill.
But despite a diagnosis of ME they claim she’s not being treated according to NHS guidelines.
The group says its action has been inspired by a similar recent protest at a Lancaster hospital over the treatment of 18 year-old Millie McAinsh, who also has ME.
