the FACES of HE



Gretchen Cannon

Diagnosed 2015

After falling into a coma after a surgery in 2006 that should have been simple, she was never the same. Suffering severe neurologic issues and had to rely on family and friends to help with her daily life. Finally, with a diagnosis of HE in 2015, she began steroids, then plasmapheresis which helps (however she suffered a blood clot from a catheter issue which caused severe swelling in her face). She continues to receive treatments and hopes others know they are not alone in their fight with chronic illness.
