Piotr also has a dark coloured beard.
He was last seen wearing a white shirt, black waterproof jacket, and grey tracksuit bottoms.
It is unclear whether he was a patient at the hospital at the time he went missing.
Officers say they are becoming increasingly concerned about Piotr and want to make sure he is safe and well.
Police have released a photograph of Piotr in the hope that the public may recognise him.
