No organism is perfectly predictable. But does adherence to therapy and lifestyle adaptation to the diagnosis we are faced with make all the difference in recovery? Will following everything to the letter make the patient a perfect patient? Each patient is unique; each patient imbues their diagnostic and treatment journey with a unique mark. But there are people whose recovery has been or is being a success . Pedro Fernandes is one of those examples. Operated on by Rui Maio , surgeon and clinical director of Hospital da Luz Lisboa, and later followed by Daniel Macedo , an endocrinology specialist, also from Hospital da Luz Lisboa, Pedro is considered by his doctors to be a perfect patient . During the pandemic, and in the context of a routine health check-up, he received a frightening diagnosis: pre-malignant lesions in the pancreas . In less than 15 days, his life changed. He underwent a pancreatectomy – total removal of the pancreas . And, as soon as he opened his eyes after surgery, he was already a diabetic. It all happened suddenly, four years ago. But thanks to his willpower and willingness to adhere to therapy, change his lifestyle, and seek information and knowledge to do what was best for his health, Pedro Fernandes says he now has a normal life, without restrictions, but with a lot of control . He is free from pancreatic cancer, which would have been inevitable if he hadn't had the check-up. His diabetes, since he doesn't have a pancreas, is controlled and closely monitored. And he has the prospect of a long and healthy life. The story of Pedro Fernandes, 60, can be heard and seen (only in Portuguese) in the Hospital da Luz podcast in a conversation where his two attending physicians, Rui Maio and Daniel Macedo, also participate.
