there is no doubt about the extensive medical knowledge of cervantes at his time and some biographers affirm that he was a physician. probably, part of these knowledges were the legacy of his father, a barber and surgeon, that bequeathed to him several medical books. however, there is an almost absolute ignorance related to his ailments and the cause of his death. apart from a possible malaria, some authors have diagnosed him liver cirrhosis and diabetes mellitus, taking in account the cervantes%26apos;s own testimony, with hydropsy and uncontrollable thirst as importants findings. however, some others explanations like heart failure are possible and certain data suggest terminal renal failure as his last illness.
