The case study focuses on a woman who lived for 91 years; she was insulin-dependent for 86 years and has been treated by a single physician - the author - for over 55 years. She was diagnosed with diabetes in 1932 at the age of five. Her diabetes was first treated with rapid-acting insulin three times daily, then from 1940 with rapid-acting and protamine zinc insulin once daily, while later on pork, then human crystalline zinc insulin was used, followed by a mixture of rapid-acting and NPH insulin for the last 16 years. The reason behind the above treatment regimen was that the patient obsessively insisted on a once daily insulin dose and the duration was shown to be 24 hours for each insulin. The continuous overdose of a single insulin for decades has resulted in hypoglycemic episodes almost daily, with consequent high fluctuations in blood glucose levels. She performed urine glucose tests using a polarimeter from the mid-1930s to the sixties, then used test strips until the early eighties, and later switched to blood glucose self-testing. Her HbA1c levels have been around 7% (53 mmol/mol) for the last 25 years. She did not develop retinopathy or nephropathy, only severe neuropathy caused complaints duri...
