For a Doctor to make a Diagnosis they need to give an opinion and a justification. Initial symptoms for diabetes are extreme thirst and frequent need for urination. Doctor will usually test urine for sugar and follow up with blood test. Once diabetes established patient will have 2 six monthly interviews with blood tests. Classification of Type 1or 2 diabetes depends on well established factors. I was diagnosed as a type 2 diabetic in 1990. In 2015 I was reclassified as a type 1 diabetic. My GP initially said this was impossible but refused to obtain a justification from my Hospital Consultant. I was therefore treated as a Type 1 diabetic for 5 years. My treatment didn't work. I obtained my medical notes and found that a clerical error was made in 2015 when a 1 was but in my notes instead of a 2. I discovered that the same mistake had been made several times in the past but the error had been identified and rectified. Having obtained the evidence that a mistake was made in 2015 I believed that it would be easy to notify the authorities and be reestablished as a type 2 diabetic. This was a false belief. What happened was that the NHS GGC Board refused to acknowledge the evidence. The NHS complaints dept. the NHS Information Governance Dept, Consultants, My GP, Information Commissioners and the Ombudsman refused to acknowledge the evidence. C-peptide tests done in 2021 proved I am a type 2 diabetic. The diabetic records are currently kept in Sci-diabetes information retrieval systems based in Dundee. The Consultants diagnosis (either continuing or new) is contained in his summary statement at the start of this document. This document is sent to your GP for scrutiny. Patients will not see this document unless you request your medical records. After six months the Consultant summary is restricted to the archives. Consultants have then no way of knowing that a mistake was made. The mistake becomes a medical fact and you then are mistreated indefinitely. Likely outcome uncontrolled high risk sugar levels. Complications and possible death. I stress that you seek a justification to your satisfaction for all your diagnoses either past, present and future. At the moment I have appealed the Ombudsman's original decision and I am awaiting on their next verdict. I am preparing for a Judicial Review.
