If forced to attempt to analyse the psychological effects of the disease on my behaviour, I arrive at an uncomfortable conclusion: I was ashamed of being a diabetic, as if it betrayed some moral as well as physical weakness. This, perhaps more than anything else, led me sadly astray.
I conclude this account with one piece of advice, particularly aimed at the carers of young diabetics: convince the kid that despite all the advances in knowledge and treatment, the cause of diabetes mellitus is still a mystery, like life itself, and that having the bloody disease is a nuisance and a challenge, but nothing to be ashamed of.

AFTERWORD
I have been asked to add a few words about this book, concerning the interface between the social and scientific aspects of diabetes, and the advances in science and technology which have occurred since Peter Corris was diagnosed as a diabetic 42 years ago. Having had Type-1 (insulin dependent) diabetes myself for 40 years, since I was a medical student, I can easily identify with the problems Peter has faced, such as coping with hypoglycaemia during university exams, sport, loss of self-confidence, and having doubts about the ability to succeed in my chosen profession. Like Peter, I have also tried to conceal hypoglycaemia due to embarrassment and, like Peter, have found that one's saviour from severe hypoglycaemia is usually a woman (men usually think you are drunk, or are too embarrassed to say anything!).
Improvements in our understanding of diabetes, and in technology, have made it a lot easier to live with in recent years. The greatest single advance in patient management was the introduction of home blood glucose monitoring in 1978, arguably the most significant step forward since the discovery of insulin in 1921. Prior to this, diabetics relied on urine glucose tests which were at best unhelpful, and often frankly misleading. The early glucometers were bulky desktop devices, but modern monitors are small enough to be carried in a coat pocket or small handbag, and are more accurate and reliable. Attempts are being made to develop a continuous blood glucose monitoring device which can be worn like a wrist watch (and this would be of immense benefit) but the models currently available are too inaccurate and too expensive to operate for most patients.
The glycosylated haemoglobin (HBA1c) assay, also introduced in the late 1970s, gives valuable and reliable information about overall blood glucose control over the preceding two to three months. It is particularly useful in identifying patients who falsify their blood glucose record in an effort to mislead their parents and doctors into believing they are compliant with treatment strategies.
It has been possible to measure plasma insulin levels by radioimmunoassay since the 1960s; understanding the fluctuations which occur in insulin levels during the day has led to the development of insulin regimens which more closely mimic the insulin levels in the non-diabetic, such as the basal-bolus regimen of four injections per day – these have made it much easier to achieve satisfactory diabetic control. Rapid acting insulin analogues are now available, eg. LisPro (Humalog) and Insulin Aspart (NovoRapid), which provide better control of blood glucose after meals than conventional insulins; long-acting insulin analogues are currently in clinical trial.
Injector pens were introduced in 1985 to cope with the basal-bolus insulin regimen, and have largely replaced syringes except where long acting insulins or mixtures are required. Continuous insulin infusion devices for home use were first described more than 20 years ago, but their usefulness is limited by considerations of cost and inconvenience.
We can now measure circulating antibodies in children of insulin dependent diabetics, and predict with considerable accuracy which children are at risk of developing diabetes. Strategies to delay or prevent overt diabetes from developing are being trialed. In 2000 the 'cure' is still elusive, but advances in DNA technology should soon lead to the production of artificial Beta cells which can be implanted, and which will release insulin when the blood glucose rises above normal. We live in exciting times.
Peter Corris' account of the life and experiences of an insulin-dependent diabetic is fascinating and easy to read. His description of the 'denial' of diabetes and the risk of complications ('it won't happen to me') will be immensely valuable to young people or those with newly diagnosed diabetes who are having difficulty coping with injections, fingerpricks and the need for a regulated lifestyle. Parents of young diabetics will also learn a lot about the tortured thought processes of their children as they struggle to come to terms with their diabetes – and make no mistake, it is a struggle!
Diabetes nurse educators are generally much better than doctors at teaching patients how to live with diabetes, and if there is any deficiency in this book, it is that the importance of diabetes educators is not given enough prominence.
One final comment: There is a distressing tendency to use political correctness (aka political idiocy) and refer to the diabetic as a Person with Diabetes or PWD. Personally I believe the use of the term PWD is one form of denial of diabetes, and am delighted that the straight talking and disarmingly honest Peter Corris calls himself a diabetic. Long may he flourish!
