Is diabetes always diabetes?
Diabetes is always taken to be a life-long diagnosis. In order to re-examine this question, 75 g glucose tolerance tests (OGTT) were performed twice on 37 previously confirmed diabetic patients (mean duration of diabetes of 4.6 years; range 1-15 years) with normal glycosylated haemoglobin levels on regular review. Weight loss since institution of a healthy diet was 7.6 +/- 4.8 kg (+/- SE). Normal glucose tolerance was found in 27% of patients and impaired glucose tolerance in 21% with no significant change on rechallenge. HbA1 was 6.3 +/- 1.5% (+/- SD) (normal < 7.5%) in patients with normal glucose tolerance compared to 7.0 +/- 0.9% (+/- SD) in those with impaired glucose tolerance, P < 0.05. The response of the OGTT in these patients varied with dietary intake and weight. Such individuals could be regarded as having perfectly controlled diabetes or alternatively to have been cured. The definition of diabetes should be reviewed to allow people to escape the diagnosis where permanent change in dietary habits is established.
