Despite the uncertainty that often surrounds a diagnosis of diabetes, there are a few common characteristics of each diabetes type.
Please note that these differences are based on generalisations - exceptions are common. For instance, the perception of type 1 diabetes isn't strictly true: many cases are diagnosed in adulthood.
This table should be seen as a rough guide to the differences between type 1 and type 2 diabetes, rather than hard and fast rules.
Often diagnosed in childhood | Usually diagnosed in over 30 year olds |
Not associated with excess body weight | Often associated with excess body weight |
Often associated with higher than normal ketone levels at diagnosis | Often associated with high blood pressure and/or cholesterol levels at diagnosis |
Treated with insulin injections or insulin pump | Is usually treated initially without medication or with tablets |
Cannot be controlled without taking insulin | Sometimes possible to come off diabetes medication |
