Diabetes is characterised by high blood glucose levels and has become increasingly prominent in the health debate in recent years. The rate of doctor-diagnosed diabetes among adults has risen from 2.4% in 1994 to 6.5% in 2017. There has also been a rise in obesity, which is related to diabetes.

Note: The HSE data makes no distinction between type 1 and type 2 diabetes because of changing patterns of the disease.
Year-on-year fluctuations may not indicate real changes and can be within the margins of sampling error. We comment only on the changes that are more likely to reflect a real change.
