According to a new study, people have differing abilities to release and react to insulin depending on ethnicity.

When the researchers looked more closely at the research subjects who were at risk of developing diabetes and the subjects who had already been diagnosed, the same pattern was observed. Their results were generally worse, however, as their insulin production or insulin sensitivity had begun to fail as part of the disease.
"The findings are consistent with what we see in clinical settings – East Asians are more sensitive to developing diabetes and they do so at a lower BMI. Because a lack of insulin is a condition for developing diabetes, it is not surprising that East Asians show lower insulin release and generally need to start insulin treatment at an earlier stage. The situation in Africa is still so complicated and heterogeneous that new studies are needed", says Professor Leif Groop from LUDC.
The researchers are not sure of the reasons for the physiological background to the changes, but suggest some possible explanations."Our findings and the fantastic developments in genetic research make us optimistic that we can continue to map the important differences that cause a failure in the production of insulin and reduced insulin sensitivity, so that we can emphasise personalised treatment in the future", concludes Damon Tojjar.
