Diabetes or elevated blood sugar levels managed with dietary changes or tablets is not an obstacle to donating blood. Insulin therapy is an obstacle to blood donation. The prerequisite is that no organ damage (such as macular changes or diabetic kidney disease) has been caused by diabetes and that there have been no episodes of low sugar (hypoglycaemia) or alarmingly high sugar levels (hyperglycaemia) in the last month, and that the medication has continued unchanged for a month.
