Can you donate blood with uncontrolled diabetes type 2?

If you take insulin, you are not eligible to donate. The rationale is that donating blood could interrupt your blood glucose control, and potentially lead to a hypoglycemic reaction in the clinic or on the way home.

If you manage your Diabetes with lifestyle or diabetes pills, you may be eligible, depending on your overall health. Many people who have type 2 diabetes have blood pressure and heart problems, which would prevent them from donating.
