Having an insulin treatment can be a source of exclusion to donate blood although the last word is the transfusion centers.
Leaving aside that they accept or not someone's blood with diabetes I have never donated blood since I have diabetes, I am very sorry but it is hard for meComplication (small but complication) for someone with diabetes and insulin treatment.
Regarding the donation of organs:
Every transplant has an autoimmune problem in the background (unless it is a self -transplant where the recipient and the donor are the same person, but that is a very particular case ...) problem that makes the receiver need medication to be immunosuppressedrest of your life (if Immunodepressants stop taking the organs or transplanted organs end up being rejected) on the other hand a person who has type 1 diabetes has an autoimmune disease, the fact of using organs of a person who has type 1 diabetesIt makes the autoimmune problem even greater (autoimmune problem of every transplant + particular autoimmune problem) the last word is the transplant team but the fact of having diabetes I do not think to help to give green light, quite the opposite.

Clinical evaluation of the organ donor.
The selection of a corpse donor is a complex and multidisciplinary procedure that involves intensivist doctors, transplant coordinators, immunologists, pathologists, nephrologists and many other specialists involved or not in transplant programs.
In general, all those bodies of brain death by cranioesephalic trauma, stroke, cerebral anoxia or non -metastatizing brain tumors are considered donors.
The donor evaluation has two objectives:
Discard any donor transmissible disease
· Make a functional and morphological assessment of the organs to be transplanted.

II.B.Validation criteria depending on the organ to transplant
1.General criteria of exclusion .
1.1.Coma of unknown cause.
1.2.Transmissible infectious pathology: AC HIV+, sepsis with hemodynamic impact.
1.3.Risk groups: prostitution, prison, drug addiction I.V.
1.4.Cancer (except skin and some primitive CNS or definitely cured)
1.5.Hematological diseases of unknown cause
1.6.Neurological diseases of unknown or degenerative cause.
1.7.Collagenosis
1.8.Generalized arteriosclerosis
1.9.Arterial hypertension or diabetes with serious visceral impact
1.10.Anencephals

That said ... the last word is the transplant team but having diabetes I do not think it helps to give a green light to be donor of organs.
I would personally worry more than having diabetes was a reason for exclusion to be a receiver ...
