Can People With Diabetes Give Blood
When it comes to giving blood, there are a number of conditions that can make you ineligible.
Unfortunately, people with diabetes wont, in most cases, be eligible to give blood. At least, not in the UK.
This is because NHS Blood and Transplant maintain a policy of refusing blood donations from anybody who may be placed at risk by giving blood. In many cases, this includes people with diabetes.
For Patients With Type 2 Diabetes
Interestingly, recent research has found that people with diabetes who donate blood regularly see short and longterm improvements in their health.
Heart attack, stroke and type II diabetes have all been shown to be less common in individuals that regularly donate blood, explains research from the King Abdullah International Medical Research Center .
For short-term health, the same study found that just one donation session temporarily improved insulin production and glucose tolerance.
The improvement was particularly evident three weeks after donation. By three months, most of the tested biomarkers returned to their pre-donation levels.
On the other hand, patients who donate blood shortly before an A1c test may have lower than accurate results, according to other research. Does this mean you shouldnt donate? No but it is something to keep in mind as you assess and manage your overall diabetes care.
Dont let diabetes stop you from donating blood if you are otherwise healthy and the country you live in welcomes donations from those with diabetes!
Monitor Your Blood Glucose Levels Post
Some Type 1 diabetics report slightly elevated blood glucose levels 3-5 days after donating. While your immediate levels wont spike or bottom out due to donating, it is possible that donating blood may cause your A1C or HbA1c to be falsely lowered. This is thought to be caused by blood loss and accelerated red blood cell turnover.
Monitor your blood sugar levels after donating and make sure to keep your body nourished by increasing your fluid intake and consuming more iron.
Unlike insulin diabetics use, blood cannot be made in the factory and only comes from volunteer donors. If your diabetes is well-controlled you can give whole blood every 56 days or donate plateletsevery 7 days.

Your A1c And Blood Sugar Levels Dont Have To Be Perfect
The ARC does not have any specific requirements when it comes to your A1c or blood sugar level at the time of donation. However, they do state on their website: Donors with diabetes who take any kind of insulin are eligible to donate as long their diabetes is well controlled.
Unfortunately, some other countries, including Canada and the United Kingdom, do not allow blood donations from anyone taking insulin.
The ARC has determined that high blood sugar levels in donated blood means the blood quality decreases in the days or weeks after donation. This means that managing your blood sugar levels as carefully as you can on the day you donate is very important. Near-normal blood sugar levelsbetween 70 to 140 mg/dLbefore and during blood donation make your donation more useful.
Only Two Types Of Diabetes Medications Can Exclude You From Donating
- Bovine insulin, derived from cows, poses a risk of carrying Mad Cow Disease. Even if its been years or decades since taking bovine insulin, you will not be eligible to donate.
- Warfarin is a blood thinner often used to treat high cholesterol, but it can also help lower blood sugar levels. It isnt safe or allowed to donate blood while taking a blood thinner.

But, according to a new study led by researchers at King Abdullah International Medical Research Center , just a single blood donation can temporarily improve a persons insulin production and glucose tolerance.
KAIMRC pathologist Anwar Borai led an international team that tested the levels of several key diabetes-related biomarkers in the blood of 42 healthy male donors.
Biomarkers, including those related to glycaemic status , insulin production and iron levels, were tested before donation and then one day, one week, three weeks and three months after giving blood.The results show that regular, repeated blood donation is not required to see a beneficial effect on the donors glucose tolerance. The glycaemic status of the donor can be mproved even after a single blood donation, Borai says.
The improvement was particularly evident three weeks after donation. By three months, most of the tested biomarkers returned to their pre-donation levels. Borai says improvements could continue if donors made healthy lifestyle changes after donation.
