Can Diabetics Donate Blood? Addressing the Stigma

By: Rhea Gupta

Every 60 seconds, someone in Canada requires blood, highlighting the constant need for blood donations across Canada (Canadian Blood Services, n.d.). Blood donation is vital for saving lives and supporting healthcare systems in Canada. However, there is a significant stigma around whether people with diabetes, especially those with Type 1 Diabetes (T1D), can donate. While there were past concerns that individuals with diabetes faced barriers to donating, recent changes in eligibility guidelines, effective since 2021, now allow individuals with both T1D and Type 2 Diabetes (T2D) to donate blood under specific conditions (Canadian Blood Services, n.d.). This challenges the misconception that diabetics are automatically excluded from eligibility criteria (Diabetes Canada, 2021).

Why Does This Stigma Exist? 

There is a common misconception that people with diabetes should not be eligible for donating blood, especially those with T1D due to the autoimmune deficiency of producing insulin. This stigma may stem from societal concerns about unstable blood sugar levels, insulin use, and other potential complications such as hypoglycemia or hyperglycemia. As in the past, those with T1D were previously ineligible to donate, this further reinforced the concept of all forms of diabetes to be ineligible. However, with modifications in eligibility criteria based on current research, our goal is to demystify this misconception.  

Blood Eligibility Criteria in Canada 

The criteria for blood donation in Canada for diabetics, as outlined by Canadian Blood Services and Diabetes Canada, are as follows (Canadian Blood Services, n.d; Diabetes Canada, 2021): 

1. General eligibility 

   • At least 17 years of age and meet height/weight requirements 

   • No recent vaccinations 

   • Have NOT experienced acute diabetes event in the past 3 months

     1. No occurrences of hypoglycemia or hyperglycemia that required interventional treatments

2. For those managing blood sugar with diet and/or medications other than insulin 

   • Well-managed blood sugar levels 

3. For those managing diabetes with insulin

   • No foot ulcers that required medical treatment 

   • No symptoms of dizziness/lightheadedness while standing up 

   • For T1D – one must eat within 2 hours before donating 

Preparation and Benefits

Donating blood can help individuals with diabetes feel empowered and give back to their community. With Canada’s demand for blood supplies, raising awareness about these eligibility guidelines not only benefits diabetics who wish to donate but also ensures that blood donations are safe for the recipients who rely on them. With the potential of donation becoming a part of their healthy and active lifestyles, it can also reinforce the importance of diabetes management. There are some things individuals with diabetes can do to prepare before donating blood, such as monitoring blood glucose levels, staying hydrated, and eating a healthy meal before donating. Most importantly, it’s crucial to listen to your body, especially if you feel unwell, have uncontrolled blood sugar levels, or have experienced recent episodes of hyperglycemia or hypoglycemia. 

Conclusion

The changes in Canadian Blood Services' guidelines have helped break down the stigma around diabetes and blood donation, ensuring that people with Type 1 and Type 2 diabetes who manage their condition well can participate. By donating blood, diabetics can not only contribute to the community but also be a part of changing the narrative around the condition. With proper preparation, blood donation is a safe and empowering way to help save lives. Therefore, myths related to diabetes and insulin use can be dispelled by understanding that the key factor for eligibility is diabetes management.
