Can You Donate Blood if You Have Diabetes?

There isn’t a clear answer between diabetes and blood donation since it relies on many factors. In short, it’s all about sugar levels and the type of insulin you have been using. It does not matter which type of diabetes you have as the eligibility criteria depend on your diabetes management and your medications.



Prediabetes is a condition where the sugar levels in the body are above the normal range, yet not so high as to be diagnosed as diabetes. A person with prediabetes can donate blood if he/she does are not prone to any heart conditions.


Type-1 diabetics are completely deferred from donating blood as they are dependant on insulin to control blood sugar levels. In the case of blood loss from the body, the patients are prone to hypoglycemia (a condition where the sugar levels dangerously go low).


If you are maintaining your sugar levels with the help of a proper diet and strenuous physical activity, then you are good to donate blood. Diabetes and blood donation can go hand in hand if you are controlling your sugar levels, through lifestyle changes.

Conditions That Stop You from Donating Blood

There are a few conditions that can permanently defer a diabetic from donating blood. The following are the most common:

  • Ulcers, diabetic neuropathy, or any numbness-related condition
  • Hypoglycemia (when blood sugar levels are below 70 mg/dL or below)
  • Diabetics who have had a pancreatic tissue transplant
  • People with diabetes having kidney problems
  • Diabetic retinopathy, a complication that damages the blood vessels in the tissues of the eyes
  • Any heart complications
