Bear in mind you’ll need to share with the blood donation center that you have diabetes and whether or not you’re currently taking medication for diabetes. In addition, you may be asked a few additional questions about your health history. </p><p>Here are the steps to take before donating blood when you have diabetes:</p><ul><li>Load up on iron-rich foods, including red meat, fish, poultry, beans, spinach, iron-fortified cereals, or raisins in the days (or weeks) leading up to your appointment.</li><li>Continue maintaining a diabetes-friendly diet to help with blood sugar levels (i.e., limit fried foods, desserts, and soft drinks)</li><li>Before your appointment, consume an extra 16 ounces of water or other non-alcoholic and non-caffeinated drink.</li><li>Sleep well the night before (i.e., aim for eight hours). </li><li>Make sure you have a list of medications and two pieces of personal identification, like a driver’s license.</li></ul><h2>After </h2><p>It's important to regularly check your blood sugar after donating blood.

One 2017 study published suggested donating blood lowers A1C levels in people with type 2 diabetes and people living without diabetes.</p><p>The researchers concluded that after donating blood, people with type 2 diabetes might be at risk of falsely lowered levels of HbA1c (A1c). This may lead to inaccurate interpretations of blood sugar control from their healthcare provider or diabetes specialist. </p><p>To prevent misreadings or to ensure your healthcare provider has all the necessary context to understand your readings, be sure to mention to your healthcare providers when you plan to and if you’ve recently donated blood (i.e., within the last few months).</p><h2>Summary </h2><p>People with type 1 or type 2 diabetes can donate blood as long as their diabetes is under control. Taking diabetes medications doesn't usually interfere with a person’s blood donation eligibility. Donating blood when you have diabetes requires continuing to take good care of yourself and following general requirements for preparing before and after donating blood. Remember that donating blood has been shown to lower A1c levels, so always let your healthcare provider know the last time you donated blood. </p><h2>A Word From Verywell </h2><p>If you’ve been having difficulty managing your diabetes, you’ll need to focus on this first. So while it’s admirable to want to give back to the community today, you may want to use the goal of donating blood to help you assess what’s missing from your current diabetes care plan. Speaking with your healthcare provider about the next steps is a great place to start.</p><p>Frequently Asked Questions</p><ul><li>According to one study, blood donation may temporarily benefit people with diabetes.
