DONATING BLOOD AS A DIABETIC? HERE ARE SOME THINGS TO KEEP IN MIND

One of the most common questions asked by diabetic patients around World Blood Donor Day is: "Can I donate blood?" So many myths and misconceptions deter people from the noble cause of blood donation, including whether or not diabetics can donate blood.

To clear the air around diabetes and blood donation, we reached out to Dr Mahesh Chavan - Consultant, Endocrinologist and Diabetologist, Apollo Hospitals, Navi Mumbai, who highlighted that diabetes, by itself, does not disqualify someone from donating.

However, there are a few conditions that must be considered.

Check Blood Sugar Before Donation

The first thing to be done is to check blood sugar levels before heading to a donation centre. Ideally, they should be within your normal target range. If you're running low or unusually high that morning, postpone the donation. It's not worth the risk of a hypoglycaemic episode while you're on the donor chair.

Inform The Staff About Your Blood Glucose

Insulin use is not automatically a barrier. However, it is your responsibility to tell the staff at the donation centre about your medications, insulin regimen, and recent glucose readings. They need that information to make the right call for both you and the recipient.

Maintain Hydration

A study published in the Global Journal of Transfusion Medicine shows that hydration helps in preventing vasovagal reactions after blood donation. Therefore, drink enough water before and after blood donation. It is advisable to eat a healthy snack after the donation, but ensure that what you eat does not give you a sugar spike. Generally, people are given juice to drink after donating blood. You can opt for citrus juice as it doesn’t raise blood glucose.

Check Your Blood Sugar After Donation

Monitor your blood sugar for a few hours afterwards, especially if you're prone to fluctuations. It is also advisable to avoid strenuous physical activity for the remainder of the day to stabilise glucose levels.

Do Not Go Alone

One thing Dr Chavan cautions against is going for blood donation alone. Take someone with you, at least if you are donating blood for the first time. If you feel dizzy or your blood sugar levels drop unexpectedly, you should have support.

Consult Your Doctor Before Donation

While diabetes is a lifestyle disease, the condition isn’t the same with everyone. If you have any active diabetes-related complications, such as diabetic neuropathy, nephropathy, or recent hospitalisations, get clearance from your treating physician before you donate.

Final Word

Donating blood is a generous act, but your health comes first. When in doubt, a discussion with your treating physician before donation can help ensure that the experience is both safe and comfortable.
