What To Know About Diabetes And Donating Blood

This is important due to our current blood shortage.

Medical News Today

Diabetes can make it difficult for a person to control their blood sugar levels, which are often too high. People with this condition may need to use external sources of insulin to correct these levels. However, people can donate blood if they have diabetes.

Every 2 seconds, someone in the United States needs blood, but supplies are low due to COVID-19.

Although donating blood is possible, people with diabetes will need to consider several important things first, and they will need to monitor their recovery closely.

In this article, we look at how diabetes can affect blood donations and explain the procedure of donating blood.

Can a person with Diabetes donate blood?

According to the Centers for Disease Control and Prevention , people with diabetes tend to have higher blood sugar levels than normal and often use insulin injections or oral diabetes medications to help balance them.

The National Institutes of Health say that having diabetes should not affect a persons ability to donate blood as long as they are feeling well, and the diabetes is under control.

In some cases, blood donation may actually improve markers of diabetes. A smaller study featuring in Clinical Biochemistry found that males who donated blood had improved glucose tolerance after 3 weeks.

People with diabetes will still need to meet other criteria for donating blood, such as:

Each individual can only donate blood every 56 days.

Unanswered Questions And Future Research

Most blood donors didnt reach their predonation HbA1c concentration at the end of the study. As the study used a follow-up period of 8 weeks, it is not possible to give an advice on when the HbA1c has returned to its predonation concentration and when it can be reliably used by the general practitioner or internist for treatment evaluation or diagnosis of type 2 diabetes. Blood donors are eligible to donate again 8 weeks after the previous donation, with a maximum of 5 times a year for males and 3 times for females. Theoretically this could lead to a sequential reduction of HbA1c resulting in a new steady state which will be lower than the true HbA1c concentration. It should be stressed that reduction of HbA1c due to whole blood donation does not reflect a general decrease in advanced glycation end products and therefore is not associated with a decreased risk of developing complications associated with type 2 diabetes.

Strategies Proven To Lower Blood Sugar

Reported Health Benefits Of Giving Blood

The health benefits of blood donation include lowering your heart rate, your blood pressure, and weight. Some researchers have also found that donating your blood regularly can lower your cholesterol and triglyceride levels. It may seem to be an effective way to lower your lipid levels. After all, when you donate your blood, you are donating the lipids in your blood, too, right?

Should You Stop Your Blood Pressure Medicine On The Day Of Donation

You will need to ask your own doctor whether or not you should take your antihypertensive medications on the day of your donation.

I usually advise people to book an early appointment, and to miss their early morning blood pressure medication. This helps to ensure their donation contains very little of the drug they are taking, and also helps to reduce the chance of developing hypotension and feeling faint or dizzy after donating.

Its then a good idea to monitor your blood pressure throughout the rest of the day and to take your medication if your blood pressure rises above your target readings.

Your own doctor may disagree, based on your past medical history and how well your blood pressure is generally controlled, so please ask their advice first.

And always mention any medication you are taking to the staff at session before you donate.

If your blood pressure is raised, self-monitoring is important to maintain good control.

A Happier Longer Life

One blood donation can save up to three lives, according to Dr. DeSimone. People usually donate because it feels good to help others, and altruism and volunteering have been linked to positive health outcomes, including a lower risk for depression and greater longevity.

Giving blood is a way to engage in the immediate community and help people around you, Dr. Vossoughi adds. People who do these types of things and engage in their community in this way tend to have better health and longer lives.

It is also a way to feel that you have positively helped during the COVID-19 crisis. Donating blood is safe if you have had the COVID-19 vaccine. It is also safe if you have had COVID-19, though you must be symptom-free for two weeks and have not had a positive diagnostic test for COVID-19 in the last 14 days, Dr. DeSimone says. If you have any COVID-19 symptoms like a fever or cough, do not give blood. Donating blood is safe as donors are socially-distanced and required to wear a face mask covering their nose and mouth, regardless of vaccination status.

Creating moments of kindness during a time of need does wonders for your mental health and feeling of well-being, Dr. DeSimone says.

Zinc For The Prevention Of Diabetes

Because zinc deficiency is associated with prediabetes and type 2 diabetes, researchers want to know, can zinc help prevent the onset of diabetes? Although more studies are needed to know for sure, preliminary research suggests that it can . In one study following 82,297 women across 24 years, those who had higher zinc intakes had a lower risk of developing type 2 diabetes.

When To Avoid Exercise

People with blood sugar levels above 240 mg/dL should check their urine for ketones before engaging in physical activity. If ketones are present, do not exercise. Ketones are the result of stored fat being broken down for energy. Your liver starts breaking down fat when theres not enough insulin in your bloodstream to absorb blood sugar into cells. When too many ketones are quickly produced, they can cause DKA. In this state, ketones may actually make your blood sugar level go even higher and you may need intravenous fluids to rebalance.
