If you live with diabetes, you may be aware that having the condition and its complications may put you at greater risk of developing anemia. But how are the two conditions related and what does this mean for you?

This article will investigate the relationship between diabetes and anemia, and what you should know if you have diabetes-related complications impacting your life.

According to the National Heart, Lung, and Blood Institute, Anemia is a condition in which the blood doesnt have enough healthy red blood cells to function properly. This leads to reduced oxygen flow to the bodys organs.

There are more than 3 million cases of anemia diagnosed in the United States every year, making this a very common condition.

You may experience the following symptoms:

Its important to note that some anemia symptoms are similar to symptoms of high blood sugar, including dizziness, lightheadedness, extreme fatigue, rapid heart rate, and headache.

Check your blood sugar often to make sure youre not confusing high blood sugar for suspected anemia. If your symptoms continue for a few days or weeks without high blood sugar numbers or ketones, call a healthcare professional to get checked for anemia.

Diabetes doesnt cause anemia and anemia doesnt cause diabetes. The two conditions are related, though.

Up to 25 percent of Americans with type 2 diabetes also have anemia. So its relatively common for people with diabetes, and especially diabetes-related complications, to also develop anemia.

However, if you have one condition or the other, you wont automatically develop the other condition.

As seen in this 2004 study, Anemia is a common complication of people with diabetes who develop chronic kidney disease because damaged or failing kidneys dont produce a hormone called erythropoietin (EPO), which signals to the bone marrow that the body needs more red blood cells to function.

Early stages of kidney disease (nephropathy) may be asymptomatic, but if youre diagnosed with anemia and you have diabetes, it might be a sign that your kidneys arent working properly.

People with diabetes are also more likely to have inflamed blood vessels. This prevents the bone marrow from even receiving the EPO signal to create more red blood cells to begin with. That makes anemia a more likely result.

Additionally, if you have existing anemia and are then diagnosed with diabetes, it may make you more likely to develop diabetes-related complications, such as retinopathy and neuropathy (eye and nerve damage).

A lack of healthy red blood cells can additionally worsen kidney, heart, and artery health, systems that are already taxed with a life lived with diabetes.

Certain diabetes medications can decrease your levels of the protein hemoglobin, which is needed to carry oxygen through the blood. These diabetes medications can increase your risk of developing anemia:

Since blood loss is also a significant contributor to the development of anemia, if you have diabetes and are on kidney dialysis, you may want to talk with your healthcare team about your increased risk of anemia as well.

Anemia can affect blood sugar levels in several ways.

One 2010 study found that anemia produced false high blood sugar levels on glucose meters, leading to dangerous hypoglycemia events after people overtreat that false high blood sugar.

As shown in a 2014 study, theres a direct link between anemia caused by iron deficiency and higher amounts of glucose in the blood. A 2017 review of several studies found that in people both with and without diabetes, iron-deficiency anemia was correlated with increased A1C numbers.

This resulted from more glucose molecules sticking to fewer red blood cells. After iron-replacement therapy, HbA1c levels in the studies participants decreased.

If you receive an anemia diagnosis and you live with diabetes, there are many excellent treatment options.

Treatment will depend on the underlying cause of the condition, but may include supplementation with iron and/or vitamin B.

If your anemia is caused by blood loss, a blood transfusion may be necessary. If your bodys blood production is reduced, medications to improve blood formation may be prescribed.

Diabetes and anemia are closely related, though neither directly causes the other condition.

Diabetes-related complications such as kidney disease or failure and inflamed blood vessels may contribute to anemia. Certain diabetes medications can also increase the likelihood of developing anemia. Anemia may also make diabetes management more challenging, with higher A1C results, false high blood sugars, and a potential risk of worsening organ health leading to future diabetes complications.

Still, anemia is very treatable with supplementation, dietary or medication changes.
