Can Anemia Cause Depression?

If you’re feeling down and think you might be suffering from depression, it’s important to know that there are many possible causes. Anemia is one potential cause, and it’s important to be aware of the connection between the two.

Depression is a common condition that can be caused by a variety of factors, including anemia. Anemia is a condition in which the body does not have enough healthy red blood cells to carry oxygen to the tissues. This can lead to fatigue and other symptoms. In some cases, anemia can also cause problems with focus, memory, and concentration. It is not clear how anemia and depression are linked, but it is thought that anemia may play a role in the development of depression.

What is Anemia?

Anemia is a condition where there is a decrease in the number of red blood cells or hemoglobin in the blood. Anemia can cause fatigue, pale skin, and shortness of breath. In severe cases, it can cause heart problems and organ damage. Anemia can also cause depression.

Causes of Anemia

There are many different types of anemia, each with its own cause.

Iron deficiency anemia is the most common type of anemia. It can be caused by blood loss, such as from heavy menstrual periods or from gut bleeding (for example, due to ulcers, cancer, or hemorrhoids), or by not getting enough iron in your diet.

Vitamin deficiency anemias include those due to deficiencies of vitamin B12 or folic acid. Vitamin B12 deficiency anemia can be caused by not getting enough vitamin B12 in your diet (for example, vegans who don’t eat eggs or milk), by autoimmune conditions that destroy stomach cells (such as pernicious anemia), or by certain medications (such as antacids and metformin). Folic acid deficiency anemia can be caused by malnutrition, malabsorption disorders, celiac disease, pregnancy, and certain medications (such as antiepilepsy drugs).

Anemias can also be caused by bone marrow problems (such as leukemia), kidney problems (such as renal failure), or autoimmune diseases (such as lupus).

Symptoms of Anemia

The most common symptom of all types of anemia is fatigue. A person with anemia may feel tired all the time, even if they get enough sleep. They may also have trouble concentrating or remember, and feel dizzy or out of breath with exertion.

Other symptoms can include:
-pale skin
-fast or irregular heartbeat
-shortness of breath
-chest pain
-cold hands and feet
-dizziness or lightheadedness
-cravings forNon-Anemic foods high in iron, such as red meat

How does Anemia Cause Depression?

Anemia can cause depression due to a lack of nutrients and oxygen in the brain. When there is a lack of these things, it can cause the brain to function less effectively. This can result in a person feeling tired, irritable, and sad. If you are dealing with anemia, it is important to talk to your doctor about how it is affecting your mood.

Brain Changes

Anemia can cause depression by altering brain function. A 2009 study published in “Psychiatry Research: Neuroimaging” looked at the relationship between anemia and brain function using MRI. Researchers found that anemia was associated with changes in the frontal and temporal areas of the brain. These are the areas of the brain that control mood, emotions and behavior.

Hormone Changes

There are many ways that anemia can cause depression. One of the most common is through hormonal changes. When you have anemia, your body does not produce enough red blood cells. Red blood cells play a vital role in carrying oxygen to your tissues and organs. Without enough of them, your body does not function properly. This can lead to a decrease in the production of hormones, including serotonin. Serotonin is a neurotransmitter that plays a role in mood regulation. Low levels of serotonin are linked to depression.


As you can see, anemia can cause depression. If you think you may be suffering from anemia, it is important to see a doctor to get a proper diagnosis. Treatment for anemia can vary depending on the cause, but may include taking iron supplements or taking medication to increase red blood cell production.
