Anemia is a medical condition characterized by a deficiency in red blood cells or hemoglobin, crucial for carrying oxygen throughout the body.

This lack of oxygen can lead to various symptoms, including fatigue and weakness. But can anemia also cause anxiety? The answer is yes; the physical stress of low oxygen levels can indeed contribute to feelings of anxiety.

How anemia could lead to anxiety

Anemia, particularly when severe, affects not just physical health but can also have a significant impact on mental well-being.

Reduced oxygen supply

Anemia primarily reduces the blood’s oxygen-carrying capacity. With less oxygen available to body tissues, including the brain, individuals might experience symptoms like lightheadedness, dizziness, or a feeling of being short of breath.

These physical symptoms can trigger or worsen anxiety as the body responds to what it perceives as life-threatening situations.

Physical symptoms heightening stress

Common symptoms of anemia, such as fatigue, rapid heartbeat, and shortness of breath, can be unsettling and may lead to increased stress and worry.

For someone who might not understand that these are linked to anemia, these symptoms can feel inexplicable and frightening, fueling anxiety about their health and well-being.

Impact on cognitive function

Chronic anemia can affect cognitive functions, leading to difficulty concentrating and general mental fog.

These changes can create frustrations in daily life, especially if performing regular tasks becomes challenging. This ongoing struggle can build up stress and anxiety over time.

Psychological responses

The continual worry about the implications of having a chronic condition like anemia can also lead to anxiety. Concerns about the impact of anemia on one’s life and health, potential treatments, and the management of symptoms can contribute to an increased anxiety level.

Feedback loop between anemia and anxiety

There’s a potential feedback loop where anxiety caused by anemia can lead to behaviors that might worsen the anemia, such as poor eating habits or neglecting self-care. In turn, worsening anemia can intensify anxiety, creating a cycle that can be hard to break without intervention.

Understanding anemia — what causes it?

Anemia commonly results from low iron levels. However, several other factors also contribute to the prevalence of anemia. Here are the key causes that lead to reduced hemoglobin and healthy red blood cells:

Iron deficiency

The most common type of anemia, iron deficiency anemia, occurs when the body lacks enough iron to produce adequate hemoglobin.

Iron deficiency can result from inadequate dietary intake, increased iron needs during pregnancy, or blood loss through heavy periods or internal bleeding.

Vitamin deficiency

Anemia can also result from a lack of certain vitamins needed to produce red blood cells and hemoglobin. Vitamin B12 and folate are particularly important. Deficiencies may be due to poor diet, certain digestive disorders, or malabsorptive conditions that prevent the absorption of these nutrients from food.

Chronic diseases

Chronic conditions such as cancer, kidney disease, or autoimmune diseases can interfere with the production of red blood cells.

For example, chronic inflammation from these conditions can lead to anemia of chronic disease, which affects the body’s ability to use stored iron and produce new red blood cells effectively.

Genetic factors

Some types of anemia, such as sickle cell anemia and thalassemia, are inherited and result from genetic abnormalities that affect the shape or function of red blood cells. These conditions lead to premature destruction of red cells or faulty hemoglobin that cannot effectively carry oxygen.

Bone marrow and stem cell problems

Disorders affecting the bone marrow, the spongy tissue inside bones where blood cells are produced, can lead to anemia. This includes conditions like leukemia or myelofibrosis, which can crowd out healthy blood cells with abnormal cells or fibrous tissue.

Other causes

Other less common causes include hypothyroidism, advanced liver disease, and exposure to toxic chemicals or certain medications that can affect red blood cell production.

What are the symptoms of anemia?

Anemia can manifest through various symptoms, which may subtly influence your overall mental well-being, contributing to feelings similar to those experienced with anxiety. Here are the most common signs and symptoms of anemia:


Fatigue is one of the most common symptoms of anemia. This intense tiredness results from your body’s lack of oxygen, affecting your energy levels and possibly leading to feelings of unease or nervousness.


Generalized weakness, another hallmark of anemia, can hinder daily activities, potentially increasing stress and anxiety about routine tasks.

Pale or yellowish skin

The loss of the skin’s natural color, resulting from decreased hemoglobin in the blood, can also impact one’s psychological state by affecting self-image and social interactions.

Shortness of breath

If you find yourself frequently out of breath, even after light activities, it can provoke feelings of panic or anxiety, as it disrupts normal breathing patterns.

Dizziness or lightheadedness

These symptoms, caused by inadequate oxygen flow to the brain, can trigger disorientation and an acute anxiety response, especially in situations where balance and stability are crucial.

Heart palpitations

Irregular heartbeats not only cause physical discomfort but can also heighten anxiety due to the fear of a serious heart condition.

Cold hands and feet

This symptom, linked to poor circulation, might also exacerbate anxiety during social or professional handshakes, further affecting social confidence.


Frequent or severe headaches from anemia can be distressing and may cause worry about overall health, contributing to ongoing anxiety disorder.

Cognitive problems

Difficulties with concentration and focus due to anemia can lead to performance anxiety, especially in work or academic settings where cognitive demand is high.

Chest pain

Though less common, chest pain in anemic individuals can be particularly alarming, potentially triggering anxiety due to concerns over serious health issues.

Treating anxiety caused by anemia

When anxiety is a consequence of anemia, addressing the anemia itself is a primary step in treatment. Here are ways to manage and alleviate anxiety symptoms linked to anemia:

Correct the Anemia

  • Iron supplementation: If the anemia is due to iron deficiency, iron supplements can restore hemoglobin levels, improving oxygen transport and reducing symptoms like fatigue and weakness that may contribute to anxiety.
  • Vitamin B12 and folate supplementation: For anemia caused by deficiencies in B12 or folate, appropriate supplementation can help. These vitamins are crucial for nerve health and cognitive function, thereby potentially reducing anxiety.
  • Dietary adjustments: Increasing iron-rich foods (like leafy greens, beans, and red meat) and vitamins that aid in iron absorption (like vitamin C-rich fruits) can help combat anemia and its psychological effects.

Manage anxiety symptoms

  • Cognitive Behavioral Therapy (CBT): CBT can be highly effective in managing anxiety attacks by helping change negative thought patterns and behaviors associated with the anxiety caused by anemia.
  • Relaxation techniques: Practices such as meditation, yoga, and deep-breathing exercises can help alleviate physical and mental stress and reduce anxiety symptoms.
  • Regular exercise: Engaging in regular physical activity increases overall energy levels and improves mood by releasing endorphins, which can counteract the effects of anxiety.
  • Adequate sleep: Ensuring enough quality sleep can help regulate mood and improve cognitive function, vital in managing anxiety stemming from anemia.

Monitor and follow-up

  • Regular medical checkups: Regular follow-ups with a healthcare or mental health provider are crucial to monitor the progress in treating anemia and to adjust treatments as necessary. This also provides an opportunity to discuss any ongoing anxiety issues.
  • Psychological support: Consulting with a psychologist or psychiatrist may be recommended for ongoing management of anxiety, especially if it persists after anemia treatment.

Final thoughts

Anemia can greatly affect both your physical health and mental well-being, potentially making anxiety worse. Treating anemia can help ease these symptoms and improve your overall quality of life.
