Vitamin B12 is an essential vitamin that supports vital functions in the body. It plays a key role in many important processes such as red blood cell production, nerve system health, and DNA synthesis. However, B12 deficiency can lead to serious health problems over time. One of these is heart palpitations (tachycardia), which are rapid and irregular heartbeats.
B12 deficiency may initially present with mild symptoms, but over time it can cause more serious health issues. If left untreated, it can lead to complications such as nerve system damage, memory problems, and heart disorders. Therefore, early diagnosis and appropriate treatment are crucial.
B12 deficiency has various effects on the body, one of which involves heart health. So, can B12 deficiency cause heart palpitations? In this article, we will explore the effects of B12 deficiency on heart health, its causes, and potential solutions in detail.
A Real Example: B12 Deficiency and Heart Palpitations
Ayşe, who experienced frequent dizziness, fatigue, and heart palpitations in recent months, consulted a doctor. Blood tests revealed a severe B12 deficiency. Thanks to the B12 supplements and dietary changes recommended by her doctor, her symptoms improved quickly. Cases like this highlight how important B12 deficiency is.
Does B12 Deficiency Cause Heart Palpitations?
Yes, B12 deficiency can cause heart palpitations. There are several reasons for this:
Anemia (Low Red Blood Cells) and Heart Palpitations
Vitamin B12 plays a crucial role in red blood cell production. When deficient, the body cannot produce enough healthy red blood cells, leading to a condition called megaloblastic anemia.
Due to anemia, oxygen cannot be carried efficiently to the tissues, and the heart has to work faster to compensate for the oxygen deficiency. This can lead to heart palpitations, dizziness, and shortness of breath.

Effects on the Nervous System
Vitamin B12 is essential for the protection and proper functioning of nerve cells. B12 deficiency can cause nerve damage, leading to symptoms such as stress, anxiety, and panic attacks. Anxiety and stress can directly increase heart rate, causing palpitations. Additionally, imbalances in blood pressure due to nervous system damage can negatively affect the heart’s rhythm.
🧠💡
Low Blood Pressure (Hypotension) and Pulse Changes
People with B12 deficiency may experience low blood pressure. Low blood pressure can lead to symptoms such as fatigue, dizziness, fainting, and cold hands and feet. In daily life, this can result in issues like dizziness when standing up quickly, difficulty standing for long periods, and rapid exhaustion during physical activities. Focus problems and mental fog may also be observed. Low blood pressure can make the heart beat faster to pump sufficient blood to the body, which can lead to heart palpitations. This can also manifest as pulse irregularities and dizziness.
