A B12 deficiency can cause strange sensations and dizziness. The nervous system is “insulated” by myelin and is responsible for the transmission of signals throughout the body. When this lining is lacking, signals cannot travel from one part of the body to another. The result is that strange sensations can be felt in the arms, legs, and brain. These symptoms may also happen centrally in the spinal cord.
While there are several causes of vitamin B12 deficiency, a common symptom is dizziness. Vitamin B12 is important for the functioning of the nervous system, as it regulates blood pressure and increases the flow of blood to the brain. It is easy to test for a vitamin B12 deficiency using a simple blood test. Dietary sources of B12 include meat, dairy products, and fortified breakfast cereals.
Low levels of vitamin B12 may cause a number of symptoms including heart palpitations, pale skin, depression, and headaches. A person with a low level of B12 may also experience numbness, tingling, and pain in the mouth. In severe cases, vitamin B12 deficiency may require the administration of an injection or oral supplement. However, if you are unsure of the cause of your dizziness, consult your doctor immediately.
Anemia is a common symptom of vitamin B12 deficiency. Anemia, which has reduced red blood cells, causes the heart to beat faster than usual. A lack of red blood cells puts a strain on the heart, which in turn makes it work harder to pump blood and ensure adequate levels of oxygen reach the organs. Another symptom of vitamin B12 deficiency is shortness of breath. Without sufficient red blood cells, the body must pump blood at an extremely high rate to compensate for this lack of oxygen.
