B12 Vitamin Deficiency Signs and Symptoms
When diagnosing B deficiency one must be aware that hypo-thyroidism, hyper-thyroidism, coeliac/celiac disease and pyroluria manifest with similar symptoms, and are common co-existing conditions. The signs and symptoms below may not always signal a vitamin B12 deficiency. However, if you are experiencing some of these symptoms your doctor should rule out B deficiency as the cause. This will prevent a misdiagnosis
Not all of the signs must be present to raise a warning flag for B deficiency. However, if you are experiencing some of the symptoms listed below, you may want to have your vitamin B levels checked. Testing B12 levels with blood and a MMA test will help with a correct diagnosis.
Sometimes what appear to be normal test results, do not correctly diagnose a B deficiency. If your doctor cannot define a reason for your symptoms and they persist, try supplementing and see if after one or two months you begin to notice a decrease in your symptoms.
Folate and iron deficiency often accompany B12 deficiency. If your B12 is low then it is important to have folate and Ferritin (iron storage) levels checked. Often a B complex is prescribed when treating a B12 deficiency.
Pyroluria is a condition that causes persons to have chronic deficiencies of zinc and vitamin B6 Pyridoxine.
Celiac disease is a disorder resulting from an immune reaction to gluten, a protein found in wheat and related grains, and present in many foods. Celiac disease causes impaired absorption and digestion of nutrients through the small intestine. People with this condition are often deficient in B vitamins.
