Vitamin B12 Defficiency (part 2)

Caution: Pernicious anemia is a serious medical condition. When fatigue, often the first symptom of PA, is present, a qualified healthcare practitioner should be consulted. Symptoms of PA can be caused by other conditions, none of which would respond to vitamin B12 supplementation. Moreover, if true vitamin B12 deficiency exists, the cause—lack of intrinsic factor, general malabsorption conditions, lack of stomach acidity, or dietary deficiency—must also be properly diagnosed by examination and blood tests before the appropriate treatment can be determined.

Symptoms

Symptoms of severe vitamin B12 deficiency (regardless of the cause) may include burning of the tongue, fatigue, weakness, loss of appetite, intermittent constipation and diarrhea, abdominal pain, weight loss, menstrual symptoms, psychological symptoms, and nervous system problems, such as numbness and tingling in the feet and hands. Most symptoms can occur before the deficiency is severe enough to cause anemia. Healthcare professionals have a series of laboratory tests that can determine B12 deficiency at earlier stages that are not accompanied by anemia.

Healthy Lifestyle Tips

Alcohol abuse can lead to gastritis and damage to the lining of the intestines, both of which can interfere with vitamin B12 absorption. If B12 deficiency is due to alcoholism, abstinence may prevent further impairment of B12 absorption.2
