What is Vitamin B12 Deficiency?
Vitamin B12 deficiency is a condition in which the body does not possess sufficient Vitamin B12. It is generally caused by inadequate dietary intake, yet can also be a result of conditions affecting the stomach or intestines that impede the absorption of the vitamin. Common symptoms of Vitamin B12 deficiency include fatigue, lethargy, yellow skin, and a sore tongue. Additionally, neurologic deficits such as neuropathy and ataxia may be present, as well as megaloblastic anemia.
If left untreated, some of the issues caused by Vitamin B12 deficiency can be irreversible. Consequently, it is essential to diagnose and treat Vitamin B12 deficiency in a timely manner, as the symptoms may improve with treatment.
Risk factors for developing Vitamin B12 deficiency include long-term use of proton pump inhibitors, vegetarian diet, and other conditions that interfere with the body's ability to absorb the vitamin.
What are the Symptoms of Vitamin B12 Deficiency?
The indications of Vitamin B12 deficiency vary from person to person, but some of the most commonly reported symptoms include fatigue, weakness, numbness or tingling, difficulty walking, mood changes, memory loss, disorientation, and dementia. Vitamin B12 deficiency can also cause megaloblastic anemia, which is a condition caused by impaired DNA synthesis, resulting in symptoms such as pallor and fatigue. Glossitis, an inflammation of the tongue characterized by redness and pain, is also often associated with Vitamin B12 deficiency.
For infants, Vitamin B12 deficiency can lead to failure to thrive, motor skill difficulties, delays in achieving developmental objectives, and anemia. Vitamin B12 deficiency can also cause neurological issues that affect the nervous system, such as headaches. Gastrointestinal symptoms such as diarrhea, nausea, constipation, bloating, and gas may be experienced.
What Causes Vitamin B12 Deficiency?
Pernicious anemia is an autoimmune condition that is the primary cause of vitamin B12 deficiency. This condition arises when antibodies attack the stomach lining cells, preventing them from producing intrinsic factor, which is essential for the absorption of vitamin B12.
Vitamin B12 deficiency can be caused by conditions or surgeries that affect the stomach or intestines, certain medications or inadequate dietary intake. Other factors like age, veganism, alcohol abuse and eating disorders also contribute to Vitamin B12 deficiency. Individuals who adhere to a vegan diet, as well as those aged over 75 or over 65, are more likely to develop a vitamin B12 deficiency.
Pernicious Anemia
Pernicious anemia is an autoimmune disorder. Antibodies to intrinsic factors are developed within the body when a person has this condition. Without intrinsic factor, the body is unable to absorb vitamin B12, resulting in vitamin B12 deficiency.
The condition is more likely to occur in women of approximately 60 years of age, individuals who have a family history of the condition, and those who have another autoimmune disorder.
Diagnosis of the condition is done through a blood test to measure levels of vitamin B12 and intrinsic factor antibodies. Those with pernicious anemia are at an increased risk of developing stomach cancer.
Conditions Affecting the Stomach and Intestines
Conditions affecting the stomach and intestines can impede the body's ability to absorb nutrients effectively. This includes Crohn's disease, an inflammatory bowel disease that affects any portion of the digestive tract. Crohn's disease can cause surgical resection, which impedes the absorption of B12 and can lead to a deficiency.
Celiac disease, an autoimmune disorder that causes inflammation of the small intestine when gluten is ingested, can also lead to a vitamin B12 deficiency. Gastric bypass surgery, a weight loss procedure that involves the formation of a small stomach pouch and redirection of the small intestine, may also result in a B12 deficiency due to the bypassing of the site of intrinsic factor production.
Medications such as proton pump inhibitors (PPIs) and H2 blockers are employed to treat stomach conditions, however, they can reduce the amount of acid in the stomach, which is necessary for the absorption of vitamin B12.
Malabsorption, the inability of the body to absorb nutrients, can also lead to a vitamin B12 deficiency.
Medications
Metformin neomycin chloramphenicol, colchicine, and certain anticonvulsant drugs have been known to cause a vitamin B12 deficiency. Proton pump inhibitors (PPIs) can impede the assimilation of Vitamin B12, and those taking medications that may result in a vitamin B12 deficiency should consult their healthcare practitioner regarding any apprehensions they may have regarding vitamin B12 deficiency.
It is important to note that folate deficiency and vitamin B12 deficiency are distinct from each other, with folate deficiency being a deficiency of the nutrient commonly referred to as folic acid or vitamin B9, while vitamin B12 deficiency is a lack of the nutrient also known as cobalamin.
Inadequate Dietary Intake
It is considered to be an inadequate dietary intake when there is not sufficient consumption of a specific nutrient, such as vitamin B12. Animal-based foods such as meat, fish, and dairy products are known to have a substantial amount of vitamin B12. A vegan diet may result in an inadequate dietary intake of vitamin B12 due to the exclusion of meat, fish, and dairy products, which are the primary sources of vitamin B12.
Folate deficiency can be attributed to inadequate dietary intake of folate, which is distinct from vitamin B12. Though, megaloblastic anemia, which can be caused by a deficiency in either vitamin B12 or folate, may present with similar symptoms. A vegan diet should also be carefully monitored to ensure that the individual is not at risk of folate deficiency anaemia. Individuals who adhere to a restrictive diet or who suffer from gastric bypass surgery, celiac disease, or Crohn's disease are also at risk for a vitamin B12 deficiency.
It is important to note that a vitamin B12 deficiency can also be caused by drinking excessive amounts of alcohol, which can impair DNA synthesis and disrupt the body's ability to produce healthy red blood cells that can properly carry oxygen. A vitamin B12 deficiency can also be caused by impaired absorption of the vitamin due to a lack of intrinsic factor, as seen in pernicious anemia.
Therefore, it is essential to consult with a healthcare practitioner regularly to identify any symptoms related to a poor diet or a vitamin B12 deficiency. The National Institutes of Health (NIH) recommend dietary supplements for individuals who are at a high risk of developing a vitamin B12 deficiency.
Diagnosis of Vitamin B12 Deficiency
Physicians diagnose vitamin B12 deficiency by obtaining a patient's medical history and conducting a physical examination. A complete blood count (CBC) with a peripheral smear and serum B12 and folate levels are blood tests that are utilized in order to diagnose vitamin B12 deficiency.
It is generally accepted that B12 levels above 300 pg/mL are considered normal, levels of 200–300 pg/mL are considered borderline, and levels below 200 pg/mL are considered deficient. A person is considered to be deficient in vitamin B12 if their blood test results show a level of less than 150 per mL. This deficiency can lead to a variety of signs and symptoms.
It is imperative to rule out folate deficiency before testing for vitamin B12 deficiency, as folate deficiency can present with similar symptoms and may mask the presence of vitamin B12 deficiency. To ascertain the cause of vitamin B12 deficiency and determine the appropriate course of treatment, additional tests such as blood tests for pernicious anemia and other conditions may be necessary.
