What is the autoimmune disease associated with B12?

The primary autoimmune disease associated with Vitamin B12 deficiency is Pernicious Anemia, where the immune system attacks cells in the stomach (parietal cells) or the protein (intrinsic factor) needed to absorb B12, leading to anemia and potential neurological damage. People with pernicious anemia often have other autoimmune conditions like type 1 diabetes or thyroid issues, and it's more common in Northern Europeans, especially over 60.

What autoimmune disease affects B12?

Pernicious anemia is a relatively rare autoimmune disorder that causes diminishment in dietary vitamin B12 (cobalamin) absorption, resulting in B12 deficiency and subsequent megaloblastic anemia. It affects people of all ages worldwide, particularly those over 60.

Can B12 cause tingling in the lips?

If you have low levels of certain vitamins or nutrients, it could cause numbness in your lips. With low levels of vitamin B12, for example, you might have a burning sensation in your lips or mouth or cheilitis, which is inflamed or chapped lips. Iron deficiency anemia can also cause burning or numbness in your mouth.

What is the life expectancy of someone with pernicious anemia?

With proper, lifelong vitamin B12 treatment, people with pernicious anemia (PA) can live a normal life, as the condition is highly manageable; however, untreated PA leads to severe complications and can be fatal, while delayed treatment can cause permanent nerve damage, and there's a slightly increased risk of stomach cancer. The prognosis is excellent with consistent B12 replacement (shots or high-dose pills), but requires regular monitoring for potential complications like gastric malignancy.
 

Can B12 cause nausea?

Taking doses of vitamin B-12 might cause: Headache. Nausea. Diarrhea.

Autoimmunity causing B12 Deficiency

What are the worst symptoms of B12 deficiency?

The worst symptoms of B12 deficiency involve severe neurological damage, including difficulty walking, memory loss (potentially dementia), psychosis, hallucinations, paranoia, and severe numbness/tingling (peripheral neuropathy), alongside debilitating fatigue and anemia; these issues can become permanent if untreated, affecting nerves, cognitive function, and coordination.
 

What deficiency causes you to feel off balance?

Feeling off-balance or dizzy can stem from deficiencies in Vitamin B12, Vitamin D, Iron, Magnesium, Potassium, and Folate, which affect nerve function, muscle strength, oxygen supply, and inner ear balance, often leading to symptoms like staggering, weakness, or vertigo, though other conditions like anemia or inner ear issues also cause imbalance. A blood test is usually needed to confirm if a specific vitamin or mineral deficiency is the cause, so see a doctor if you experience persistent balance problems. 

What cancers are linked to B12 deficiency?

Particularly, individuals with lung, stomach, colon, oesophageal, and pancreatic cancers are more prone to experiencing a deficiency in vitamin B12. This article will discuss different types of cancers causing vitamin B12 deficiency, associated symptoms, and available treatment options.

How much sleep does an anemic person need?

In conclusion, while anemic individuals may experience sleep disturbances, there is no specific recommendation for sleep duration that differs from the general population. The focus should be on treating the underlying anemia to improve sleep quality rather than altering sleep duration.

How long after starting vitamin B12 will I feel better?

You may feel initial improvements in energy and mood within days to a couple of weeks, but significant relief, especially for nerve issues, can take several months, with B12 injections working faster than oral supplements. Expect minor boosts in energy in the first 24-72 hours, more noticeable increases in energy and better sleep by 1-2 weeks, and full recovery from severe deficiency taking 3-12 months for nerve healing. 

Can low B12 make your feet hurt?

You might want to investigate a B12 deficiency if you are experiencing foot pain or lower limb pain. Vitamin B12 is an essential nutrient, primarily found in animal products, that plays a key role in maintaining nerve function, producing red blood cells, and synthesizing DNA.

What is the Biermer disease?

Biermer's disease, also called acquired pernicious anemia, is a condition in which the body is unable to properly utilize vitamin B12. Because vitamin B12 is essential for the formation of red blood cells, this condition is primarily characterized by anemia (too few red blood cells).

What is the hardest autoimmune disease to diagnose?

There isn't one single "hardest" autoimmune disease to diagnose, but Vasculitis, Lupus (SLE), and Sjögren's Syndrome are frequently cited due to overlapping symptoms, slow progression, and varied presentations, making them "great imitators" that mimic many other conditions. Rare conditions like Idiopathic Inflammatory Myopathies (IIM), affecting muscles and organs, are also extremely challenging, with diagnoses sometimes taking years, notes Johnson & Johnson. 

What illnesses can cause vitamin B12 deficiency?

Causes of Vitamin B12 deficiency

• Malabsorption due to gastrectomy, gastric resection, crohn's disease, chronic alcoholism, coeliac disease, pancreatic failure and/or chronic alcoholism.
• Nutritional such as inadequate dietary intake of vitamin B12 (e.g., strict vegan diet) and malnutrition.

What kind of doctor treats pernicious anemia?

Primary care doctors—such as family doctors, internists, and pediatricians (doctors who treat children)—often diagnose and treat pernicious anemia. Other kinds of doctors also may be involved, including: A neurologist (nervous system specialist) A cardiologist (heart specialist)

What do you crave when your iron is low?

Iron deficiency can trigger unusual cravings, known as pica, for non-food items like ice (pagophagia), dirt (geophagia), or starch (amylophagia), and even smells like rubber or gasoline (desiderosmia). These cravings, especially for ice, often resolve with iron treatment and can indicate anemia, prompting a doctor's visit for diagnosis and management.
 

What drains iron from your body?

Iron is depleted by blood loss (heavy periods, surgery, bleeding ulcers), poor dietary intake (vegetarian/vegan diets without supplementation), impaired absorption (celiac disease, Crohn's, gastric bypass, certain medications), and increased demand (pregnancy, growth spurts, strenuous exercise). Certain drinks and foods like coffee, tea, and dairy can also hinder iron absorption, while conditions like cancer or chronic kidney disease further contribute to depletion.

What is a Stage 4 B12 deficiency?

Stage 4 B12 deficiency is the severe, clinical stage with significant neurological damage, anemia (megaloblastic), and cognitive decline, featuring symptoms like severe fatigue, numbness/tingling, balance issues, confusion, depression, and potential permanent nerve damage if untreated, requiring urgent medical intervention like B12 injections for recovery.
 

Can B12 deficiency cause blurry vision?

Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.

What are the injections for B12 deficiency?

Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, called hydroxocobalamin. At first, you'll have these injections every other day for 2 weeks or until your symptoms have started improving. Your GP or nurse will give the injections.

What do you crave when your B12 is low?

A B12 deficiency can cause unusual cravings, often for nutrient-rich, B12-containing foods like meat, fish, or eggs, but also potentially for sugar or even non-food items (pica), though this is rare, with symptoms like fatigue and anemia often accompanying the urges. While cravings can signal a shortage, they aren't definitive; doctors confirm B12 deficiency with tests, as cravings can stem from emotions or other nutritional gaps, not just B12. 

What disease starts with balance issues?

Losing your balance, often called dizziness or imbalance, can stem from various illnesses, most commonly inner ear issues like Benign Paroxysmal Positional Vertigo (BPPV), Ménière's disease, or Vestibular Neuronitis, which disrupt signals from the inner ear to the brain, causing spinning sensations (vertigo) or unsteadiness. Other causes involve nerve damage (neuropathy), certain medications, low blood pressure, or neurological conditions like Parkinson's. 

What is the surprising symptom that may signal vitamin deficiency?

Fatigue and weakness

Chronic fatigue is one of the most common and overlooked signs of vitamin deficiency. If you find yourself constantly tired, even after a good night's sleep, a lack of vitamin B12 might be to blame.
