We often hear about the importance of vitamins for our health, but one in particular plays a crucial role and, when deficient, can cause subtle symptoms that are difficult to connect with each other: Vitamin B12. Also known as cobalaminThis water-soluble vitamin is essential for the proper functioning of our body, yet its deficiency is more widespread than you might think.
In this article, we'll explore the vital functions of vitamin B12, the symptoms of a deficiency, and how the HUB Outpatient Clinic can help you monitor your nutritional status.
What is vitamin B12 used for: its vital functions
Vitamin B12 is not a simple molecule, but an essential cofactor in numerous biochemical processes in our body. Its main functions are:
- nervous system healthB12 is essential for the production of myelin, a protective sheath that covers nerves and ensures the proper transmission of nerve impulses. A deficiency can lead to neurological damage and memory problems.
- formation of red blood cells: together with vitamin B9 (folic acid), B12 is essential for DNA synthesis and the maturation of red blood cells in the bone marrow
- energy metabolism: plays a key role in converting food into usable energy, helping to maintain high levels of vitality and counteract feelings of tiredness.
Since our body is not able to produce it on its own, we have to take it through food, mainly from animal sources.
What happens if you're deficient in vitamin B12: symptoms to recognize
Vitamin B12 deficiency can manifest itself insidiously, and symptoms can be confused with those of other conditions, leading to a delay in diagnosis. Common signs include:
- persistent tiredness and weakness: one of the most frequent symptoms, due to anemia (lack of red blood cells)
- tingling, numbness, or burning: The alteration of the nervous system can cause tingling sensations in the hands and feet, or a feeling of numbness
- memory and concentration difficulties: deficiency can affect cognitive function, leading to confusion, difficulty concentrating and, in more severe cases, memory impairment
- megaloblastic anemia: a form of anemia in which red blood cells are larger and fewer in number than normal, making them inefficient at carrying oxygen
- glossitis: the tongue may appear smooth, swollen and painful
- irritability and mood swings: deficiency can also affect psychological well-being.
The main causes of deficiency
There are two main causes of B12 deficiency: insufficient dietary intake or an absorption problem.
DietVitamin B12 is found almost exclusively in foods of animal origin (meat, fish, eggs, dairy products). For this reason, people who follow a vegan or vegetarian diet In the long term, they are particularly at risk of deficiency and should monitor their levels and take specific supplements.
MalabsorptionThis is the most common cause of deficiency in Western countries. Even if the diet is rich in B12, the body is unable to absorb it due to:
- Pernicious anemia: an autoimmune disease in which the body does not produce intrinsic factor, a protein needed for the absorption of B12 in the intestine
- gastrointestinal diseases: diseases such as Crohn's disease, celiac disease, or the presence of ulcers and atrophic gastritis
- surgeries: removal of part of the stomach or intestine (e.g. bariatric surgery)
- old age: with aging, the production of gastric acid and intrinsic factor tends to decrease
- use of certain medications: drugs for diabetes (metformin) or for reducing gastric acidity (proton pump inhibitors) may interfere with absorption.
How to diagnose and manage a deficiency
The diagnosis of vitamin B12 deficiency is simple and is based on a blood test. Evaluating B12 levels, combined with other parameters such as methylmalonic acid, can provide a clear picture of the situation.
Once the deficiency is identified, management depends on the cause:
- deficiency due to insufficient intake: it is resolved by taking oral supplements, often in high doses to allow passive absorption
- malabsorption deficiency: usually requires periodic intramuscular injections, in order to bypass the problem of absorption at intestinal level.
Is critical avoid self-diagnosis and self-treatment with DIY supplements. Medical advice is essential to identify the cause of the deficiency and establish the correct treatment.
