​Vitamin B12 deficiency signs that are mostly ignored​

Vitamin B12 plays an important role in a variety of bodily functions, including red blood cell formation, neurological health, and DNA synthesis. B12 cannot be produced by the body on its own, so it must be obtained from food or supplements. Ignoring the signs of B12 deficiency can lead to serious health problems over time. Here are some signs of vitamin B12 deficiency and identify which ones are essential.

Vitamin B12 is essential for maintaining healthy nerve cells. Deficiency can cause neurological symptoms such as numbness, tingling, and difficulty walking. Neurological symptoms develop gradually and can be mistaken for other diseases, delaying diagnosis and treatment.

Vitamin B12 deficiency can affect cognitive function and cause memory loss, difficulty concentrating, and mood changes. Changes in cognitive function can be caused by aging or stress, and may not be immediately linked to nutritional deficiencies.

Anemia caused by vitamin B12 deficiency may cause the skin to appear pale or yellowish. Changes in skin tone can be due to other factors, and individuals may not recognize it as a sign of nutritional deficiency.

Vitamin B12 deficiency can affect coordination and balance, leading to difficulty walking and an increased risk of falls. Problems with walking can be related to aging or other neurological conditions, which can distract from possible vitamin B12 deficiency.

People who follow a strict vegetarian or vegan diet may not get enough vitamin B12 from food sources due to limited plant-based options. Conditions that affect the stomach and intestines, such as atrophic gastritis, celiac disease, Crohn's disease, and pernicious anemia, can interfere with the absorption of vitamin B12. As we age, the production of stomach acid and intrinsic factor decreases, which can affect the absorption of vitamin B12. Certain drugs, such as proton pump inhibitors (PPIs), H2 blockers, and metformin, can reduce B12 absorption. Surgical procedures involving the stomach and intestines, such as weight loss surgery, can limit B12 absorption. This bacterial infection of the stomach can affect the lining of the stomach and reduce the absorption of vitamin B12.

A balanced diet includes sources of vitamin B12 such as meat, fish, dairy products, and eggs. If you follow a vegetarian or vegan diet, consider a vitamin B12 supplement. Vitamin B12 supplements are available in a variety of forms, including oral tablets, sublingual tablets, and injections. Consult your health care professional to determine the appropriate dosage and supplement form.

​Which food contains the most vitamin B12?​

Vitamin B12 deficiency can contribute to psychiatric symptoms such as depression, anxiety, mood swings, and even psychosis. Vitamin B12 deficiency can cause peripheral nerve damage known as peripheral neuropathy. When this happens, you may experience symptoms such as numbness, tingling, and pain in your hands and feet. Severe deficiency can cause damage to the optic nerve, resulting in optic neuropathy. This can lead to vision problems and even vision loss if not treated immediately. Vitamin B12 deficiency in pregnant women can lead to fetal development problems and an increased risk of neural tube defects. For men, deficiency can lead to infertility and low sperm count.
