News Topical, Digital Desk : Do you know how important vitamin B12 is for our health? In fact, vitamin B12 plays a crucial role in everything from DNA synthesis to the formation of red blood cells. Therefore, we should be cautious about vitamin B12 deficiency, as it can cause various health problems. 

Vitamin B12 deficiency causes certain symptoms in the body, which are important to recognize. These symptoms initially appear quite common, making them difficult to recognize. Let's explore the symptoms of vitamin B12 deficiency. 

Fatigue and weakness

This is the most common and earliest symptom. Vitamin B12 deficiency prevents the body from producing healthy red blood cells, leading to anemia. Red blood cells carry oxygen throughout the body. A deficiency can prevent adequate oxygen from reaching various parts of the body, causing a person to feel constantly tired, lethargic, and weak.

Nervous system problems

Vitamin B12 plays a vital role in maintaining a protective layer around the nerves. A deficiency can damage this layer, leading to impaired nervous system function. Symptoms include:

  • Tingling or numbness – A pins and needles feeling or numbness in the hands, feet, or throughout the body.
  • Muscle weakness – problems with walking, trouble maintaining balance.
  • Memory loss - Vitamin B12 deficiency directly affects the brain, leading to memory loss, difficulty focusing, and confusion. Long-term deficiency can even lead to serious problems like dementia.

Yellowing of the skin

Vitamin B12 deficiency causes anemia. This can cause yellowing of the skin and eyes. Therefore, yellowing of the skin without any other cause may be a sign of vitamin B12 deficiency.

Swollen tongue and mouth ulcers

Sometimes, a vitamin B12 deficiency causes swelling, redness, and pain in the tongue. The tongue may feel smooth and tender. Frequent mouth ulcers can also be a symptom of this deficiency.

Impact on mental health

In addition to physical symptoms, vitamin B12 deficiency has a profound impact on mental health. A deficiency can cause mood swings, irritability, depression, and anxiety. This is due to the impact on neurotransmitters like serotonin and dopamine in the brain.
