What are the signs of vitamin B12 deficiency?

What Are the Signs of Vitamin B12 Deficiency? Vitamin B12 is essential for nerve function, red blood cell production, and DNA synthesis. A deficiency in B12 can lead to various symptoms, including: 1. Fatigue and Weakness One of the earliest signs of B12 deficiency is fatigue and a general sense of weakness. This is due to a lack of red blood cell production, which means less oxygen is delivered to your body’s cells. 2. Neurological Symptoms B12 deficiency can lead to neurological symptoms, including numbness or tingling in the hands and feet, difficulty walking, memory loss, and cognitive difficulties. Over time, untreated B12 deficiency can lead to permanent nerve damage. 3. Pale or Jaundiced Skin A lack of B12 can cause the skin to appear pale or jaundiced due to the reduced production of red blood cells and the breakdown of these cells. 4. Shortness of Breath and Dizziness Anemia caused by B12 deficiency can result in shortness of breath and dizziness, especially during physical activity, as your body struggles to get enough oxygen. 5. Glossitis and Mouth Ulcers Glossitis (inflammation of the tongue) and mouth ulcers are common in people with B12 deficiency. The tongue may become swollen, red, and painful. Conclusion Vitamin B12 deficiency can manifest in a range of symptoms, including fatigue, neurological issues, pale skin, shortness of breath, and oral problems. If you suspect you have a B12 deficiency, it’s important to consult a healthcare provider for proper diagnosis and treatment.
