Vitamin B12 is an essential nutrient that plays a critical role in various body functions, including the formation of red blood cells, DNA synthesis, and proper nervous system function.

However, like any other vitamin deficiency, a B12 deficiency can affect your health and well-being. In this article, we’ll explore seven warning signs indicating a Vitamin B12 deficiency and what you can do about it.

What Causes Vitamin B12 Deficiency?

Vitamin B12 is primarily found in animal products like meat, fish, and dairy. Therefore, people who consume a vegetarian or vegan diet or have impaired digestion may develop a B12 deficiency. Other causes of Vitamin B12 deficiency include:.

Pernicious anemia, a condition that inhibits the production of intrinsic factor (a protein that aids in the absorption of Vitamin B12)
Gastrointestinal disorders such as celiac disease, inflammatory bowel disease, or Crohn’s
Malabsorption syndrome, which affects the body’s ability to absorb nutrients properly
Gastric bypass surgery that removes a portion of the stomach, which may hinder the body’s ability to absorb B12 properly
Medications such as metformin, proton pump inhibitors, and H2 blockers may interfere with B12 absorption

7 Warning Signs of Vitamin B12 Deficiency

1. Fatigue

Persistent fatigue or weakness is a common symptom of B12 deficiency. This occurs because the body doesn’t produce sufficient red blood cells to transport oxygen throughout the body.

If you feel tired, even after a good night’s sleep, you should consider checking your B12 levels.

2. Dizziness

One of the first symptoms of B12 deficiency is dizziness or lightheadedness. This is because the deficiency causes anemia, leading to an insufficient supply of oxygen to the brain.

3. Numbness and Tingling Sensation

Vitamin B12 is essential for proper operation of the nervous system. A deficiency can cause a numbing and tingling sensation in the arms, legs, hands, and feet.

4. Difficulty Breathing

As Vitamin B12 aids in red blood cell formation, a deficiency can cause a decreased supply of oxygen, making it hard to breathe. In severe cases, this can lead to chest pain, shortness of breath, and even heart palpitations.

5. Pale Skin

A decrease in red blood cell production due to a B12 deficiency can cause pale and jaundiced skin. If you develop this sign, you should consult your doctor immediately.

6. An Unsteady Gait

The deficiency of Vitamin B12 can also affect your mobility, making it challenging to walk smoothly due to numbness in your feet. Patients may also develop muscle weakness.

7. Forgetfulness and Cognitive Decline

Another significant role that Vitamin B12 plays in the body is that it aids in the proper functioning of the brain. Deficiency can cause confusion, forgetfulness, and other cognitive declinations.

What Can You Do to Prevent or Treat B12 Deficiency?

If you’re a vegetarian or vegan, you should add Vitamin B12-fortified foods, such as cereals and nutritional yeast, to your diet, as well as take vitamin B12 supplements.

If you have gastrointestinal issues or had gastric bypass surgery that interferes with B12 absorption, your doctor may recommend B12 shots, nasal sprays, or high-dose oral supplements to manage the deficiency.

Conclusion

Vitamin B12 is essential for optimal health. If you notice any of the above-mentioned signs of deficiency, consult your doctor immediately. Incorporating Vitamin B12-rich foods or supplements can help you manage or prevent B12 deficiency.

Don’t neglect the potential harm caused by a lack of B12 – take preventive measures for your overall well-being.
