Vitamin B12 is an essential nutrient that plays a crucial role in red blood cell formation, neurological function, and DNA synthesis. A deficiency can lead to serious health issues, so understanding its symptoms, causes, and dietary sources is important.

Symptoms of Vitamin B12 Deficiency

Anemia: A lack of vitamin B12 can cause megaloblastic anemia, leading to fatigue and weakness.
Fatigue and Weakness: People with low B12 levels often experience chronic tiredness and lack of energy.
Neurological Issues: Symptoms such as numbness, tingling in the hands and feet, balance problems, and nerve damage may occur.
Breathlessness and Heart Palpitations: Severe deficiency may cause irregular heartbeats and shortness of breath.
Cognitive Issues: Memory problems, difficulty concentrating, and brain fog can be linked to low B12 levels.
Causes of Vitamin B12 Deficiency
Dietary Deficiency: Those following a strict vegetarian or vegan diet may lack B12, as it is primarily found in animal-based foods.
Malabsorption Issues: Conditions such as gastritis, Crohn’s disease, celiac disease, and pernicious anemia can impair the body’s ability to absorb vitamin B12.
Aging: Older adults may have reduced stomach acid levels, which are necessary for B12 absorption.
