Breathlessness and Dizziness
Vitamin B12 deficiency could result in anemia. People who are anemic usually experience a lack of healthy red blood cells to carry enough oxygen to the body’s tissues. Normally, anemia makes individuals feel tired and weak, which includes feeling dizzy and breathless.
The anemia that occurs due to B12 deficiency is usually megaloblastic, making the bone marrow’s red blood cells weakened. Note that there are different causes of breathlessness and dizziness. Hence, it’s important to speak to the doctor to know the exact reasons for feeling this symptom.
Weakness and Fatigue
Vitamin B12 deficiency causes body fatigue. When the body doesn’t have enough vitamin B12 to make red blood cells, weakness may occur. When the body cannot transport oxygen to the body cells appropriately, it causes a significant level of fatigue in the body.
In older individuals, the condition is usually called pernicious anemia, which is an autoimmune condition. People with this condition don’t get enough intrinsic factor, which is an important protein for the body. Note that weakness and fatigue are a sign of various medical conditions, and it’s advisable to speak to a licensed doctor before taking any step on treatment.
Conclusion
Vitamin B12 deficiency is a common condition, and it can occur in different ways, making it hard to identify. It’s imperative to speak to a doctor if any of the signs of the condition is observed.
