Vitamin B12 deficiency is a condition caused by a lack of vitamin B12 in the body. It can lead to a number of serious health problems if left untreated. It is important to be aware of the warning signs of vitamin B12 deficiency and to seek medical attention if you experience any of them.
Common warning signs of vitamin B12 deficiency include fatigue, weakness, pale skin, shortness of breath, rapid heartbeat, dizziness, numbness or tingling in the hands and feet, and vision problems. Other symptoms may include anemia, which can cause a decrease in red blood cells and a decrease in the amount of oxygen carried to the body’s organs, brain fog, confusion, and difficulty concentrating.
Those at higher risk of developing a vitamin B12 deficiency include older adults, vegetarians and vegans, pregnant women, people with gastrointestinal disorders such as Crohn’s disease, and those with certain autoimmune disorders.
If you think you may be suffering from a vitamin B12 deficiency, it is important to seek medical advice. Your doctor will be able to carry out a physical examination and may ask for a blood test to confirm the diagnosis. Treatment typically involves taking oral or injected supplements, and making dietary changes to ensure an adequate intake of B12.
