Causes of Vitamin B12 Deficiency: Nowadays, people are experiencing lethargy even after eating and drinking. Let us explain which vitamin deficiency causes this.

How to recognize Vitamin B12 deficiency?
How To Identify Vitamin B12 Deficiency Early: As human lifestyles are changing, they are also facing various problems. Nowadays, despite eating right, many people feel constant fatigue, weakness, and lack of focus. A major reason behind this could be vitamin B12 deficiency, which is often overlooked. According to a study published in the Indian Journal of Endocrinology and Metabolism, about 47 percent of people in North India are found to be deficient in it. Let us tell you how to overcome this deficiency.
Why is Vitamin B12 important?
Vitamin B12 is vital for the body. It helps form red blood cells, strengthen the nervous system, and convert food into energy. A deficiency can gradually weaken the body and lead to serious long-term problems. Deficiency can occur not only through dietary intake but also due to improper absorption. According to a report by the Indian Council of Medical Research, this problem is more common in vegetarians, as B12 is primarily found in animal-based foods. Additionally, aging and prolonged use of certain medications can also contribute to deficiency.
What are the symptoms of deficiency?
Early symptoms are often mild, such as feeling constantly tired, having trouble concentrating, or feeling a little short of breath. However, over time, these problems can progress to include tingling in the hands and feet, memory loss, and loss of balance. That's why it's crucial to recognize these signs early.
In which things is it found?
Regarding diet, eggs, fish, chicken, and dairy products are considered good sources for non-vegetarians. Vegetarians should include milk, yogurt, and cheese, as well as fortified foods like cereals and plant-based milks, as common vegetarian foods are very low in B12. In some cases, diet alone cannot address the deficiency.
According to experts, if B12 deficiency persists for a long time, it can cause weakness, brain fog, and permanent neurological damage. In such cases, supplements or injections may be necessary as per doctor's advice. This problem can be easily prevented with regular checkups, a balanced diet, and timely treatment.
