Vitamin B12 Deficiency Symptoms: Vitamin B12 is an essential nutrient, which is very important for the functioning of our body. This vitamin is essential for DNA synthesis, energy production and central nervous system function. Research says that 20 per cent of people above 60 are deficient in this vitamin. Which can usually be due to an incomplete diet or any medical condition.

With age, our body is not able to absorb Vitamin B12 properly from food, and this deficiency is seen in elderly people. But this does not mean that young people cannot struggle with the deficiency of this vitamin. Like all other nutrients, vitamin B is also very important for health, but still it is often ignored.

Let us know the symptoms of Vitamin-B12 deficiency, on whose appearance contact the doctor immediately.

1. Exhaustion
If your body is deficient in Vitamin B12, you will feel tired. Your body needs B12 to function properly. If B12 levels deteriorate, it leads to a decline in red blood cells. When your body can't make enough healthy red blood cells to carry oxygen to the tissues, you feel weak and tired.

2. Yellowing of the skin
Vitamin-B12 deficiency can cause yellow or discoloured skin. B12 anaemia can cause discoloured skin due to the lack of healthy red blood cells in the body. B12 deficiency can also lead to jaundice, which causes the yellowing of your skin and eyes.

3. Headache
B12 deficiency can also have neurological side effects, including headaches. Even headache is the most common symptom of Vitamin-B12 deficiency. Research has shown that B12 deficiency is common in people who suffer from frequent headaches.

4. Depression-like symptoms
Vitamin B12 is essential for central nervous system function, so a deficiency in this nutrient can affect your mental health. In particular, B12 deficiency may increase the risk of developing depression. Along with depression, vitamin B12 deficiency can also trigger other psychiatric problems, including psychosis and mood swings.

5. Stomach problems
B12 deficiency can cause diarrhoea, nausea, constipation, bloating, gas, and other abdominal problems. This problem can be felt by both adults and children.

6. Difficulty focusing
Because B12 deficiency harms the central nervous system, it can cause people to feel fuzzy, as well as have difficulty concentrating or completing tasks. Older people in particular may experience these symptoms, as vitamin B12 deficiency increases with age.
