WHAT IS VITAMIN B12?
The other name of vitamin B12 or the chemical name of vitamin B12 is cobalamin, it is a most complex form of all B- vitamins. It is a water-soluble vitamin.
This means that it can dissolve in water and transport through the bloodstream.
It is present only in the animal source and can be produced through bacterial fermentation in industries

WHAT DOES VITAMIN B12 DO?
Vitamin B12 plays an important role in your body. It helps in the production of red blood cells(RBC) and the synthesis of DNA. Also, It keeps the nervous system healthy.
it is essential for the functioning of all cells especially those of gastrointestinal tract, nervous system and bone marrow. It is critical during pregnancy for the baby’s developing brain and nervous system.
CAUSES OF DEFICIENCY OF VITAMIN B12
Deficiency of vitamin B12 causes a wide range of health issues. Mostly causes of the deficiency are seen in people who are on a vegetarian diet. If persisted for too long, its deficiency can cause severe neurological damage. It is also harder to absorb it for the ageing body
1. Pernicious anaemia
It is the failure of absorption of this Vitamin by the stomach due to some intrinsic factors (protein in the stomach). Basically the immune system, body’s natural defence mechanism, attacks your own body cells. This is due to the lack of vitamin in the diet. Thus, the bone marrow is not able to produce mature RBCs but releases a fewer number of large cells called macrocytes into blood circulation, which results in the decreased capacity of RBCs to carry haemoglobin. This causes pernicious anaemia.
2. Conditions affecting the intestines
Conditions like celiac disease, Crohn’s disease, bacterial growth, parasite affects the small intestines which make it harder for the absorption of Vitamin.
3. During Infancy, Failure to Thrive
During infancy, failure to thrive(when the child does not gain weight at the expected rate) delayed development, movement disorder and megaloblastic anaemia ( when red blood cells are not produced properly)are the causes for the deficiency.
4. Conditions affecting the stomach
Conditions like gastrointestinal surgery like gastrectomy can prevent the absorption of vitamin B12. This situation can become one of the causes for the deficiency.
Sometimes medicines also disrupt the absorption process of vitamin B12 and reduce the amount in the body. As medicine disturbs the intrinsic factor of the stomach.
6. Psychological issues
Long term vitaminB12 deficiency might cause you to feel confused or depressed. It can later cause dementia and poor memory.
Now after knowing the causes of vitamin b12 deficiency, let’s understand about which groups are at risk of its deficiency and its deficiency symptoms.

2. Individuals with gastrointestinal (GI) disorders and who had gastrointestinal surgery-
Individuals suffering from gastrointestinal disorders like celiac disorder and Crohn’s disease are most likely to have a deficiency of vitaminB12, because of the GI tract disorder the small intestine is unable to absorb the vitamin to maintain a healthy body.
Also due to the GI tract surgery, the cells in the intestine which helps in the secretion of hydrochloric acid and intrinsic factors gets lost and becomes one of the causes of vitamin deficiency in the body.
3. Older adults
Decreased secretion of hydrochloric acid in older adults, results in the decreased absorption of it. Also because of the decreased amount of hydrochloric acid leads to the increased growth of normal intestinal bacteria which consumes the vitamin b12 available in the body. This leads to its deficiency in the body.
4. Strict Vegetarians
As it is only available in the animal source, the person consuming only vegetarian and vegan diet is at greater risk of its deficiency. Fortified foods like breakfast cereals and nutritional yeasts are the only source of having vitamin B12 in the vegan diet.
