GENERAL KNOWLEDGE

Detailed explanation-1: -Pernicious anemia is a type of vitamin B12 anemia. The body needs vitamin B12 to make red blood cells. You get this vitamin from eating foods such as meat, poultry, shellfish, eggs, and dairy products. A special protein, called intrinsic factor (IF), binds vitamin B12 so that it can be absorbed in the intestines.

Detailed explanation-2: -Pernicious anemia usually is easy to treat with vitamin B12 shots or pills. If you have severe pernicious anemia, your doctor may recommend shots first. Shots usually are given in a muscle every day or every week until the level of vitamin B12 in your blood increases.

Detailed explanation-3: -Pernicious anaemia causes your immune system to attack the cells in your stomach that produce the intrinsic factor, which means your body is unable to absorb vitamin B12.

Detailed explanation-4: -Helps with red blood cell formation and anemia prevention Vitamin B12 plays a vital role in helping your body produce red blood cells. Low vitamin B12 levels cause a reduction in red blood cell formation and prevent them from developing properly ( 2 ).

Detailed explanation-5: -Introduction Parenteral injection of cyanocobalamin (Vitamin B12) is well established as an effective and reliable treatment for pernicious anemia.
