Hello!
Vitamin B12 deficiency anemia is a blood problem that occurs when there is not enough of this vitamin in your body.
Vitamin B 12 deficiency can occur due to inadequate dietary intake or impaired absorption. The condition is commonly asymptomatic, but can also present as anemia and called megaloblastic anemia and can be diagnosed by a peripheral smear examination.
You must eat enough foods that contain vitamin B12, such as meat, poultry, shellfish, eggs, and dairy products.
Follow up with a physician to get yourself prescribed with vitamin B12 supplements.
Take care!
My mom can't absorb b12 and she takes injections of it every month she no longer has any related problems.
