Question 1

What exactly is vitamin B12 deficiency?

Accepted Answer

Vitamin B12 deficiency means your body doesn't have enough B12, a nutrient your blood needs to work properly. Without enough B12, your body can't make healthy red blood cells, which can lead to anemia. (Source: MedlinePlus)

Question 2

How does not having enough vitamin B12 cause anemia?

Accepted Answer

Your body uses B12 to make red blood cells that carry oxygen through your blood. When you don't have enough B12, you can't make enough healthy red blood cells, so your blood can't carry enough oxygen to the rest of your body. (Source: MedlinePlus)

Question 3

Can a poor diet lead to this kind of anemia?

Accepted Answer

Yes, a diet that doesn't have enough vitamin B12 can cause this type of anemia. B12 is found mainly in animal products like meat, fish, eggs, and dairy, so people who don't eat these foods are at higher risk. (Source: MedlinePlus)

Are there other causes besides diet that can make me deficient in B12?

Accepted Answer

Yes, besides diet, other causes include problems absorbing B12 from food, certain stomach surgeries, and some digestive conditions. Some medicines can also make it harder for your body to use B12. (Source: MedlinePlus)

Question 13

Can eating more foods with B12 help me get better?

Eating more B12-rich foods can help if your deficiency is from diet alone, but if your body can't absorb B12 properly, you'll need supplements. Your doctor will tell you if diet changes alone are enough. (Source: MedlinePlus)

Question 14

What happens if I don’t follow the treatment plan exactly?

Question 18

Can taking too much B12 hurt me?

Accepted Answer

No, taking too much B12 is very unlikely to hurt you because your body only uses what it needs and gets rid of the rest. B12 is a water-soluble vitamin, so excess amounts are excreted in urine. (Source: MedlinePlus)

Accepted Answer

How long you need B12 treatment depends on what's causing your deficiency. If it's from diet, you might only need it short-term, but if your body can't absorb B12, you may need lifelong treatment. (Source: MedlinePlus)
