Deficiency anemia is anemia caused by low vitamin B-12 and folate in the blood.

Deficiencies in vitamin B-12 and folate can lead to anemia if you don’t get enough nutrients from your diet.

A deficiency in these nutrients causes the body to create red blood cells that are excessively big and ineffective. So they can’t transfer oxygen very well.

Symptoms include fatigue, breathlessness, and dizziness. Vitamin deficits can be remedied with the help of oral or intravenous supplements.


Anemia caused by a vitamin deficiency usually takes months or years to develop. When a deficiency becomes more severe, the signs and symptoms become more noticeable. These are some examples:

  • Fatigue
  • Breathlessness
  • Dizziness
  • Yellow or light-colored skin
  • Heart palpitations and tachycardia
  • Loss of weight
  • Tingling or numbness in the hands or feet.
  • Myofascial atrophy
  • People’s personalities shift throughout time.
  • shaky motions
  • Mental lapses or lapses of memory

Inadequacy in vitamin B-12

Many factors might contribute to a deficiency in vitamin B12.

Diet. Because meat, eggs, and milk are the primary sources of vitamin B-12, those who don’t consume these items may need to supplement their diets with the vitamin. Some breakfast cereals and nutritional yeast products have been fortified with vitamin B-12.

Pernicious anemia. When the body’s immune system destroys cells in the stomach that create intrinsic factors, this disease occurs. B-12 cannot be absorbed in the intestines without this substance.

Surgical procedures to reduce one’s stomach size. Surgically removing sections of your stomach or intestines can lower the number of intrinsic factors generated and the area available for vitamin B-12 absorption.

The trouble with the digestive system. Crohn’s illness and celiac disease, and tapeworms ingested via eating infected seafood can cause vitamin B-12 absorption to be hindered.

Folic acid deficiency

In addition to dark green leafy vegetables and liver, folate is also known as vitamin B-9. For example, a lack of folate can arise if people do not consume meals rich in vitamins or their bodies are incapable of absorbing it.

Insufficient absorption can be caused by:

  • Celiac disease and other gastrointestinal ailments
  • a substantial portion of the intestines is surgically removed or bypassed
  • excessive use of alcoholic beverages
  • Some anti-seizure medications are available only by prescription.
  • Pregnant women, breastfeeding women, and those on dialysis for kidney illness all have an increased need for folate.

Deficiency in folate during pregnancy can lead to birth abnormalities. However, the prevalence of folate insufficiency in nations that frequently add folate to dietary products such as breads, cereals, and pasta has decreased.
