Vitamin Deficiency Anaemia

Vitamin deficiency anaemia occurs when the body does not have enough folate and B12 or has trouble absorbing these vitamins. Without enough folate and B12, your red blood cells will be too large and unable to carry oxygen around the body efficiently.

Symptoms

Common symptoms of vitamin deficiency anaemia include:

  • Being tired all of the time
  • Dizziness
  • Being short of breath
  • Irregular heart rhythm
  • Pale or yellow skin
  • Tingling in the feet or hands
  • Muscle weakness
  • Unexpected weight loss
  • Confusion
  • Unsure movement
  • Personality changes

Symptoms usually appear over the course of months or even years and usually get worse as time goes on.

Causes & Risk Factors

Folate and vitamin B-12 deficiencies are usually caused by dietary insufficiency or an absorptive disorder. Common causes of vitamin deficiency anaemia include:

  • Diet may contribute to a lack of Vitamin B12 and folate. Vitamin B12 is mainly found in dairy products like eggs, milk, meat, and some foods with Vitamin B12 added, like cereals. Folate is mainly found in leafy greens. If someone is not receiving Vitamin B12 or folate through their diet, they must take supplements to compensate for the deficiency.
  • Gastric surgery involves parts of the intestines or stomach removed. If you have had gastric surgery, the amount of chemicals your body produces to absorb B12 and folate has probably decreased, and the physical space you have to absorb B12 and folate has, too.
  • Pernicious anaemia happens when the immune system attacks cells in the digestive system that produce something called intrinsic factor. Intrinsic factor is necessary for the absorption of Vitamin B12, and without it, Vitamin B12 will not be absorbed from foods into the body.
  • Other intestinal issues, like celiac disease and Crohn’s disease, can contribute to the body’s inability to properly absorb Vitamin B12 or folate.
  • Excessive alcohol consumption and some prescription drugs can contribute to folate absorption issues.

Risk factors for vitamin deficiency anaemia include a family history of the disease, autoimmune disease, maintaining a vegetarian diet, being an older adult, HIV, and Crohn’s disease.

Diagnosis & Complications

If your doctor suspects you or your child is struggling with vitamin deficiency anaemia, they can confirm the diagnosis with a blood test. They will look at any red blood cell abnormalities, the amount of folate and Vitamin B12 in the blood, and indicators that the body is attacking cells in the digestive system that produce intrinsic factor to see if you have pernicious anaemia.

Complications of vitamin deficiency anaemia include:

 

  • Birth defects – folate is essential to the healthy development of a foetus
  • Nervous system disorders – vitamin B12 is essential for the maintenance of a healthy nervous system
  • Digestive system disorders – pernicious anaemia can lead to more serious issues, increasing the risk of cancers in the stomach or intestines

See a doctor immediately if you’re experiencing any symptoms of vitamin deficiency anaemia.

Treatment & Management

Vitamin deficiency anaemia is treated with vitamin supplements. If you have pernicious anaemia, you may need intravenous infusions of Vitamin B12 for the rest of your life. Vitamin deficiency anaemia can be prevented by eating a healthy diet with a lot of variety.

Consider including beef, fish, chicken, eggs, dairy products, leafy greens and vegetables, fruits like bananas and melons, enriched grains, and beans to ensure you get plenty of Vitamin B12 and folate. Pregnant women and those who have recently had gastric surgery will likely need to supplement dietary vitamins with a multivitamin to accommodate their dietary needs.
