Vitamins and minerals are crucial for the balance of our bodies. If you have a lower than a particular threshold of vitamins or minerals in your body, it could lead to vitamin deficiency anemia.

Anemia is a health condition in which the patient lacks sufficient red blood cells required to carry oxygen throughout the body. It has various types and causes.  

Vitamins B9, B12, and C are certain vitamins whose deficiency can directly reduce the levels of red blood cells in the human body. One must consume adequate quantities of food rich in these vitamins to avoid this disease. 

About Vitamin Deficiency Anemia

There are specific vitamins that cause anemia when their levels in the body drop. These include:

  • Vitamin C – Vitamin C deficiency anemia can occur if you do not consume enough iron from plant-based or citrus foods. Besides, if you are a smoker, smoking can hamper your ability to absorb vitamin C from these food sources.
  • Vitamin B-12 – Vitamin B12 deficiency anemia can occur if you do not consume enough vitamin B12-rich foods, such as meat, eggs, and milk. 
  • Folate – Finally, leafy green vegetables and fruits are the primary sources of vitamin B9 or folate , and their inadequacy in your diet can also result in vitamin deficiency anemia.

Low quantities of other vitamins can cause other illnesses but do not cause anemia. Like other types of anemia, vitamin deficient anemia can cause issues with the proper functioning of the body.

Vitamin deficiency anemias are diagnosed by doctors through blood tests that check:

The red blood cells may appear large and underdeveloped in vitamin deficiency anemias related to lack of vitamin B-12 and folate. In advanced deficiencies, the numbers of platelets and white blood cells may also decrease and look abnormal under the microscope.

  1. The amount of vitamin B-12, folate and vitamin C in your blood: Vitamin B-12 and folate levels are measured at the same time as these deficiencies may cause similar signs and symptoms.

Additional tests for B-12 deficiency

  • Antibodies test: You may be advised a blood test to check for antibodies to intrinsic factor. The presence of antibodies indicates pernicious anemia.
  • Methylmalonic acid test: You may also be advised a blood test to check and determine the presence of a substance known as methylmalonic acid. The level of methylmalonic acid is higher in those with vitamin B-12 deficiency.
