What is Anemia?Anemia is caused due to reduced red blood cells in the blood. Hemoglobin is one of the most important proteins in the red blood cells. Its main function is to carry oxygen and deliver it to all the parts of the body. In case the level of hemoglobin is less it results in anemia. Due to low hemoglobin levels the tissues, organs, etc do not get enough oxygen and result in symptoms of anemia as the body is unable to work properly. The different types of anemia are:

  • Iron-deficiency anemia
  • Vitamin deficiency anemia
  • Aplastic anemia
  • Hemolytic anemia
  • Sickle cell anemia
  • Anemia due to other diseases

Anemia CausesRed blood cells need iron, folate, and vitamin B12 for their production and sustenance in the body. The average lifespan of these RBCs in the body is about 3 months and about 1% of it is replaced every day. If for any reason there is an increase in RBC destruction and reduction in production it causes anemia. Causes for the decrease in RBC production:

  • Hypothyroidism
  • Imbalance in the production of preproprotein in the kidney results in reduced RBC production.
  • Lack of dietary iron, folate and Vitamin B12

Causes of increased RBC destruction:

  • Thalassemia and sickle cell anemia (a genetic disorder)
  • Surgery, injury, trauma
  • Menstruation, childbirth
  • Endometriosis
  • Lesions in the GI tract
  • Cirrhosis
  • Fibrosis
  • Hemolysis due to certain medications

How is Anemia Diagnosed?Blood tests are one of the common diagnostic tests that the healthcare provider uses to check if you have anemia.

  • CBC or the complete blood count test is performed to know the parameters of RBC like the number, shape, and size. It can also help in finding if there is iron and Vitamin B12 and B9 deficiency.
  • Urine tests know if the patient has hemolytic anemia.
  • A colonoscopy may be done to determine if there is gastrointestinal bleeding. This is done based on the severity of the symptoms.
  • A biopsy is also performed in rare cases of anemia type to test the bone marrow tissue.

How is Anemia Treated?Based on the test results, the doctor will determine if the underlying cause is a poor diet or a health issue. The anemia treatment options, in any case, will include:

  • Dietary changes with more focus on foods that are rich in iron and Vitamin C.
  • Prescribing iron supplements.
