Key Causes, Clinical Features, and Treatment Approaches

Anemia is a blood disorder wherein there is a decrease in the number of red blood cells in a human body. There are several types of anemias out of which normocytic normochromic anemias is one of them. Normocytic normochromic anemia is one of the most common forms of anemia which is usually found along with other chronic diseases.


A mild normocytic normochromic anemia is a common occurrence found as a consequence of other diseases such as anemia due to chronic disorders or other disorders which include renal failure, acute blood loss, etc. Thus, mostly normocytic normochromic anemia is a case of anemia that occurs due to other prolonged disease conditions.


Normocytic Normochromic Anemia Causes

As given above, normocytic normochromic anemia is a type of anemia that tends to accompany certain chronic diseases. The symptoms of normochromic anemia are similar to regular anemia and hence it is diagnosed by regular blood tests. For treating normochromic anemia the focus is on solving first the cause of the chronic disease and then providing the normal treatments for curing anemia. While diagnosing for the case of normochromic anemia the normochromic red blood cells appear to be normal in shape and size under the microscope with no characteristic difference as in the case of sickle cell anemia.


Normocytic anemia can be congenital in some cases i.e. a child is born with the condition of normocytic anemia. Sometimes the disease can be a result of complications arising due to certain medications as well. But most often, as mentioned above, normocytic anemia is caused as a result of other chronic diseases. Because of this, it is also known as the anemia chronic disease or anemia of inflammation. Also, one of the harmful effects of normocytic anemia on the body can be inflammation in certain parts of the body or the entire body which is also a contributing factor to it being known as anemia of inflammation. The inflammation can cause the downgrade of the body’s immune system and also result in a reduction of red blood cell production or production of weaker red blood cells that die fast and cannot be replenished in a timely manner. 


Normocytic hypochromic anemia is another type of anemia in which the red blood cells have a distinct green tinge. The normocytic hypochromic anemia has similar symptoms to normal anemia like lack of energy, shortness of breath, headaches, etc. which is also observed in other forms of anemia. In the case of normocytic hypochromic anemia the central region of the red blood cells appears to be increased in size as compared to the normal red blood cells. The most common causes for this type of anemia are the deficiency in iron content and thalassemia. 


Microcytic normochromic anemia is another type of anemia caused due to prolonged chronic diseases. Microcytic normochromic anemia is so named because of the size of the red blood cells in the diseases. This size is the vital difference between microcytic normochromic anemia and normocytic normochromic anemia. In a predominantly normocytic normochromic case, there is no visible change in the size and shape of the red blood cells whereas in the microcytic normochromic anemia the red blood cells are smaller in size as compared to the normal red blood cells. The similarity in both cases is that both of them are the result of severe chronic diseases and continuous inflammation of the body. 


The diseases that are mostly and very closely associated with the normocytic and microcytic normochromic anemia are - cancer, infections, chronic kidney diseases, heart failure, obesity, rheumatoid arthritis, lupus,  vasculitis (i.e. inflammation of the blood vessels), sarcoidosis (i.e. the inflammatory diseases affecting the lungs the lymph system), inflammatory bowel disease, and bone marrow disorders. Malnutrition is another severe cause of normochromic anemia. In some cases, pregnancy is also an added risk factor for the cause of normochromic anemia.


Symptoms, Diagnosis and Treatment of Normocytic Normochromic Anemia

Symptoms:

The symptoms of normocytic anemia are very slow to develop, The common symptoms of this or any form of anemia as stated above are feelings of fatigue and tiredness, and a pale complexion. The disease can also cause you to feel dizzy or lightheaded, have breath shortness, feel weak, etc. One important point to note is that since normocytic normochromic anemia is usually a result of chronic disease, the symptoms that indicate this can be easily neglected. Hence, a medical diagnosis of the condition along with treatment of other prolonged diseases can shed light on this matter, in case a patient is suffering from any of the above-mentioned types of anemia.


Diagnosis:

To diagnose any kind of anemia a routine blood test is compulsory. A routine complete blood count (CBC) can bring to light the condition of the red blood cells and will help in identifying if a patient is suffering from any form of anemia or not. A CBC test provides a detailed report of the red blood cells, white blood cells, platelet levels, and other markers of blood health. This test can be a part of the regular check-up or whenever there is abnormal bleeding even on a small bruise which is definitely one of the symptoms of anemia. Once anemia has been detected further testing can be done and is required for specific determination of the kind of anemia before any treatment can be provided.


Once the tests show deficiency, the patient has to take it very seriously, he should consult with the doctor and follow the routine suggested by him. For instance, he may suggest a few medications, dietary changes (inclusion of more iron-rich foods and fruits such as spinach, banana, carrots, and many more to name). Here it is to be noted that only a few day care will not be sufficient as it needs time. But yes, if proper care is followed then one can start experiencing the changes within 15 days as well. 


For most normocytic or microcytic normochromic anemia, it is necessary to first cure the chronic disease. Along with the identification of the primary cause of the disease and its treatment, subsequent and simultaneous treatment of the anemia can be done. General treatments involve anti-inflammatory medications in case of diseases like rheumatoid arthritis, strong antibiotics in case of bacterial infections, shots of Epogen in severe cases to boost the production of red blood cells, and in some cases blood transfusions, etc.

FAQs on Normocytic Normochromic Anemias: Complete Student Guide

1. What is normocytic normochromic anemia?

Normocytic normochromic anemia is a type of anemia where the red blood cells (erythrocytes) are of a normal size and contain a normal amount of hemoglobin. The term 'normocytic' refers to the normal size of the cells, and 'normochromic' refers to their normal color, which indicates a standard concentration of hemoglobin. However, despite the normal appearance of individual cells, the total number of red blood cells in circulation is low, leading to anemia.

2. What do the terms 'normocytic' and 'normochromic' specifically mean on a blood test report?

On a complete blood count (CBC) report, these terms relate to specific red blood cell indices:

  • Normocytic means the Mean Corpuscular Volume (MCV), which measures the average size of your red blood cells, is within the normal range (typically 80-100 femtolitres). The cells are not too small (microcytic) or too large (macrocytic).
  • Normochromic means the Mean Corpuscular Hemoglobin Concentration (MCHC), which measures the average concentration of hemoglobin inside a single red blood cell, is also normal. The cells are not pale (hypochromic).
Therefore, it points to a problem with the production or survival of red blood cells, rather than a defect in their size or hemoglobin content.

3. What are the most common causes of normocytic normochromic anemia?

The primary causes of normocytic normochromic anemia are related to an underproduction of red blood cells or an increase in their destruction or loss, without affecting the cells' characteristics. Common causes include:

  • Anemia of chronic disease: Conditions like chronic kidney disease, cancer, rheumatoid arthritis, and other chronic inflammatory diseases.
  • Acute blood loss: Sudden, significant blood loss from trauma or surgery.
  • Aplastic anemia: Bone marrow failure leading to insufficient production of all blood cells.
  • Hemolytic anemia: Premature destruction of red blood cells.
  • Early-stage iron deficiency: Before the cells become small and pale (microcytic and hypochromic).

4. What are the typical symptoms a student might notice with normocytic normochromic anemia?

The symptoms are generally the same as other types of anemia and result from the reduced oxygen-carrying capacity of the blood. A student might experience:

  • Persistent fatigue and lack of energy.
  • Paleness of the skin, nail beds, and inner eyelids.
  • Shortness of breath, especially with exertion.
  • Dizziness or lightheadedness.
  • Difficulty concentrating in class.
  • A rapid heartbeat (tachycardia).
Since these symptoms can develop gradually, they might initially be dismissed as simple tiredness.

5. How does normocytic normochromic anemia differ from microcytic or macrocytic anemias?

The key difference lies in the size of the red blood cells, as indicated by the Mean Corpuscular Volume (MCV).

  • Normocytic Anemia: Normal-sized RBCs (MCV 80-100 fL). It's often caused by chronic diseases or acute blood loss.
  • Microcytic Anemia: Small RBCs (MCV < 80 fL). The most common example is iron-deficiency anemia, where there isn't enough iron to make hemoglobin, resulting in smaller, paler cells.
  • Macrocytic Anemia: Large RBCs (MCV > 100 fL). This is typically caused by deficiencies in Vitamin B12 or folate, which are crucial for DNA synthesis during red blood cell production.

6. Why is normocytic normochromic anemia often called 'anemia of chronic disease'?

It is frequently called 'anemia of chronic disease' (ACD) because long-term inflammatory, infectious, or cancerous conditions are its most common cause. In these chronic states, the body's inflammatory response can interfere with normal red blood cell production in several ways:

  • It can disrupt how the body uses and stores iron.
  • It can decrease the production of erythropoietin (EPO), a hormone from the kidneys that stimulates red blood cell production.
  • It can shorten the survival lifespan of red blood cells.
Because the underlying issue is inflammation and not a nutrient deficiency, the cells that are produced are of normal size and hemoglobin content, just fewer in number.

7. How does the treatment for normocytic normochromic anemia differ from treating other anemias?

The treatment approach is fundamentally different because it focuses on the underlying cause rather than simple supplementation. For example, while iron-deficiency anemia is treated with iron supplements and macrocytic anemia with Vitamin B12/folate, treating normocytic normochromic anemia involves:

  • Managing the chronic disease: Controlling the inflammation from conditions like rheumatoid arthritis or treating an underlying infection or cancer.
  • Erythropoietin (EPO) stimulating agents: In cases of chronic kidney disease, injections of EPO can be given to stimulate the bone marrow.
  • Blood transfusions: For severe anemia or acute blood loss to quickly restore red blood cell levels.
Simply taking iron or vitamin supplements is usually ineffective unless a concurrent deficiency is also diagnosed.
