Description

The absence of enough healthy red blood cells in the body is known as anaemia. Red blood cells carry oxygen to human tissues. Red blood cells normally spend 120 days in the body. Hemolytic anaemia causes the red blood cells in the blood to break down earlier than normal. Red blood cells play a key role in the delivery of oxygen from the lungs to heart and the rest of our body. The bone marrow produces these red blood cells. When the rate at which our bone marrow produces red blood cells is faster than the rate at which these cells are oxidised, hemolytic anaemia sets in.

a) There is a chance of either intrinsic or extrinsic hemolytic anaemia.

b) External haemolytic

Extrinsic hemolytic anaemia can manifest in a variety of ways, such as when the spleen seizes and destroys healthy red blood cells or when an immunological reaction occurs. It might also happen as a result of the destruction of red blood cells brought on by infections or cancer.

Internal hemolysis

Intrinsic hemolytic anaemia can happen when the red blood cells in the body makes no proper functions. Patients with sickle cell anaemia or thalassemia who have deficient haemoglobin usually inherit this condition. Other times, this condition may be brought on by an inherited metabolic disorder, such as in people with G6PD deficiency, or by red blood cell membrane instability, such hereditary spherocytosis. Any age might be affected by hemolytic anaemia.

Causes of hemolytic anaemia

It is possible for a doctor to be unable to determine what causes hemolytic anaemia. However, a lot of diseases and even some medications might exacerbate this problem. One of the most dangerous varieties of hemolytic anaemia is the one brought on by receiving red blood cells of the wrong blood type. Each person has a specific blood type (A, B, AB, or O). If we get blood that is not compatible with specialised immune proteins known as antibodies will attack the foreign red blood cells. This can be fatal when red blood cells are damaged very quickly. For this reason, medical practitioners must carefully confirm blood types prior to blood donation.

There are temporary causes for hemolytic anaemia. Hemolytic anaemia may be cured if a doctor is able to identify and treat the underlying cause.

The newborn may develop hemolytic disease if the mother and child have different blood types, which is typically caused by Rh incompatibility. This condition is also known as erythroblastosis fetalis. The ABO blood types (A, B, AB, and O) and the Rh factor status, which can be positive or negative, both affect a person's particular blood type. The positive and negative letters O, AB, A, and A are some examples. If both the mother's and the father's red blood cells exhibit the Rh factor, an infant who has hemolytic disease may be born.

The effects are identical to red blood cell transfusion reactions brought on by an ABO mismatch. If the baby's blood type is considered "foreign," the mother's body may launch an attack on the newborn. After her second pregnancy, a lady is more likely to experience this issue. This results from how the body builds immunity. During her first pregnancy, a mother's immune system learns how to develop defences against the red blood cells it detects as foreign. Sensitization to diverse types of red blood cells is how doctors describe the phenomena.

Detecting hemolytic anaemia

Frequently, the first step in identifying hemolytic anaemia is to review of medical history and present symptoms, doctor will perform a physical examination on body and check for pale or yellowed skin. They might also lightly push on different areas of tummy to feel for any tenderness that might indicate an enlarged liver or spleen.

This examination measures the amount of haemoglobin in the red blood cells that liver has broken down and digested. This test measures the amount of immature red blood cells that the body producing before they mature into adult red blood cells. One of the extra procedures is a urine examination to determine whether red blood cell breakdown is present. In some cases, a bone marrow aspiration or biopsy will be necessary. This test can reveal both the quantity and form of red blood cells generated.
