Hemolytic Anemia – How It Manifests in Adults and Children, and How It’s Treated?
Anemia has several forms and generally does not cause much concern, as we tend to believe that food supplements can help us correct associated deficiencies. However, these methods are not always effective. Why? Because each type of anemia has specific characteristics, which means that the body’s needs also vary. An example of anemia that requires special attention is hemolytic anemia, which involves the premature destruction of red blood cells.
What is hemolytic anemia? It is a disease in which red blood cells or erythrocytes are destroyed faster than they are produced through a process called hemolysis. Simply put, the number of these cells is lower than what the body needs to receive the required oxygen.
Who can suffer from hemolytic anemia and what are its causes? The disease affects both children and adults, and the triggering reasons are also diverse. Therefore, this article explores this topic in detail and analyzes the main causes.
Hemolytic Anemia – What It Is, Its Causes, and Symptoms
From a medical point of view, the definition of hemolytic anemia is a condition in which red blood cells or erythrocytes are destroyed faster than they are produced by the bone marrow. A low number of these cells in the blood leads to a reduced amount of oxygen reaching the lungs and the rest of the body. This hinders essential chemical processes at the cellular level. To understand how the disease works, we need to know that the lifespan of a red blood cell is 120 days. When it dies sooner, this type of anemia can set in.
Most of the time, when we say anemia, we think of iron-deficiency anemia, which is the most common type of the condition. For the latter, supplements can help alleviate symptoms. They can also be helpful in other forms of the disease, including hemolytic anemia.
One of the recommended supplements is Red Beet Juice ECO, a product made from organic beets, rich in vitamins, minerals, amino acids, and antioxidants. Its benefits are numerous, helping heart, brain, and liver health. It is also one of the best plants for the blood system. Regular consumption of beets helps purify the blood, prevent fat deposits on the walls of blood vessels, and reduce the risk of clot formation, contributing to healthy blood circulation.

Regarding anemia, red beet consumption helps replenish iron, vitamin B6, and magnesium reserves, deficiencies of the first two being often associated with this disease. Together, they stimulate the erythrocyte formation process.
Causes of Hemolytic Anemia
Why does hemolytic anemia occur? The disease is caused by several factors and is of two types: hereditary and acquired. These, in turn, are divided according to various causes and severity.
The main causes of hemolytic anemia include:
- certain viral or bacterial infections that trigger the destruction of red blood cells;
- autoimmune diseases, in which the immune system attacks red blood cells;
- hereditary conditions, which can trigger hemolytic anemia such as congenital spherocytosis or thalassemia;
- blood diseases such as leukemia, lymphoma, or myeloma;
- external factors, such as exposure to certain substances or even the use of medications that destroy red blood cells.
Unfortunately, hemolytic anemia can affect both children and adults. How do we know if we have this disease? In the absence of blood tests, specifically a complete blood count indicating a decrease in the number of erythrocytes, we can rely on physical symptoms.
Hemolytic Anemia – General Symptoms
Most of the time, the symptoms of hemolytic anemia are easier to observe in adults and can include:
- fatigue;
- weakness;
- pallor and/or jaundice;
- shortness of breath both during exertion and at rest;
- palpitations;
- darkening of the urine;
- fever in the absence of other conditions;
- abdominal pain.
In addition to these, there are other signs of the disease that can be detected through certain investigations. For example, an ultrasound can reveal an enlarged spleen or splenomegaly.
Besides these generalized signs, depending on age and health status, there may be others. What we also need to remember is that, in some cases, the symptoms are common to several types of anemia.
Autoimmune Hemolytic Anemia, Idiopathic, and Other Types
Hemolytic anemia can be divided into several categories, which in turn have multiple types. Depending on the manifestations, it can be mild, moderate, or severe.
The most important way to group the types of the disease is by the triggering cause and duration. Thus, hemolytic anemia can be:
- autoimmune;
- hereditary;
- idiopathic;
- regenerative.
Autoimmune Hemolytic Anemia
Autoimmune hemolytic anemia is when our immune system attacks its own red blood cells, causing hemolysis. This is one of the severe forms of the disease, requiring specialized medical care. Even its symptoms can be quite severe.
Among the causes that trigger autoimmune hemolytic anemia are:
- congenital diseases such as sickle cell disease, where red blood cells have a sickle shape;
- the use of certain medications that cause an aggressive immune system response.
The first step in treating this type of hemolytic anemia is a set of blood tests, where a complete blood count can guide the doctor towards a correct diagnosis.
Hereditary Hemolytic Anemia
Congenital hemolytic anemia, also known as hereditary anemia, is transmitted from parents to children through genetic mutations. Because of these genetic defects, parents can pass this form of anemia to their children.
Hereditary hemolytic anemia has several forms, each with its own mechanisms of manifestation. Among the most common types are:
Sickle Cell Anemia, a disease that affects hemoglobin, causing red blood cells to take on a sickle or crescent shape. These erythrocytes can obstruct blood vessels, leading to reduced blood flow.
Thalassemia is an inherited form of anemia. It is part of a group of conditions in which one of the protein chains that make up hemoglobin is either missing or produced in insufficient quantities. Thalassemia affects the blood’s ability to efficiently transport oxygen to cells.
Erythrocytic Enzyme Deficiencies represent another form of hereditary hemolytic anemia, caused by defects in the enzymes involved in red blood cell metabolism. In most cases, glucose-6-phosphate dehydrogenase (G6PD) deficiency is passed down from parents to children.
Hereditary Spherocytosis is another type of hemolytic anemia in which red blood cells take on a spherical shape. These are often destroyed in the spleen, so an enlarged spleen can be a sign of the disease.
Idiopathic Hemolytic Anemia
As the name suggests, this type of hemolytic anemia has no known causes. In most cases, external factors are the cause. Among these are worth mentioning:
- various infections, including viral and bacterial infections that trigger an immune system response;
- exposure to certain toxins, including household ones like naphthalene, as well as industrial ones like aniline, arsenic hydride, and nitrobenzene;
- bites from certain insects or reptiles, such as spiders or snakes;
- insect stings, especially from wasps;
- exposure to certain toxic plants, such as mushrooms.
In addition to these, certain medications can also lead to hemolytic anemia of unknown cause.
Regenerative Hemolytic Anemia
The regenerative form of the disease is caused by hemoglobin loss through hemorrhage or hemolysis. The differences between the two processes are that:
- in hemorrhage, erythrocytes exit the bloodstream, as is the case with cuts or wounds;
- in hemolysis, red blood cells are destroyed before they reach maturity.
Regenerative hemolytic anemia is also of several types. Specifically, it can be acute, chronic, internal, or external. Among the causes underlying it are:
- trauma;
- certain pathogens;
- ulcerations;
- neoplasms.
In most cases, regenerative hemolytic anemia occurs after erythrocyte formation, and chronic anemia is the most severe because it eliminates iron from the body.
Who can suffer from hemolytic anemia considering all its types? This condition can occur in both adults and children, including infants and pregnant women, affecting people of all age groups.
Hemolytic Anemia in Children and Adults
Hemolytic anemia can affect people of all ages, from infants to the elderly, depending on the factors triggering the disease.
In the early stages, the condition is often asymptomatic, and only a blood count can indicate the existence of a problem. The exception are those who already know they suffer from a type of hemolytic anemia, being aware that they can transmit it genetically.
Hemolytic Anemia in Children
In most cases, hemolytic anemia in infants and children is inherited. Thus, they can suffer from the hereditary form of the disease. The most common types are thalassemia and sickle cell anemia.
Hemolytic anemia in older children can also occur as a result of viral infections. It is important to note that this condition often remains undiagnosed in children, being discovered only in adulthood.
Hemolytic Anemia in Pregnancy and Newborns
A special case of hemolytic anemia is encountered in newborns, caused by Rh incompatibility between the mother and the fetus. This occurs when the mother has Rh-negative and the father Rh-positive, which can cause the baby to inherit the father’s Rh factor. In this context, the mother’s immune system can identify the fetus’s cells as foreign and attack them. Problems usually arise during the second pregnancy, when the mother’s immune response is stronger. The good news is that this form of hemolytic anemia can be prevented during pregnancy by administering specific medications that prevent immune conflict.
Hemolytic Anemia in Adults
Hemolytic anemia often manifests in adulthood, and fatigue, physical trauma, exposure to certain chemicals or medications can trigger the symptoms of this condition.
Symptoms experienced by adults who develop hemolytic anemia can include fatigue, confusion, dizziness, and even physical weakness. These are signs that should lead us to seek medical consultation and a series of blood tests, including a complete blood count.
Hemolytic Anemia – Diagnosis and Treatment
Diagnosing hemolytic anemia in children can be difficult because the disease tends to manifest later. In contrast, adults may present symptoms that prompt them to consult their family doctor or a general practitioner. They will analyze the patient’s medical history and, based on it, may recommend further investigations:
- complete blood count;
- other blood tests such as biochemical analyses;
- tumor marker tests;
- measurement of iron in the blood;
- measurement of C-reactive protein and ESR;
- urinalysis, to check for hemoglobin and iron;
- abdominal ultrasound, which can indicate an enlarged spleen.
In certain cases, a bone marrow biopsy may also be performed, given that red blood cells are formed there. If these tests show that we have anemia, other tests will be performed to determine the type and severity.
Treatment of Hemolytic Anemia
In mild cases of hemolytic anemia, treatment may not be necessary. However, in moderate and severe cases, the following may be performed:
- blood transfusions;
- surgery to remove the spleen, aimed at preventing erythrocyte destruction;
- bone marrow transplant to replace diseased cells, such as sickle cells.
Regarding medication, the doctor may prescribe:
- anticoagulants;
- monoclonal antibodies and immunosuppressants;
- steroid medications.
Iron, vitamin B12, and folic acid supplements may also be recommended.
Diet will also play an important role in improving the discomfort caused by hemolytic anemia. Among the most recommended foods are lean meat, cereals, and green leafy vegetables.
In conclusion, hemolytic anemia involves the premature destruction of red blood cells, affecting both children and adults, including newborns. It can be caused by autoimmune diseases, infections, exposure to toxic substances, or certain medications, but it can also be hereditary. Symptoms include fatigue, pallor, dizziness, fever, and tachycardia, and an enlarged spleen is a common sign. Diagnosis is made through blood tests, and treatment may include transfusions, medications, spleen removal, or bone marrow transplantation. A proper diet and supplements of iron, vitamin B12, and folic acid can help manage the disease.
