Anaemia
Anaemia is a medical condition that occurs when a person has a low number of red blood cells or a low amount of haemoglobin in their blood. Haemoglobin is a protein in red blood cells that carries oxygen from the lungs to the body’s tissues. Symptoms of anaemia can include weakness, fatigue, shortness of breath, pale skin, and cold hands and feet. Causes of anaemia can include a lack of iron, vitamin B12, or folic acid in the diet, chronic diseases such as kidney disease or cancer, menstruation, genetic disorders, or blood loss from an injury. Treatment can vary depending on the cause, but may include iron supplements, dietary changes, medications, or blood transfusions.
Different types of anaemia
Anaemia is a medical condition that occurs when the body does not have enough red blood cells or haemoglobin. There are several anaemia types, each with their own causes and symptoms. Here are some of the most common types of anaemia:
- Iron-deficiency anaemia: This is the most common type of anaemia and occurs when the body doesn’t have enough iron to produce haemoglobin. Iron is necessary to make red blood cells. Symptoms may include weakness, fatigue, and pale skin.
- Vitamin deficiency anaemia: This type of anaemia occurs when the body doesn’t have enough vitamins necessary for red blood cell production. The most common vitamin deficiencies are vitamins B12 and folate. Symptoms may include weakness, shortness of breath and fatigue.
- Chronic disease: This type of anaemia occurs in people with chronic diseases such as cancer, HIV/AIDS, and rheumatoid arthritis. The immune system response to the disease can interfere with red blood cell production. Symptoms may include weakness, shortness of breath, and fatigue.
- Haemolytic anaemia: This type of anaemia occurs when the body destroys red blood cells faster than it can produce them. The condition can occur due to genetic conditions, infections, or autoimmune disorders. Symptoms may include jaundice, fatigue, and an enlarged spleen.
- Aplastic anaemia: This type of anaemia occurs when the bone marrow doesn’t produce enough red blood cells. It can be caused by medications, radiation, or toxins. Symptoms may include weakness, fatigue, and increased risk of infection.
It’s important to note that symptoms of anaemia can vary depending on the type of anaemia and the severity of the condition. If one suspects having anaemia, it’s important to speak with your doctor for proper diagnosis and treatment.
Causes of anaemia
Anaemia can be caused by various factors, including:
- Mineral deficiency: The most common cause of anaemia is iron deficiency, which can occur due to insufficient iron intake, poor absorption of iron from the diet, chronic blood loss, or increased iron requirements.
- Vitamin deficiency: Vitamin B12 and folate are essential for the production of red blood cells. Deficiencies in these vitamins can lead to anaemia.
- Chronic kidney disease: Kidneys produce erythropoietin, a hormone that stimulates the production of red blood cells. In chronic kidney disease, erythropoietin production decreases, leading to anaemia.
- Chronic inflammation: Chronic inflammation can interfere with the production of red blood cells and cause anaemia.
- Genetic disorders: Certain genetic disorders, such as sickle cell anaemia and thalassemia, can cause anaemia.
- Blood loss: Acute or chronic blood loss from injuries, surgery, or menstruation can cause anaemia.
- Chronic diseases: Chronic diseases, such as cancer, HIV/AIDS, and autoimmune diseases, can cause anaemia.
- Medications: Certain medications, such as chemotherapy drugs, can cause anaemia as a side effect.
Overall, the causes of anaemia are diverse and can range from dietary deficiencies to chronic diseases. It is important to identify the underlying anaemia types and causes to ensure appropriate treatment.
Symptoms of anaemia
Anaemia is characterised by a wide range of symptoms that can vary in severity depending on the underlying cause and the individual’s overall health. Here are some common symptoms of anaemia:
- Fatigue and weakness
- Shortness of breath
- Rapid heartbeat or palpitations
- Dizziness or light-headedness
- Pale skin or mucous membranes
- Headaches or migraines
- Cold hands and feet
- Chest pain or angina
- Irregular menstrual periods
- Pica (craving non-food items)
If one is experiencing any of these symptoms, it is important to consult with a doctor for timely diagnosis.
Possible complications of anaemia
Anaemia can lead to a variety of complications if left untreated, including:
- Fatigue: Anaemia can cause a lack of energy and fatigue due to the body not receiving enough oxygen.
- Cardiovascular problems: Anaemia can cause the heart to work harder to pump oxygen-rich blood to the body’s tissues. This can lead to an increased risk of heart attack, heart failure, and stroke.
- Cognitive impairment: Anaemia can reduce the amount of oxygen reaching the brain, leading to problems with memory, concentration, and other cognitive functions.
- Complications during pregnancy: Anaemia during pregnancy can lead to low birth weight, premature birth, and other complications.
- Infections: Anaemia can weaken the immune system, making it easier to contract infections.
- Delayed wound healing: Anaemia can slow down the healing process of wounds due to the reduced oxygen supply to the affected area.
- Arrhythmia: Anaemia can cause an irregular heartbeat, which can lead to more severe cardiovascular complications.
- Developmental delays in children: Anaemia in children can lead to developmental delays and problems with growth.
Diagnosis of anaemia
Anaemia is a condition in which there is a decrease in the number of red blood cells or haemoglobin (the protein that carries oxygen) in the blood. It can cause weakness, fatigue, shortness of breath, pale skin, dizziness, and other symptoms.
There are several ways to diagnose anaemia. One common test is a complete blood count (CBC), which measures the number of red blood cells, haemoglobin, and other blood components. If the CBC shows low levels of red blood cells or haemoglobin, further testing may be needed to determine the underlying cause of the anaemia.
Additional tests that may be performed include iron studies to evaluate iron levels in the blood, a reticulocyte count to measure the number of young red blood cells in the blood, and a peripheral blood smear to examine the appearance of red blood cells under a microscope. Depending on the results of these tests, further testing may be necessary to determine the specific cause of the anaemia.
Diet to be followed
Anaemia is a condition characterised by a lack of sufficient healthy red blood cells in the body. Proper nutrition plays a key role in the prevention and treatment of anaemia.
Here are some dietary recommendations to follow for anaemia:
- Iron: Increase iron-rich foods such as fish, red meat, beans, poultry, tofu, lentils, dark leafy greens, and fortified cereals.
- Vitamin C: Consume vitamin C-rich foods, such as citrus fruits, tomatoes, and peppers, which helps to improve the absorption of iron from plant-based sources.
- Vit B12: Include foods high in vitamin B12, such as beef, poultry, fish, dairy products and eggs, or consume cereals and plant-based milk.
- Folate: Incorporate foods rich in folate, such as spinach, asparagus, beans, and fortified cereals.
- Supplements: One can consider taking supplements, after consulting your doctor, especially if they have difficulty meeting their nutrient needs through diet alone.
- Consultation: Talking to your doctor for individualised advice on the best dietary approach for specific type of anaemia.
Avoid
- Avoid tea and coffee with meals, as they can inhibit the absorption of iron.
One must remember that a balanced and varied diet, rich in nutrient-dense whole foods, is key to supporting overall health and preventing nutrient deficiencies, including anaemia.
Risk factors
Anaemia is a condition where the body lacks enough red blood cells or haemoglobin, which can lead to shortness of breath, fatigue, and weakness. The following are some of the risk factors associated with anaemia:
- Iron deficiency: The most common cause of anaemia is iron deficiency. This occurs when the body lacks sufficient iron to produce haemoglobin.
- Poor diet: A diet low in iron, vitamin B12, and folate can lead to anaemia.
- Blood loss: Chronic blood loss from heavy menstrual periods, gastrointestinal bleeding, or frequent blood donation can lead to anaemia.
- Pregnancy: During pregnancy, the body requires more iron to support the growth of the foetus, and pregnant women may become anaemic if their iron intake is insufficient.
- Chronic diseases: Certain chronic diseases like kidney disease, cancer, HIV/AIDS, and rheumatoid arthritis can increase the risk of anaemia.
- Genetics: Certain genetic conditions like sickle cell anaemia and thalassemia can increase the risk of anaemia.
- Medications: Certain medications like chemotherapy drugs, anticoagulants, and anticonvulsants can lead to anaemia.
- Age: Anaemia is more common in older adults due to decreased production of red blood cells and chronic diseases.
It is important to identify and manage the underlying cause of anaemia to prevent complications and improve quality of life.
Lab tests for anaemia diagnosis
The diagnosis of anaemia typically involves several laboratory tests. Here are the most commonly used lab tests for anaemia diagnosis:
- Complete blood count (CBC): A CBC is a test that measures the number of red blood cells, white blood cells, and platelets in the blood. It also measures the haemoglobin and hematocrit levels. Low haemoglobin and hematocrit levels indicate anaemia.
- Reticulocyte count: A reticulocyte count measures the number of young red blood cells in the blood. An increased reticulocyte count indicates that the body is producing more red blood cells to compensate for anaemia.
- Iron studies: Iron studies measure the levels of iron in the blood, including serum iron, ferritin, and transferrin saturation. Low iron levels indicate iron deficiency anaemia.
- Vitamin B12 and folate levels: Vitamin B12 and folate are necessary for the production of red blood cells. Low levels of these vitamins can cause anaemia.
- Peripheral blood smear: A peripheral blood smear is a microscopic examination of a blood sample. It can identify the shape and size of red blood cells and can help diagnose specific anaemia types, such as sickle cell anaemia.
It is important to note that additional tests may be necessary to determine the underlying cause of anaemia, such as a bone marrow biopsy or genetic testing.
Treatment for anaemia
The treatment for anaemia depends on the underlying cause and severity of the condition. Here are some possible treatment options:
- Dietary changes: Eating a diet rich in iron, vitamin B12, and folic acid can help prevent anaemia. Whole foods such as leafy green vegetables, sprouts, beans, and fortified cereals are good sources of these nutrients and easily absorbed in the blood.
- Iron supplementation: Iron is a key component of haemoglobin, and iron deficiency is a common cause of anaemia. Iron supplements can be taken orally or intravenously, depending on the severity of the anaemia.
- Vitamin B12 supplementation: Vitamin B12 is necessary for the production of red blood cells. If anaemia is caused by a deficiency of this vitamin, B12 supplements can be given orally or by injection.
- Folic acid supplementation: Folic acid is another nutrient necessary for the production of red blood cells. If anaemia is caused by a deficiency of this nutrient, folic acid supplements can be taken orally.
- Blood transfusion: In severe cases of anaemia, a blood transfusion may be necessary to quickly increase the number of red blood cells in the body.
- Treatment of underlying conditions: Anaemia can be a symptom of an underlying medical condition, such as kidney disease or cancer. Treating the underlying condition can help alleviate anaemia.
It is important to seek medical advice if one suspects having anaemia or any related symptoms.

Types of Anaemia FAQs:
How many classification types of anaemia chart are there?
Anaemia is a medical condition in which the body does not have enough red blood cells or haemoglobin to carry oxygen to the body's tissues. There are several anaemia types, each with different causes and characteristics.
1. Iron-deficiency anaemia: The most common type of anaemia, caused by a lack of iron in the body, leading to insufficient production of haemoglobin. There are various types of iron deficiency anaemia as well.
2. Vitamin-deficiency anaemia: Caused by a lack of essential vitamins such as vitamin B12 or folate, which are necessary for the production of healthy red blood cells.
3. Haemolytic anaemia: Occurs when red blood cells are destroyed faster than they can be produced, leading to a shortage of these cells in the body.
4. Sickle cell anaemia: An inherited form of anaemia in which red blood cells become misshapen and break down, leading to a shortage of these cells in the body.
5. Aplastic anaemia: Caused by damage to the bone marrow, which reduces the production of red blood cells, white blood cells, and platelets.
6. Thalassemia: An inherited blood disorder that results in reduced production of haemoglobin and red blood cells.
7. Pernicious anaemia: Caused by a deficiency in vitamin B12, which leads to the body's inability to produce enough healthy red blood cells.
What is the most common type of anaemia?
The most common type of anaemia worldwide is iron deficiency anaemia. Iron is a mineral essential for the production of haemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. When the body does not have enough iron to produce haemoglobin, it leads to a decrease in the number of red blood cells, resulting in anaemia.
Iron deficiency anaemia can be caused by a variety of factors, including a lack of dietary iron, chronic blood loss (such as from heavy menstrual periods or gastrointestinal bleeding), or an inability to absorb iron properly. Symptoms of iron deficiency anaemia can include weakness, shortness of breath, headache, fatigue and pale skin.
Which anaemia is common in females?
Iron-deficiency anaemia is the most common type of anaemia in females, especially in those of childbearing age. This occurs when there is a shortage of iron in the body, leading to a decreased production of red blood cells and a decrease in haemoglobin levels. The causes of iron-deficiency anaemia in females can include heavy menstrual bleeding, pregnancy, and inadequate iron intake in the diet. Treatment typically involves increasing iron intake through diet or supplements and addressing the underlying cause, such as managing heavy menstrual bleeding or treating iron-deficiency during pregnancy.
Are all types of anaemia curable?
Not all types of anaemia are curable, as the treatment and prognosis depend on the underlying cause. For instance, anaemia caused by iron deficiency can usually be cured through iron supplementation and dietary changes. Similarly, anaemia due to vitamin deficiency can be treated with supplements. However, anaemia caused by chronic conditions such as kidney disease or cancer may require ongoing management and treatment of the underlying condition. In some cases, anaemia may be a symptom of a more serious condition that requires extensive medical intervention. Therefore, it is essential to consult a doctor for a proper diagnosis and treatment plan.
