Anaemia is a condition that affects millions of people worldwide and can significantly impact patients’ quality of life. In this article, we explain what anaemia is, the different types of anaemia, and the treatments available.
What is anaemia, and why does it occur?
Anaemia is defined as a pronounced decrease in the number of red blood cells or the concentration of haemoglobin in healthy red blood cells. Red blood cells are responsible for transporting oxygen to tissues. A lower number of red blood cells can cause symptoms such as fatigue, weakness, and difficulty concentrating. Essentially, it’s as if our “oxygen transport system” doesn’t have enough vehicles to make all its deliveries.
Main types of anaemia
There are many types of anaemia, each with specific causes that require different treatment approaches. Below, we describe the main types:
- Iron-deficiency anaemia (due to lack of iron):
- The most common type of anaemia is usually caused by insufficient iron intake in the diet, excessive blood loss, or both.
- Common in women of childbearing age and pregnant women.
- Can develop gradually, meaning some symptoms may go unnoticed.
- Responds well to treatment with iron supplements.
- Haemolytic anaemia:
- In this type of anaemia, red blood cells are destroyed faster than the body can replace them.
- Can be hereditary or acquired.
- Requires specific diagnosis and treatment.
- Often presents with acute crises.
- Needs specialised monitoring to avoid complications.
- Sickle cell anaemia:
- A hereditary type of anaemia, meaning it is passed from parents to children.
- Red blood cells have an abnormal shape, making it challenging to function correctly and potentially causing circulation problems.
- Requires ongoing specialised medical care to prevent and treat complications.
- Can cause episodes of severe pain (painful crises) and needs a comprehensive care approach.
- Chronic anaemia:
- Long-term anaemia is often linked to other illnesses.
- Requires continuous monitoring as it can affect quality of life.
- Needs a comprehensive treatment addressing both the anaemia and underlying causes.
Specific at-risk groups
Below, we explain which population groups, due to their characteristics, may be at higher risk of developing anaemia and what measures can help maintain healthy haemoglobin levels.
- Pregnant women: During pregnancy, iron requirements increase to support both the mother and the growing baby. This is why prenatal monitoring and follow-up are essential. Low iron levels can increase the risk of complications for both mother and baby. Depending on each woman’s specific needs, the doctor may recommend starting preventive iron supplementation. In these cases, it’s essential to conduct regular iron level checks during pregnancy to prevent deficiencies.
- Athletes: People who engage in intense sports also have a higher risk of anaemia due to the extra iron demand generated by physical activity, especially in endurance sports. In these cases, it is recommended:
- Adapt nutritional needs to maintain good performance
- Evaluation and, if necessary, appropriate iron supplementation for each type of sport.
- Personalised monitoring by a healthcare professional to avoid anaemia risks and optimise performance.
- Older adults: With age, certain factors can increase the risk of anaemia in older adults, such as reduced iron absorption capacity. Additionally, they may be taking medications that can affect iron absorption or metabolism. Therefore, conducting regular checks and adapting treatments according to individual needs is advisable.
- Vegetarians and vegans: People following strict vegetarian or vegan diets may consume less haem iron, which is found mainly in animal products, and should pay special attention to their diet.
- Lower intake of haem iron.
- Need for dietary planning.
- Possible need for iron supplementation, especially in cases of low levels.
It’s advisable to conduct regular checks and receive nutritional advice to ensure adequate iron intake and prevent anaemia.
How is anaemia treated? Advanced treatment options
Current anaemia treatments include multiple options:
1.Conventional treatments:
- Oral iron supplements: Suitable for many patients with mild iron deficiency. Easy to administer but requires regular medical monitoring.
- Intravenous iron: Used for those who cannot tolerate oral iron or need rapid replenishment.
- Blood transfusions: Recommended in severe cases to quickly raise haemoglobin levels.
- Vitamin B12 and folic acid: Essential when anaemia is due to deficiencies in these vitamins.
- Erythropoietin: A hormone that stimulates red blood cell production, used in specific cases like chronic kidney disease-related anaemia.
2. New therapies:
Thanks to medical advances, there are now options beyond traditional treatments:
- Improved iron formulations with better absorption and fewer side effects.
- Biological treatments: Medications using modified human proteins to aid red blood cell production.
- Gene therapy: A promising option for genetic anaemias in certain patients.
- Personalised medicine: Treatments tailored to individual patient characteristics for better effectiveness and fewer side effects.
- Optimised protocols: Treatment plans combining different therapies.
3. Complementary treatments:
- Supervised herbal medicine
- Natural supplements
- Acupuncture
- Mindfulness for stress management
- Adapted exercise
Advanced diagnostic tests
Today, anaemia diagnosis relies on a combination of tests to understand its cause and find the right treatment. These tests include:
1. Basic tests:
- Full blood count (FBC): Measures red blood cell levels and quality.
- Serum iron levels: Key indicator of iron status.
- Ferritin: Measures iron stores.
- Vitamin B12: Essential for red blood cell production.
- Folic acid: Also crucial for red blood cell production.
2. Specialised tests: If basic tests are inconclusive, more advanced tests may be done, such as:
- Bone marrow study
- Genetic testing
- Inflammation markers
- Absorption studies
- Haemolysis markers
- Erythropoietin analysis
Myths and realities about anaemia
To better understand anaemia, it’s important to debunk common myths:
- Myth: “Only pale people have anaemia.”
Reality: Anaemia can affect anyone, regardless of appearance. It doesn’t always cause visible paleness.
- Myth: “Eating lots of spinach cures anaemia.”
Reality: While spinach contains iron, its content is limited. A varied diet—and often supplementation—is needed.
- Myth: “Only women get anaemia.”
Reality: Though more common in women, men can also develop anaemia, mainly due to certain illnesses or nutritional deficiencies.
- Myth: “All types of anaemia are treated the same.”
Reality: Each type requires specific treatment.
Potential complications if anaemia is left untreated
The consequences can be severe if you experience any of the symptoms mentioned earlier. Possible complications include:
1. Cardiovascular complications:
- Heart strain
- Arrhythmias
- Heart failure
- Angina
- Chronic fatigue
2. Neurological problems:
- Difficulty concentrating
- Frequent dizziness
- Headaches
- Sleep disturbances
- Irritability
3. Pregnancy complications:
- Risk of premature birth
- Low birth weight
- Foetal development issues
- Higher risk of C-section
- Slower postpartum recovery
