Introduction

Imagine feeling exhausted after a full night's sleep, struggling to climb a flight of stairs, or watching skin turn pale for no apparent reason. For millions of people, this isn't an occasional bad day; it's everyday life. The culprit? anaemia.

Anaemia isn‘t simply about “low blood”; it affects the body‘s ability to transport oxygen throughout the body, to its brain, liver, heart, lungs and other organs and tissues. It affects women and men, adults and children, older people, and even the unborn. And yet it is one of the most treatable of conditions.

So, what is anaemia, what causes it, how is it diagnosed, and can it be prevented? Let's take a look.

What is Anaemia?

Anaemia is a condition in which individuals have insufficient healthy red blood cells or haemoglobin in their blood. Haemoglobin is a protein in red blood cells that transports oxygen. The body gets enough oxygen only if tissues receive enough.

The World Health Organisation (WHO) estimates that around 1.62 billion people, 24.8% of the global population, suffer from anaemia, with women of reproductive age and young children being the most susceptible groups.

What are the Functions of Blood Cells?

Red blood cells are the body's system for delivering oxygen. They are produced in the bone marrow and contain haemoglobin, which carries oxygen to the lungs. They then circulate through the body and deliver oxygen to every cell. They carry carbon dioxide back to the lungs for exhalation.

Healthy adults make approximately 2 million red blood cells every second. If individuals lose the ability to make blood cells, or red blood cells are destroyed faster than they are produced, anaemia occurs.

Types and Causes of Anaemia

The causes of anaemia vary widely depending on the type. There are over 400 types of anaemia; however, the majority of them can be grouped into three broad groups:

• Anaemia caused by blood loss (for example, heavy periods or gastrointestinal bleeding).

• Anaemia caused by absent or diminished red blood cell production (e.g, iron deficiency, vitamin B12 deficiency)

• Anaemia caused by the destruction of red blood cells (e.g. Sickle cell anaemia, haemolytic anaemia).

What are the Signs & Symptoms of Anaemia?

Anaemia symptoms may be very subtle or quite pronounced and debilitating. Typical symptoms are:

• Continuous fatigue and weakness

• Pale or yellowish complexion

• Shortness of breath, especially during exertion

• Dizziness or feeling faint.

• Irregular/fast heartbeat (palpitations)

• Cold hands and feet

• Headaches and problems concentrating

• Chest pain (most severe cases)

Note: Mild anaemia may go completely unnoticed, and individuals may not experience any symptoms at all; this is why controls are so important, particularly in high-risk groups.

What is the diagnosis of anaemia?

The diagnosis of anaemia is usually based on a good history and physical examination and requires blood tests. The main test performed is a CBC (Complete Blood Count), which measures:

• Haemoglobin/Hematocrit

• The number and dimensions of the red blood cells (MCV, MCH)

• Reticulocyte count (young red blood cells)

• White blood cell count and platelet count

Further tests (e.g., serum ferritin levels, vitamin B12 levels, a peripheral blood smear, a bone marrow biopsy, or genetic testing) may be indicated depending on the suspected classification of the anaemia.

What are the risk factors for anaemia?

Certain groups are more susceptible to anaemia. Key risk factors include:

• Women of childbearing age (loss from menstrual bleeding)

• Pregnant women (higher iron and folate requirements)

• Infants and young children (fast growth increases the need for nutrition)

• People over 65 years of age

• Vegetarians and vegans (less dietary iron and B12)

• People with chronic disease (kidney disease, cancer, diabetes)

• Family history of inherited anaemia, such as sickle cell or thalassemia

53% of women aged 15-49 years in India are anaemic, which is one of the highest rates of anaemia in the world.

What Are The Possible Complications?

If left untreated, anaemia can lead to serious health complications:

• Fatigue is so severe that it affects everyday function and lifestyle.

• Anaemia makes the heart work harder to circulate blood around the body, increasing the risk of arrhythmia and CHF.

• Pregnancy complications such as premature birth and low birth weight

• Organ damage resulting from sustained oxygen deficiency

• Reduced defences against bacterial, viral, and parasitic infections.

What Is The Treatment For Anaemia?

Anaemia treatment is entirely dependent on the cause. The more commonly used forms of treatment are:

• Iron supplementation (oral or intravenous) for iron-deficiency anaemia

• Vitamin B12 injections or oral supplements for pernicious anaemia

• Folic acid supplements for folate-deficiency anaemia

• Blood transfusions for severe or acute cases

• Bone marrow transplant for aplastic anaemia

• Medications to stimulate red blood cell production (e.g., erythropoiesis-stimulating agents)

• Managing the underlying chronic disease in anaemia

• Hydroxyurea and other targeted therapies for sickle cell anaemia

Disclaimer: Always follow the doctor's guidance. Overusing iron supplements without a deficiency can be toxic.

How Can We Prevent Anaemia?

While not all types of anaemia are preventable (especially genetic forms), nutritional anaemias, which are the most common, can largely be avoided with lifestyle changes:

• Eat iron-rich foods: red meat, leafy greens (spinach and kale), lentils, beans, tofu, fortified cereals

• Boost iron absorption by pairing iron-rich foods with vitamin C (citrus fruits, bell peppers)

• Avoid tea and coffee during meals

• Include vitamin B12 sources: eggs, dairy, meat, or B12-fortified foods

• Consider prenatal vitamins if you are pregnant or planning to conceive

• Get regular blood tests, especially if you fall into a high-risk category

• Treat any underlying medical conditions that may contribute to anaemia

When To See A Doctor?

See a doctor if feeling exhausted for a long time or if any of the above symptoms cannot be explained. If individuals have chest pain, severe breathlessness, or fainting, an ambulance should be called. Don‘t diagnose and treat yourself. The treatment of anaemias will be entirely dependent on the cause. Wrong supplements could actually be damaging. Reach out to the doctor for a further course of action.

Conclusion

Anaemia isn't simply being low on energy; it's an indicator that the body is signalling that something crucial requires attention. Delays in identifying the causes of nutritional deficiencies, chronic illnesses, or genetic factors can lead to long-term health issues. With effective treatment for anaemia and the right diets to prevent it, the vast majority of people can recover from or cope with it. If experiencing any of the above-mentioned symptoms, don‘t delay and go for an anaemia diagnosis.
