Anemia: Recognising the Signs and Symptoms
Anaemia is a common yet often overlooked condition that affects millions worldwide, especially women and children. Defined as a deficiency in the number or quality of red blood cells (RBCs) or haemoglobin, anaemia leads to reduced oxygen flow to the body’s organs. While it may seem minor initially, untreated anaemia can result in severe health complications, reduced quality of life, and chronic fatigue.
Recognising the signs and understanding the causes of anaemia is crucial for early diagnosis and management. In this article, we’ll dive deep into its symptoms, risk factors, and effective treatment strategies to help you take charge of your health.
What Is Anaemia?
Anaemia occurs when your body lacks enough healthy red blood cells or haemoglobin to carry adequate oxygen to your tissues. It’s not a disease itself but a symptom of other health conditions, such as nutritional deficiencies, chronic diseases, or genetic disorders.
Haemoglobin, the oxygen-carrying protein in red blood cells, is essential for delivering oxygen throughout the body. When haemoglobin levels drop, organs and muscles receive less oxygen, leading to fatigue and other symptoms.
Common Types of Anaemia
There are several types of anaemia, each with different causes and treatments. The most common types include:
- Iron-deficiency anaemia: Caused by insufficient iron intake or absorption.
- Vitamin-deficiency anaemia: Due to low levels of vitamin B12 or folate.
- Aplastic anaemia: A rare condition where the body doesn’t produce enough blood cells.
- Haemolytic anaemia: Caused by premature destruction of red blood cells.
- Sickle cell anaemia: A genetic disorder resulting in abnormally shaped red blood cells.
Among these, iron-deficiency anaemia is the most prevalent, particularly among menstruating women, pregnant individuals, and those with poor diets.
Recognising the Symptoms of Anaemia
Symptoms of anaemia can vary depending on the severity and type, but the most common signs include:
- Fatigue and weakness: Feeling constantly tired or lacking energy is a hallmark symptom.
- Pale or yellowish skin: Decreased haemoglobin can result in a pale appearance.
- Shortness of breath: Even mild exertion may lead to breathlessness.
- Chest pain or palpitations: The heart must work harder to deliver oxygen.
- Dizziness or light-headedness: Especially noticeable when standing up suddenly.
- Cold hands and feet: Poor circulation due to inadequate red blood cells.
- Headaches: Caused by decreased oxygen to the brain.
- Brittle nails or hair loss: These may signal iron or nutrient deficiency.
- Cravings for non-food substances: Such as dirt, ice, or starch (a condition known as pica).
It’s important to note that many symptoms develop gradually, and some people may have anaemia without noticing any major signs until the condition worsens.
What Causes Anaemia?
Several underlying causes can lead to anaemia. The most common include:
- Blood loss: Heavy menstrual bleeding, internal bleeding (e.g., ulcers), or surgery.
- Nutrient deficiencies: Inadequate intake of iron, vitamin B12, or folic acid.
- Chronic diseases: Conditions like kidney disease, cancer, or inflammatory bowel disease.
- Genetic disorders: Such as sickle cell anaemia or thalassemia.
- Pregnancy: Increased blood volume during pregnancy can dilute haemoglobin levels.
- Infections or autoimmune diseases: These can interfere with red blood cell production.
Who Is at Risk?
While anaemia can affect anyone, certain groups are more susceptible:
- Women of childbearing age (due to menstruation)
- Pregnant and postpartum women
- Vegetarians and vegans (who may lack iron and B12)
- Infants and young children
- Elderly individuals
- People with chronic conditions such as kidney disease or cancer
Regular screenings and paying attention to subtle symptoms can help in early detection.
How Is Anaemia Diagnosed?
If your doctor suspects anaemia, they may perform the following tests:
- Complete blood count (CBC): Measures haemoglobin and red blood cell count.
- Iron studies: Includes serum ferritin, serum iron, and transferrin saturation.
- Vitamin B12 and folate levels: To check for deficiencies.
- Peripheral blood smear: Analyses the size and shape of red blood cells.
- Additional tests: May include stool tests for hidden bleeding or bone marrow biopsy in rare cases.
Accurate diagnosis is vital to determine the type of anaemia and tailor appropriate treatment.
Treatment Options for Anaemia
Treatment depends on the type and underlying cause of anaemia. Common interventions include:
1. Iron Supplements
For iron-deficiency anaemia, doctors often recommend oral iron tablets. In more severe cases, intravenous (IV) iron may be administered.
2. Dietary Changes
Include iron-rich foods such as red meat, spinach, legumes, and fortified cereals. Vitamin C enhances iron absorption, so pair iron sources with citrus fruits or bell peppers.
3. Vitamin B12 or Folic Acid
For anaemia caused by deficiencies, supplements or dietary adjustments may be needed. In cases of B12 malabsorption, injections may be prescribed.
4. Treating Underlying Conditions
If a chronic illness is contributing to anaemia, managing that condition is critical to resolving the anaemia.
5. Blood Transfusions
In cases of severe anaemia or significant blood loss, a transfusion may be necessary to quickly restore red blood cells.
6. Medications
Erythropoiesis-stimulating agents (ESAs) can help increase red blood cell production in people with kidney disease or undergoing chemotherapy.
How to Prevent Anaemia
Prevention strategies include:
- Eating a balanced diet rich in iron, B12, and folate
- Taking prenatal vitamins during pregnancy
- Addressing heavy menstrual bleeding with medical guidance
- Scheduling regular health check-ups
- Managing chronic diseases proactively
Early prevention not only reduces the risk of developing anaemia but also enhances overall vitality and immune function.
Living Well with Anaemia
Being diagnosed with anaemia doesn’t mean your life has to be limited. With proper diagnosis, lifestyle modifications, and treatment, many individuals lead full, active lives.
Monitor your energy levels, keep up with follow-up appointments, and advocate for your health. Don’t ignore persistent tiredness — it’s your body signalling the need for care.

FAQs
How do I know if I have anaemia?
Common symptoms include fatigue, pale skin, dizziness, and shortness of breath. A blood test is required for diagnosis.
What are the best foods for treating anaemia?
Iron-rich foods such as red meat, spinach, lentils, tofu, and fortified cereals, along with vitamin C-rich foods, are excellent choices.
Can anaemia go away on its own?
Mild cases may resolve with improved diet, but most require treatment or management of underlying conditions.
Is anaemia dangerous?
If left untreated, anaemia can lead to complications such as heart problems, extreme fatigue, or pregnancy issues.
How often should I get tested for anaemia?
If you're in a high-risk group (e.g. pregnant, heavy periods, or have chronic illness), your doctor may recommend regular screening every 6–12 months.
