What Is Anaemia and Why Should You Be Concerned?

The Link Between Anaemia and Parasites

Anaemia is a common but often overlooked condition that affects millions of people across the UK. While many associate it simply with “low iron,” the reality is more complex—and in some cases, even linked to parasitic infections.

What Is Anaemia?

Anaemia is a condition in which the blood has a reduced ability to carry oxygen around the body. This is usually due to a decrease in haemoglobin or red blood cells.

In simple terms:Anaemia = reduced oxygen delivery to tissues due to problems with red blood cells.

Common Symptoms of Anaemia

Anaemia can develop gradually and may go unnoticed at first. Common symptoms include:

• Persistent fatigue and low energy

• Shortness of breath

• Dizziness or lightheadedness

• Pale skin or yellowish tint

• Cold hands and feet

• Rapid or irregular heartbeat

• General weakness

In some cases, anaemia may be detected only through routine blood tests.

Main Causes of Anaemia

Anaemia is not a disease itself, but a sign of an underlying issue. The most common causes in the UK include:

Iron deficiency

The leading cause of anaemia, often linked to:

• Poor dietary intake

• Heavy menstrual bleeding

• Hidden internal bleeding (e.g. gastrointestinal)

Vitamin deficiencies

Lack of:

• Vitamin B12

• Folic acid (B9)

Chronic conditions

Such as:

• Kidney disease

• Autoimmune disorders

• Cancer

Blood loss

Including:

• Heavy periods

• Ulcers or internal bleeding

Bone marrow disorders

Where red blood cell production is impaired

Can Parasites Cause Anaemia?

Yes—parasites can contribute to anaemia, although this is less common in the UK compared to other parts of the world. However, it should not be overlooked, especially in certain situations.

1. Blood Loss Caused by Parasites

Some intestinal worms attach to the gut lining and feed on blood.

Example: hookwormsEffect: Chronic blood loss → iron deficiency anaemia

2. Destruction of Red Blood Cells

Certain parasites invade and destroy red blood cells.

Example: MalariaEffect: Haemolytic anaemia

3. Nutrient Depletion

Some parasites absorb essential nutrients needed for red blood cell production.

Example: fish tapewormEffect: Vitamin B12 deficiency → megaloblastic anaemia

4. Chronic Inflammation

Persistent infection can disrupt how the body uses iron.

Effect: Anaemia of chronic disease

5. Poor Nutrient Absorption

Damage to the gut lining can reduce absorption of:

• Iron

• Vitamin B12

• Folate

When Should You Consider Parasites?

In the UK, parasitic infections are relatively uncommon but may be relevant if you:

• Have unexplained or persistent anaemia

• Experience ongoing digestive symptoms

• Have travelled to tropical or high-risk regions

• Show abnormal blood results (e.g. eosinophilia)

Types of Anaemia

• Iron deficiency anaemia

• Vitamin deficiency anaemia

• Haemolytic anaemia

• Aplastic anaemia

• Anaemia of chronic disease

• Sickle cell anaemia

• Thalassaemia

Key Takeaway

Anaemia is not a diagnosis—it’s a warning sign.

Identifying the root cause is essential for effective treatment. While parasites can play a role, they are not the most common cause in the UK.
