Iron deficiency anaemia is very common, and there are several possible reasons why it develops. Understanding the underlying cause is the first step towards effective treatment and long-term wellbeing.

• Blood loss: heavy periods are a common cause in women; blood loss from the digestive system can affect anyone
• Poor absorption: conditions like coeliac disease can reduce iron uptake in the small intestine
• Low dietary intake: uncommon in developed countries, but possible if intake is very limited

Gastrointestinal bleeding and anaemia

Bleeding in the digestive tract can be obvious or hidden. Possible causes include:

• Colitis (Crohn’s disease or ulcerative colitis)

• Bowel cancer

• Angiodysplasia (fragile blood vessels in the bowel)

Iron deficiency anaemia can sometimes develop quietly, but when symptoms do appear they’re often easy to recognise. Knowing what to look out for can help you get the right support and treatment quickly. Symptoms include:

• Fatigue, lethargy, or breathlessness on exertion
• Pale complexion
• Smooth tongue, brittle or ridged nails, or mouth sores (rare)
• Blood in stools if linked with GI bleeding

At The Physicians’ Clinic we can carry out all the investigations you’ll need, and we’ll guide you step by step through the process (below) to find the cause and provide the right treatment for you:

• Detailed medical history, including diet and (for women) periods
• Assessment for visible or hidden blood loss
• Investigations, which may include gastroscopy, colonoscopy and sometimes video capsule endoscopy

Once we’ve identified the cause, we can tailor your treatment to your unique needs. This may involve dietary advice, iron supplements, antibiotics (if linked to infection), or treatment of an underlying condition.

With leading experts in the investigation and management of iron deficiency anaemia on our team, we can support you with clear answers and effective treatment.
