Key Information

Your Results: One of your recent blood tests has come back showing your iron level is a little lower than we would like it to be.

The Goal: This video explains exactly what being low in iron means, why it might be making you feel unwell, and our plan to get your levels back to normal.

What is Iron Deficiency?

Think of iron as the key ingredient your body uses to make haemoglobin.

The Role of Haemoglobin: This is a vital protein inside your red blood cells. Its job is to carry oxygen from your lungs to the rest of your body, providing you with energy.

The Problem: When you are low on iron, you cannot make enough haemoglobin. This means oxygen is not being delivered to your cells and organs as effectively as it should be.

The Symptoms: Without enough oxygen being delivered, it is very common to feel tired, breathless, and run down.

Your Treatment Plan

Our goal is to get your iron levels back to normal so your body can produce the haemoglobin it needs.

1. Your Prescription

The Medication: We have sent a prescription for iron tablets directly to your nominated pharmacy.
Duration: You will likely need to take these for at least 3 months.
Why so long?: This makes sure we not only correct your current low level but also build your body's iron stores back up for the future.

2. Top Tip for Absorption

Take your iron tablet with a source of Vitamin C, like a small glass of orange juice. This helps your body absorb the iron much more effectively.

Managing Side Effects

It is common to experience some side effects, especially when you first start taking iron.

Common Issues: You might notice some constipation, an upset stomach, or feeling a bit nauseous.
Dark Poo (Do Not Panic): You will almost certainly see your poo become a very dark, almost black colour. Please do not be alarmed by this; it is a completely normal and expected sign that the iron is making its way through your body.

How to Reduce Stomach Upset:

If you find the tablets are upsetting your stomach, try:

• Taking them with or shortly after food.
• Taking them every other day.

What Happens Next?

It is important to persevere with the treatment if you can. However, if you find the side effects too disruptive, or if you have any further questions, please let us know.

Discuss Your Iron Prescription
