Low Iron Symptoms: When Should You Ask Your GP?

Feeling tired, weak, dizzy, or short of breath can be easy to blame on stress, poor sleep, or a busy routine. But sometimes, these symptoms may be linked to low iron levels.

Iron is important because it helps the body make haemoglobin, which carries oxygen in the blood. When iron levels are low, your body may not get the oxygen support it needs to function well.

Why low iron can be missed

Low iron can develop gradually. Some people may feel run down for weeks or months before realising something is not right. Others may only discover low iron after a blood test.

Symptoms can also overlap with many other conditions, such as thyroid problems, vitamin deficiencies, infections, stress, or poor sleep. This is why it is better not to assume the cause without medical advice.

Signs of low iron to watch for

You may want to speak with a GP if you notice:

• Ongoing tiredness
• Weakness or low energy
• Dizziness or light-headedness
• Shortness of breath
• Headaches
• Pale skin
• Fast or noticeable heartbeat
• Poor concentration
• Cold hands and feet
• Restless legs
• Heavy periods

These symptoms can have many possible causes, but they are worth checking if they are new, persistent, or affecting your daily life.

Who may be more at risk?

Low iron may be more common in people with heavy periods, pregnancy, certain bowel conditions, low iron intake, recent blood loss, or difficulty absorbing nutrients.

Some people may also be at risk if they follow restrictive diets or have ongoing digestive symptoms. A GP can help assess your personal risk and decide whether testing is needed.

What happens during an iron check?

A GP may ask about your symptoms, diet, periods, medical history, medications, and any signs of bleeding or digestive issues. Blood tests may be recommended to check iron levels, haemoglobin, and other possible causes of fatigue.

If your iron is low, your GP can discuss the likely cause and the most suitable treatment options.

Why finding the cause matters

Taking iron without understanding the reason for low levels may not be enough. In some cases, low iron may be linked to heavy bleeding, poor absorption, diet, or another health condition that needs attention.
