How Donating Blood Can Support Your Liver Health
Donating blood saves lives. For some, it also helps manage specific liver health conditions. While blood donation doesn’t typically test liver function, it plays an important role for people with haemochromatosis — a condition where your body stores too much iron, which can damage your liver over time.
What is haemochromatosis and how does it affect liver health?
Haemochromatosis is a genetic condition that causes your body to absorb and store too much iron. This extra iron builds up in your organs, especially your liver, which can lead to inflammation and scarring. Left untreated, it may cause serious problems like cirrhosis or liver failure.
Iron overload develops slowly and often without symptoms, so catching it early helps prevent lasting damage. You might feel unusually tired, have joint pain, or notice your skin darkening but these signs can be easy to miss.
Other early symptoms can include abdominal discomfort or irregular heartbeat. Risk factors for haemochromatosis include family history, being over 40, and Northern European descent.
If you notice these symptoms or have risk factors, consider talking to your GP about screening.
How does blood donation help people with haemochromatosis?
People with haemochromatosis benefit from therapeutic phlebotomy — regular blood removal. This process lowers iron levels, protects the liver, and reduces risks.
Your healthcare team will work with you to decide how often you need to donate, keeping you safe.
How is therapeutic phlebotomy different from regular blood donation?
It’s important to know the difference.
Routine blood donation is a voluntary act to help others. Donors undergo health checks to make sure donating is safe for themselves and the people receiving their blood.
Therapeutic phlebotomy is a medical treatment prescribed to manage iron overload. The amount and frequency of blood taken are carefully planned by your doctor.
Understanding this difference helps you see the specific liver health benefits linked to blood donation.
Does blood donation check liver health?
Donation centres test for infections like hepatitis B and C. They check haemoglobin and iron levels to make sure donors are healthy enough.
However, liver enzymes such as ALT and AST are not tested during donation. These require medical tests ordered by your GP.
How can you get a clearer picture of your liver health?
If you’re worried about your liver or managing haemochromatosis, your GP may order:
- Blood tests that measure liver function
- Genetic tests for haemochromatosis mutations
- A FibroScan—a painless scan that measures liver stiffness and fat
You can use apps like the MyLife365.Me lifestyle app to track your lifestyle habits and monitor any changes in your behaviour helping you to manage your meals and health.

Why is liver so important for general health?
Your liver filters toxins, processes nutrients, and stores vitamins. Damage builds quietly over time, so awareness matters.
Other common liver diseases, such as fatty liver disease and hepatitis, benefit from early detection and healthy habits.
Excess iron from haemochromatosis can also affect your heart, pancreas, joints, and skin. Managing iron overload through blood donation helps protect these organs too.

Who should avoid donating blood?

How often can you donate blood?
Men usually donate every 12 weeks. Women every 16 weeks. Those with haemochromatosis follow medical advice.
What to expect when donating blood
Donation centres prioritise your safety with health questionnaires and checks. The process is straightforward and usually well tolerated. You can pause or stop if needed.
