Hemochromatosis: How Iron Overload Damages Your Liver and How Phlebotomy Saves Lives

Imagine feeling tired all the time, your joints ache for no reason, and you’ve lost interest in sex. You go to the doctor, get blood tests, and they tell you it’s stress or aging. But what if it’s something deeper-something your body can’t get rid of? That’s hemochromatosis. It’s not just high iron. It’s your body absorbing too much iron from food, and over years, that iron piles up in your liver, heart, and pancreas like rust in a pipe. Left untreated, it can lead to cirrhosis, diabetes, or even liver cancer. The good news? There’s a simple, proven fix: phlebotomy.

What Exactly Is Hemochromatosis?

Hemochromatosis is a genetic disorder where your body absorbs way more iron than it needs. You eat a steak, your gut says, “More, please,” and it keeps pulling iron into your bloodstream-even when you’re full. Normally, your liver makes a hormone called hepcidin to shut off iron absorption when levels are high. In hemochromatosis, that signal breaks. The result? Iron builds up slowly, silently, over decades.

This isn’t rare. In people of Northern European descent-especially those with Irish, Scottish, or Welsh roots-one in every 200 carries two copies of the faulty HFE gene (C282Y homozygous). That’s about 1 million people in the U.S. alone. And most don’t know it. Only 10 to 15% of those with the gene mutation are diagnosed. Why? Because symptoms show up late. And they look like everything else.

How Iron Turns Into a Silent Killer

Iron isn’t bad. Your blood needs it. But when it’s stuck in the wrong places, it turns toxic. The liver takes the brunt. That’s where most of your body’s iron is stored. Over time, excess iron causes inflammation, scarring, and eventually, cirrhosis. Once cirrhosis sets in, your liver can’t heal. The risk of liver cancer jumps dramatically.

But it doesn’t stop there. Iron also settles in the pancreas, wrecking insulin-producing cells and triggering diabetes. It coats the heart muscle, leading to irregular rhythms or heart failure. It affects the pituitary gland, lowering testosterone and causing loss of libido or erectile dysfunction in men. Women are protected longer-until menopause-because monthly blood loss naturally removes iron.

By the time symptoms appear, you’re often already damaged. Fatigue? 74% of patients report it. Joint pain? 65%. Skin that looks bronze or gray? That’s classic. Diabetes? 1 in 4. These aren’t random side effects. They’re direct results of iron toxicity.

How Do You Know If You Have It?

Two simple blood tests can catch it early: serum ferritin and transferrin saturation.

Ferritin measures how much stored iron you have. Normal is under 300 ng/mL for men, under 200 ng/mL for women. If yours is over 1,000 ng/mL, you’re at high risk for liver damage. Transferrin saturation tells you how much iron is floating in your blood. Normal is under 45%. If it’s over 45%, your body is absorbing too much. That’s a red flag.

But these tests alone aren’t enough. You need genetic testing to confirm. The HFE gene mutation C282Y is responsible for 80 to 95% of cases. If you have two copies (homozygous), you’re at high risk. Compound heterozygotes (C282Y/H63D) have a lower risk, but still need monitoring.

Doctors don’t always order these tests. That’s the problem. If you have unexplained fatigue, joint pain, or elevated liver enzymes, ask for ferritin and transferrin saturation. Don’t wait for symptoms to get worse.

Phlebotomy: The Treatment That Works

There’s no pill for hemochromatosis. But there’s a treatment that’s been used since the 1950s-and it’s free, safe, and effective: phlebotomy.

It’s just like donating blood. A needle goes in, 450 to 500 mL of blood comes out. Each pint removes about 200 to 250 mg of iron. That’s the same amount you get from eating 30 steaks.

The process has two phases:

  1. Induction: Weekly phlebotomy until ferritin drops to 50 ng/mL. For someone with ferritin at 2,500 ng/mL, that’s 30 to 60 sessions-usually over 12 to 18 months.
  2. Maintenance: Once iron levels are normal, you switch to every 2 to 4 months to keep ferritin between 50 and 100 ng/mL. Most people need 4 to 6 sessions a year.

Think of it like draining a flooded basement. You don’t just stop once the water looks low. You keep pumping until the floor is dry-and then you check it regularly so it doesn’t flood again.

Most insurance covers therapeutic phlebotomy. Costs? Often $0 to $50 per session. Compare that to iron chelation drugs, which cost $25,000 to $35,000 a year and come with side effects like nausea, kidney damage, or allergic reactions.

What Happens If You Don’t Treat It?

Here’s the hard truth: if your ferritin is above 1,000 ng/mL when you’re diagnosed, you have a 50 to 75% chance of already having cirrhosis. Once cirrhosis develops, your 10-year survival rate drops from 95% to 60%.

And it’s not just liver damage. People with untreated hemochromatosis are 20 times more likely to develop liver cancer. They’re more likely to die from heart failure or diabetes complications. The damage is irreversible.

But here’s the flip side: if you catch it early-before ferritin hits 1,000 ng/mL-phlebotomy can prevent almost all complications. A study from the University of Western Ontario found that 99% of cirrhosis and liver cancer cases could be avoided with timely treatment.

Real Stories, Real Delays

One Reddit user, u/HemoWarrior, spent eight years with joint pain and exhaustion. Doctors called it arthritis. Then depression. Then “just getting older.” His ferritin was 2,850 ng/mL when finally diagnosed. He needed 62 phlebotomies over 15 months. He says: “I felt like a new person after year one. But I almost didn’t make it.”

That’s not rare. On patient forums, 68% say they saw 3 to 5 doctors over 5 to 7 years before getting the right diagnosis. Primary care doctors rarely test for transferrin saturation. It’s not on the standard panel. You have to ask.

And even after diagnosis, many stop treatment. “I feel fine now,” they say. But iron doesn’t stop building up. Maintenance therapy isn’t optional. It’s lifelong.

Who Should Get Tested?

You should get tested if:

  • You have unexplained fatigue, joint pain, or loss of libido
  • Your liver enzymes (ALT, AST) are high
  • You have type 2 diabetes without obesity
  • You have heart rhythm problems with no clear cause
  • You’re of Northern European descent and have a family member with hemochromatosis

And if you’ve been diagnosed? Test your siblings, children, and parents. First-degree relatives have a 25% chance of carrying two faulty genes. Cascade testing saves lives.

What’s New in Treatment?

Phlebotomy isn’t going anywhere. But science is looking ahead. Researchers are testing drugs that mimic hepcidin-the hormone your body should be making. One drug, PTG-300, reduced iron absorption by over half in early trials. It’s not available yet, but it could one day replace phlebotomy for people who can’t tolerate it.

Also, MRI scans now measure liver iron without a biopsy. The R2* technique gives doctors a clear picture of iron buildup-no needles, no risk. That’s huge. It means you can monitor progress safely, over and over.

Living With Hemochromatosis

Once you’re on maintenance phlebotomy, life gets normal. You can eat meat. You can drink alcohol in moderation (but not if you already have liver damage). You can exercise. You can live to 80.

But you have to stay on track. Skip your phlebotomy for a year? Iron creeps back. You’re back to square one.

Some people struggle with vein access as they age. Others can’t find a clinic that does therapeutic phlebotomy-blood banks often won’t accept it. Talk to your doctor. They can help you find a specialized center or even arrange home visits in some cases.

The biggest risk? Complacency. You feel fine. So you think you’re cured. You’re not. You’re managed. Like diabetes or high blood pressure, this is a lifelong condition. But unlike those, it’s completely reversible-if you act early.

Final Thought: Don’t Wait for the Symptoms

Hemochromatosis doesn’t announce itself. It sneaks in. By the time you feel it, it’s already hurt you. But the tools to stop it are simple, cheap, and proven. Ask for your ferritin and transferrin saturation. If you’re at risk, get the genetic test. If you’re diagnosed, stick with phlebotomy. It’s not glamorous. But it’s the difference between a normal life and a failing liver.

Iron doesn’t care how you feel. But you can care enough to act before it’s too late.

Can hemochromatosis be cured?

No, hemochromatosis can’t be cured because it’s genetic. But it can be completely managed with lifelong phlebotomy. Once iron levels are normalized and maintained, patients live normal lifespans with no organ damage. The goal isn’t cure-it’s prevention of complications.

Is phlebotomy the same as donating blood?

Yes, the procedure is identical. Blood is drawn from a vein, usually in the arm, and 450-500 mL is removed. The difference is in purpose: donation helps others; therapeutic phlebotomy treats your own iron overload. Most blood banks allow therapeutic donations if you have a doctor’s note, and many cover the cost.

Can I eat iron-rich foods if I have hemochromatosis?

Yes, you don’t need to avoid red meat, spinach, or fortified cereals. Your body absorbs too much iron regardless of diet. The problem isn’t what you eat-it’s your genes. But avoid vitamin C supplements with meals, as they boost iron absorption. Also, avoid alcohol if you have liver damage, as it speeds up scarring.

Why do men get diagnosed more often than women?

Women lose iron monthly through menstruation until menopause, which delays iron buildup. Men start accumulating iron from their 20s with no natural outlet. By age 40 to 50, men often show symptoms. Women typically don’t develop signs until after menopause, which is why they’re diagnosed later.

What if I can’t tolerate phlebotomy?

If you’re anemic, have heart failure, or can’t access veins, iron chelation drugs like deferasirox are an option. These bind to iron and remove it through urine or stool. But they’re expensive, have side effects, and are only used when phlebotomy isn’t possible. Most patients do fine with regular blood draws.

Should my family be tested if I have hemochromatosis?

Yes. First-degree relatives-parents, siblings, children-have a 25% chance of having two faulty HFE genes. Even if they don’t have symptoms, early detection prevents organ damage. Genetic testing is affordable now-under $300-and covered by many insurers. Cascade screening is the most effective public health tool we have for this condition.
