6 Signs of Iron Overload Most People Blame on Getting Older

By Curtis Jones · October 20, 2026

Most health advice about iron is about getting enough of it. For some people the problem runs the other way. In hemochromatosis, the body absorbs too much iron from food every day, and the extra slowly builds up in the liver, heart, pancreas, glands, and joints, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

It is more common than its name suggests. NIDDK says about 1 in 15 people of Northern European ancestry carry at least one copy of the main gene change, and about 1 in 225 carry two copies, which puts them at risk. It can take decades for iron to reach harmful levels, so symptoms typically begin after age 40. Men are more likely to develop symptoms, and women tend to develop them about 10 years later, usually after menopause, because monthly blood loss had kept their iron lower.

That timing is the trouble. The Mayo Clinic says the early signs of iron overload often overlap with those of other common conditions. Here are six that are easy to chalk up to age.

Tiredness that doesn’t lift. NIDDK lists feeling tired or weak first among the symptoms. Mayo puts weakness and tiredness at the top of its early signs, too.

Aching joints, especially the knees and hands. NIDDK names joint pain in those spots as a symptom, and arthritis is one of the complications iron damage can cause. It is easy to assume it is ordinary wear and tear.

Pain in the upper right belly. NIDDK lists pain in the abdomen over the liver. Mayo says the liver is where much of the extra iron is stored, and over time it can scar, a condition called cirrhosis.

Losing interest in sex. NIDDK says iron damage can lower sex hormone levels, leading to loss of interest in sex and erectile dysfunction.

A change in skin color. Iron deposits can make the skin look gray, metallic, or bronze, NIDDK says. It can come on so gradually that it is easy to miss.

New diabetes or heart rhythm trouble. Mayo says iron overload can damage the pancreas, which can lead to diabetes, and can cause heart rhythm changes and heart failure. Doctors sometimes call the combination of diabetes and bronze skin “bronze diabetes.”

Not everyone with the gene change gets sick. NIDDK notes that hemochromatosis may not cause symptoms for many years, and some people never have any. Heavy drinking and other liver disease, especially hepatitis C, raise the risk of serious iron overload.

Finding it usually starts with ordinary blood work. NIDDK says doctors check iron, transferrin, and ferritin levels, and a genetic test can confirm the most common form. If a parent, brother, sister, or child has hemochromatosis, NIDDK says you should be checked, too.

Treatment is simple. Doctors usually remove about a pint of blood at a time, often once or twice a week at first and eventually just two or three times a year once iron levels come down. NIDDK calls it simple, inexpensive, and safe, and says early treatment can prevent complications. Your doctor may also tell you to avoid supplements that contain iron or vitamin C, which increases iron absorption, so check the label on your daily multivitamin.

If several of these signs sound familiar, ask your doctor whether your next blood test should include an iron panel and ferritin.
