New Global Study Reveals the Real Cause of Gout—And It’s Not Your Diet

Massive Study Reveals Where Gout Comes From, And It’s Not What We Thought

A Massive Study Just Changed What We Know About Gout

For years, most people believed gout was mainly caused by eating rich foods or drinking too much alcohol. But a huge global study has now turned that idea upside down. According to new research, genetics—not lifestyle—is the biggest driver of gout.

What the Study Found

In 2024, scientists analyzed genetic data from 2.6 million people across 13 international DNA databases. Out of these, more than 120,000 people had gout.

By comparing the DNA of people with and without gout, researchers identified 377 genetic regions linked to the condition—149 of them were completely new discoveries.

This means the roots of gout run much deeper than food choices or habits.
Yes, lifestyle still matters—but your genes may already be setting the stage long before any symptoms appear.

Why This Matters

Epidemiologist Tony Merriman from the University of Otago explains it clearly:

“Gout is a chronic disease with a genetic basis and is not the fault of the sufferer.”

This myth that gout comes from “bad habits” can make people feel guilty or embarrassed. As a result, many avoid treatment—even though gout is treatable and manageable.

How Gout Actually Happens

Gout starts when too much uric acid builds up in the blood. This excess acid forms sharp, needle-like crystals that settle in your joints. When your immune system tries to fight these crystals, the result is inflammation, swelling, and intense pain.

The study shows that genetics influence every step of this process, including:

  • how the body transports uric acid
  • how likely uric acid crystals are to form
  • how strongly the immune system reacts

This deeper understanding opens new doors for better treatments—even the possibility of repurposing existing drugs.

A Step Toward Better Care

There were some limitations: most participants were of European ancestry, and some data came from self-reported cases instead of medical diagnosis. Still, the scale of the study makes it one of the most important breakthroughs in gout research.

Researchers hope their findings will:

  • improve treatment options
  • make care more accessible
  • reduce stigma
  • encourage people to seek medical help without hesitation

As Merriman says:

“Gout deserves more health-spend resources and greater prioritization in the health system.”
