What Causes Gout?

Nearly 5 million Americans are living with gout, a painful form of inflammatory arthritis that most commonly affects the large joint in the big toe.

  • Men over age 40 are more likely to develop gout than women (although it can affect women after menopause)

Most common signs6

  • Severe and sudden pain at and around the affected joint
    • Crushing pain
    • Knife-like pain
  • Swelling that could spread beyond the affected joint
  • Redness
  • Chills, fever, and loss of appetite

Although gout was once known as the “disease of kings” because of its association with a rich diet, today we know there are a number of contributing factors that can cause gout.

Main causes4-6

  • Gout is caused by the build up of uric acid crystals in the joints
  • Uric acid is a substance that forms as the result of a breakdown of purines in the body and proteins in some foods we eat
  • Uric acid levels become high when the kidneys can’t remove uric acid from the body
  • High levels of uric acid in the blood lead to high levels in the joint
  • High levels of uric acid can lead to the formation of needle-like crystals, which cause painful swelling in the joint

Common risk factors4-6,9,10

  • Advancing age
  • Gender (gout affects 3 times as many men than women)
  • Obesity
  • Family history of gout
  • Regularly drinking too much alcohol
  • Ongoing use of certain medicines, including water pills, low-dose aspirin, cyclosporine (for patients who have had organ transplants), levodopa (for patients with Parkinson’s disease)
  • Patients who have had organ transplants
  • Exposure to lead
  • Thyroid problems
