Although experts do not fully understand why some people get gout and others do not, many causes and risk factors of gout are well established.

Sex

Experts estimate men are 4 to 10 times more likely to have gout than women. Women’s risk of developing gout goes up during menopause (estrogen seems to have protective effects).,

Age

Many people have their first episode of gout between the ages of 30 and 50, and the risk of gout continues to increase with age. It is estimated that less than 3% of men under the age of 50 and nearly 12% of men aged 70 to 79 have had at least one episode of gout.,

Race

African American men are nearly twice as likely to report having had gout as Caucasian men.,

Family History

Research suggests that certain genes that influence kidney function (SLC2A9 and ABCG2) and gut function (ABCG2) increase the risk of developing gout. These genes may make the body more prone to accumulating uric acid and developing the uric acid crystals that lead to gout.

Excess Weight

People who are overweight have a greater risk of developing gout. They are also more likely to develop gout at a younger age.

Diet

The risk of a gout flare-up is increased by the consumption of alcohol, sugary foods and drinks, meat, and seafood, which are high in purines. (Beans, fruits, and vegetables do not seem to increase risk, even if they are high in purines.)

Alcohol Use

Drinking beer, wine, or liquor increases the likelihood of a gout attack. A study of 724 people diagnosed with gout found that consuming between 1 and 2 alcoholic drinks increased the likelihood of a flare-up by 36%.

Certain Medications

Taking certain medications can increase the risk of hyperuricemia and gout attacks. Common examples of these medications include:

  • Diuretics, which are sometimes called water pills
  • Low-dose aspirin
  • Cyclosporine, an immunosuppressant sometimes prescribed to people who have rheumatoid arthritis or psoriasis, or who have had an organ transplant
  • Niacin (nicotinic acid), which is used to prevent and treat niacin deficiency (pellagra)
  • Teriparatide, a synthetic hormone used to treat osteoporosis

This is not necessarily a complete list. People who take medications or supplements are advised to talk to their doctor or pharmacist about how their medications may influence gout risk.

Chronic Renal Failure

A person with chronic renal failure no longer has fully functioning kidneys. When the kidneys’ ability to flush out uric acid is compromised, gout may develop.

A Trigger Event, Such as Injury, Surgery, or Medical Therapy

Specific events can trigger a change in body chemistry and bring on a gout flare-up. Such events include, but are not limited to,:

  • Infection
  • Repetitive microtrauma from joint overuse
  • Traumatic injury
  • Surgery
  • Illness
  • Sudden and dramatic weight loss

Interestingly, many people who experience an episode of gout may not ever have symptoms again, or at least not for several years. People who do experience gout symptoms repeatedly may notice that episodes get longer and more severe. Gout and its precursor, hyperuricemia, should be addressed to prevent future joint damage.
