Dealing With Gout

Dealing With Gout

by Berkeley Wellness  |  

Gout was once seen as a rich man’s disease because it was associated with overindulgence in food and drink (think of gluttonous Henry VIII of England) and because more men than women develop it.

But gout strikes both sexes and people in all walks of life. It’s estimated that eight million Americans have gout (including 10 percent of people over 65) and that its incidence has nearly tripled in the past 25 years. That’s not surprising, since gout is linked to obesity, which is also on the rise.

A buildup of uric acid

Recognized since the time of Hippocrates, gout is a form of inflammatory arthritis. It commonly results from an excess of uric acid, a waste product formed from the breakdown of nitrogen compounds called purines, which are found naturally in the body and certain foods.

As uric acid builds up in the blood—either because too much is made or, more typically, too little is excreted by the kidneys—it can form crystal deposits in joints and other body parts. The body sees these crystals as foreign invaders and releases inflammatory substances that make the area hot, red, swollen and extremely tender.

Gout most commonly affects joints—notably the ankles, feet, knees, wrists, elbows and hands—with most first attacks occurring in the big toe. Sometimes there is fever. Inflammation often subsides in a few days, but a severe attack can last a few weeks.

Men are more susceptible to gout at younger ages because their blood levels of uric acid typically begin to rise after puberty. But women catch up after menopause. Gout seems to have a genetic component. Certain medications (such as aspirin, diuretics and high-dose niacin), alcohol (especially large amounts), surgery, physical trauma and perhaps even hot weather (because of dehydration) may increase uric acid levels and trigger gout. Recent research suggests that even modestly elevated blood levels of lead increase the risk of high uric acid levels and gout.

The impact of diet is debatable, but studies have generally linked gout to high intakes of meat and seafood, which are rich in purines, but not to purine-rich plant foods such as peas, beans, lentils, spinach, mushrooms and cauliflower or total protein intake. Dairy may reduce the risk of developing gout and/or having flare-ups.

Elevated uric acid in the blood and gout itself are linked to an increased risk of hypertension, perhaps because uric acid impairs the ability of blood vessels to dilate, contributes to kidney disease and/or activates hormones that can boost blood pressure. Thus, certain drugs used to lower uric acid may improve blood vessel function and reduce blood pressure. Research has also linked high uric acid to coronary artery disease.

Fending off gout attacks

If you think you have gout, see a doctor. NSAIDs (nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen, but not aspirin), ice and rest are often recommended to relieve the inflammation and pain from flare-ups.

Your doctor may prescribe other anti-inflammatory drugs and corticosteroids. If you have recurrent attacks, he or she may prescribe drugs that lower production of uric acid and/ or increase its excretion.

A good reason to see a doctor and get your gout under control is that untreated gout, over time, can cause arthritis and permanently damage joints; elevated uric acid can also cause kidney stones. And treating it may reduce the risk of hypertension and heart disease.

Other ways to help control gout

Lose weight if you are overweight. But don’t go on crash diets or fast, since that may increase uric acid levels.

Limit alcohol, especially beer, which is high in purines. Moderate wine drinking does not seem to increase risk, however.

Go easy on red meat (particularly organ meats) and certain kinds of seafood (notably herring, sardines, shrimp, scallops and anchovies). Be careful of high-protein diets that include a lot of red meat and saturated fat. In contrast, dairy products may be protective.

Cut down on foods and beverages sweetened with high-fructose corn syrup or sucrose. These are both major sources of fructose, which in excessive amounts can increase uric acid production.

Eat fruits and vegetables rich in vitamin C, such as oranges, strawberries, peppers and broccoli, which may reduce uric acid levels. Some preliminary research suggests that cherries help reduce inflammation from gout and other forms of arthritis. But don’t believe cherry-pie-in-the-sky claims that cherries or their juice are a cure.

Drink enough fluids to avoid dehydration.

Enjoy your coffee, including decaf —it may reduce the risk of gout somewhat, according to a 2010 study of 89,000 older female nurses.

Avoid medications that can increase uric acid levels. Talk to your doctor about which ones do this. These include aspirin as well as diuretics taken for hypertension.
