Also indexed as: Arthritis (Gout)
Gout is a form of arthritis that occurs when crystals of uric acid accumulate in a joint,
leading to the sudden development of pain and inflammation.
People with gout either overproduce uric acid or are less efficient than other people, at
eliminating it. The joint of the big toe is the most common site to accumulate uric acid
crystals, although other joints may be affected.
What are the symptoms of gout? The pain of gout can arise suddenly and is often very intense. The
affected joint is usually red, swollen, and very tender to the touch. A low-grade fever may
also be present.
How is it treated? Acute gout attacks are typically treated
with colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs) such as
indomethacin (Indocin®) or naproxen sodium
(Aleve®, Anaprox®), and
corticosteroids. Resting the affected joint is commonly recommended. For long-term
treatment, doctors may prescribe medications such as
allopurinol (Lopurim®, Zyloprim®) to decrease uric acid production, or
probenecid (Benemid®) or sulfinpyrazone (Anturane®) to increase the excretion of
uric acid from the kidneys.
Dietary changes that may be helpful: Foods that are high in
compounds called purines raise uric acid levels in the body and increase the risk of gout. Restricting purine intake can reduce the risk of an
attack in people susceptible to gout. Foods high in purines include anchovies, bouillon, brains, broth, consommé, dried legumes, goose, gravy,
heart, herring, kidneys,
liver, mackerel, meat extracts, mincemeat, mussels,
partridge, fish roe, sardines, scallops, shrimp,
sweetbreads, baker’s yeast, brewer’s
yeast, and yeast extracts (e.g., Marmite, Vegemite).
Avoiding alcohol, particularly beer, or limiting alcohol intake to one drink per day or
less may reduce the number of attacks of gout.1 2 Refined sugars, including sucrose (white table
sugar) and fructose (the sugar found in fruit juice), should also be restricted, because they
have been reported to raise uric acid levels.3
According to a 1950 study of 12 people with gout, eating one-half pound of cherries or drinking an equivalent amount of cherry juice
prevented attacks of gout.4 Black, sweet yellow, and red sour cherries were all
effective. Since that study, there have been many anecdotal reports of cherry juice as an
effective treatment for the pain and inflammation of gout.
The active ingredient in cherry juice remains unknown.
Lifestyle changes that may be helpful: People who are overweight or have high
blood pressure are at greater risk of developing gout.5 However, weight loss
should not be rapid because restriction of calories can increase uric acid levels temporarily,
which may aggravate the condition.
Nutritional supplements that may be helpful: Large amounts of
supplemental folic acid (up to 80 mg per day) have
reduced uric acid levels in preliminary research.6 However, other studies have
failed to confirm the effectiveness of folic acid in treating people with
gout.7
In one small study, people who took 4 grams of vitamin
C (but not lower amounts) had an increase in urinary excretion of uric acid within a few
hours, and those who took 8 grams of vitamin C per day for several days had a reduction in
serum uric acid levels.8 Thus, supplemental vitamin C could, in theory, reduce the
risk of gout attacks. However, the authors of this study warned that taking large amounts of
vitamin C could also trigger an acute attack of gout by abruptly changing uric acid levels in
the body. Despite this concern, some doctors recommend vitamin C supplementation (sometimes
starting with one gram per day) as a method for reducing elevated uric acid levels.
In test tube studies, quercetin, a flavonoid, has inhibited an enzyme involved in the development of
gout.9 10 However, it is not known whether taking quercetin by mouth can
produce high enough quercetin concentrations in the body to achieve these effects. Although
human research is lacking, some doctors recommend 150–250 mg of quercetin three times
per day (taken between meals).
Are there any side effects or interactions? Refer to the individual supplement for
information about any side effects or interactions.
Herbs that may be helpful: Autumn crocus (Colchicum
autumnale) is the herb from which the drug
colchicine was originally isolated. Colchicine, a strong anti-inflammatory compound, is
used as a conventional treatment for gout. Both the herb and the drug have significant
toxicity and should only be used under the guidance of a physician.
Are there any side effects or interactions? Refer to the individual herb for
information about any side effects or interactions.
