What is gout, and how does it develop?
Gout is a microcrystalline arthropathy caused by the deposition of sodium urate crystals in the joints—a direct consequence of chronic hyperuricemia. Arnaud, Ph.D. in Pharmacy, emphasizes that a gout attack is a painful medical emergency requiring medical care—the supplements available in our joint pain line are intended for long-term support, never as treatments for acute attacks.
- Hyperuricemia: serum uric acid > 360 μmol/L (6 mg/dL)—the solubility threshold in the blood—above which urate crystals form preferentially in cold areas (big toe, ankle, knee)
- Gout attack: acute inflammation triggered by the phagocytosis of crystals by neutrophils—peak pain within 6–12 hours, redness, warmth, intense swelling—characterized by intolerance to even the slightest touch
- Chronic tophaceous gout: accumulation of tophi (uric acid deposits visible under the skin) after several years of untreated disease — irreversible joint deformities
- Gout affects 3–4% of the adult population—prevalence is increasing due to dietary changes and obesity
Which foods promote or prevent gout attacks?
Diet is the most accessible preventive measure—understanding purines can significantly reduce the frequency of attacks and baseline uric acid levels.
- Purine-rich foods to limit: organ meats (liver, kidneys, sweetbreads), anchovies, sardines, herring, mackerel, mussels, excessive amounts of red meat, concentrated meat broths—a 20–25% reduction in serum uric acid levels is possible with an appropriate diet
- Alcohol: Beer (rich in guanosine) and spirits increase uric acid production AND reduce its renal excretion—a double aggravating effect—to be avoided especially during attacks
- Sugary drinks (fructose): Fructose increases uric acid production via the nucleotide breakdown pathway—significantly reduce consumption of sodas and commercial fruit juices
- Protective foods: skim dairy products (reduce uric acid levels), coffee (moderately uricosuric), and sufficient water intake (≥ 2 L/day to promote renal excretion)
- Purine-rich vegetables (asparagus, mushrooms, spinach): plant purines are absorbed less efficiently than animal purines—moderation is sufficient; no strict exclusion
What natural remedies can support gout management?
Several natural compounds have been studied for their ability to reduce blood uric acid levels or uric acid-related inflammation—as a supplement to medical treatment (allopurinol, colchicine, NSAIDs) and only after approval by a doctor; they should never be used as a substitute during an acute flare-up.
- Cherry stems and cherries: Clinical studies show a reduction in serum uric acid levels and the risk of attacks with regular consumption of cherries or cherry extract — mechanism: inhibition of xanthine oxidase (the enzyme responsible for uric acid synthesis) + anti-inflammatory properties of anthocyanins
- Dandelion (Taraxacum officinale): traditional diuretic and uricosuric agent—promotes renal excretion of uric acid—EMA-recognized for supporting kidney function
- Turmeric (curcumin): well-documented natural anti-inflammatory — may reduce inflammation between flare-ups — in a bioavailable form (with piperine or liposomal)
- Omega-3 (EPA/DHA): reduce inflammatory mediators — provides ongoing support between attacks
- Intensive hydration: 2–3 L/day of water — dilutes uric acid in the blood and promotes its excretion by the kidneys — the simplest and most effective preventive measure
Which complications of gout require urgent medical attention?
Poorly controlled gout progresses to severe complications—medical follow-up with regular monitoring of serum uric acid levels is essential for patients with recurrent rheumatic conditions or chronic pain.
- Acute gout attack: urgent medical treatment (colchicine or NSAIDs)—do not wait, do not apply heat (worsens the attack)—local cold application may provide temporary relief
- Uric acid kidney stones: chronic hyperuricemia—acute, radiating lower back pain (renal colic)—medical emergency
- Tophus: large, deformity-causing uric acid deposits — surgery may be an option in severe cases
- Therapeutic goal of allopurinol: maintain serum uric acid levels < 360 μmol/L (ideally < 300 μmol/L in cases of tophi) — long-term treatment even in the absence of an attack
- Recurrent, unexplained joint pain warrants a serum uric acid test—gout is often underdiagnosed outside the classic presentation involving the big toe
