Gout Is Rising in the Philippines. Filipino Men Have a Genetic Reason to Pay Attention.

What the Global and Regional Data Shows

Globally, an estimated 56.5 million adults were living with gout in 2021, compared to 22.3 million in 1990, representing a more than doubling of global gout prevalence over 31 years according to the PMC11983511 analysis of the Global Burden of Disease Study published in 2025. The incidence of new gout cases increased by 136.1 percent from 1990 to 2021. That increase reflects the convergence of multiple trends: rising obesity rates, increasing consumption of fructose-rich foods and beverages, greater use of diuretics and low-dose aspirin in aging populations, and, increasingly, the interaction between genetic predisposition and westernized diet patterns. Gout is the most common form of inflammatory arthritis worldwide, and its prevalence continues to climb.

In the Western Pacific region, including the Philippines, gout has long been recognized as disproportionately prevalent. Studies of Filipino communities in Hawaii, Alaska, and the continental United States documented elevated serum uric acid levels and higher gout prevalence among Filipinos compared to non-Filipino counterparts as far back as the 1960s. More recently, a study examining Filipinos in Guam found a gout prevalence of 21.4 percent among the Filipino population studied, a figure that reflects both the genetic predisposition and the dietary and metabolic environment that activates it. Within the Philippines itself, population-based surveillance data on gout remains limited, but clinical data from the University of the Philippines Manila-Philippine General Hospital and epidemiological research consistently document gout as a significant and underdiagnosed burden in the male population.

Why Filipinos Are Genetically Predisposed to Gout

The biological mechanism of gout begins with uric acid, the end product of purine metabolism. Purines are compounds found in many foods, particularly red meat, organ meats, shellfish, and alcohol, and produced naturally by the body during cell turnover. Normally, uric acid dissolves in the blood, passes through the kidneys, and is excreted in urine. When either too much uric acid is produced or too little is excreted, levels in the blood rise above the saturation threshold. At that point, urate crystals begin to deposit in joints and surrounding soft tissues, triggering the intense inflammatory response that causes a gout attack.

Research has consistently found that Filipinos have a reduced capacity for urinary uric acid excretion compared to Caucasian populations. A major part of the explanation lies in a specific genetic variant: the rs2231142 G-to-T polymorphism in the ABCG2 gene, which encodes a uric acid transporter responsible for secreting urate into the intestine for excretion. When this transporter is impaired, uric acid accumulates in the blood even at purine intake levels that would not cause hyperuricemia in individuals without the variant. Research examining this variant in Filipino cohorts found that the high-risk TT genotype was present in 21 percent of Filipinos studied, compared to just 1 percent of Caucasians, 9 percent of Han Chinese, and 0.1 percent of African Americans. Filipinos carry the highest documented prevalence of this gout-risk genotype of any population in the published literature.

This genetic reality has a direct implication for how gout risk in Filipino men should be understood. The standard narrative positions gout as a disease of dietary excess, brought on by overindulgence in red meat, alcohol, and rich food. For Filipinos, the biological baseline is different. A Filipino man with the high-risk ABCG2 genotype may develop hyperuricemia and gout at purine intake levels that would be entirely safe for a man of European ancestry. This is not about willpower or diet discipline. It is a metabolic architecture that places Filipino men at elevated risk regardless of whether they eat particularly poorly.

What Gout Actually Does to the Body Beyond the Painful Attack

A gout attack, in its acute form, is among the most severe pain experiences in clinical medicine. The sudden onset of excruciating pain, most commonly in the big toe but also in the ankle, knee, wrist, and elbow, typically peaks within 24 hours and resolves within one to two weeks. Many men treat this as an isolated event, rest it out, and return to their usual pattern. The danger of this approach is that gout is a progressive disease when uric acid levels remain elevated between attacks. Each attack deposits additional urate crystals in and around joints, and over years this accumulation causes tophi, visible deposits of crystallized urate under the skin, progressive joint destruction, and permanent disability in some cases.

Beyond the joints, chronically elevated uric acid carries systemic consequences that are increasingly documented in the research literature. Hyperuricemia is independently associated with hypertension, chronic kidney disease, cardiovascular disease, and metabolic syndrome. The kidneys are particularly vulnerable: urate crystals can deposit in renal tissue, impairing kidney function and accelerating CKD, while the inflammatory burden of recurrent gout attacks adds further insult to renal blood flow and tubular function. A UP-PGH cross-sectional study of 121 Filipino gout patients by Tee et al., published in Research and Reports in Urology in 2020, found that 86.8 percent were male and that comorbidities were common, including hypertension, CKD, and dyslipidemia, reflecting the same overlapping cardiometabolic risk profile that characterizes the broader Filipino NCD burden.

• Men account for approximately 80 percent of gout cases globally; the disease is far less common in women before menopause because estrogen promotes renal uric acid excretion
• The first gout attack typically occurs between the ages of 30 and 50 in Filipino men, earlier than in European populations, consistent with the higher genetic predisposition
• Alcohol, particularly beer and spirits, raises uric acid both by increasing purine production and by reducing renal excretion of urate; beer has the highest risk association of any beverage
• Fructose, found in sweetened beverages and processed foods, raises uric acid independently of purine content and is increasingly recognized as a major dietary driver of hyperuricemia globally
• Low-fat dairy products, vegetables, and adequate hydration are associated with lower uric acid levels and may partially offset dietary purine load

Diagnosis, Treatment, and What Filipino Men Are Missing

Gout is clinically diagnosed through a combination of characteristic symptoms, elevated serum uric acid, and in definitive cases, identification of monosodium urate crystals in joint fluid under polarized light microscopy. A serum uric acid test, available at most Philippine laboratories and health centers, is the primary screening tool. A level above 360 micromoles per liter in women or 420 micromoles per liter in men is defined as hyperuricemia and represents the threshold above which urate crystallization risk rises substantially. Many Filipino men have elevated uric acid levels on routine bloodwork and receive no management beyond a dietary handout, partly because the asymptomatic period before a first gout attack gives no urgency to the finding.

When gout is diagnosed and attacks recur, urate-lowering therapy is the evidence-based standard of care. Allopurinol, the most widely used urate-lowering agent, works by inhibiting xanthine oxidase, the enzyme responsible for the final step in uric acid production. It is on the Philippine National Formulary, available at most health facilities, and inexpensive. When taken consistently, it reduces serum uric acid to below the crystallization threshold, prevents further attacks, dissolves existing tophi over time, and reduces the cardiovascular and renal risks associated with sustained hyperuricemia. The challenge is that many patients stop taking it after their acute attack resolves, misunderstanding it as a treatment for pain rather than a long-term metabolic intervention. PhilHealth covers gout-related outpatient consultations and laboratory monitoring under applicable benefit packages, and allopurinol is available at subsidized cost through the PITC Pharma retail pharmacy network and selected Botika ng Bayan outlets.
