What Is Gout?

Gout is an inflammatory arthritis caused by the deposition of monosodium urate (MSU) crystals in joints and periarticular tissues. When serum uric acid exceeds its saturation point (approximately 6.8 mg/dL), urate crystallizes in the synovial fluid of joints, producing intense inflammatory attacks characterized by severe pain, swelling, redness, and heat, classically affecting the first metatarsophalangeal joint (big toe) but also the ankle, knee, wrist, and fingers.

Gout affects approximately 9.2 million Americans, and its prevalence has doubled over the past two decades, paralleling the rise of metabolic syndrome, obesity, and high-fructose corn syrup consumption. This correlation is not coincidental. Gout is fundamentally a metabolic disease. Approximately 90 percent of hyperuricemia results from impaired renal uric acid excretion, not from overproduction. Insulin resistance upregulates the URAT1 transporter in the proximal renal tubule, reabsorbing uric acid back into the bloodstream rather than excreting it. This mechanism directly links gout to the same metabolic dysfunction that produces type 2 diabetes, hypertension, and cardiovascular disease.

Why Gout Matters

Common Symptoms

Root Causes: A Functional Medicine Perspective

Hyperuricemia is the result of an imbalance between uric acid production and excretion. Both sides have identifiable, modifiable drivers.

Insulin Resistance and Renal Urate Excretion

Insulin resistance is the most consequential and most overlooked mechanism in gout. Hyperinsulinemia upregulates the URAT1 transporter in the proximal renal tubule, increasing uric acid reabsorption and decreasing excretion. This directly links gout to metabolic syndrome. The patient with gout, hypertension, elevated triglycerides, and visceral adiposity has a single upstream metabolic driver: insulin resistance is producing all of these conditions simultaneously through different downstream pathways.

Fructose Metabolism

Fructose is unique in its metabolism. When fructose is phosphorylated in the liver by fructokinase, it rapidly depletes ATP. The resulting AMP is degraded through the purine pathway (AMP to IMP to hypoxanthine to xanthine to uric acid), producing uric acid as a direct metabolic byproduct. This mechanism makes high-fructose corn syrup, sucrose (50 percent fructose), and concentrated fruit juice more potent drivers of hyperuricemia than dietary purines from meat. A 12-ounce soda produces more uric acid than a serving of organ meat.

Purine Overload and Alcohol

Dietary purines from organ meats, shellfish, and certain fish contribute to uric acid production through xanthine oxidase-mediated conversion. Beer contains both purines (from brewer's yeast) and alcohol (which impairs renal uric acid excretion and increases purine turnover). Spirits impair excretion without the purine contribution. Wine has the weakest association with gout of all alcoholic beverages.

Medication and Renal Factors

Thiazide and loop diuretics impair renal uric acid excretion, producing iatrogenic hyperuricemia that triggers gout in susceptible patients. Low-dose aspirin (below 1g) reduces uric acid excretion. Cyclosporine and tacrolimus produce hyperuricemia through renal effects. Chronic kidney disease progressively reduces uric acid clearance capacity.

Conventional vs Functional Medicine Approach

Key Labs to Evaluate

How to Interpret These Labs Together

Common Patterns Seen in Patients

• The patient on allopurinol with persistent flares and metabolic syndrome: uric acid reduced from 9.2 to 6.1 on allopurinol 300mg. Still having 2 to 3 flares per year. Fasting insulin 22. TG/HDL ratio 4.8. BMI 32. The allopurinol reduced uric acid production but the insulin resistance is still impairing excretion and the fructose intake is still driving production. Insulin sensitization, fructose elimination, and cherry concentrate alongside allopurinol eliminated flares and improved metabolic markers simultaneously.
• The patient whose gout started when they began a diuretic: new onset gout 6 months after starting hydrochlorothiazide for hypertension. Thiazide diuretics impair renal uric acid excretion. The gout was iatrogenic. Switching to a non-diuretic antihypertensive (losartan, which actually lowers uric acid) resolved the hyperuricemia. Concurrent blood pressure optimization through metabolic intervention.
• The 32-year-old with gout drinking 3 sodas per day: young onset gout. No family history. BMI 28. Fasting insulin 16. Three 20-ounce sodas daily (approximately 195g fructose/day from HFCS). The fructose is producing massive uric acid through ATP degradation in the liver, and the resulting insulin resistance is impairing excretion. Soda elimination alone reduced uric acid from 8.4 to 5.9 over 3 months without medication. Flares ceased.

What Most Doctors Miss

• Insulin resistance is the primary driver of hyperuricemia: 90 percent of hyperuricemia is from under-excretion, not overproduction. Insulin resistance through URAT1 upregulation is the most common mechanism. Fasting insulin is not part of standard gout evaluation.
• Fructose is a stronger driver than dietary purines: high-fructose corn syrup produces more uric acid through ATP degradation than dietary purines from meat. The "avoid red meat" advice addresses a secondary contributor while ignoring the primary one.
• Gout is a cardiovascular risk marker: hyperuricemia independently predicts cardiovascular events. The patient with gout should receive the same cardiovascular risk assessment as the patient with a family history of heart disease, because the metabolic driver is the same.
• Diuretics cause gout: thiazide and loop diuretics impair renal uric acid excretion. Every patient who develops gout on a diuretic should have the medication reconsidered.

When to Seek Medical Care

If you experience recurrent acute joint inflammation (particularly in the big toe, ankle, or knee), have been diagnosed with hyperuricemia, have metabolic syndrome components (hypertension, dyslipidemia, visceral adiposity), or have gout that recurs despite allopurinol, a comprehensive metabolic evaluation including fasting insulin and cardiovascular risk assessment is warranted alongside standard gout management.

Frequently Asked Questions

How The Lamkin Clinic Approaches Gout

At The Lamkin Clinic, gout evaluation includes uric acid alongside comprehensive metabolic assessment: fasting insulin, HOMA-IR, triglyceride/HDL ratio, HbA1c, hs-CRP, renal function, and cardiovascular risk markers. Treatment addresses the metabolic disease producing the hyperuricemia: insulin sensitization, fructose elimination, cherry concentrate, vitamin C, and anti-inflammatory support alongside urate-lowering therapy when indicated. The goal is to treat the metabolic disease, not just the joint inflammation.
