Beyond Gout: Elevated Uric Acid as a Hidden Driver of Insulin Resistance and Chronic Pain

Anjanaa Subramanian, MD (Natural Medicine), CFMP, MPT, PGDHM

 A functional medicine approach reveals how mildly elevated uric acid—often dismissed in conventional labs—can underlie metabolic dysfunction and chronic musculoskeletal pain, even in active, health-conscious individuals.

Abstract

A 35-year-old male software professional presented with chronic low back pain and borderline elevated HbA1c despite an active lifestyle and clean diet. Conventional diagnostics failed to identify an underlying cause. Functional assessment revealed elevated serum uric acid (8.2 mg/dL), implicating it as a driver of systemic inflammation, insulin resistance, and musculoskeletal symptoms. A targeted functional medicine approach, including herbal interventions, lifestyle modifications, and nutritional realignment, led to the resolution of pain and significant metabolic improvement within six weeks.

Patient Information

– Age/Sex: 35-year-old male
– Occupation: Software professional
– Lifestyle: Physically active; strength training 5–6 days/week, avoids refined sugar, tracks nutrition
– Presenting Complaint: Persistent low back pain and metabolic stagnation (HbA1c = 6.1%)

Introduction

Chronic pain has an underlying metabolic or inflammatory cause. While conventionally ignored, elevated uric acid has been shown to contribute to oxidative stress, insulin resistance, and inflammation, even in the absence of gout symptoms.^1-4 Linking those markers, like fasting insulin levels and serum uric acid levels, helps the clinician have a breakthrough in resistant pain cases.

Uric acid, a byproduct of purine metabolism, plays a paradoxical role in human physiology. While it is a potent antioxidant in extracellular environments, excessive accumulation can lead to pro-inflammatory states and metabolic dysfunction. Under normal physiological conditions, uric acid is excreted via the kidneys and intestines. However, factors such as high-purine diets, fructose consumption, renal dysfunction, metabolic syndrome, and certain genetic variants can impair its clearance, leading to hyperuricemia.

Recent research has shifted the perception of uric acid from a mere cause of gout to a broader metabolic disruptor. Elevated serum uric acid levels have been implicated in chronic low-grade inflammation, endothelial dysfunction, and insulin resistance, even in the absence of gout. Uric acid can stimulate the NLRP3 inflammasome, activate oxidative stress pathways, and impair nitric oxide production, all of which contribute to systemic inflammation and reduced insulin sensitivity.

This case study explores the mechanisms by which uric acid accumulates in the body, its physiological and pathological roles, and how it serves as a hidden driver of systemic inflammation and insulin resistance, often overlooked in conventional clinical assessments. Understanding these dynamics is crucial for identifying at-risk individuals and designing integrative strategies for metabolic and inflammatory disease reversal.

Case Presentation

Pain: Chronic dull low back pain, insidious onset, not responsive to physical therapy
Labs: HbA1c 6.1%, all other parameters within normal reference ranges
Imaging: Lumbar spine imaging is normal
Lifestyle factors: High exercise intensity, protein bars, and post-workout smoothies, high-fructose intake from “natural” products
Subjective complaints: Fatigue, sleep disruption, emotional frustration

Functional Assessment & Hypothesis

Despite a disciplined regimen, the patient’s symptoms suggested underlying metabolic dysregulation. A deeper evaluation revealed elevated serum uric acid (8.2 mg/dL), outside the optimal range, though often considered “normal” in conventional analysis.^1,2
Emerging research indicates that elevated uric acid can:
– Reduce insulin sensitivity^2,3
– Trigger systemic inflammation and oxidative stress^3,4

– Exacerbate oxidative stress and mitochondrial dysfunction
– Exacerbate chronic musculoskeletal symptoms^1,3

Intervention

Herbal Protocol

– Punarnava (Boerhavia diffusa) – Renal support and uric acid clearance
– Gokshura (Tribulus terrestris) – Diuretic and anti-inflammatory
– Guduchi (Tinospora cordifolia) – Immune modulation and inflammation control
– Berberine – Insulin sensitizer and metabolic regulator
– Triphala – Digestive detox and gut support
– Nirgundi (Vitex negundo) oil – Topical application for back pain

Lifestyle Adjustments

– Fructose restriction: Elimination of smoothies and energy drinks
– Whole food focus: Replaced protein bars with dal, millets, and vegetables
– Morning ritual: Warm lemon water with soaked fenugreek (methi) seeds
– Nervous system reset: Reduced training frequency, added breathwork, and evening walks
– Body awareness journaling: Daily tracking of energy, digestion, and mood patterns

Outcomes (After 6 Weeks) and Follow-up

– Pain: Complete resolution of low back pain
– Metabolic: HbA1c reduced from 6.1% to 5.6%
– Energy: Stable daytime energy, improved sleep, and recovery
– Mood: Reduction in frustration and mental fatigue

Discussion

This case highlights the clinical importance of interpreting “normal” labs through a functional lens. Uric acid, which is often overlooked, can act as a silent driver of insulin resistance, fatigue, and pain.^1-4 Elevated uric acid has been linked to endothelial dysfunction, impaired nitric oxide availability, and increased metabolic syndrome.^3,4 Uric acid also contributes to increased oxidative stress and mitochondrial impairment, which may explain chronic fatigue and muscle pain in some patients.³ Addressing the root cause through individualized herbal support and systemic recalibration yielded significant outcomes without pharmacological intervention.

Role of Uric Acid in Chronic Inflammation and Metabolism

Elevated serum uric acid impairs insulin signaling, increases mitochondrial oxidative stress, and promotes low-grade systemic inflammation via NLRP3 inflammasome activation.^1-3 Uric acid also reduces nitric oxide bioavailability, promoting endothelial dysfunction and metabolic rigidity.^2,4 These mechanisms create a biochemical terrain that fosters persistent pain, fatigue, and glucose dysregulation.

Mechanisms of Herbal Interventions

Each botanical in this protocol was selected for its ability to either enhance uric acid clearance, modulate inflammatory cytokines, or support insulin sensitivity.

Punarnava (Boerhavia diffusa)

Mechanism:

Stimulates diuresis by modulating renal tubular transport of electrolytes, aiding in uric acid excretion.Inhibits xanthine oxidase, the enzyme responsible for uric acid production, similar to allopurinol.⁵ Demonstrates anti-inflammatory effects by reducing TNF-α and IL-6 in animal models.⁶

Clinical Contribution: Reduces serum uric acid load and relieves kidney stress from hyperuricemia

Gokshura (Tribulus terrestris)

Mechanism:

Acts as a mild diuretic and nephroprotective agent. Reduces oxidative stress markers and normalizes serum creatinine and uric acid levels in hyperuricemic models.⁷ Enhances nitric oxide production, indirectly improving insulin signaling.⁸

Clinical Contribution: Supports renal elimination of uric acid and modulates vascular inflammation.

Guduchi (Tinospora cordifolia)

Mechanism:

Immunomodulatory; inhibits NF-κB pathway and downregulates proinflammatory cytokines like IL-1β, IL-6, and TNF-α.⁹ Antioxidant properties reduce ROS generation in metabolic tissues. Enhances insulin receptor sensitivity and glucose utilization.¹⁰

Clinical Contribution: Reduces systemic inflammation and insulin resistance—key drivers of both pain and uric acid retention.

Berberine

Mechanism:

Activates AMPK (adenosine monophosphate-activated protein kinase), enhancing insulin sensitivity and mitochondrial function.¹¹ Lowers uric acid through inhibition of xanthine oxidase.¹² Modulates gut microbiota to reduce endotoxin-induced inflammation

Clinical Contribution: Dual role in glycemic control and uric acid reduction, pivotal in breaking the pain-metabolism loop.

Triphala (Blend of Emblica officinalis, Terminalia bellirica, Terminalia chebula)

Mechanism:

Promotes gastrointestinal detoxification, reducing endotoxemia-driven inflammation. Antioxidant-rich; protects against oxidative damage in hepatic and renal tissues.¹³ In animal models, it has been shown to reduce uric acid levels and xanthine oxidase activity.¹⁴

Clinical Contribution:

Supports gut-liver axis detoxification and decreases metabolic inflammation.

Nirgundi Oil (Vitex negundo)

Mechanism:

Topical anti-inflammatory; inhibits COX-2 and prostaglandin synthesis locally.¹⁵ Reduces joint and muscular pain via suppression of peripheral inflammatory pathways

Clinical Contribution: Provides localized relief, reducing dependency on systemic analgesics.

Systemic Synergy and Functional Outcomes

Together, these herbs form a multidimensional therapeutic matrix. Punarnava and Gokshura improve uric acid elimination. Guduchi, Berberine, and Triphala reduce oxidative and cytokine stress. Berberine and Guduchi directly improve insulin receptor function. Nirgundi provides topical support, reinforcing systemic results without drug dependence. This approach aligns with systems biology principles: treating pain, inflammation, and metabolic dysfunction not as isolated symptoms, but as interconnected dysfunctions with common biochemical roots.

Conclusion

Elevated uric acid should be considered a modifiable risk factor in cases of unexplained metabolic stagnation and chronic musculoskeletal pain. Functional medicine offers a framework to resolve such patterns by supporting the body’s natural regulatory systems rather than suppressing symptoms.
