Gout

What is gout?

Gout is caused by elevated levels of uric acid, a natural waste product that forms when your body breaks down purines found in certain foods and drinks. Normally, uric acid dissolves in your blood, passes through the kidneys, and is excreted in urine.

When uric acid levels get too high, crystals can form in the joints, triggering inflammation and pain. While gout most often affects the big toe, it can also appear in the ankles, knees, wrists, or fingers.

Some people experience sudden gout flare-ups followed by periods of no symptoms, while others notice ongoing stiffness or discomfort over time. Without treatment, attacks typically become more frequent and affect more joints over time.

Symptoms of gout

Gout attacks often begin suddenly, frequently overnight, and can reach peak intensity within hours. They may last from a few days to a couple of weeks.

Common gout symptoms include:

• Sudden, intense joint pain (often in the big toe)

• Swelling, warmth, and redness in the affected joint

• Tenderness, where even light touch is painful

• Limited joint movement during a flare-up

• Lingering stiffness or discomfort after pain subsides

In more advanced or long-term cases, you may experience:

• Repeated flare-ups in different joints

• Hard uric acid deposits under the skin (called tophi)

• Joint damage or deformity if left untreated

• Kidney stones, formed from uric acid crystals deposited in the urinary tract

Because early symptoms can be mild or infrequent, many people dismiss them as temporary. That’s why early gout testing is so important, it brings clarity and helps prevent progression.

What causes gout?

Gout develops when uric acid production exceeds the kidneys' capacity to excrete it. This imbalance arises from a combination of metabolic, dietary, genetic, and lifestyle factors:

• Diet: high intake of red meat, seafood, or sugary drinks.

• Alcohol: especially beer and spirits, which raise uric acid levels.

• Kidney function: reduced kidney efficiency directly impairs uric acid clearance.

• Genetics: family history of gout or high uric acid.

• Medications: certain diuretics or blood pressure medicines.

• Obesity and metabolism: insulin resistance reduces renal uric acid excretion and increases production.

• Dehydration: low fluid intake reduces uric acid excretion.

It is worth emphasising that gout is not simply a dietary condition. While food and drink choices matter, the majority of uric acid in the body comes from cellular turnover rather than diet alone, which is why metabolic health, kidney function, and genetics are equally important factors.

How do you detect gout?

Gout is primarily detected through blood tests, with imaging playing a supporting role in assessing joint damage or confirming crystal deposits in more advanced cases.

Blood tests: Measuring serum uric acid is the most direct way to identify hyperuricaemia, the underlying driver of gout, before or between flare-ups. When reviewed together, these markers show whether your body is accumulating uric acid and how well your kidneys are managing its removal.

• Uric acid: measures the primary driver of gout and the risk of crystal formation.

• Creatinine, cystatin C and eGFR: a dual-marker assessment of how efficiently your kidneys clear uric acid.

• Urea: monitors kidney function and protein metabolism.

• CRP: identifies active inflammation during a flare-up.

• HbA1c, glucose and insulin: evaluates insulin resistance, which impairs uric acid excretion.

• Lipid profile: provides cardiovascular context, as gout often clusters with high cholesterol.

• MRI: visualizes crystal deposits (tophi), bone erosions, and soft tissue damage.

MRI: While blood tests are the primary detection tool for gout, MRI has a role in more advanced assessment. It can identify uric acid crystal deposits (tophi) in soft tissues and tendons, detect bone erosions caused by chronic crystal deposition, and assess joint damage.

Elfcare’s blood tests for gout include uric acid and kidney function markers, giving you an early view of your risk while our full body MRI covers joints including the knees and spine, where gout can manifest, and targeted joint MRI is also available if specific joint assessment is needed.

Why early detection matters

Gout often develops slowly, and your body can tolerate high uric acid levels for years before crystals form. Once they do, flare-ups can be painful and recurring, but early insight helps you manage or even prevent progression.

Detecting high uric acid early allows you to:

• Adjust your diet and hydration habits

• Review medications that may raise uric acid

• Support kidney health through lifestyle changes

• Track progress through follow-up testing

By understanding your uric acid balance before symptoms arise, you can stay in control and protect your joints, kidneys, and overall metabolic health.

In short, early gout detection means fewer surprises later.

How Elfcare can help

Elfcare provides a dual-diagnostic approach to gout by combining advanced blood analytics with precision imaging.

Blood panels: We measure uric acid alongside kidney and metabolic markers (Cystatin C, eGFR, CRP) to identify gout risk and its common companions, such as hypertension and diabetes. The process is simple: we take a small blood sample, analyse and share your results in clear, accessible language.

Full body MRI: Our scans detect crystal deposits, tophi, and joint damage that traditional tests might miss.

We focus on early prevention and clear results. If findings are abnormal, we manage follow-up diagnostics or coordinate referrals to specialists to ensure seamless treatment.
