Woke Up With Sudden Joint Pain? It Might Be Gout.

55.8 million
people worldwide had gout in 2020 – forecast to reach 95.8 million by 2050. Men are 3.26 times more likely to develop it than women (GBD 2021; The Lancet Rheumatology, 2024).

If you have ever been jolted awake by sudden, searing pain in your big toe – or any joint – that came out of nowhere, you may be experiencing the first signs of gout. It is one of the most painful forms of arthritis, and it is becoming more common in South Africa as diets, lifestyles, and chronic disease rates change.

The good news: gout is diagnosable with a simple blood test, and once confirmed, it is manageable. The bad news: many people suffer through repeated flare-ups for years without ever getting tested.

What is gout?

Gout is an inflammatory arthritis caused by the build-up of uric acid in the blood. When uric acid levels rise too high, sharp, needle-like crystals form in the joints – triggering intense pain, swelling, redness, and heat. While the big toe is the classic target, gout can strike the ankles, knees, elbows, wrists, and fingers (Hainer et al., 2014).

Uric acid is a waste product created when the body breaks down purines – substances found naturally in the body and in certain foods. Normally, the kidneys filter uric acid out through urine. But when the body produces too much, or the kidneys cannot clear enough, the excess accumulates and crystallises.

Warning signs of a gout attack

🔥
Sudden, severe joint pain

Strikes without warning, often at night. The pain is typically at its worst in the first 4 – 12 hours. The big toe is the most common site, but any joint can be affected.

🔴
Swelling, redness, and heat

The affected joint becomes red, swollen, and hot to the touch – as if it has been injured, even though you have done nothing to it.

😣
Lingering discomfort

Even after the worst pain fades, the joint may feel sore and stiff for days or weeks. Repeated flare-ups can cause lasting joint damage.

🔁
Recurring episodes

Without treatment, gout flare-ups tend to become more frequent, last longer, and affect more joints over time.

🪨
Tophi (advanced gout)

If uric acid remains elevated for years, hard lumps called tophi can form under the skin around joints, ears, and tendons – a sign of chronic tophaceous gout.

Do not wait for a second attack. The time between the first gout flare and chronic, joint-damaging gout varies from 3 to 42 years, with an average of 11 years. Early diagnosis and uric acid monitoring can prevent irreversible damage (BMC Rheumatology, 2024).

What triggers high uric acid?

🍖 High-purine foods

Red meat, organ meats (liver, kidney), shellfish, and anchovies are high in purines, which break down into uric acid. Braai culture and meat-heavy diets in South Africa are a significant contributor.

🍺 Alcohol, especially beer

Beer is particularly high in purines. Alcohol also impairs the kidneys' ability to excrete uric acid. Spirits and wine carry lower risk, but excess of any alcohol raises levels.

🥤 Sugary drinks and fructose

Soft drinks, fruit juices, and foods sweetened with high-fructose corn syrup increase uric acid production. South Africa has one of the highest sugary drink consumption rates in Africa.

⚖️ Obesity and metabolic syndrome

Excess weight increases uric acid production and reduces the kidneys' ability to clear it. Central obesity (waist circumference) is one of the strongest predictors.

🫘 Kidney dysfunction

The kidneys clear about 70% of uric acid. Even mild kidney impairment can cause levels to rise. In one SA study, hyperuricaemia prevalence reached 74% in patients with advanced kidney disease.

👨 Being male or postmenopausal

Men are 3 – 4 times more likely to develop gout. Women's risk rises significantly after menopause, when the protective effect of oestrogen on uric acid excretion declines.

Gout in South Africa

Gout has historically been considered a disease of affluence – the "disease of kings." But in modern South Africa, rising obesity rates, high alcohol consumption, increasing diabetes prevalence, and dietary changes are driving gout across all communities.

In affluent and urban communities

High-protein diets, regular alcohol consumption, sedentary lifestyles, and easy access to processed foods all contribute to elevated uric acid. Gout in this group is often well-managed once diagnosed – but many men dismiss recurring toe or joint pain as a sports injury or "just getting older" and never get tested. Private healthcare patients also have higher rates of chronic conditions like hypertension and metabolic syndrome, both of which are independently associated with gout.

In lower-income and rural communities

Access to laboratory testing for uric acid is limited in many public healthcare facilities. When a patient presents with acute joint pain, the diagnosis may default to septic arthritis or injury without uric acid levels being checked. Research from sub-Saharan Africa shows that two-thirds of gout patients present with oligoarticular or polyarticular disease, suggesting significant delays in diagnosis (BMC Rheumatology, 2024). Affordable staple foods high in purines (organ meats, tinned fish) combined with high rates of homebrew beer consumption contribute to elevated uric acid in these communities.

For travellers and foreign nationals

Changes in diet, alcohol intake, hydration, and activity levels during travel can trigger a gout flare-up – particularly after long flights where dehydration is common. If you experience sudden joint pain during your stay in South Africa, Epicentre offers walk-in uric acid testing at branches in Durban (Hillcrest), Cape Town (Observatory), and Johannesburg (Parktown North) – no doctor's referral needed, results in 2 – 5 working days.

How is gout diagnosed?

A blood test is the starting point. Gout is primarily diagnosed by measuring uric acid levels in the blood. Elevated uric acid (hyperuricaemia) does not guarantee gout, but combined with clinical symptoms, it strongly supports the diagnosis. Additional markers – CRP, ESR, kidney function – help assess the severity of inflammation and rule out kidney-related causes.

What Epicentre's Arthritis & Inflammation Profile tests

Arthritis & Inflammation Profile

Uric Acid CRP (C-Reactive Protein) ESR (Sed Rate) Full Blood Count (FBC) U&E + Creatinine (Kidney Function)

Results in 2 – 5 working days · No doctor's referral needed · Walk-in at any Epicentre branch · Fasting not required

This panel gives a comprehensive picture: uric acid confirms the gout diagnosis, CRP and ESR measure the severity of inflammation during a flare, FBC checks for infection or immune response, and kidney function tests identify whether impaired kidneys are contributing to uric acid build-up.

Reducing your gout risk

Lifestyle changes are the foundation of gout management – and they make a measurable difference:

  • Reduce high-purine foods – limit red meat, organ meats, and shellfish. Poultry and plant-based proteins are lower-risk alternatives
  • Cut back on alcohol, especially beer – beer has the strongest association with gout. If you drink, moderate wine carries the lowest risk
  • Avoid sugary drinks – soft drinks and fruit juices sweetened with fructose directly increase uric acid production
  • Stay hydrated – water helps the kidneys flush uric acid. Aim for 2 – 3 litres daily, more in hot climates
  • Maintain a healthy weight – even modest weight loss reduces uric acid levels. Crash diets should be avoided as rapid weight loss can temporarily increase uric acid
  • Monitor kidney function – if you have diabetes, hypertension, or a family history of kidney disease, regular kidney function tests can catch problems before they elevate uric acid
  • Get tested regularly – if you have had one gout attack, periodic uric acid testing helps track whether your levels are coming down
