Gout: Symptoms, Causes, Food Triggers and Treatment

Gout: Symptoms, Causes, Food Triggers and Treatment

Gout is a type of inflammatory arthritis that causes sudden, severe pain, swelling, redness and heat in a joint, most often the big toe. It happens when too much uric acid builds up in your blood and forms sharp crystals in and around the joint. Flares can be treated quickly with anti-inflammatory medicine, and long-term uric acid lowering treatment, along with changes to food and drink, can stop attacks from coming back.

This article is for general information and is not medical advice.

Key takeaways

  • Gout is caused by excess uric acid in the blood, which can form needle-shaped crystals in joints and trigger intense pain and swelling.
  • Attacks often start suddenly at night, usually in one joint, and the pain tends to peak within the first 8 to 12 hours.
  • Common triggers include alcohol (especially beer), sugary drinks, red and organ meats, certain seafood, dehydration and very large meals.
  • Flares are treated with NSAIDs, colchicine or corticosteroids; long-term medicines such as allopurinol lower uric acid to prevent future attacks.
  • Treatment usually aims for a blood uric acid level of 6 mg/dL or lower, and the medicine is taken regularly even when you feel fine.

What are the symptoms of gout?

The classic sign of gout is sudden, intense pain in a single joint, with the skin over it hot, swollen and red. The big toe is the most common spot, but gout can also affect the feet, ankles, knees, hands, wrists and elbows.

According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), the pain often begins at night and can be bad enough to wake you. The Mayo Clinic notes that pain is usually worst in the first 8 to 12 hours, and some soreness can linger for days or weeks after.

A flare (also called an attack) is a period of active symptoms. NIAMS says flares usually last about a week or two. Between flares you may feel completely normal; doctors call this symptom-free stretch interval gout.

If gout goes untreated, the CDC explains that flares may become more frequent and last longer. Over time, lumps of crystals called tophi can form under the skin, often on the fingers, elbows, ears, feet or Achilles tendons. Tophi may start out painless but can become painful and damage joints.

What causes gout and who is at risk?

Gout is caused by hyperuricemia, which simply means having too much uric acid (urate) in your blood for a long time. When levels stay high, urate can crystallize in the joints and set off inflammation.

Your body makes uric acid when it breaks down purines, natural substances found in your own cells and in many foods. Normally your kidneys filter uric acid out into your urine. Gout develops when your body makes too much uric acid, your kidneys remove too little, or both.

High uric acid does not always lead to gout, but these factors raise your risk, based on NIAMS, the CDC and the Mayo Clinic:

  • Sex and age: gout is more common in men, especially with age. Risk in women rises after menopause.
  • Family history: gout often runs in families.
  • Body weight: overweight and obesity raise uric acid levels.
  • Health conditions: high blood pressure, diabetes, insulin resistance, metabolic syndrome, heart failure and chronic kidney disease.
  • Medicines: diuretics (water pills), low-dose aspirin, ACE inhibitors, beta blockers, large doses of niacin and some transplant drugs such as cyclosporine.
  • Diet and drinks: alcohol, sugar-sweetened drinks and a diet heavy in purine-rich animal foods.
  • Recent surgery or injury, which can sometimes set off an attack.

Because high blood pressure and gout so often travel together, it helps to understand what your blood pressure numbers mean and to review any water pills with your doctor if you start getting flares.

Which foods and drinks trigger gout?

The biggest dietary triggers are alcohol (especially beer), sugary drinks sweetened with fructose, red and organ meats, and certain seafood. Large meals, heavy drinking sessions and dehydration can also bring on a flare.

The table below summarizes what major health bodies suggest limiting and what to favor instead.

CategoryLimit or avoidBetter choices
AlcoholBeer (including nonalcoholic beer, per the Mayo Clinic) and hard liquorAlcohol-free days each week; water or unsweetened drinks
DrinksSodas and drinks with high fructose corn syrup; fruit juice and concentrated juicesPlenty of water throughout the day
MeatRed meat, organ meats such as liver, gravies and meat-based soupsSmaller portions of lean protein; more plant-based meals
SeafoodAnchovies, sardines, mussels, scallops, trout, tuna and other shellfishOccasional smaller servings rather than large ones
Snacks and sweetsSugary foods and snacks made with high fructose corn syrupWhole, minimally processed foods
Eating patternVery large meals and crash dietsRegular, moderate meals and steady weight loss if needed

On alcohol, the NHS advises having alcohol-free days every week and not drinking more than 14 units a week. If you want the wider picture, our guide on alcohol and long-term health explains why cutting back helps far beyond your joints.

Other triggers listed by the NHS include an illness with a high temperature, joint injury, dehydration and certain medicines. Keeping well hydrated is simple and matters; see how much water to drink each day for practical targets.

How is gout diagnosed?

A doctor diagnoses gout from your symptoms, a physical exam and tests, ideally during a flare when crystals are easiest to find. The most definitive test is looking at fluid from the swollen joint under a microscope for urate crystals.

Tests your doctor may use, according to the Mayo Clinic and the American College of Rheumatology:

  • Joint fluid test: a thin needle draws fluid from the joint, which is checked for crystals.
  • Blood test: measures uric acid. A high level supports the diagnosis, but it does not prove gout on its own.
  • X-ray: helps rule out other causes of joint swelling and can show joint changes from long-standing gout.
  • Ultrasound: can detect urate crystals in joint cartilage or tophi.
  • Dual-energy CT (DECT): a specialized scan that shows urate crystals in and around joints.

Your doctor will also ask about your diet, alcohol intake and medicines. If the picture is unclear, the NHS says a GP may refer you to a rheumatologist, a doctor who specializes in arthritis and joint conditions.

How is a gout flare treated?

A gout flare is treated with medicine that calms inflammation, and it works best when started as early as possible. The three main options are NSAIDs, colchicine and corticosteroids.

  • NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen, naproxen, indomethacin or celecoxib. The Mayo Clinic warns that overuse can cause stomach pain, bleeding and ulcers.
  • Colchicine, which the Mayo Clinic says works best when taken within 24 hours of symptoms starting. It can cause nausea, vomiting and loose stools.
  • Corticosteroids such as prednisone, taken as tablets or injected directly into the joint. Side effects can include mood changes, high blood sugar and raised blood pressure.

Alongside medicine, these steps from the NHS can ease a flare at home:

  1. Take your prescribed flare medicine as soon as you feel an attack starting.
  2. Rest the joint and raise the limb.
  3. Apply an ice pack (or frozen peas wrapped in a towel) for up to 20 minutes at a time.
  4. Drink plenty of water unless your doctor has told you otherwise.
  5. Keep bedclothes off the joint at night and avoid putting pressure on it.

How does long-term urate-lowering treatment work?

Urate-lowering therapy means taking a daily medicine that reduces uric acid in your blood so crystals slowly dissolve and new ones stop forming. The American College of Rheumatology says treatment aims for a uric acid level of 6 mg/dL or lower.

The NHS notes this kind of medicine is usually offered if you have frequent attacks or high uric acid levels. The main options are:

  • Allopurinol and febuxostat, which reduce how much uric acid your body makes. The Mayo Clinic notes febuxostat may raise the risk of heart-related death, so it is not a first choice for everyone.
  • Probenecid, which helps your kidneys remove more uric acid. It can cause kidney stones in some people.
  • Pegloticase, given through a vein, for severe gout that has not responded to other treatment.

Two points often surprise people. First, starting urate-lowering medicine can briefly trigger flares, so your doctor may prescribe low-dose colchicine, an NSAID or a low-dose steroid to prevent them. Second, the NHS stresses that you need to keep taking the medicine regularly, even when you have no symptoms. Stopping usually lets uric acid climb back up.

If you also have kidney disease, your doctor will choose and dose these medicines carefully. Our article on simple habits for healthy kidneys covers everyday steps that support kidney function.

Can diet and lifestyle changes help control gout?

Yes. Lifestyle changes lower your risk of flares and support medicine, though for many people with frequent attacks they are not enough on their own. The core steps are limiting alcohol and sugary drinks, cutting back on high-purine foods, staying hydrated, reaching a healthy weight and staying active.

  • Eat more plants: build meals around vegetables, whole grains and legumes. A plant-based eating pattern can also help protect your kidneys, which clear uric acid.
  • Lose weight gradually: the NHS advises losing excess weight but avoiding crash diets, which can trigger flares.
  • Move regularly: the CDC recommends at least 150 minutes a week of moderate activity. The Mayo Clinic suggests low-impact choices such as walking, cycling and swimming, which are easier on sore joints.
  • Quit smoking: the NHS lists stopping smoking as part of gout prevention.
  • Ask before taking supplements: the NHS suggests asking a GP whether vitamin C supplements are right for you rather than starting them on your own.

Common mistakes people make with gout

  • Stopping urate-lowering medicine once flares stop. The absence of attacks means the medicine is working, not that you no longer need it.
  • Waiting too long to treat a flare. Flare medicines work best when started early, so keep a supply on hand if your doctor agrees.
  • Relying on diet alone. Food changes help, but many people still need medicine to reach their uric acid target.
  • Switching to nonalcoholic beer and assuming it is safe. The Mayo Clinic advises limiting beer without alcohol too.
  • Crash dieting. Rapid weight loss and fasting can trigger flares; slow, steady loss is better.
  • Ignoring other conditions. Gout is linked with high blood pressure, kidney disease and diabetes, so regular checkups matter.

When to see a doctor

  • You have sudden, severe joint pain for the first time.
  • A hot, swollen joint comes with a fever, chills or shivering, which can signal an infection inside the joint and needs urgent care.
  • You feel sick, cannot eat or the pain keeps getting worse despite treatment.
  • Your usual gout treatment is no longer working.
  • You notice hard lumps under the skin on your fingers, elbows, ears or feet.
  • You have flank pain, blood in your urine or other signs of a kidney stone.
  • You develop a rash, fever or other new symptoms after starting a urate-lowering medicine.

Frequently asked questions

How long does a gout attack last?

Most gout flares last about one to two weeks. Pain usually peaks in the first 8 to 12 hours, and treating the attack early can shorten it.

Can gout go away on its own?

A single flare will usually settle, but the underlying high uric acid does not go away without changes and often medicine. Untreated gout tends to cause more frequent flares, tophi and joint damage over time.

Is gout only caused by diet?

No. Genes, kidney function, body weight, other health conditions and some medicines all play a role. Diet and alcohol are important triggers, but many people with gout eat fairly well.

Do I have to take gout medicine for life?

Many people stay on urate-lowering medicine long term because stopping often lets uric acid rise again. Talk with your doctor before making any change to your dose.

What to do next

If you think you have had a gout attack, book an appointment, ideally while the joint is still swollen, so your doctor can test it. Ask for a uric acid blood test and a review of your current medicines. If you have had more than one flare, ask whether urate-lowering therapy is right for you and what your target level should be.

At home, start with the easy wins: drink more water, cut back on beer and sugary drinks, and plan more plant-heavy meals. An anti-inflammatory diet with a sample meal plan can give you a practical place to begin.

Top 10 Exercises to Help You Sleep Longer and Better

Image
The best exercises for sleep are the ones you'll do most days: brisk walking, yoga, swimming, cycling, strength training and gentle evening stretching all have research linking them to falling asleep faster and sleeping more deeply. Moderate activity can fit almost any time of day. Hard, sweaty workouts are usually best kept away from the last couple of hours before bed. This guide is for you if you lie awake at night, wake up unrefreshed, or want a drug-free way to sleep better, and you'd like to know which kind of movement to try first. Key takeaways Regular activity over weeks matters more than any single workout. Expect gradual change, not an overnight fix. Morning walks outdoors pair movement with daylight, which helps set your body clock. Slow, breath-focused practices such as yoga, tai chi and stretching are the best fit for evenings. Save high-intensity workouts for morning or early afternoon if late sessions keep you up. Exercise helps most sleep problems but...

Muscle Gain Diet: What Actually Works, Kept Simple

Image
To build muscle, most people who lift regularly need about 1.4 to 2.0 grams of protein per kilogram of body weight a day, spread over meals of roughly 20 to 40 grams each, plus enough total food to fuel training. Add consistent strength training and decent sleep, and that covers most of the results. Everything else is fine-tuning. This guide is for anyone who has started lifting and feels buried in conflicting advice about meal timing, shakes and supplement stacks. Here's the short, evidence-based version. Key takeaways The International Society of Sports Nutrition (ISSN) says 1.4 to 2.0 g of protein per kg per day is enough for most exercising people building muscle. Spread protein across the day, about 20 to 40 g per meal, every 3 to 4 hours. Exact timing around your workout matters less than total daily intake. Eating before or after training both work. Creatine monohydrate is the best-supported supplement. Protein powder is a convenience, not a requirement. If you...

Plant Protein Powder for Acne-Prone Skin: What to Know

Image
If your skin broke out after you started whey protein shakes, switching to a plant-based protein powder is a reasonable experiment. Cow's milk has been linked with acne, and case reports describe acne flares that cleared after whey was stopped. A pea protein powder can support muscle growth, and one trial found results similar to whey. This guide is for people who lift or train and want to keep building muscle without guessing about their skin. It covers what the evidence does and doesn't show, how to choose a powder and how to run a fair test. Key takeaways The milk link is real but not fully explained: the American Academy of Dermatology (AAD) says studies link cow's milk with acne, though the reason isn't clear. Whey evidence is limited: it comes mostly from small case reports and observational studies, not large trials. Pea protein can build muscle: in a 12-week trial, pea and whey produced similar gains in muscle thickness. Sugar matters too: high-gly...

Can Pinworms Last for Years? Why Infections Keep Coming Back

Image
No, a single pinworm can't live in your body for years. Adult worms live for only a few weeks. What makes an infection seem to last for months, or even years, is reinfection: eggs get swallowed again and start a new cycle before the old one ends. Break that cycle and the infection clears. This is for parents who've treated a child, seen the itching come back a few weeks later, and started to wonder whether something more serious is going on. Key takeaways Pinworms live for weeks, not years. Long-running "infections" are almost always repeated reinfections. Treatment is two doses of medicine, two weeks apart, because the medicine kills worms but not eggs. Everyone in the household needs treating at the same time, even people with no symptoms. Eggs can survive on bedding, clothes and surfaces for around two to three weeks, so cleaning matters as much as medicine. Pinworm rarely causes serious harm, but see a doctor for babies under 2, during pregnancy, or if t...

Calorie Deficit and Insomnia: Why Dieting Keeps You Awake

Image
Yes, a calorie deficit can cause insomnia. Eating less than you burn lowers overnight blood sugar, raises the hunger hormone ghrelin and nudges cortisol up, and together those signals can wake you at 2 or 3 a.m. The bigger and faster the deficit, the more likely your sleep suffers. This guide is for anyone who started a diet and suddenly sleeps worse. You'll learn how to recognize diet-related sleep trouble, and how to adjust your plan so you keep losing fat without lying awake staring at the ceiling. Key takeaways Diet-related sleep trouble usually looks like waking in the second half of the night, not trouble falling asleep. Large, fast deficits disrupt sleep more than small, steady ones. Keeping protein adequate and saving some carbohydrate for the evening often helps. Poor sleep makes dieting harder: it raises hunger and can shift weight loss away from fat and toward muscle. Loud snoring, gasping, or insomnia that started before the diet needs a medical check, not a ...

Why Am I Losing Muscle Mass? Causes, Signs and Fixes

Image
Most unexplained muscle loss comes from using your muscles less, getting older, or eating too little protein and energy. Less often, it's a sign of nerve damage, a hormone problem or another illness. The good news is that the common causes respond well to regular strength training and enough protein at each meal. Maybe your legs look thinner after a few months at a desk job, or the stairs feel harder than they did last year. This guide is for anyone who has noticed that change and wants to know what's behind it and what to do next. Key takeaways Disuse is the most common cause: muscles shrink when they aren't worked regularly, and this type can often be reversed with exercise and better nutrition. Age plays a part: Cleveland Clinic says age-related muscle loss (sarcopenia) starts in your 30s or 40s and speeds up between ages 65 and 80. Strength training is the main fix: adults should do muscle-strengthening activity on at least 2 days a week, according to the CD...

No-Sugar Diet: How to Cut Added Sugar Step by Step

Image
A no-sugar diet means cutting added sugars, not the natural sugar in whole fruit, vegetables and plain dairy. You drop soda, sweets and sweetened snacks first, then hunt down hidden sugar in sauces, bread, yogurt and cereal. Most people get through the hardest cravings within one to two weeks. It sounds simple until you start reading labels and find sugar in pasta sauce, salad dressing and "healthy" granola. This guide is for anyone who wants to cut back without a miserable, all-or-nothing approach that collapses by week two. Key takeaways The target is added and free sugars: table sugar, syrups, honey, fruit juice and sweeteners added to processed food. The WHO advises keeping free sugars under 10% of daily calories, with extra benefit below 5%, about 25 grams or 6 teaspoons a day. The CDC reports that US adults average about 17 teaspoons of added sugar a day. Expect cravings, irritability or low energy for the first few days; they usually ease within one to two we...

Fruits That Help Reduce Cholesterol and What to Avoid

Image
Avocado, berries, oranges and an apple, fruits that fit a cholesterol-friendly diet Fruits that are rich in soluble fiber, such as apples, pears, oranges, bananas and prunes, can help lower LDL ("bad") cholesterol as part of an overall heart-healthy diet. Avocado can help too when it replaces saturated fat. Fruit alone won't fix high cholesterol, but it's one of the easiest changes to stick with. This guide is for anyone who's just seen a high cholesterol result and wants to know what to put on the plate, and what to watch out for, especially if you take a statin. Key takeaways MedlinePlus lists apples, bananas, oranges, pears and prunes as fruit sources of soluble fiber, which helps lower cholesterol. The suggested target is 10 to 25 grams of soluble fiber a day, from fruit, oats, beans and other foods. In a small controlled study, a moderate-fat diet with one avocado a day lowered LDL more than a similar diet without avocado. Grapefruit, Seville ora...

Soursop Benefits and Risks: Fruit, Leaves and Tea

Image
Soursop fruit is a healthy, fibre-rich tropical fruit that's safe to enjoy in normal amounts. Its leaves and tea have traditional uses with some early lab and animal evidence, but no human trials show soursop treats or cures cancer. High-dose leaf extracts and supplements also raise real concerns about nerve damage, so they deserve caution. This is for anyone who enjoys soursop, has been told to drink the leaf tea for a health problem, or has seen posts claiming it beats chemotherapy and wants a straight answer. Key takeaways The fruit pulp offers fibre, vitamin C and potassium, and fits well in a varied diet. Soursop extracts kill some cancer cells in lab dishes, but that hasn't been shown in people. No reputable cancer organisation supports it as a treatment. Compounds in soursop, especially concentrated in leaves, seeds and bark, can harm nerve cells. Heavy long-term use has been linked to Parkinson-like symptoms. Occasional leaf tea is different from daily concentr...

Gastroparesis and Hashimoto's Diet: Gentle Gluten-Free Meals

Image
If you have both gastroparesis and Hashimoto's, the meals that tend to work best are small, soft, well-cooked, low in fat and fiber, and built around lean protein and simple starches like white rice, peeled potatoes and cooked squash. Many people with Hashimoto's also choose gluten-free versions, especially if celiac disease or gluten sensitivity has been found. This guide is for anyone trying to plan meals around both conditions at once, and for family members who cook for them. The two sets of advice often seem to pull in opposite directions, but there is more overlap than it first looks. Key takeaways Gastroparesis eating advice centers on low fat, low fiber, soft textures and five or six small meals a day. Hashimoto's has no single proven diet. Gluten-free eating matters most if you also have celiac disease, which is more common alongside Hashimoto's. Lean proteins (eggs, white fish, chicken, turkey) and peeled, well-cooked starches fit both sets of needs. ...
