High uric acid levels are common, but most people don’t realise that they have them until they experience a sudden and painful attack in a joint. The symptoms of high uric acid often go unnoticed for years, and when they do show up, people tend to attribute them to arthritis, an injury, or simply being tired. This delay has consequences because untreated high uric acid can cause damage to both the joints and kidneys. This article outlines the symptoms of high uric acid to watch for, explains the causes, describes how doctors check for it, and tells you when to see a doctor.
What Is High Uric Acid (Hyperuricaemia)?
High uric acid occurs when the blood contains more uric acid than the body can remove. This condition is known as hyperuricaemia. Uric acid is a waste product produced when the body breaks down purines, substances found in cells and many foods. The kidneys filter uric acid from the blood and excrete it through urine. Problems arise when the body produces too much uric acid, the kidneys remove too little, or both.
High uric acid levels can cause crystals to build up in the joints and kidneys. These crystals can cause pain and damage. Many people have high levels for years without symptoms, so doctors may discover them during a routine blood test.
Symptoms of High Uric Acid
The main symptoms associated with high uric acid include sudden joint pain, swelling, redness, stiffness, hard lumps under the skin, kidney stones, and pain in the lower back or side. Symptoms usually affect the joints and kidneys, although many people experience no symptoms at all.
Sudden Joint Pain
Severe joint pain can start suddenly, often at night, and reach its worst within a few hours. The pain may be so intense that even the touch of bedsheets feels uncomfortable.
Swelling and Redness
The affected joint may swell, become red, and feel warm. The surrounding skin can also look tight and shiny.
Limited Joint Movement
Pain and swelling can make the joint stiff and difficult to bend. An attack may settle over time, but repeated attacks can leave the joint stiff and damaged.
Hard Lumps Under the Skin
Long-standing high uric acid levels can lead to lumps known as tophi. These may appear on the fingers, elbows, ears, and toes. Tophi indicate deposits of uric acid crystals and may develop when uric acid remains high for a long time.
Recurrent Kidney Stones
Uric acid can crystallise in the kidneys and form stones. Warning signs include sharp pain in the side or back, blood in the urine, and pain while passing urine. If you have experienced repeated kidney stones, consult the best kidney stone hospital in Mumbai to assess the stones, their possible causes, and your uric acid levels.
Lower Back Pain
Lower back or side pain that occurs in sharp waves may indicate a kidney stone, especially when accompanied by nausea, vomiting, or blood in the urine.
Fatigue
Fatigue is a general symptom that can occur with many conditions. It is not a specific sign of high uric acid and should be assessed alongside other symptoms.
High Uric Acid Symptoms in Females
The symptoms of high uric acid in women are similar to those in men, but they may become more common after menopause. Before menopause, oestrogen helps the kidneys eliminate uric acid. After menopause, this protective effect decreases, which can contribute to higher uric acid levels.
Women may experience pain in their fingers, wrists, knees, or ankles. These symptoms can sometimes be mistaken for arthritis or age-related joint problems, delaying the correct diagnosis.
Conditions such as high blood pressure, kidney disease, diabetes, and obesity can increase the risk. Certain medicines, including diuretics, may also contribute to higher uric acid levels. Women experiencing repeated joint pain or swelling should discuss their symptoms and the need for testing with a doctor.
High Uric Acid Symptoms in Men
Symptoms in men are similar to those in women, although gout often develops earlier in men. A typical first sign is sudden, intense pain in the big toe, usually at night, accompanied by swelling, redness, and warmth.
If left untreated, attacks can recur and affect other joints. Heavy alcohol consumption, a diet high in red meat and shellfish, excess body weight, and kidney problems can increase the risk.
Where Symptoms Appear: Legs, Feet and Joints
Uric acid symptoms in the legs and feet most often affect the big toe, ankle, and knee. Gout attacks typically involve one joint at a time, particularly during the early stages.
| Body part | What you may notice |
|---|---|
| Big toe | Sudden, severe pain, swelling, redness, and warmth. The big toe is a common first site of gout. |
| Foot and heel | Pain and swelling across the top of the foot or around the heel. |
| Ankle | A swollen, stiff ankle that hurts when you put weight on it. |
| Knee | A warm, swollen knee that is painful and difficult to bend. |
| Fingers, wrists, and elbows | Pain and swelling, with hard lumps in long-standing cases. |
| Lower back and side | Sharp pain associated with kidney stones, sometimes with blood in the urine. |
What Causes High Uric Acid?
High uric acid occurs when the body produces too much uric acid, the kidneys remove too little, or both. Several factors may contribute:
- Food and drink: Red meat, organ meat, shellfish, sugary drinks, and alcohol, particularly beer, can increase uric acid levels or the risk of gout.
- Body weight: Excess weight can increase uric acid production and reduce its removal by the kidneys.
- Kidney function: When the kidneys do not work properly, they may struggle to remove uric acid.
- Medicines: Diuretics and low-dose aspirin can raise uric acid levels in some people. Do not stop prescribed medicines without medical advice.
- Health conditions: High blood pressure, diabetes, an underactive thyroid, and psoriasis may be associated with increased uric acid levels.
- Dehydration and crash diets: Not drinking enough water and following extreme diets may increase the risk of uric acid problems.
- Family history: Genetics can influence how the body processes and removes uric acid.
The causes vary from person to person. A doctor will consider your diet, medicines, kidney function, medical history, and family history when assessing your risk.
What Happens If Uric Acid Stays High?
If uric acid remains high, crystals may form in the joints and kidneys. Possible complications include:
- Repeated gout attacks affecting more joints.
- Permanent joint damage and stiffness.
- Tophi, or hard lumps under the skin.
- Kidney stones.
- Kidney complications in some cases.
Not everyone with high uric acid develops these problems. However, persistent high levels can increase the risk, especially in people with gout or kidney stones. Early assessment and appropriate treatment can help protect joint and kidney health.
How High Uric Acid Is Diagnosed
Doctors commonly use a serum uric acid test, a blood test that measures the amount of uric acid in the blood. The laboratory’s reference range helps interpret the result, but the number alone does not confirm or rule out gout.
Your doctor may also recommend:
- Joint fluid test: A small amount of fluid is removed from the affected joint and examined for uric acid crystals. This can help confirm gout.
- Urine uric acid test: This measures how much uric acid is being passed through urine in selected cases.
- Kidney function tests: These help assess how well the kidneys are working.
- Imaging: X-rays, ultrasound, or dual-energy CT scans may help identify joint damage, crystal deposits, or kidney stones.
Uric acid levels can sometimes be normal during an acute gout attack. A doctor may therefore repeat the test after the attack settles if gout is still suspected.
How to Reduce High Uric Acid
High uric acid can often be managed through dietary changes, adequate fluid intake, gradual weight management, and medicines when needed. Treatment depends on the uric acid level, symptoms, kidney health, and medical history.
Helpful steps include:
- Drink enough water throughout the day, unless your doctor has advised fluid restriction.
- Limit alcohol, especially beer.
- Reduce your intake of red meat, organ meat, and shellfish.
- Avoid or limit sugary drinks.
- Lose weight gradually if needed. Avoid crash diets and extreme fasting.
- Include vegetables, whole grains, and low-fat dairy products in a balanced diet.
- Take medicines only as prescribed. Doctors may use anti-inflammatory medicines to manage gout attacks and uric acid-lowering medicines for long-term control.
Do not start or stop medication on your own. Diet and lifestyle changes can help, but some people need long-term medical treatment to prevent gout attacks and complications.
When to See a Doctor
See a doctor if you experience sudden, severe joint pain; a joint that is swollen, red, and warm; repeated joint attacks; or a high uric acid result on a blood test.
Seek urgent medical care if you have:
- A hot, swollen joint accompanied by fever, as this could indicate a joint infection.
- Severe side or back pain with vomiting or blood in the urine.
- Very little or no urine.
A rheumatologist treats gout and other joint problems associated with high uric acid, while a nephrologist treats kidney problems. If your symptoms suggest a kidney problem, such as repeated stones, side pain, or abnormal kidney function tests, consult a kidney specialist in Mumbai.
Frequently Asked Questions
What happens when uric acid increases?
When uric acid levels rise, excess uric acid may form crystals in the joints and kidneys. These crystals can cause gout attacks and kidney stones, and persistent problems may damage the joints. Many people have no symptoms initially, so a blood test and medical assessment can help identify high levels.
What if uric acid is high but I have no symptoms?
A high uric acid level without symptoms does not automatically mean that medication is needed. Your doctor may review your kidney function, medicines, medical history, and other risk factors before recommending lifestyle changes, monitoring, or treatment.
What are uric acid symptoms in the legs?
Symptoms may include sudden pain, swelling, redness, and warmth in the big toe, ankle, foot, or knee. The affected joint may feel stiff and hurt when touched or when you put weight on it. Other conditions can cause similar symptoms, so medical assessment is important.
Is high uric acid curable?
High uric acid can often be controlled with lifestyle changes and, when necessary, medication. Some people need long-term treatment to maintain healthy levels and prevent gout attacks. The treatment plan depends on the cause and whether complications have developed.
Can high uric acid damage the kidneys?
High uric acid can contribute to uric acid kidney stones. Kidney disease can also reduce the body’s ability to remove uric acid, so doctors may assess kidney function when evaluating someone with high levels or recurrent stones.
Do uric acid attacks hurt more at night?
Gout attacks often begin at night or in the early morning, and pain may become severe within hours. Sudden joint pain, swelling, and redness should be assessed by a doctor, regardless of the time of day.
Which foods raise uric acid?
Red meat, organ meat, shellfish, sugary drinks, and alcohol, particularly beer, may increase uric acid levels or the risk of gout. Diet is only one factor; genetics, body weight, medicines, and kidney function also matter.
Which doctor treats high uric acid?
A rheumatologist treats gout and related joint problems, while a nephrologist treats kidney complications. You can also start with a general physician, who can arrange appropriate tests and refer you to a specialist if necessary.
