Uric acid is a natural waste product formed when the body breaks down purines - that are substances found in certain foods and naturally present in the body. While uric acid normally dissolves in the blood and exits through urine, imbalances can occur when production increases or elimination decreases. Monitoring uric acid levels is important because persistently high levels may lead to several health issues such as gout and kidney stones, while unusually low levels can indicate other underlying health conditions. Keeping track of uric acid levels helps support joint health, kidney function, and overall well-being. In this article, we’ll explain everything you need to know about uric acid, including the normal uric acid range, symptoms and causes of high and low levels, testing methods, management tips, and when to consult a doctor.

Uric Acid Normal Range

Uric acid levels can vary based on age, gender, and certain health conditions. Understanding what is considered a normal range helps in identifying potential health concerns early. The typical uric acid levels are as follows:

• Adult male: 4.0–8.5 mg/dL (0.24–0.51 mmol/L)
• Adult female: 2.7–7.3 mg/dL (0.16–0.43 mmol/L)
• Elderly: Slightly higher values may occur due to age-related changes
• Child: 2.5–5.5 mg/dL (0.12–0.32 mmol/L)
• Newborn: 2.0–6.2 mg/dL

What do abnormal levels mean?

• High uric acid (hyperuricemia): May be linked to gout, kidney stones, or other metabolic issues.

• Low uric acid (hypouricemia): Less common and usually associated with certain genetic or liver-related conditions.

Note: These reference ranges provide a general guideline, but levels may differ slightly depending on the laboratory. Consistently high or low values should be reviewed by a doctor to determine any underlying issues.

Causes of High and Low Uric Acid Levels

There are several factors that can influence uric acid levels, leading to either an increase or a decrease. Understanding these causes helps in managing and preventing related health concerns.

Common causes of high uric acid levels include

• Dietary habits: Consuming large amounts of red meat, seafood, or alcohol can raise uric acid levels.
• Medical conditions: Chronic kidney disease, diabetes, obesity, and metabolic syndrome can lead to elevated uric acid.
• Medications and lifestyle factors: Certain diuretics, chemotherapy drugs, dehydration, and a sedentary lifestyle may also contribute.

Common causes of low uric acid levels include

• Rare genetic disorders: Conditions that affect purine metabolism can lead to unusually low uric acid.
• Liver disease: Some liver conditions reduce uric acid production.
• Overhydration or medications: Excessive fluid intake or specific medications may dilute or lower uric acid levels.

Symptoms of High and Low Uric Acid

Uric acid imbalances can affect the body in different ways. High uric acid levels may lead to noticeable symptoms, particularly when complications like gout or kidney stones develop. In contrast, low uric acid levels are usually symptom-free.

High Uric Acid Symptoms

These symptoms generally appear when excess uric acid causes gout or kidney stones.

Gout-related symptoms:

• Swollen, tender, or painful joints (commonly affecting the big toe)
• Warmth and redness around the affected joints
• Shiny or discoloured skin over the joint area

Kidney stone-related symptoms:

• Sharp pain in the back, side, or lower abdomen
• Urine that appears discoloured, bloody, or has a strong odour
• Frequent urge to urinate or difficulty passing urine
• Nausea and vomiting, especially if a stone blocks the urinary tract

Low Uric Acid Symptoms

Low uric acid levels (hypouricemia) typically do not cause noticeable symptoms and are often discovered incidentally during routine blood tests. However, in rare cases linked to certain genetic conditions, low uric acid may be associated with:

• Muscle weakness
• Other metabolic concerns

Most individuals with low uric acid do not experience health problems directly related to the low levels.

Complications of Untreated High Uric Acid

When high uric acid levels are left unmanaged over time, they can lead to serious health complications that affect joints, kidneys, and overall well-being.

Key complications include:

• Gout: Excess uric acid can crystallise in the joints, leading to recurrent attacks of intense pain, swelling, and inflammation. Over time, this may cause joint damage and deformities.
• Tophi formation: Hard lumps of uric acid crystals, known as tophi, can develop under the skin around joints or other tissues, causing discomfort and limited mobility.
• Kidney stones: High uric acid increases the risk of stone formation in the kidneys, which can result in severe pain, urinary problems, and potential kidney damage.
• Chronic kidney disease: Persistently elevated levels may impair kidney function over the long term, contributing to chronic kidney disease.
• Cardiovascular risks: Studies suggest that high uric acid may be linked to increased risks of hypertension, heart disease, and stroke, though more research is ongoing.

How Uric Acid is Measured and Diagnosed

Testing uric acid levels is straightforward and helps detect imbalances early. Doctors may recommend different tests based on symptoms and health history.

The main methods include:

• Uric acid blood test: Measures the level of uric acid circulating in the blood.
• Uric acid urine test: Assesses how much uric acid is excreted over a 24-hour period, useful for understanding kidney function.
• Joint aspiration test: In cases of suspected gout, a small sample of fluid is taken from an affected joint to check for uric acid crystals.

Test preparation tips:

• Fasting may be recommended for some tests.
• Avoid alcohol and purine-rich foods before testing, if advised.
• Inform the doctor about any medications, as certain drugs can affect results.

Treatment for High and Low Uric Acid Levels

Treatment for abnormal uric acid levels depends on whether levels are elevated or unusually low, as well as the underlying cause.

For high uric acid levels (hyperuricemia):

• Medications: Doctors may prescribe drugs such as allopurinol, febuxostat, or probenecid to lower uric acid production or increase its excretion.
• Pain management: Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids may be used during gout flare-ups to relieve joint pain and inflammation.
• Lifestyle changes: Diet modification, weight management, and increased hydration are essential alongside medical treatment.

For low uric acid levels (hypouricemia):

• Treatment focuses on managing any underlying condition, such as addressing liver disorders or adjusting medications that may be affecting uric acid levels.
• Regular monitoring is usually recommended, as low uric acid levels rarely require direct treatment unless associated with another medical issue.

How to Manage and Reduce Uric Acid Levels

Managing uric acid levels often involves a combination of lifestyle changes and, when necessary, medical treatment. Small adjustments in daily habits can make a significant difference in preventing flare-ups and complications.

Helpful tips to manage and reduce uric acid levels include:

• Limit purine-rich foods: Reduce intake of red meat (such as beef, lamb, and pork), organ meats (such as liver, kidneys, and sweetbreads), shellfish (such as shrimp, crab, and lobster), and certain fish (such as anchovies, sardines, trout, herring, and haddock). Processed meats like bacon and sausages should also be limited.
• Cut down on sugar: Avoid sugary drinks and foods high in fructose, as these can contribute to higher uric acid levels.
• Stay hydrated: Drinking plenty of water helps flush out uric acid through urine.
• Avoid alcohol: Alcohol, especially beer and spirits, can increase uric acid production.
• Consider moderate coffee intake: Some studies suggest that drinking coffee in moderation may lower uric acid levels.

When to See a Doctor

While occasional fluctuations in uric acid levels are common, certain signs and symptoms should prompt a medical consultation to prevent complications. It is important to see a doctor if any of the following occur:

• Persistent joint pain, swelling, or redness, especially in the big toe or other joints
• Recurrent kidney stones or unexplained back or side pain
• Abnormal uric acid test results combined with symptoms such as fatigue, nausea, or changes in urine output
