What causes high uric acid levels?

This article is written by mr.hotsia, a curious traveler who has spent years walking through clinics, tea shops and hospital corridors across Thailand, Laos, Vietnam, Cambodia, Myanmar, India and many other Asian countries.

In many of these places I hear the same sentences again and again

“My blood test says uric acid is high. Why”
“I already stopped eating meat for a week. Why is it still high”
“Is it from my food, my kidneys or my parents”

So the clear question is

What actually causes high uric acid levels inside the body

This explanation uses safe, lifestyle focused wording. It is not medical advice or treatment. It is meant to help you understand what is going on so you can talk more clearly with your doctor and choose habits that may help support healthier uric acid levels.

1. Quick overview: how uric acid works

Uric acid is a normal waste product. It is created when the body breaks down substances called purines that come from

Normal turnover of your own cells
Food and drinks you consume

Normally

Uric acid goes into the blood
The kidneys filter it
Most of it leaves in the urine

If this system stays in balance, uric acid remains in a healthy range.

High uric acid levels, called hyperuricemia, happen when

The body produces too much uric acid, or
The kidneys remove too little, or
A bit of both

Now let us unpack the main causes one by one.

2. Genetics: the “factory setting” you are born with

On my travels I often see two friends who

Eat the same food
Drink the same drinks
Live similar lifestyles

One has high uric acid and gout, the other is completely fine.

The big invisible difference is genetics.

Some people are born with kidneys and enzymes that

Clear uric acid efficiently
Keep blood levels lower

Others are born with systems that

Clear uric acid more slowly
Keep higher baseline levels
Form crystals more easily

So genes can strongly influence

How much uric acid your body tends to keep
How sensitive you are to diet and lifestyle

You cannot change your genes, but knowing this can motivate you to pay more attention to the controllable factors.

3. Kidney function: the main “exit door” for uric acid

Your kidneys are like filters. They decide how much uric acid leaves your body each day.

If your kidneys are

Healthy and strong
- Uric acid is more likely to stay in a safe range

If your kidneys are

Weaker
Affected by long term conditions
Under stress from medicines or illness

they may remove less uric acid.

This can happen with

Chronic kidney disease
Long standing high blood pressure
Diabetes and metabolic problems
Some infections or toxic exposures

When removal is slower, uric acid accumulates in the blood.

So in many people, high uric acid is mainly a kidney handling issue, not only about what they ate last night.

4. Lifestyle and diet: daily choices that push levels up

Food and drink do not act alone, but they can push uric acid higher, especially if genetics and kidneys are already not perfect.

a) High purine foods in large and frequent amounts

Foods that are higher in purines include

Organ meats
- Liver
- Kidney
- Some types of offal
Certain seafoods
- Anchovies
- Sardines
- Some shellfish
Large frequent portions of rich red meat

If someone has

Good genetic handling
Strong kidneys

they may tolerate these foods better.

If someone already has

Slower uric acid removal
Family history of gout

these foods in large and repeated amounts can slowly raise uric acid.

b) Alcohol, especially beer and spirits

Alcohol can raise uric acid by

Increasing its production in the body
Reducing kidney excretion

Beer also contains purines from yeast. Heavy and frequent drinking, especially beer and spirits, is a classic factor seen in many gout and high uric acid stories across Asia.

c) Sugary drinks and high fructose intake

Drinks high in

Sugar
High fructose corn syrup

can increase uric acid production during their metabolism.

Regular use of

Sweet soft drinks
Energy drinks
Very sweet bottled teas or juices

can add to the uric acid load, especially in people already at risk.

d) Big feasts and “festival style” eating

A single feast will not permanently damage everyone, but in people with high baseline risk, patterns like

Repeated very heavy meals
Lots of meat, organs, alcohol and sugary desserts together

can temporarily push uric acid very high and may trigger flares in those prone to gout.

5. Body weight and metabolism: the slow pressure on uric acid

In many clinics I visit, patients with high uric acid often also have

Increased waist size
Higher blood pressure
Higher blood sugar or prediabetes
High triglycerides or cholesterol

This cluster is often called metabolic syndrome.

Extra body fat and metabolic imbalance can

Increase production of uric acid
Reduce the kidneys’ ability to clear it
Increase general inflammation in the body

Over time this combination can steadily push uric acid levels upward.

Gentle, sustainable weight loss in people with overweight, together with better metabolic control, may help support lower uric acid levels and reduce stress on joints and kidneys.

6. Medical conditions that can raise uric acid

Several health issues are often linked to higher uric acid levels

Chronic kidney disease
Kidneys filter less uric acid.
High blood pressure and heart conditions
May affect both kidney blood flow and medication choices.
Diabetes and insulin resistance
Change how uric acid and kidney function interact.
Blood cancers and rapid cell turnover conditions
Increased cell breakdown can produce more purines and uric acid.
Psoriasis and some skin or blood disorders
High cell turnover can have a similar effect.

In these situations, high uric acid is often part of a wider medical picture rather than an isolated problem.

7. Medicines that can push uric acid higher

Some medicines affect uric acid handling. Only a doctor can decide which ones are relevant in your case, but commonly discussed examples include

Certain diuretics
- Water tablets used for blood pressure or heart failure
Some drugs for high blood pressure
- A few older types can reduce uric acid excretion
Low dose aspirin in some people
Some medicines used in
- Cancer treatment
- Immune suppression
- Tuberculosis therapy

This does not mean you should ever stop them by yourself. It means that if your uric acid is high, your doctor may review your medications and adjust when possible.

8. Situations that cause a temporary rise in uric acid

Even people with stable health can experience temporary spikes in uric acid due to

Dehydration
- Less water in the body makes uric acid more concentrated in the blood
Crash dieting or fasting
- Rapid breakdown of internal tissues increases purine load
Severe illness, surgery or trauma
- The body’s stress response and tissue breakdown can raise uric acid

These conditions can provoke gout attacks in people already prone to high uric acid, even if their usual numbers are borderline.

9. Overproduction vs under excretion: which is more common

Although we often talk about food, in everyday life most people with high uric acid have a problem mainly with under excretion

Their kidneys do not remove uric acid efficiently enough
Diet and metabolism push more into the system
Levels rise gently over years

True massive overproduction due to rare enzyme disorders or extreme cell breakdown exists, but is less common in the general population.

So for many people, the real story is

“My body is not great at getting rid of uric acid, and my lifestyle slowly overloads the system.”

rather than

“It is only from one type of food.”

10. Lifestyle factors that may help support lower uric acid

Lifestyle changes cannot replace medical care, but they can be powerful support tools. Many doctors across Thailand, Laos, Vietnam, Cambodia, Myanmar, India and other Asian countries give similar advice

Hydrate regularly
- Aim to drink enough water through the day unless your doctor gives a fluid limit.
Moderate high purine foods
- Reduce frequent large portions of organ meats and purine rich seafood.
- Normal portions once in a while may be fine for some people, especially if other risk factors are controlled.
Reduce heavy alcohol use
- Especially frequent beer and spirits.
Cut back sugary drinks
- Replace soft drinks and very sweet beverages with water or unsweetened drinks when possible.
Support a healthier body weight
- For people with overweight, slow and steady weight loss may help lower uric acid and improve blood pressure and sugar.
- Avoid crash diets and extreme fasting.
Stay physically active
- Walking and gentle exercise, as approved by your doctor, can support metabolic health.
Manage other conditions carefully
- Good control of blood pressure, diabetes and kidney health is very important for uric acid balance.

These habits do not guarantee perfect uric acid levels, but they may help support a healthier range and create a better foundation for any medical treatment your doctor recommends.

10 Frequently Asked Questions about what causes high uric acid levels

1. Is high uric acid always caused by eating too much meat and seafood
No. Food contributes, but genetics, kidney function, body weight, other illnesses and medicines are often just as important. Many people with high uric acid also have family history, kidney issues or metabolic problems.

2. Why do I have high uric acid when my friend eats more meat and drinks more alcohol than me
Because each person has different genes and kidney performance. Your body may simply clear uric acid less efficiently. Comparing with others is less useful than understanding your own risk pattern and working with it.

3. Can being overweight cause high uric acid
Being overweight does not guarantee high uric acid, but it increases risk. Extra body fat and metabolic changes can increase uric acid production and reduce clearance. Gradual weight loss often helps support lower uric acid levels.

4. Does dehydration really raise uric acid
Yes, it can. When you are dehydrated, the blood has less water, so uric acid becomes more concentrated. Good hydration may help the kidneys handle uric acid more smoothly.

5. Can certain medicines be the main reason my uric acid is high
Yes, in some people. Diuretics, some blood pressure drugs, low dose aspirin and other medications can reduce uric acid excretion or increase production. Your doctor can review your medicines and decide what is relevant in your case.

6. If my kidneys are weak, will I definitely have high uric acid
Not always, but the risk is higher. Weak kidneys are less efficient at removing uric acid, so levels are more likely to rise, especially if there are other risk factors such as high blood pressure, diabetes or heavy diet and alcohol loads.

7. Can rapid weight loss or strict fasting cause high uric acid
Yes. Rapid weight loss and strict fasting increase tissue breakdown, which can temporarily raise uric acid. For people prone to gout, this can trigger attacks. Slow, balanced weight loss is usually safer and more sustainable.

8. Does high uric acid always mean I will get gout
No. Many people with high uric acid never develop gout. Gout risk depends on factors like genetics, how high the level is, how long it stays high, kidney function and other health conditions. But higher levels do increase the chance of gout in susceptible people.

9. If my uric acid is only a little above normal, is it still a problem
A mild elevation is not an emergency, but it can be a warning sign that your metabolism, kidneys or lifestyle need attention. It is a good moment to talk with your doctor about diet, weight, blood pressure, blood sugar and any necessary tests or follow up.

10. What is the safest next step if I have high uric acid on a blood test
The safest step is to discuss the result with a healthcare professional. Ask

How high is my level compared to the target for someone like me
Do I have gout, kidney issues or only hyperuricemia
Are any of my medicines raising uric acid
Which lifestyle changes may help support lower levels in my situation

Together you can create a plan that supports healthier uric acid levels, protects your joints and kidneys and fits your real life, not just the lab number on a report.
