Many people associate high uric acid with consuming red meat, seafood, or excessive alcohol. However, uric acid is a waste product formed when the body breaks down purines—compounds found in food and naturally present in cells. Kidneys typically filter uric acid from the blood, eliminating it through urine. Uric acid levels rise when the balance between its production and elimination is disrupted.
In some cases, uric acid increases without dietary changes, as purine-rich food consumption is merely one influencing factor. Understanding these underlying causes helps patients better manage their condition.
The body produces uric acid naturally
The body doesn't solely obtain purines from food. Each day, as old cells break down, purines are released and converted into uric acid. If the body produces more uric acid than usual, its blood concentration can still increase, even if the diet remains unchanged.
Rapid cell regeneration, infections, inflammation, or intense physical stress can boost endogenous uric acid production. Consequently, this indicator may rise after illness, injury, or overexertion.
Dehydration impacts kidney function
Dehydration is a common yet often overlooked cause. Even mild dehydration can temporarily alter the body's chemical balance. When the body lacks sufficient water, kidneys struggle to effectively filter waste products. Uric acid then remains in the blood instead of being excreted through urine. Therefore, many people may experience increased uric acid on hot days, after long journeys, or when they don't drink enough water.
Certain medications
Some commonly used medications can affect the kidneys' ability to excrete uric acid. Examples include: diuretics for hypertension treatment, cardiovascular drugs, and long-term medications for chronic diseases. These drugs can reduce uric acid excretion, leading to its accumulation in the blood over time. Patients should consult their doctor if they suspect their current medication is increasing this waste product's concentration.
Kidney health plays a crucial role
The kidneys serve as the body's filtering system, removing approximately two-thirds of the uric acid produced daily. Even a slight decline in kidney function can lead to this waste product accumulating in the blood. Beyond impaired kidney function, metabolic syndrome or genetic factors can also cause a sudden uric acid increase, even with a relatively healthy diet.
Metabolic stress can cause temporary increases
Sudden lifestyle changes can also impact uric acid levels. The body may enter a state of metabolic stress due to factors such as: overexertion, severe illness or infection, rapid weight loss, fasting or skipping meals, or prolonged psychological stress. In these situations, the body breaks down tissues and energy more quickly, leading to increased purine breakdown and elevated uric acid.
