What causes high uric acid levels in children?

Generally, high uric acid levels in children may be caused by improper diet, genetic factors, gout, glomerulonephritis, or diabetic nephropathy. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Improper Diet

If a child consumes excessive amounts of high-purine foods over a long period—such as seafood, animal organs, and meat—these foods produce large quantities of uric acid during metabolism, which may exceed the kidneys' excretory capacity, leading to elevated uric acid levels. Therefore, it is recommended to adjust dietary habits appropriately by including more fresh fruits and vegetables such as apples, dragon fruit, kiwi, and spinach, which can effectively help alleviate the condition.

2. Genetic Factors

If immediate family members have a history of hyperuricemia, children may also develop this condition due to genetic predisposition. Under medical guidance, patients may take medications such as benzbromarone tablets, febuxostat tablets, or indomethacin tablets, which can help lower uric acid levels.

3. Gout

Gout is a disease caused by excessively high uric acid levels leading to the formation of uric acid crystals in joints or soft tissues. Although gout typically occurs in adults, it can rarely affect children as well. As directed by a physician, patients may take medications such as ibuprofen sustained-release capsules, etoricoxib tablets, or colchicine tablets to help relieve pain.

4. Glomerulonephritis

Glomerulonephritis is an inflammatory condition affecting the glomeruli, which may impair their ability to filter uric acid, resulting in uric acid accumulation in the body and thus causing elevated levels. Patients may follow medical advice to use medications such as furosemide tablets, compound captopril tablets, or losartan potassium hydrochlorothiazide tablets for treatment.

5. Diabetic Nephropathy

Diabetic nephropathy is one of the common complications in patients with diabetes. Prolonged high blood glucose levels may damage the kidney's filtration function, increasing uric acid retention in the body and leading to high uric acid levels. Under medical supervision, patients may use medications such as dapagliflozin tablets, sitagliptin phosphate tablets, or furosemide injection for treatment.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and cultivate healthy lifestyle habits.
