尿酸 Uric Acid
Uric Acid: Key Indicator of Metabolic and Renal Health
*Uric acid is the final product of purine metabolism, primarily produced in the liver and excreted by the kidneys. It is an essential marker for evaluating metabolic health and kidney function. Abnormal uric acid levels are often associated with gout, metabolic disorders, or kidney diseases.
*Normal Ranges
Men: 3.5–7.2 mg/dL
Women: 2.6–6.0 mg/dL
Note: Uric acid levels can be influenced by age, diet, and lifestyle.
*Elevated Uric Acid (Hyperuricemia)
Common Causes:
-Dietary Factors:
High-purine foods such as red meat, seafood, organ meats, and alcohol.
-Metabolic Disorders:
Conditions like gout, metabolic syndrome, and insulin resistance.
Decreased Kidney Function:
Impaired renal excretion of uric acid.
-Other Diseases:
Hypothyroidism, tumor lysis syndrome.
-Symptoms:
Acute gouty arthritis, often affecting the big toe joint. Uric acid stones causing back pain or difficulty urinating.
*Low Uric Acid (Hypouricemia)
Common Causes:
-Liver Disorders:
Reduced uric acid production, as seen in liver failure.
-Renal Tubular Dysfunction:
Excessive excretion of uric acid, such as in Fanconi syndrome.
-Diet or Medications:
Low-purine diets or medications like allopurinol.
-Symptoms: Often asymptomatic but may indicate underlying health issues.
*How to Maintain Healthy Uric Acid Levels
-Dietary Adjustments:
Reduce intake of high-purine foods like red meat, seafood, and organ meats.
Include more vegetables and low-fat dairy products.
Limit alcohol, especially beer.
-Stay Hydrated:
Drink 2–3 liters of water daily to aid uric acid excretion and prevent stone formation.
-Maintain a Healthy Weight:
Address obesity and reduce insulin resistance, which impacts uric acid levels.
-Exercise Moderately:
Regular exercise helps maintain balance but avoid extreme activities that can trigger uric acid fluctuations.
-Avoid Uric Acid-Triggering Medications:
Certain drugs like diuretics and low-dose aspirin may raise uric acid levels. Adjustments should be made under medical supervision.
-Regular Monitoring:
Individuals with a family history of gout or chronic kidney disease should routinely check uric acid levels.
*Conclusion
Uric acid is a critical indicator of purine metabolism and kidney function. Abnormal levels may lead to gout, kidney stones, or other health issues. Maintaining a healthy diet, adopting good lifestyle habits, and undergoing regular medical check-ups can effectively keep uric acid within the normal range. If abnormalities are detected or symptoms arise, timely medical evaluation and treatment are essential.
