Hyperuricemia is divided into primary hyperuricemia and secondary hyperuricemia. Primary hyperuricemia is mainly due to a disorder in the metabolism of purines in the body, leading to excessive production of uric acid, which in turn causes hyperuricemia. Prolonged duration can greatly increase the risk of gout. Secondary hyperuricemia refers to hyperuricemia caused by excessive production or excretion obstacles due to some common diseases, the most common being chronic renal failure or some tumors, etc.

What should be avoided with hyperuricemia?

Foods to avoid for hyperuricemia include those high in purines. Here is a list of foods that are high in purines: 1. Seafood, such as some shellfish, shrimp, crab, and certain fishes. 2. Broths that have been simmered for a long time, as they tend to contain higher levels of purines. 3. Certain mushrooms should be consumed less, such as shiitake and straw mushrooms. 4. Animal organs should be avoided as much as possible. 5. Alcohol, especially strong spirits and beer, should be avoided; instead, it's important to drink plenty of water, ensuring to consume 1500 to 2000 milliliters daily.

Treatment of Hyperuricemia

Hyperuricemia is becoming increasingly common in today's life, and its treatment is divided into two main aspects: lifestyle interventions and medication treatment. For lifestyle, the main focus should be on healthy eating, quitting smoking, maintaining regular exercise, and proper weight control. Regarding diet, a strict low-purine diet is essential, especially avoiding the consumption of animal offals, meat broths, seafood, and beer. Additionally, it is important to alkalinize urine, which can be done using substances like baking soda or soda water. Also, ensure to drink plenty of water, maintaining a daily intake of over 2000 milliliters, and control other risk factors that can cause hyperuricemia, such as high cholesterol, high blood pressure, and high blood sugar. In terms of medication, the choice of drugs should be based on the different causes of hyperuricemia. If it is due to a uric acid excretion disorder, drugs like probenecid may be used. If it is due to an overproduction of uric acid, medications like allopurinol could be considered. (Please use medication under the guidance of a doctor.)

Can hyperuricemia be cured?

Hyperuricemia is a metabolic disease caused by disorders in purine metabolism and is clinically divided into primary and secondary categories. Primary hyperuricemia is caused by congenital abnormalities in purine metabolism and is often associated with obesity, dyslipidemia, hypertension, atherosclerosis, and coronary heart disease. Secondary hyperuricemia, on the other hand, is caused by certain systemic diseases or medications. Therefore, whether hyperuricemia can be cured depends on the underlying condition, and the efficacy of treatment cannot be generalized. For hyperuricemia caused by medications or systemic diseases, it can be cured by treating the disease or discontinuing the medication. However, for hyperuricemia caused by congenital abnormalities in purine metabolism, it can be clinically managed by controlling diet and medication, but it is not curable.

Hyperuricemia standards

The diagnostic criteria for hyperuricemia specify that under normal purine diet conditions, if the fasting serum uric acid level on non-consecutive days exceeds 420 micromoles/liter for males and 360 micromoles/liter for females, hyperuricemia can be diagnosed. Hyperuricemia is typically classified into primary hyperuricemia and secondary hyperuricemia, with most patients showing no clear clinical symptoms.

Can people with hyperuricemia drink alcohol?

Patients with hyperuricemia are advised to avoid drinking alcohol. Especially liquors such as baijiu and beer, which have high purine content, are contraindicated for patients with hyperuricemia. Furthermore, if hyperuricemia is diagnosed with high levels of uric acid, one should abstain from alcohol, and also pay attention to diet by avoiding foods high in purines to prevent complications such as gouty arthritis and gouty kidney.
