Hyperuricemia is mostly asymptomatic, meaning there are no uncomfortable symptoms. It is usually discovered during physical examinations or blood tests when the uric acid level is found to be elevated, around 420, which is considered hyperuricemia. What causes it? It is mainly caused by poor lifestyle habits, such as long periods of drinking alcohol, excessive intake of animal organs, seafood, barbecue, and too much protein intake. Additionally, some people may develop high uric acid levels due to prolonged use of diuretics. When hyperuricemia occurs, it is essential to change lifestyle habits, but at this time, no special medication treatment is needed.

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.

What foods should be avoided with hyperuricemia?

Hyperuricemia generally requires a low-purine diet. So, what foods should be avoided? First, seafood and sea fish, as they have a high purine content and should not be consumed. Second, avoid animal organs like chicken and duck kidneys. Third, abstain from alcohol, especially strong spirits and beer, which tend to raise uric acid levels, so it's recommended to avoid them. Fourth, it is advised not to consume long-cooked broths, such as those commonly enjoyed in Guangdong where the broth is simmered for several hours, as these also have high purine content. Fifth, limit intake of some bean products and various mushrooms, as these should also be consumed minimally.

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.

Is hyperuricemia dangerous?

Hyperuricemia is generally diagnosed when the blood uric acid level in males exceeds 420 micromoles per liter and in females exceeds 360 micromoles per liter. Some patients with hyperuricemia are asymptomatic, but others may develop gouty arthritis, characterized by local joint redness, swelling, heat, and pain, and even limited mobility. Some patients may develop gouty nephropathy, leading to abnormal kidney function. There are also instances of patients developing tophi, which can cause joint deformity and even limited mobility. Therefore, if hyperuricemia is not controlled promptly, it poses certain risks and may lead to complications such as tophi, gouty arthritis, and gouty nephropathy.

Hyperuricemia and Its Complications

Hyperuricemia mainly refers to the elevation of uric acid levels in the blood, with levels exceeding 420 umol/l in males and 360 umol/l in females being diagnostic criteria. Some patients with hyperuricemia may not show symptoms, but if not controlled, complications can arise such as gouty arthritis, which manifests as local joint redness, swelling, heat, and pain, and even limited mobility. If it affects the kidneys, it leads to gouty kidney, which is characterized by abnormal kidney function and elevated creatinine levels. Therefore, if diagnosed with hyperuricemia, it is advisable to control diet, drink plenty of water, and seek timely medical treatment.
