For patients with hyperuricemia, we generally need to limit the intake of high-purine foods, such as crab and animal offal. Moderate consumption of medium-purine foods, such as meats and fish, is acceptable. Low-purine foods like vegetables, fruits, milk, and eggs can be safely consumed. For example, fruits like grapes, pears, grapefruits, kiwis, and dragon fruits are all acceptable to eat. However, many patients with hyperuricemia also have other metabolic abnormalities, such as high blood sugar. In such cases, it is important to monitor the quantity of fruit intake because excessive consumption can lead to fluctuations in blood sugar levels. Therefore, fruits can be safely consumed by those with hyperuricemia, but attention must be paid to any additional metabolic abnormalities that may be present.

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.

How is hyperuricemia treated?

The treatment of hyperuricemia mainly includes the following points: 1. Improve lifestyle primarily, including a low-purine diet, appropriate exercise, smoking cessation, and increased water intake. 2. Alkalize urine using sodium bicarbonate to maintain urine pH value between 6.2 and 6.9, which facilitates the excretion of uric acid. 3. Avoid drugs that increase uric acid levels, such as diuretics, corticosteroids, and insulin. 4. Use medications that lower uric acid levels; drugs that increase uric acid excretion mainly include probenecid and sulfinpyrazone, and drugs that inhibit uric acid synthesis mainly include febuxostat and allopurinol. However, the treatment with these drugs has specific indications, contraindications, and related side effects. It is advised to use medication under the guidance of a doctor and avoid choosing drugs for treatment arbitrarily.

Can people with hyperuricemia eat eggs?

In the case of hyperuricemia, we primarily recommend a low-purine diet to prevent the onset of gouty arthritis. As for the nutritional content of eggs, they are considered a food with a moderate level of purines. Therefore, when uric acid levels are relatively high, it is still possible to consume them in moderation. Aside from diet, it is also necessary to drink plenty of water or to alkalize the urine using baking soda tablets even if there is a transient increase in blood uric acid levels. If sufficient water is consumed, it is less likely for deposits to form in the joints. If deposits do not easily form, it also relatively reduces the possibility of triggering inflammatory responses, thus preventing the occurrence of gouty arthritis. Therefore, it is possible to consume an appropriate amount of eggs, but it is also important to drink plenty of water and appropriately alkalize the urine.

Causes of hyperuricemia

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.

Hyperuricemia manifestations

Most cases of hyperuricemia usually have no obvious clinical symptoms, and it can take years to decades from the increase in blood uric acid to symptom onset, with some individuals never exhibiting obvious clinical symptoms throughout their lifetime. However, as age increases, the incidence of gout becomes higher. When accompanied by acute gouty arthritis, patients may experience severe joint pain. If blood uric acid levels remain high over a long period, this can lead to the formation of gouty tophi and uric acid stones, among other issues.
