Lemon water can help reduce blood uric acid because drinking lemon water will produce alkaline substances after a series of metabolism in the body, which can alkalize the urine and promote the dissolution of uric acid in the urine, thus helping uric acid to be excreted from the body. In terms of this effect, it can help lower blood uric acid, but it is not advisable to treat hyperuricemia simply by lemon infused water. Patients need to make lifestyle adjustments, such as adhering to a low purine diet, drinking more water, active weight control and regular physical exercise, all of which can help lower blood uric acid. If the patient’s blood uric acid still cannot be reduced to normal through lifestyle adjustment and is also combined with other metabolic syndromes such as hypertension and hyperlipidemia, it is recommended that the patient should be treated with uric acid-lowering drugs to reduce the blood uric acid level and prevent serious complications.
