Therefore, people should focus on making long-term sustainable changes to manage their weight, such as becoming more active, eating a balanced diet, and choosing nutrient-dense foods. The heavy consumption both of alcohol and of sugary drinks — such as sodas and sweetened juices — correlates with an increased risk of developing gout. Alcohol and sweetened drinks also add unnecessary calories to the diet, potentially causing weight gain and metabolic issues.

Some research indicates that people who drink coffee are less likely to develop gout. A handful of studies have also linked coffee consumption to a lower risk of cardiovascular disease. A systematic review and meta-analysis of long-term coffee consumption found that people who consumed 3—5 cups of coffee per day had the lowest risk of cardiovascular disease.

As people with gout have a higher risk of cardiovascular disease, drinking coffee may help improve their overall health. Taking a vitamin C supplement may lower the risk of gout. A meta-analysis of 13 randomized controlled trials found that vitamin C significantly reduced levels of uric acid in the blood. Reduced uric acid levels could lower the risk of gout attacks. Research has not conclusively proven that vitamin C treats or prevents gout, however — only that it lowers uric acid levels.

Preliminary research suggests that cherries might reduce the risk of gout attacks, particularly in people with a prior history of the disease. This effect persisted even when researchers controlled for risk factors, such as age, sex, alcohol consumption, and use of diuretics or anti-gout medication. Gout is a painful medical condition that often occurs alongside other serious conditions.

While a healthful lifestyle may lower the risk of subsequent flares, it may not be enough to treat the disease. Some people with balanced diets still get gout, and not all people who eat high-purine diets develop gout symptoms. Medication can help reduce pain and may prevent the risk of future gout flares. People can talk to a doctor about their symptoms and ask for advice on which lifestyle changes might be most beneficial.

Gout is a type of arthritis that causes painful symptoms. There is no cure for gout, but people can manage the condition with medication and home….

Abstract Uric acid is synthesized mainly in the liver, intestines and the vascular endothelium as the end product of an exogenous pool of purines, and endogenously from damaged, dying and dead cells, whereby nucleic acids, adenine and guanine, are degraded into uric acid. Introduction Uric acid Fig. Endothelial function In contrast to studies documenting the ability of uric acid to impair vascular endothelial cells integrity [12] , a recent report indicated for the first time that extremely low levels of serum uric acid, attributed to loss-of-function mutations of SLC22A12 encoding blood vessels and kidney proximal tubular cells transporter, URAT1, cause endothelial dysfunction in vivo [13].

Potent mediator of type 2 immune responses Elevated concentration of uric acid was detected in the peritoneal cavity of mice following injection of the most widely used clinical adjuvant alum aluminum hydroxide [16] , [17].

Resistance to parasites The protective immune response against many helminth parasites is dependent on type 2 immune responses [23]. Defense against neurological and autoimmune diseases In support, plasma low uric acid levels, leading to decrease in antioxidant molecules, were evident in patients with multiple sclerosis. Uric acid dread: Pathogenic potential of uric acid Gout Despite its documented protective potential, mentioning uric acid generates apprehension as it is the confirmed aetiological agent of the severe, acute and chronic inflammatory arthritis, gout.

The alarming steps Recently, MSU crystals were identified as an endogenous danger signal formed after release of uric acid from dying cells. Renal disorders The kidneys play a major role in the regulation of serum uric acid levels as approximately one third and two-thirds of the uric acid produced in humans is eliminated by the gastrointestinal tract and kidneys, respectively.

The metabolic syndrome Metabolic syndrome is the name for a group of risk factors that raises the threat for heart disease and other health problems, such as diabetes and stroke. Cardiovascular diseases Hyperuricemia was shown to be implicated in development of hypertension and cardiovascular diseases, via induction of growth factors, hormones, cytokines and autacoids [98] , [99] , []. Insulin resistance and diabetes type 2 An elevated serum uric acid is also one of the best independent predictors of diabetes and commonly precedes the development of both insulin resistance and diabetes type 2, as it was discovered that one quarter of diabetes cases can be attributed to a high serum uric acid level and elevated serum uric acid levels were found to be closely associated with insulin resistance and diabetes mellitus type 2 [] , [].

Non-alcoholic fatty acid disease Numerous clinical and experimental reports have documented association between high serum uric acid levels and non-alcoholic fatty liver disease NAFLD [30] , [31] , [32] , [33] , [34] , [35]. Conclusions and future perspectives The contribution of uric acid to development and progress of gout and metabolic syndrome appears to be well-established. Conflict of interest The authors have declared no conflict of interest.
