Uric acid is a waste product formed when the body breaks down purines, substances found in certain foods and drinks. It is usually dissolved in the blood and filtered out by the kidneys, which then excrete it through urine. Maintaining a balanced level of uric acid is important for overall health, as high levels can lead to conditions like gout. When uric acid levels become too high, it can crystallize and accumulate in the joints, causing pain and inflammation. This condition, known as gout, often affects the big toe and can be triggered by factors such as diet, dehydration, and certain medications.
