Some patients with hyperuricemia are asymptomatic, while others may suffer from complications such as gouty arthritis, gouty nephropathy, and tophi. Gouty arthritis is very common clinically and is primarily characterized by localized joint redness, swelling, heat, and pain. The commonly affected joints include the first metatarsophalangeal joint, ankle joint, and wrist joint. In cases of gouty nephropathy, patients may exhibit high levels of uric acid and increased creatinine levels, which may manifest as frequent urination, nocturia, and swelling of the lower limbs. If gout crystals deposit in the joints, they can form tophi, leading to joint deformities and restricted movement.
