Gout is categorized into primary and secondary. The formation of primary gout is related to heredity, while the formation of secondary gout may be related to hyperuricemia, taking medications and other diseases. 1. Primary gout: related to genetic factors, caused by inborn purine metabolism disorder or uric acid excretion disorder. 2. Secondary gout: clinically, gout occurs in patients with hyperuricemia. When uric acid excretion is impaired or uric acid production is excessive, it may lead to an increase in uric acid in the body, thus inducing gout. The use of drugs such as hydrochlorothiazide can cause a decrease in uric acid excretion, leading to gout. Other diseases such as kidney disease and obesity may also lead to abnormal uric acid metabolism, thus causing gout. It should be noted that gout patients usually do not eat purine-rich foods, such as broth, animal offal and seafood, so as not to aggravate the gout. Once there is discomfort should be timely medical treatment, so as not to delay the condition.
