Sudden gout flare-ups may be caused by factors such as dietary taboos, unstandardized medication, lack of attention to joint warmth or strenuous exercise. 1. Diet is not avoided: high purine diet is an important triggering factor for gout attacks, animal offal, broth and seafood and other purine-rich foods into the body can lead to an increase in the production of uric acid, resulting in sudden gout flare-ups. 2. Unstandardized medication: patients with gout in remission should actively take uric acid-lowering drugs to control uric acid levels in the body, if the patient does not strictly comply with the doctor’s instructions to take the drug on time and in accordance with the amount, may lead to fluctuations in the body’s uric acid levels and thus induced gout. 3. Failure to pay attention to joint warmth: gout is mainly caused by the deposition of urate in the joints, if the gout patients do not pay attention to joint warmth, resulting in joints suddenly cold, which may lead to an increase in the deposition of uric acid and lead to a sudden relapse of gout. 4. Strenuous exercise: gout patients to carry out strenuous exercise may lead to increased lactic acid production in the body to inhibit the normal excretion of uric acid, which may lead to the sudden recurrence of gout. Patients with sudden gout flare-ups are advised to go to orthopedics, rheumatology and immunology departments of regular hospitals for detailed consultation.
