The most important thing is to check your uric acid levels. You can only manage gout by keeping uric acid levels down.
The reason for this, is that old crystals can cause gout flares when they dissolve. I have explained how allopurinol can cause this gout pain, but this is true for any form of uric acid lowering treatment – including diet.
Your doctor can check kidney function to see if this is an issue.
Dietary assessment is simply a question of analyzing the facts. How tall are you, how much do you weigh, and what is a typical day’s food and drink?
