my father has been suffering from gout since 20 years ago. he uses allopurinol in acute phase. recently he had an operation on his thyroid gland (right thyroidectomy ). two month after surgery he had rising creatinine and urea serum in his blood analysis. ( creatinine 1.7)(urea 21). does this situation dangerous? what we can do for decreasing creatinine amount? where can i find a right diet for him?
