Uric acid problem. Could be the reason?

Hi.. I am 37 yrs and do have uric acid around 6.5-7-8 range (ups and downs) . generally I take zylotic of 100x2 gm a day. Test report as follows- On 12th July - 7 On 23rd July - 6.01 (was taking zylotic 100x2) And same does continuing... On 18th Aug - 9.5 Creatinine - 1.01 Recently I have lost 12 kgs in last 50 days for diet and exercise . But during last and second last report I am in keto diet and 90% + vegetarian food . I am clueless why it may happened. I took spinach , mushrooms, paneer, cauliflower etc thrice a week among other vegetables and flax, chia, water melon seeds. Some places I see spinach/mushrooms can raise uric acid , some other says no. I am confused what could be the reason ? Because if I can't identify the reason I feel it's difficult to control . Pls guide to control and remedy. Thanx
