30 kilos gained in 3 months help!!

Hey i really need help if you can mention a dr it will be great here is my story

I had gastric bypass surgery since 2012 everything was okay till last September 2016 anyway my weight suddenly increased in 3 months up to 30 kilos i was 65-70 and in jan 2017 i became 90-95!! I went to the dr complained he said i messed it up so i said maybe i kept a journal of my eatings, plus i hit the gym and i didnt lose weight but in fact i gained weight per day!!! Like a kilo my feet and hands most of times are itchy and swollen and i get severe water retention i use tablets daily ti jus keep the water out, im so tired and frustrated my surgeon didnt ask for any medical analysis i thought it was some issue due to ovary cyst as it happened before i went to gynecologist and he. Found one he gave me something called aldactone 100 and eltroxin 50 daily suddenly it all stopped all the fatigue and the weight gain and i started to come down to 88 after 95 and after like week and half to two weeks it all came back the weight gain etc i got some blood testing
