I Had Gastric Bypass 22 Yrs Ago, Never Had a Follow Up, Gaining Weight, What Are My Options?

Had gastric bypass 22 yrs ago, no follow up. I did lose the weight and kept it off up until 3yrs ago, now I cannot lose n keep gaining I have gone from a size 3-4 to a 10! I am told that all the medication i am on does not help, but there must be something, I cannot find/or remember the name of my doctor in denver. I throw up all the time from certain foods I eat, an still I gain weight, there must be something I can do, I paid over $10k for the surgery plus a horrible scar on my stomach
