Vomiting 8 years after sleeve gastrectomy revision

I had a revision done 8 years ago and today out of nowhere I vomited what smelled like food I ate weeks ago. The revision was done originally in 2016 due to my gastric bypass producing a separate pouch, and since I had two stomachs. The bypass was done in 2000 and it’s definitely help me lose weight however it’s concerning the vomiting smell of food at eight days even a couple of weeks ago.
