Hi. I Had Gastric Sleeve Surgery On Dec 10 And

hi. I had gastric sleeve surgery on dec 10 and i started protien drink yesterday. It seems my heart beat is skipping or giving me a hard beat every few minutes especially after eating. i am on meds for aFib which I first had on October 2 for 6 hours. i am on Digoxin, losartan,Cartizam and Metroprolol. I have taken meds every day all except cardizam which i did not take from dec10 till today. I never went afib before oct 2 or after. could gastric sleeve surgery cause the skips and hard beats?
