I'm about 2 weeks since my rny and over the last couple days I've started being more active and have started getting slightly dizzy after I bend over and raise back up or stand up to fast . And today I was bent over dumping out a bag of potting soil and after I stood back up got dizzy to the point of having to grab onto something . I do a pretty good job of getting my fluids in usually 50 + Oz everyday . Protein not so much it's still hard to stomach the shakes so I'm only getting about 25g a day protein . Could it be lack of protein or a BP issue BP has been all over the place since surgery.
