I just got back from md folks, have maintained my after surgery weight of 187, (Yeah) but the lightheadedness/dizzyness he said is probably from the blood pressures medicines. My bp when he took it was 110/60. I take one in am and one in pm, the lost of 30 lbs so suddenly can certainly affect these. So if someone is taking any and experiencing same, contact the dr that rxd them to you and explain to him whats going on, Miss Meow, because I was getting lapband, my eye dr, opted to wait to rx me new eyeglasss perscriptions till after because yes, the weight loss can affect our eyes, the change in the water in our bodies has a great deal to do with our eye sight. I tend to be like you all these new little nusisances I tend to blame the surgery, Oh the things we learn on this new journey! But I feel so much better now, knowing it wasn't me being all anxious, it really was something going on!
