I had lap band with plication on April 25, so a little over three weeks out. I started feeling light headed on Monday of this week, whenever I stood up... So, I checked my blood pressure and noticed it was lower than I've ever seen it while on my bp meds, so I called my regular doctor, not surgeon, to just see if maybe my bp meds needed to be adjusted and to get a checkup post surgery with someone else...

Turns out doc things I'm just dehydrated. I'd started having shortness of breathe over the weekend, while climbing my stairs and just generally weaker than I've felt. Anyway, she said it's probably dehydrated and ran some blood tests. Blood work turned up nothing except high Calcium levels. I've notified surgeon and waiting for a response, so just wondered if anyone else experienced that or similar. She did say the high calcium should not have made me feel light headed but dehydration is still main diagnosis until she speaks with surgeon...

May ask your Dr. to check your B12 levels. Its a level that gets over looked and takes awhile to show up but might explain some of your symptoms.
