I had lap band surgically removed wed 5/15/13. today when i stand up my heart rate goes from 70 to 110+ ears ringing & get unclear head feeling?

Dehydrated: Large rise in heart rate upon standing is your heart attempting to compensate for the low blood pressure caused by the change in position. This is also known as "orthostatic hypotension." that unclear feeling is what you get before you pass out, known as pre-syncope. Your should probably call the surgeon that did your recent operation and ask if he wants you to go to E.R. Or just to hydrate up.
