Im 8 days post op and last few days been feeling very lightheaded and dizzy when i walk ..when sat or laying down im fine. I even get mild pain back of neck and tightness of chest ..all this only when walking

was wondering if anyone else had this???

The dizziness is likely orthostatic hypotension or in simple terms drops in blood pressure with postural changes - getting up after sitting or lying down. You can get it reaching up too. It’s pretty common in the first weeks after surgery & I think aggravated by the low calorie intake but for most it’s temporary. (I had a tendency to it before surgery & now I have it everyday.)

Keep your fluids up. Add a little more salt to your diet if possible. Get up slowly, in stages & wait before moving. When I do move I generally try to keep near a chair, table,wall, etc. so I can grab it & ground myself if my vision narrows. Even been known to grab a person too - LOL.

Depending upon how much weight you’ve lost so far, your upper body pain could be from your body finding it’s new centre of gravity. Your body used to hold itself in a certain way to compensate for the weight you carried. Now it doesn’t have to & your muscles at relearning how to hold yourself when standing, walking, etc. And yes it’s pretty common & can be experienced at different time while you’re losing.
