Had surgery may 4. Yesterday started having this feeling like my heart was beating in my head, I drank and it went away then it came back. Today same thing is happening. I called the dr they said that's what it has to be, for me to keep drinking and call tomorrow if it still continues.......anyone had this happen? Maybe I'm not eating enough?

I had my surgery on a Tuesday. Went home on Wednesday. On Thursday morning, I ended up back in the hospital dehydrated. After a swallow test and a couple of IV bags I was fine and went home. Forced myself to drink after that.

Probably a combination of dehydration/lack of calories. Focus on drinking more. Sip sip sip.

yeah, i was only drinking half the water i was supposed to and kept having dizzy spells when i would stand up. once i started drinking more water it went away.
