They gave me Gatorade in the hospital but when I drank a bottle about a month post op, it made me very sick for some reason. Don't know whether it was bad or what but almost immediately after I drank it my output starting pouring out of me, then I started vomiting. Hubby called the paramedics and I was hospitalized for three days for dehydration. Needless to say, I never drank another drop of Gatorade. I was never one to drink much water and still have to force myself to do so, especially nowadays with the hot humid weather and I love the sun.
I was fine with the hydration until the past two weeks when I was hospitalized twice for dehydration. The second time was due to an intestinal virus...man, that was NASTY!!!
As to my immune system, I was sick with bugs more often when I had my colon than after it was removed. I don't get a flu shot either, but, maybe I should. I am sort of scared to get one because I always suffered a reaction afterwards.
