so this may be a bit TMI but i have always suffered from hyperhidrosis which is basically over active sweating disorder. my main area being my feet. since surgery however,my feet are white, dry and peeling all over the bottoms. its very embarrassing. literally they feel like sandpaper. could this be a side effect of not getting enough fluids in? its not athlete's foot trust me.

I don't know the answer to your question. One of the problems that I had before RNY surgery was an overactive sweating disorder. That disappeared after surgery. But I never noticed my feet sweating before surgery. It was my body that sweated.

After surgery, my face became very wrinkled. These were very fine wrinkles that made me look like I was 100 years old. At my wife's suggestion, I began to apply BioOil on my face once per day and the problem disappeared. BioOil is available at CVS.

The problem might also be related to not getting enough fluids in.
