Need to lose 5%?!

Call your surgeon's office and talk with them about what you see happening.  I would also stop weighing everyday--your scale will not be your friend if you are using it daily.  You gain may be water gain?  How much water are you drinking every day?  Again, talk to your surgeon's office about your concerns.

Some are very strict about it, others, not so much. Mine had a similar requirement, but the weight loss was due at my pre-op appointment the week before surgery.  I can't imagine them turning a prepped patient's $$$ away on the day of surgery, but you never know. You should talk with your team about your concerns. Keep in mind that if they make you do clear liquids a day or 2 pre-op or especially if they have you do "bowel prep", you're gonna lose at least 5 pounds in water and poop in a very short period of time!
