Small Weight Gain During Recovery Phase of Abdominoplasty

Recovery from ALL surgery involves an acute phase of healing which involve inflammation associated with fluid retention, tissue stiffness and woody feeling. At 2 weeksafter aTummy Tuck,I would NOT worry about and would STRONGLY advise you against short-sighted diets. This is NOT the time to deny your body the nutrients the healing process requires. I would recommend you eat a diet high in proteins and resume exercising gradually when your surgeon recommends you do.
Be patient. You will be glad you did.

It is not uncommon to gain a few pounds in the first few weeks after surgery, both due to inactivity, and also fluid retention (all kinds of surgery cause you to gain "water weight" for the first week or so after).  This is nothing to worry about.  Take it very easy now, take good care of yourself while you're healing so that you can get back to your normal routine as quickly as possible.  Eat a sensible diet of course, and the weight will fall off once you're released back to full activity.
