I am 11 weeks post tummy tuck (muscle repair, mons, and lipo) and I am always hungry! Is this a common side effect?

Thanks for your question.  It is not uncommon to have changes in appetite after surgery.  Your body needs a few extra calories to heal, but don't let that get out of control and undo all the work of the TT.  Listen to your body, drink lots of water and make sure you're not eating for other reasons! Best Wishes!
