How to tell if your staple line is disrupted?

 I lost 40 lbs. within a lil over 3 weeks after surgery and then all of a sudden for lil over 2 weeks now I have been flexuating between 4 lbs. up and down. Is this normal, I realize you will have stalls but how long is to long not to be losing. My protien has quite a bit of fat tho I was told I dont absorb anything other then carbs pretty much now after my RNY. So now the fat intake from protien shouldnt matter?  Just looking for some insight. Thanx for listening

Symptoms of my staple line disruption were very sulpher like burps and gas. I had cramps that would make me double over in pain. I had chronic backaches and stabbing pains. It would feel like someone was grabbing my boobs, ribs and backbone and squeezing them into a vice all at once.  I went through this for almost a year of self diagnosing before finding out how bad it really was. We know our own bodies best, if something doesn't feel right, get checked. :)
