I had RNY Friday, and I am pretty sore and my belly feels swollen, I have been able to get fluids down, so that is a plus. My question is, the scale hasn't budged at all since I went into the hospital. Does it take a little while for the scale to start moving?

Yes don't weigh yourself for 2 weeks xc

It took a good week for all the extra fluids to wash out. Then I lost 16lbs the next week. Now I am at the dreaded three week stall.

My Dr told me the scale is irrelevant for the first 2 to 3 weeks as the body heals. I know I gained 15 to 20 pounds the two day after surgery. He said the body gets a little out of wack SINCE HE TOTALLY REWIRED YOUR DIGESTIVE TRACK! HE made me laugh at that one.

He told me to note weigh until i see him for follow up.

I had RNY April 20 and no one warned me about the 3 week jam. I lost 27 pounds before the 3 weeks and went for 10 days before I started losing a half pound to one pound a day. Some days it weighs the same. How long does this slow down last? It is so depressing.

the three-week stall usually lasts a week or two, but I've known of a couple of people who had it last for 3.5 weeks. Mine lasted for two weeks and after it broke, I settled into a pattern like you described - a half pound to a pound a day. I lost at that rate for the first six or seven months, then it slowed down even more (actually, after the first month or two, it was more like a half pound a day, if that...). It adds up over time, though. I've lost a total of 236 lbs. Just stick to your program and be patient and the weight will come off..
