Blockage?!
I don't know what sort of "blockage" your friend is talking about. If she means a blockage of the bowel/bowel obstruction---well, I'm willing to bet you've never felt the sort of pain THAT causes! Any time the digestive tract gets blocked, things get painful QUICK.
I'm guessing your 'gain' isn't really fat, but retained water. Have you been eating more sodium than usual? Been drinking less water? (The more water you drink, the less you retain.) And---it's just NORMAL for your weight to fluctuate. Stay off the scales.
Your friend is RNY and has had her intestines rearranged. A blockage would be much more common. Odds are your not blocked, have you been going the bathroom. Like MsBatt, says it is very, very painful.
When I go up, like I did the last 2 days I go back to my journal. Sure enough the carbs have crept up and the protein was lacking.Check out your carbs, protein and water consumption.
. Thanks again the picture is much more clearer. (Hugs)
