I am 3 days post op gastric sleeve. My drain has been draining less and less but this morning there is lots. I emptied it and it refilled again(about 30mls). It's not bright red. More red tinged water looking. I feel fine. Did this happen to anyone else??

Check with your doctor but I know I had some days with more Fluid than others. As long as it doesn't smell bad you're probably fine. If you are worried about a leak, drink something with blue or green food coloring. If you have a leak, you will see the color in the drain.
