Someone please explain to me why, when I was in the hospital for 6 days, 4 of them were clear liquids only, 18 hours with NPO (nothing by mouth with a complete clean out) and a Saline IV with strong antibiotics, did I gain back 8 of the 25 pounds I had lost? It doesn't make any sense to me. Had no outside food while I was in there and just a GI soft diet on the day I could eat.
