I had very large hiatel hernia repair (75% stomach up in chest, with twist & multiple ulcers) with mesh repair and also had nissen wrap 5 days ago. Doing pretty well, still mainly on clear liquids with little milkshake here and there. Dr wants me to take it slow b/c surgery was hard (> 5 hrs) and do mainly clear liq for first week, then progress to full liquids for week, etc. My bowels started waking up on 2 days post op (Gas) has several BM yesterday, but now today I have BAD diarrhea. Its now all liquid, and am afraid I can't drink enough to keep up with it. Have taken Immodium (Crushed) and it has slowed a little. Has anyone else experienced this? I have IBS and from time to time have bouts of this, but with me already weak, the timing is lousy. Any input appreciated. I can usually drink milk with no problems at all.
