I've been lurking around here & found so much info, I thought I'd come out of lurking.After reading all your stories, I'm embarassed to even write because you guys have been suffering for so much longer, but I don't know where else to turn.On & off I've had some GI problems with diarrhea, but not all the time and it was usually an incident & not consistent. Last month, I underwent open heart surgery. Ever since then, I haven't been able to "go" normally.Basically, I eat, and nothing happens for like a week. I don't feel like I have to go, it's just nothinghappens. Where the heck does the food go if I'm not going?Then, about once a week, I'll all of a sudden start getting rumblings. The first time, the D was immediate, and lasted for 5 hours ( I had to sleep in the bathroom because there was no sense leaving it). There was some nausea too, but I didn't throw up. That's what led me to thinking perhaps IBS because from what I've read, nausea is related to IBS.Last Sunday(a week after the first bout), about 4AM, I woke up with a slight stomachache, which over 2 hours progressed to really big rumblings, but I couldn't go at all. When I finally went, 2 tortuous hours later, it was D. Also, I became nauseous during the 2 hours nothing happened, and did throw up.So, I have increased my water intake, and bought Citrucel. I've been taking it since Monday, upped my fiber (not drastically because I don't want to shock my body), but here we are on Friday, and absolutely nothing has happened since 6AM Sunday night/Monday am.I would go to a GI, but from the sounds of all your stories, most of them don't take it seriously. I understand my body has been through a trauma, but I did see that IBS can be triggered by trauma or stress, both of which has been present the past 6 weeks undergoing open heart surgery.I am not on any medications; I was on Endocet, which can cause constipation, but was also taking Colace (stool softener) to counter the Endocet. I am off both of them and - still nothing.I can totally understand all of your posts. I am becoming anxious as the days go on & nothing happens, which I know will not help matters.So, to recap. To try and right myself, I am:-drinking more water-taking 4 Citrucel tablets with lots of water every day.-taking 1 acidophilus pill.-added more fiber to my diet (nuts & beans for now). -Question - is Metamucil better than Citrucel?Is taking the powder more effective than the tablets? Is this a correct path I am on? And how bad is it to only go to the bathroom only once a week?(I should note, even on my most regular schedule, I'd only go like 2, maybe 3, times a week).Any help you might provide is so appreciated.Thank you so much for listening, I feel less anxious already just having people who understand.
