HI Icr319 - sorry to hear you are having problems. I am responding to your comment, 'is IBS a catch phrase?' It is somewhat of a joke (well, not really a joke but for lack of a better word)around here that the docs give you an IBS diagnosis when they can't find anything else. I had severe nausea for months, lost 25 pounds- got real thin- and was told, with no tests, that I had IBS and I needed to 'relax'. That is one of the real bummers for me- everyone thinks that people with IBS are just stressed out and it's all emotional. I just want to spit when people imply that. I'm a 31 y/o woman who has years of mental health training and counseling (both giving and receiving). I think I know my body and my symptoms, thank you. Anyway, I finally had an extensive workup and still, IBS it is. I have D sometimes, C sometimes, severe abdominal pain at times and the good old nausea which is so uncomfortable at times, i think I might scream. I know I sound very negative but really I feel positive (honestly)- I am taking steps to improve my emotional and physical health and to feel better. As far as your constipation question, canyonbabe's reponse was a good one. It is hard to know when to do what sometimes. You may want to try a fiber supplement daily- that tends to regulate most people- but again you should check with your PCP before commencing anything. Good luck.
