Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry too much. Your conclusion about Irritable Bowel Syndrome could be wrong. IBS has a combination of symptoms. Just slimy stool cannot be termed as IBS. Slimy stool is a blessing. So many people are suffering from constipation. You are lucky in that matter. You are doing good by chnging your diet. The rotten meat smell should be associated with what you are eating now. Stool do have rotten smell because it is in fact rotten. If it is more it could be due to some specific food which disintegrate faster and are kept inside your body for long time before evacuation. Stop worrying about your stool unless the symptom is accompanied by disentry, stomch craamp, excessive tirednss etc. You might need psychological counseling. I am happy to provide telephone counseling. Contact me through customer care service at www.healthcaremagic.com. Hope this clears your doubts. Available for further clarifications. Good luck.
