Hey, I have symptoms of IBS-D for over 1 and a half year, irregularly however. My stools generally have undigested food particles such as skins of onions and tomatoes or if not, they will be loose. There s some kind of smell that comes from them. The same odor would come if I have acidity I think. As far as I have read about IBS, all this is understandable as I have had very irregularities in eating. However, what really concerns me are 2-3 things. 1st say about a month back, I had a couple of experiences with tarry stools again with the urgency of going to the washroom, like it always happen. Now I ignored this then because I thought it was normal. The stools have not been tarry after that. Secondly, I think I have lost about 3-4 kgs of weight offlate in about a couple of months. Thirdly the acitidity smell with the stool. Any help would be much appreciated. Akash
