I have always associated Diahorrea with IBS and have only just discovered that IBS can also cause constipation. I have had chronic constipation since childhood. I am 52 now. I have always been trying to get my diet right for my bowels. Despite eating loads of fruit, veg and fibre and drinking about 4 pints of water a day, I will only 'go' once or twice a week. I can only liken it to giving birth. Severe cramping pains in lower abdomen, like someone twisting my insides. Difficulty in passing the stool, sometimes I have to drink strong coffee and walk around a lot. Very exhausted afterwards, sometimes I have to lie down. I also get, milder, stitch like pains in my right side and anal spasms. I have a very sore rear end. It never occured to me to visit my doctor as I assumed that I am aleady having a healthy diet that nothing more could be done. I did visit him about the anal spasms, but he told me to drink more water and eat more fibre. In reality that would mean my meals would consist of nothing but fibre as I was already eating loads. So not much help there. The only time my bowels work normally is when I having a migraine, which I also suffer from, then they can be quite loose and I feel sick. Otherwise I have discovered Linseeds and Psyllum husks which work(with loads of fluid), but I need more than the recommended dose which is worrying. Raw fruit and veggies don't work, so now I mash or puree my fruit and have cooked veggies. I gave up All Bran as that stopped working for me and now I have porridge & mashed banana for breakfast. I don't have much appetite as all this fills me up so much. But at least I can now 'go' about two or three times a week. Does this sound like IBS as I have never been diagnosed?
