For some years now I have suffered from a discharge of clear liquid from the back passage. It tends to be spasmodic but is greatly increased if I make a long plane journey where one is in a cramped position most of the time. I also experience considerable bloating of the abdomen and a feeling like trapped wind. My stools are usually soft which again would indicate the presence of liquid. Apart from raised blood pressure, which is well controlled by medication, I am in robust health. I have had this discharge for more than ten years but it does seem to be becoming worse lately. It is also embarrassing to have one s underwear continually soiled in this way. I tend to think this discharge has yeast as one of it s components. I have tried to relate this problem to my diet so that I could cut out anything that was likely to aggravate it, but I am totally unable to connect it to any specific food or drink. I would be grateful for any observations you can give.
