Does anybody think or have any knowledge of ibs being related to being very skinny. A bit random I know but I'm 32 and have always been extremely skinny, I've had blood tests done in the past ruling out anything major so just put it down to ibs. My symptoms are predominantly bloating, an uncomfortable full up feeling with never any appetite. I do have huge anxieties socially and with OCD which is what I blame for causing these pretty constant daily symptoms, but sometimes I feel that as I'm extremely skinny maybe my stomach is so small that any substantial amount of food it cannot cope with. Subsequently causing bloating and discomfort.
