hi i am a 23yr male suffering with ibs-d mainly for now on 8yrs. since my symptoms i have been unable to gain much body mass and so am very boney and skinny. i'm slightly underweight but i have paractically no body fat to speak of. because i have mainly ibs d even eating high protein high carb foods does nothing for me. dont feel like i'm digesting properly at all. and with 3 BMS a day straight after meals, its just going in one way and out the other.would like to be able to just gain 15ibs even but just cant do it.has anyone with the same problem found a better solution to putting back on some weight from other supplements or dietary plans? does weight training work also?
