Just found this group after 20 years [correction - 30 years!] living with bile salt malabsorption from radiation to treat leukaemia.
I reckon my weight has been a steady 20% less than it should be. And I have a very low BMI.
Cholestyramine has made a HUGE difference to my condition.
But has anyone found a way to increase weight?
I'd love to gain even half a stone!
