How did they diagnose a polyp? I just read an earlier post somewhere in here of many cases of polyps, actually turn out to be gallstones, which upon doctors removing, have discovered it wasn't a polyp after all.
With regard to weight loss, I also struggle to gain weight, and upon a liver function test its revealed I have gilberts syndrome, which affects the livers ability to absorb fats, therefore making it difficult to gain weight from fats. Carbs just tire me out and leave me feeling depressed and low energy, so that leaves protein. Protein in excess can put extra pressure on the kidneys, so im doomed to be thin unless I eat ridiculous timed diet every day of balanced foods.
