With my SMAS I'm 15 pounds underweight, almost malnourished for my size. They're going to put in a NJ tube, but now I'm wondering if a j tube makes more sense. They say that's more long term, and easier to live with. But the possible complications my dr listed were unnerving. I have food sensitivities, and it might just come down to which formulas I can tolerate and which tube diameter they're better with. I'm just looking for perspectives or experience, because I'm overwhelmed.
