Who should take Ox Bile?

I just bought a few new supplements I’m wanting to try as I get down to why my gastritis isn’t healing. One of the first symptoms I had when my gastritis got really bad was that I couldn’t tolerate fats. Here I am a year later and still can’t. It causes major heart palpitations and pain and then anxiety because of how uncomfortable and scary the symptoms are. I’ve had chronic constipation my whole life but it did get a little better with my extremely restrictive diet and magnesium. Although this is no way to live. I miss food. I have no fat on my body and was already thin to begin with. Fat causes a burn in my stomach like no other. It’s like it just sits in my stomach all night and the next day I’m paying for it. Even small amounts. I bought ox bile because maybe I have a bile thing going on? Scared to try it but I also feel so out of options lately. Willing to try anything. Finally have a GI appointment but not for a couple weeks. Ultrasound and CT scan of my abdomen including gallbladder were all normal. Just can’t get rid of this burn and the inability to eat anything. Carbs and sugar inflame and bloat me like crazy so I don’t eat any of those. Even those from fruits and veggies. Haven’t touched “normal” food in over 6 months. I’m tired of living this way. I also bought new probiotics and activated charcoal. Any advice or stories using ox bile? My GI Map results are also posted on my profile.
