I've been avoiding asking this for awhile because I'm concerned it might be too specific, but I'm hoping someone might have some suggestions and maybe it will help someone else.
I've been paleo for 4 months to help with digestive issues, mainly constant bloating and stomach pain. I've always been active and even though I ate grains, I relied relatively little bread, gluten, or sugar. In 2005, I began getting sharp pains under my right rib cage. I was tested positive for h. pylori and was treated with some serious antibiotics. I've always been slim, but a few months later, I inexplicably lost a few pounds (down to about 95lbs at 5'4") and consciously ate more to gain it back, which sometimes made me feel a bit sick. One day in 2006, I woke up seemingly out of the blue with an extremely bloated stomach that never went away. I get a tightness under my ribcage and my lower abdomen looks very distended--feels worsened by eating I think. I've even been told I look pregnant (in case I thought I was imagining it...).
I tested negative for celiacs (which, I realize means little), I've had ultrasounds, endoscopies, colonoscopies, MRI, etc. Nothing really was notable on the tests (liver/gallbladder normal) except on the MRI it was noted there was possibility of median arcuate ligament in the way of the celiac artery, blocking some blood flow to the stomach. But, I was also told this wasn't in any way a "final" diagnosis as many have this issue with no symptoms.
In May I went back to a new doctor who told me I had low vitamin D and a dexa showed osteopenia, which I posted on here: http://paleohacks.com/questions/38814/osteopenia-thoughts#axzz1XCjb5A8t. The only thing doctors have suggested have been IBS medication or do nothing, but now that I'm showing some bone loss (at 28!?) I feel I should find out how to make this better and that medication is not really going to do much for my bone density (even if I could live with the bloating).
Going paleo and supplementing with vit D has helped me have more energy and mental energy, which I appreciate, though I think there is more to do on that front.
I was low-ish carb (50-70g) paleo/no dairy for about 4 weeks and now I'm more moderate carb (~100-120g) with dairy in the form of kefir and butter, with no difference with stomach aches. I supplement with 400mg Nat Calm, which has eliminated constipation I think. I also take 4000 units vit D/day. I've been on/off probitics and not sure if they make a difference. I run/lift/yoga most days and I'm back to about 103-104 lbs/14% bf.
What's the next step? Should I try a GAPS diet? See yet another (maybe more alternative) doctor? Do I need to get my ligament resected (seems rather un-paleo)? Live with it?
