oh my. i am in a very similar state with a 6” loss. i am 59 years old. i have 10 compression fractures. and intermittent extreme costochondritis. i have a bloated, painful gut and am inexplicably underweight at 98 lbs for the last six months. i have had many GI tests and cancer screens showing nothing amiss or fixable. i agree that my gut is probably contorted due to spine compression. i eat similarly, with grain and nuts on hold now because i have severe daily migraines. (9 ER visits in less than two years). i eat four or five small meals/snacks daily. i wonder if i have adhesions, too. i went to the ER once because my stomach pain was so bad. i was using ice packs on my stomach many times a day for almost a month. it helps and i recommend this. i wish i knew why, while i eat well, with lots of ghee and butter and olive oil, and digestive enzymes, that i remain skeletal. my primary care dr literally told me to stop looking for the reason i feel so sick and weak and am so ‘malnourished’. my GI dr said he has done all the investigation possible for my weight loss and pain. that is really appalling. i will write more, but wanted to jump in with my similar status. my heart to you.
