Hi I have been having repeated episodes of extreme pain high on the ruight side of my belly. One episode put me in the hospital. At arrival to the ER my liver enzymes were normal (104, and 108), but climbed to 1104 and 1186 overnight. My bilirubin was normal. thru cti, mri, the deeper mri, colonoscopy and upper endoscopy they ruled out stones, blockages, infections. The GI said everything was normal. Nevertheless, the episodes continue. What would be the next most likely cause? To give you some background, I don t drink, use drugs other than my prescribed ones, nor do I smoke. I am overweight with type 2 diabetes and hypertension. We stopped the Metformin as it was contraindicated by the testing, then stayed off it.
