Mom has gotten sick and had the same symptoms for 3 to 4 times now. Her symptoms are painful abdomen bloating around her belly button, (she feels like her belly would pop) diarrhea, smelly gas from both ends, (worse than rotten eggs ) and grey vomiting. They have told her everything from a blockage, (which further testing proved to not be the case) appendix or gallbladder (which she has had removed in her 30 s) She is a diabetic and they mentioned her pancreas was shutting down or malfunctioning, and sent her a specialist that said it was not. She has gotten dehydrated, so they put her on a clear liquid diet , and the illness seems to last about 2 weeks and only about a week apart before symptoms return. She also gets a slight headache with black and white zigzags in both eyes that appear bright like lightening bolts (that she never had before till she got this stomach issue) then nausea, then comes the vomiting and other symptoms. They told her it is related to her migraines but during this time she only remains to have a slight headache.
