Several years ago, I was having severe bouts of vomiting and many doctors could not figure out why. Finally, I wa referred to a dr. that completed an endoscopy and went far enought with the scope to discover that I had a twist in my duodenum. The twist would not allow my food to pass through, so I vomited continously. I had surgery and everything was rerouted so that my food could pass through. The twist is still in my body, but my food does not pass through that area. My health question...I have continous bouts of constipation and diarrhea. There will be days that I will not eat at all. I have heard of a vitamin mix that can be added to water called Zoe Life and wondered if that would help me get the vitamins that I am missing from the constipation and diarrhea. I learned quickly that I could not eat steak, salad, most green vegetables, spaghetti sauce, etc. But I do want to make sure I get my vitamins to stay healthy. Any suggestions about this Zoe Life?
