I am so sorry to hear of your absorption problems! Your concern is very understandable. Unfortunately, I'm not an expert on the doctors in Arizona, however, I'm sure that there is somebody on Connect who might be able to make a recommendation. You can always call the Arizona clinic and explain your problem, I'm sure that they will be able to direct you to the right doctors.
I have also had three surgeries of the upper digestive tract for a rare malignancy called Neuroendocrine Tumors and I'm often concerned about absorption issues as my surgeries were all in the duodenal bulb. If you care to share more, could you explain where in your stomach you had the surgeries and the reason.
I look forward to hearing from you again and I hope you keep in touch and let me know how you are doing with your consult and the absorption issues.
