Really, there are no great treatments for it. I take Reglan to propel the GI tract and am learning how to eat accordingly. Low-fat Japanese-type food seems to work and soft foods. Nonetheless, I always have varying degrees of pain, discomfort and PN after eating and even when not eating. Moving about seems to help.
I do not have diabetes but yes, I have read that it is often the cause. I don't know what started this mess regarding my case.
I am sorry to know you are ill. I hope the best...
