wife gets drained of energy when she eats

Hello there...my wife has a problem after eating a meal where she is extremely fatigued, her heart beat raises significantly, and she is very weak.  It really doesn't matter what or how much she eats...forget going to the mall when she is done.  We have been to numerous physicians, and no one can tel us what is wrong.  Her Father and sister suffer from the same issues.  Her energy level stays in the low-range all of the time.  She is miserable and has been dealing with this for over thirteen years.  Her insulin level always checks out and EKG's are all fine.  Can anyone relate an advise?

this sounds exactly like me. does she have to lie down after eating because she is suddenly exhausted? heart begins to pound? dry, salty taste in mouth? I will sleep for a couple of hours and awake not rested at all but heavy, lethargic, confused and unable to move or concentrate for awhile. I slowly come out of it and feel very thirsty. I have no idea what it is but am seeing a doctor this week to try to figure it out. From my research online it seems like dehydration can be a factor....from simply not drinking water or as a side effect of diabetes insipidus or a adrenal gland or thyroid gland problem. If I find out anything more, I'll let you know.

I don't know anything about your situation, but I have found that naturopathic physicians are much more knowledgeable and helpful in health related problems that know regular doctor is able to diagnose.
