My POTS symptoms began in 1993. Ever since then, I have had issues with feeling bad after I eat. Carbs and sugar are the worst triggers, but so are large meals. My symptoms are: tachycardia, shakiness, weakness, strong urge to lie down, hungry about 2 hours after I eat, difficulty concentrating for a couple of hours after I eat, bloating, and sometimes dizziness. Breakfast is worst for me but I am able to tolerate more foods by evening. I have discovered that eating smaller meals and adding a fat or protein to my meal helps. I always thought that my symptoms were the result of delayed gastric emptying, but recently came across the description of something called dumping syndrome (or rapid gastric emptying). People who have this have usually had stomach surgery of some sort, but some people who have it have not had surgery. I have not. The only surgery I had was to remove ovarian cysts and a gangreene, abcessed appendix. This is; however, when all my POTS symptoms started, including the symptoms described above. Has anyone else heard of a connection between POTS and dumping syndrome?
