I had my surgery in April of 2023. Developed Dumping Syndrome/Hypoglycemia probably 3 months later. At first just on occasion after certain meals, getting warm then profoundly sweating and soaking through my clothes. Lightheaded. Then about four months ago episodes so severe I would become disoriented and even hallucinate. At the advice of my thoracic surgeon I started keeping a food diary but there didn't seem to be a pattern. My GP prescribed an in arm glucose monitor, Libre 3, which sends blood sugar levels to my phone and Apple Watch once every minute and that has an enormous help in getting in front of highs and drops. I still need a nutrionist to help me address the actual triggers but at least I am able to mitigate the symptoms. The sensor is by prescription and has to be changed every 14 days but it is simple to apply and absolutely painless. I'm also experiencing weight loss, was 235 prior to surgery and weighed 160 this morning down from about 180 when I came home from the hospital last May, so a slow loss but steady despite trying to eat frequent small meals.
