[QUOTE="FeltCactus, post: 2350747, member: 535728"] I'm a woman of 46, normal weight. Since my teens, basically since working I get what seem to be sudden bouts of reactive hypoglycemia. Symptoms include everything you can expect, plus at times very low blood pressure, nausea and abdominal pain. Triggers seem to be being late for one of my endless meals, being active before breakfast and eating less carbs, more protein. A typical example for the first is sitting in a meeting that overruns and I'm missing my second breakfast. When I get up to walk back to my desk I get hit. Unfortunately, symptoms last into the evening and often return the next morning to subside again in the evening. A proper crash can last for up to 5 days. So yesterday I experimented and had a breakfast composed only of protein and some fat instead of my usual high carbs with some protein. Just over an hour later the crash came on. Blood sugar dropped by 10mg/dl instead of going up by about 30 but recovered quickly again. I would not have been able to work until 7 in the evening if this was a working day. Btw, traveling in countries where I had only little carbs I felt miserable for the whole 2 weeks and never improved during that time. So now I know this can be brought on by eating too much protein and/or fat indeed. Any other health issues? There's something I'm born with and will hopefully have investigated from next week. I can't fast for more than 2 hours as I just run out of energy when I'm active (that's not a crash as above). Thus if I stroll through a museum or work I just bonk after a max of two hours. I can run a max of 10km, but only very slow and my legs hurt the whole time. I can't walk up mountains without having a microbreak every 50-300 steps for the same. It feels like my body just doesn't know what to do with the oxygen, or how to oxidise fat for energy and I'm running purely on glycogen. Which of course is limited. If I exercise above the anaerobic threshold I might end up in hospital with a mild acid/base problem. Btw, I can only keep this up for a max of 12 minutes. Thus while I run for 6 years now I still can't do tempo runs. I feel that lactic acid might play a role, but I don't know whether it's too high or low. I never had a blood gas test, btw. Thus I have no idea what's going on. Thus, anyone in the same boat or with any ideas? [/QUOTE]
