I'm a 40 yr old female, slightly overweight, who has occasionally in the past had isolated episodes of what seems to be hypoglycemia (weakness, "cottonheadedness" etc) that were caused by obvious triggers such as a large carb-loaded or sugary meal taken on an empty stomach. These episodes would last 1-2 days, the symptoms recurring with subsequent meals until they would resolve and I'd be fine again. I've tended to avoid large carby meals on an empty stomach and this has worked fine.
I am in the middle of an unprecedentedly persistent "vicious circle" of what seems to be reactive hypoglycemia, but am not sure what the trigger was this time. It has lasted nearly a week with no end in sight. The only thing I can think of as a trigger was a beer which was drunk quickly on a not-completely-empty stomach. (I don't drink alcohol very often, and usually with food.) Since then, 2-3 hours after every meal, not just carb-loaded ones, I become extremely fatigued, in addition to the usual constellation of "cottonheaded" symptoms - some so bad that I feel I must pull over while driving. The extreme fatigue was never part of previous attacks. It has gotten so bad this week that each morning I wake up feeling like I've been run over by a Mack truck. Trying to eat non-carb-loaded foods doesn't do much to bring me round. It's carbs or nothing, which then prompts another crash 2-3 hours later. I'm at a loss as to how I can bring myself down from this cycle of eat-crash-eat-crash... I can't just nibble protein power bars all day.
I am not on any medications, although I probably take caffeine more than I should... I am not depressed, not under unusual stress, and my symptoms are very clearly linked to food intake.
I'd like to see a doctor for an initial visit about this (to see if I have measurable hypoglycemia - I guess that is doubtful for RH a lot of the time, from what I've read). Am discouraged to hear how doctors say "it's all in your head" just because their glucose meters read "normal" - but I would like to at least know where I stand. How should I approach my doctor so that I will be taken seriously?
Also, what foods CAN I eat? I hear so many conflicting pieces of advice. "Rice, yes -- rice, no" -- "fruits, yes -- fruits, no" ...
