Sometimes right after I wake up or in the late afternoon I get intense nausea and vomiting. This subsides pretty quickly if I manage to choke down something starchy. What is going on?
It happened again this morning and I'm kind of frustrated. This happens once every 3-4 months or so. It usually happens in the morning, about 5 minutes after I get out of bed.
This morning was typical- I got up, went into the kitchen and started coffee. I felt fine when the coffee went on, but before it was finished brewing I was incredibly sick. The nausea is really intense, so that for a minute or two I can't stop heaving, and I feel waves of heat and dizzyness that make it impossible to stand up. When I feel un-dizzy enough to stand up, I scarf down a piece of bread and work really hard on not throwing it up. If I manage to keep it down I invariably feel better within 10 minutes, sometimes sooner. My ribs are often sore for the rest of the day because of the intensity of the heaving.
When it happens in the afternoon it is always when I didn't eat enough for lunch or let lunch get away from me somehow- I start feeling hungry, and then the hunger turns suddenly into intense nausea.
What is going on? This has been happening for at least 5 years, although it seems to be getting somewhat more frequent in the last year. I asked a doctor about it a few months ago and she said it sounded like textbook hypoglycemia, but when I did a fasting glucose it came back normal.
Is it possible to have only occasional hypoglycemia? The hunger turning into nausea think makes me think it must be related, but I don't get nauseaous every single time I get hungry.
Could there be something else causing this? Could there be something my stomach is trying to get rid of that gets "sopped up" by the bread?
Possibly relevant other things: I am a vegetarian and eat very little dairy, but some eggs. I have also been having occasional sharp pains in my abdomen- nothing too bad but distracting. They are usually in the upper middle right quadrant (my right), but sometimes on the left side as well. These have only been happening in the last few months or so, and I think they might just be stress-related. Also, this only happens when I haven't been drinking, so it's not just that I'm hungover.
It's probably hypoglycemia, or at least "low blood sugar". I have had similar periods in my life, although it's not quite as bad as you describe at the moment. Diet is the solution; not necessarily what you eat, but when you eat it. Maybe eat a snack, or drink some juice, shortly before bedtime. Keep a granola bar (or other carb-rich munchy) in your backpack or purse as a "crap, no time for lunch now but I don't want to feel crappy later".
Basically, when you start to feel tired or weak, that's a sign that your blood sugar is too low already. If you don't correct it (and ideally, it shouldn't get to that point anyway), you'll eventually notice the symptoms you describe: diziness, nausea. So keep it from getting to the warning signs, and be ready with a backup snack in case it does get there.
