I haven't ever been one to get headaches or migraines, I hadn't had a headache in over 5 years up until recently. I find myself constantly getting migraines and it actually worries me quite a bit. Along with that, I find that every time I eat I get unbearably dizzy. This happens mid-meal, no matter what I eat, and sometimes it occurs when I'm drinking something like water, milk, juice, coffee. (Those are the only types of beverages I will drink) I'd really just like to know what it possibly COULD be instead of having to go to the doctors and get a huge bill to find nothing. Oh and something else to add, I never got dizzy when eating up until about my 3rd migraine. This has been going on for a month or so.
It can be caused by a GI problem or a neurological problem. Given that you're experiencing migraines, you'll probably want to go see a neurologist to find out what's going on. Something could be affecting your vagus nerve.
