Effect of fasting on AEDs?

[RainbowBrite]

I was wondering if anyone knew what the effect of fasting or decreasing caloric intake/food more than usual can have on anti-epileptic drugs and their blood levels? I've been having trouble with my eating disorder and wondered how it's effecting the medicine.

Well, aside from issues of low blood sugar (a seizure trigger for many), and the overall metabolic imbalances that can result from fasting, there is also the specific possibility that you might have a deficiency in one or more of the B vitamins. These deficiencies can lead to elevated homocysteine levels, which in turn can lead to anti-epileptic drug resistance (i.e. your anti-epileptic drug won't work as well, or work at all.)

In general, most anti-epileptic drug meds are better absorbed when the body is digesting properly.

You might want to look at the thread Seizures and eating disorders? It brings up the subject of seizures and eating disorders with lots of good advice.
