Hey sami_1982, how are you doing?
Other factors such as hypoglycemia (low blood sugar), which is a diabetic reaction, may cause seizures. A person may have a seizure disorder (epilepsy) and require medications.
The problem is especially pertinent to individuals with diabetes, whose blood glucose levels can fluctuate widely over the course of a day, as a result of intercurrent illness, variations in insulin levels, or other metabolic factors.
For excellent patient education resources, see emedicine's diabetes center. Also, visit emedicine's patient education article, low blood sugar.
Best wishes,
