8 year old has slightly low bp, 144 blood sugar and had a sezieure also vomited few hours prior to sezieure. What could be wrong?

Reply . If he is otherwise healthy and this was his first seizure with vomiting. Besides other things i would look for any chance of any sort of inhalant or oral intake of likely poisonous stuff, any cleaning liquids, antifreeze in the garage. Just a food for thought. Low blood sugar usually can cause seizure 144 is not low. If rest of the blood chemistry cmp is normal then look for other causes.
