for the past year ive suffered with small dizzy spells lasting only for a second ive had high bp and always put it down to that, but now my bp has retured to around 120/70 and it still occurs every once in a while ive been to the docs 4 times and have had an ecg but no problems show up. im now wondering if it could be something missing from my diet i get around 5-600 grams of carbs a day so kinda ruling out low blood suger,any1 got any ideas or advice would be appreciated
