Yes, Thank You. I've Been Having Dizzy Spells Every Couple

Yes, thank you. I've been having dizzy spells every couple of days at various times throughout the day. Sometimes when I'm home doing daily tasks, today while out snowshoeing. Today, it is accompanied by a tingling tongue. Just called doctor's office and have an appointment Friday. Wondering if it's blood sugar related. I am very hungry all the time. I eat small snacks all throughout the day. I am 46, 120 pounds, low blood pressure, fit and healthy.
