I am 53, very active, under 108 pounds and 5 2 . I have frequent times where I feel very empty like there is not much air/food, like my chest is light and I get slightly dizzy or light headed and feel like I don t have as much energy as usual. I still have my monthly and sometimes it is very heavy. I already know I have low iron so I take Ferrous Sequels. I don t eat cakes, ice cream, candy or any sweets because I don t like them. Not a fan of vegetables either but I do supplement them by drinking them in a smoothie. I eat healthy. I have to eat something every couple of hours to keep the feeling like I am going to faint away. Why?
