Hey I m c.n.a worker work long hours and hardly eat normal balanced foods. I realized my heart would just start beating fast at times and my b/p has been high and I checked it now it is 145/106. Now I do work ten hour shift on two days then 48 hours on other two but I eat or snack on my job because I can t leave. Wat can I do and my pulse read 91 . I sometimes feel energetic but also like im very nervous or something it doesn t mean I stress. I was sleep and woke up with a rush of fast heart rate nervousness and felt like my heart was gona pound out me. I do know I don t get much sleep and from not eating fully cooked meals either. I make my clients meals while I m here but don t eat as much as I feed them . I never had issues with anything before and I just needed to know at times so I called ambulance one time they checked me and said my b,/p was a lil high that I was a lil dehydrated and my heart was 150 bests per min I got my heart and lungs checked to and everyone saying I m good no signs of nothing even had blood taken and it was a negative .is it cause I need more food or anything else.
