What Causes Heart Palpitations And Chest Tightness While Working Without Eating?
Question: when I go 5 hours without eating then do something strenuous get racing heart with tightness in chest
Brief Answer:
Low blood sugar
Detailed Answer:
Hi,
If you do not eat for 5 hours and do strenous activity your blood sugar level will drop little further to a critical range where there is sympathetic activity that starts. With this the heart races and this is a normal physiologic mechanism.
If you are diabetic, heart disease survivor, hypertensive you need a thorough evaluation by your doctor for any new symptom like this. If not this can be a normal physiology. So you should not stay for so long without eating and cannot continue doing strenous work.
Hope this clarifies.
