yesterday for cross-country, i started running a good 2 miles without problem but when i was running i felt like i was going to throw up and it was hard for me to breath. What might cause this condition if i was not dehydrated?

Hello Customer!
The nausea and shortness of breath can both be related to a sudden increase or overtraining. Also if you ate a meal within 2 hours of running or a heavy meal the stomach emptying time can slow and cause nausea. If you develop coughing/wheeing or chest pain you should see a dr. Otherwise the shortness of breath if you are not overtraining can be due to the rush of blood to the GI tract with cramping or intestinal discomfort. If not, try spacing running and eating and if you get to this point again a short walk break and then a slight easing back into running after a minute or so of walking may help. A small snack that is easy on the stomach and easy to digest 30 minutes or so can prevent hypoglycemia (which can also cause these symptoms). Half a banana, an energy gel, or some dried apples or raisins work well for most runners.
Good Luck
Hope this helps!

Too little to eat may also cause nausea with exercise as a hypoglycemic reaction. A well balanced meal 2 or so hours before exercise and a small snack if needed like the ones i mentioned is best. You can still have nausea and even vomiting even without eating (similar to a viral infection) from the impact of the running and the upset caused to the digestion process.
