Suddenly feeling ill/light-headed after a run...?

asked about 2 years ago | Report

I've gone from the couch to about an 8k now and have enjoyed every minute of it. But after the last couple runs, I've felt sick once I stop. I feel FINE while running, but when I get home, my stomach hurts almost like I'm going to be ill and I'm lightheaded. About 10 minutes later it passes and I feel great the rest of the day.

I have noticed that while running intervals that sometimes I start to feel this way (light-headed/ill) during the walking periods, after running well.

So what could this be? Am I dehydrated? Not having enough nutrients? Something else?

Each day before a run, I have a breakfast of 3 eggs, toast, OJ and a multivitamin. And I've been running in cold or warm weather, nothing hot.

  • There could be a lot of things that would cause this.

    Are you stopping abruptly and not doing any sort of stretching or cool-down after your run? Are you just jumping onto the couch or laying on the floor? That'd definitely give your body a quick shock and cause that kind of reaction.

    Light-headed during intervals is completely normal. It means that your blood is dispersing more towards your limbs than your brain, and thus, causing you to have a lack of oxygen to the knowledge box. Make sure you keep moving (at least slowly) in between your intervals.

    Always, always, always make sure you're hydrating throughout the day!
