Feeling sick after exercise

I am very unfit and recently started playing netball with my company. I can play for about 15 mins and then i start feeling dizzy and faint. How do i prevent this?

Hi nn

Partly related to the relative lack of fitness - remember that before this, you may not have exercised for years. So your body is not used to the exertion, and so feeling tired and dizzy is partly expected.

The other possible causes are a drop in blood sugar or blood pressure. Blood sugar is easier to solve - you just have to have something sugary to eat/drink when you play. Coke, Powerade, fruit juice will do the trick.

If it's blood pressure, it's a little trickier to know for certain - you'd have to see a doctor and have it measured before and after exercise. That's a bit of a mission, so you can also check if it goes away if you lie down with your feet up on a chair, elevated above your head.

The problem should go away, regardless of the cause. If it's blood pressure, then over time, as you get fitter, you'll get better at regulating it. If it's fitness, then you'll find it easier to play and if it's blood sugar, then simply eating or drinking solves it.

So hopefully you can overcome this quickly and start enjoying the games!

Good luck
