There are lots of things that can affect the way you surface after you donate blood. What you ate, any exercise you did, if you're dehydrated, or if you've be sick in olden times few days or even weeks. If there enjoy been any other through changes contained by your life, that can also adapt the way your body react to the loss of fluid.
Generally, blacking out is due to the a small stint of hypoglycemia (or low blood sugar). That's why they provide donors with cookies and liquid after donating.
Before you donate again, be sure that you eat in the order of 30 minutes before you shift. And make sure it's a duly well on the edge meal next to simple AND complex carbs. After you're done, sit around for a while and enjoy the pure sugar that they've laid out for you.
A few days since you go, I'd drink a few more specs of water than usual to ensure that you're not dried out. More water usually won't hurt anyone.
Good luck the subsequent time you donate. You're saving at least possible three lives!
