Sounds like you have a serious case of dehydration and/or blood sugar crash. Often when you're thirsty your body will also tell you you're hungry. Sugar crash would explain both hunger and light-headedness. You should talk to your doctor, maybe talk about getting fasting sugar levels (which she'll probably suggest if she thinks there's a problem), talk about any meds you're on that could interfere with moderately intense (if you're doing intense (for you) when you're not an experienced exerciser...) exercise, and generally just talk about these episodes and when they happen (be detailed about everything).
Weigh yourself before and after exercise, if you've lost weight after your workout you didn't keep hydrated during your workout.
Remember that your body doesn't figure out you've fed it for around 20 minutes so you may satisfy your hungry but not realize it for a while.
After you workout try and eat a protein or a protein and a carb (debates ahoy on which is better post-workout), even after you stop heart-elevating exercise your body is still burning calories so it's a good time to get some nutrition in anyway. Your body needs the protein to fix up the muscles you worked and the carb to replenish stored glucose, more over, your body really wants healthy proteins and carbs after you workout when it's really revved to absorb stuff. I eat more protein than carb but opinions vary about what you should eat.
My protein shake is 2 scoops of chocolate designer whey protein powder, one scoop unflavored genisoy protein powder, both added to a shaker crammed full of ice, water to mix (milk breaks me out and I'd rather use my calories else where since I'm not total squee over milk). The genisoy has 5 grams of fiber which keeps the protein from rushing out of my system, letting it absorb more and helping prevent a sugar drop.
For breakfast (or other meal) I often eat unflavored oatmeal with 1 scoop designer and some raisins added to the cooked oatmeal. A filling meal with complex carbs and protein. A meal like the above will delay stomach emptying, making you feel full longer, has many nutrients your body wants, and again with the lack of a sugar crash.
Making sure you've eaten a proper amount of calories before a workout is important. I know if I slack off on breakfast and other good things lightheaded and gross feelings are in my future during a workout. I don't like to eat before a workout, this includes the 30min before some people do but I do make sure I've had complex carbs, proteins, and a few good fats that day.
I really would talk to your doctor about it.
