is feeling faint when hungry a symptom of not enough iron?
It could be a symptom of low blood sugar, dehydration or other things. It's good to see a doctor if you can. If not, find someone who had diabetes and ask them if you can use their blood tester next time you're feeling faint, to test your blood sugar and see if it's low. Each test uses a new strip, so there's no chance of contamination. If your blood sugar tests OK, you can try drinking more liquids. Try to get at least 64 ounces per day. Any less than that and you can feel faint, especially when standing suddenly from a sitting or lying position. One's iron level is pretty easy to test for and I don't think it costs much, so you should be able to have it done even if you don't have insurance. If you end up having to take an iron supplement, I recommend either carbonyl iron or heme iron polypetide. These types of iron are much easier on your digestive tract, causing much less or no gas and constipation. Heme iron polypeptide is the best, but it's quite expensive. Carbonyl iron is almost as good, and cheaper.
