I've been eating a vegan diet for a couple of weeks. I just recently starting getting pretty light-headed. I have really low blood pressure (due to hypoglycemia and anemia), but I haven't had a problem with it for quite a while. I'm eating perfectly fine, plenty of iron (for the anemia) and limited sugar (although it's not low blood sugar I'm experiencing, anyway). I eat regularly. I just don't know what it is? I've been a vegetarian for years and I haven't had any issues. Am I missing/forgetting about some nutrient? Or do you think that the switch to a vegan diet just eliminated a lot of my salt intake? I'm bewildered. Any thoughts?
