Hello, I am 19 years of age. I wanted to know how I can tell the difference between Iron Deficiency or Iron Overload. I don’t have any serious symptoms but I do feel a bit fatigued and light-headed when I get up from laying down or sitting on the floor. I think it may be something with Iron because I have made some changes to my diet. Trying to eat less red meat, but still eating plenty of fish, vegetables and fruits. I have seen improvements in my body, I have less phlegm in the morning. And my face has less pimples, my nose is not congested anymore. But now its been a few days and I have noticed these symptoms I mentioned above. Am not sure what is the diagnosis, but I would like to catch it early if possible.
