I've been feeling very weak, fatigued, sometimes dizzy, and I've noticed I've lost a little bit of weight. I have had a slight fever and I have been urinating very frequently, even though I have had bladder infections, and then it progressed to a kidney infection. I still don't think that is problem. I am now 26 yrs old, but when I was 21 a doctor told me that I have low iron in my blood, I haven't been taking iron tablets as frequently as I should, so could this be the problem?
The symptoms you present with can have many causes. Simple blood and urine tests would be able to answer some of your main concerns very easily and definitively. I would recommend that you see an Internist or Family Physician to sort this out.
