hi, ive been having some problems for a few months now, and my doctor hasnt been much help. she did some tests that showed i have low potassium, low blood sugar, low iron, and anemia. she said its nothing to worry about and gave me a very vague diet plan to follow. since then, ive gotton worse, ive had a few episodes of passing out and now i dont have medical ins anymore so i need to know if this is something serious or something i can fix at home.
