Exhaustion is the single most common complaint that walks through my door. Not occasional tiredness after a long week, but a bone-deep depletion that shows up every afternoon, every evening, sometimes all day long. Most women reach for coffee to push through it, and for a while that works. Then it stops working, the crashes get worse, and a string of doctor visits turns up nothing but normal labs.
Here is what I want you to know before anything else: fatigue is not a personality trait, and it is not simply what happens as you get older. If aging alone caused fatigue, every person the same age would feel equally drained, and that is never what I see in practice. Fatigue is data. It is your body telling you that something specific and fixable has gone wrong.
