Tired, but the tests came back normal
Physician Poh Yu Min (Joy) · 傅瑜敏医师
Sub-health is a term used in TCM for feeling persistently below par without a diagnosis to account for it — tired, sleeping badly, catching everything going, foggy, out of sorts. It is a description of a state, not a diagnosis, and this article is mostly about keeping those two things apart.
What the word does and does not do
Sub-health names a experience. It does not identify a cause, it does not correspond to any medical condition, and being described as sub-health is not being told what is wrong with you. If it sounds like a diagnosis that is only because it is a noun; nothing has been found.
That distinction matters more here than in any other article on this site, because there is no medical diagnosis sitting alongside this one to keep it honest. Where an article about reflux can point at an endoscopy, this one has nothing to point at — and the right response to that is to claim less, not to fill the gap.
Normal results are worth having
Persistent tiredness has a long list of medical causes that are found with ordinary tests: anaemia, thyroid problems, diabetes, vitamin deficiencies, sleep apnoea, depression. Several are common and most are straightforward to treat once identified.
So if you have not had these symptoms looked at, that is the first thing to do — not because TCM cannot help you, but because a normal set of results is information you want before anyone starts explaining your tiredness with anything at all. That includes explaining it with TCM.
What a consultation covers
Sleep — when you fall asleep, whether you wake, how you feel on waking. Digestion, appetite, thirst, bowel habit. How your energy moves through the day. Temperature: whether you run cold or warm, and whether that has changed. Mood and stress. Pulse and tongue examination sit alongside the conversation.
The physician reads a pattern across those answers rather than looking for a single cause, and will describe what she finds in TCM's own vocabulary. As elsewhere on this site: those are pattern descriptions used to decide treatment, and they are not medical findings.
Please see a doctor if these symptoms have not been investigated, and particularly for tiredness that is getting steadily worse, unexplained weight loss, fever that keeps returning, night sweats, or breathlessness. Go sooner rather than later if you have felt this way for months — a long-standing symptom is not a mild one, it is one that has been given time. None of this is a reason to stop TCM treatment. It is a reason to have both, and to have the tests first.
