A medical syndrome – for example Irritable Bowel Syndrome – is a recognisable set of symptoms without an establish biological cause. In the case of Irritable Bowel Syndrome , for instance, your bowels don’t work properly, maybe with diarrhoea or constipation or abdominal pain, or all of these, but there is nothing obviously wrong with them s that any conventional medical investigation can detect. There is no inflammation to speak of, or anything like that. But you still have the symptoms. Hence it is a syndrome. Another one of course is Chronic Fatigue Syndrome where you are really very low on energy, often crippling so, and yet there is nothing that can be found by conventional medicine – blood tests and so on – that can explain it.
