Tiredness and Fatigue are almost ubiquitous in our society, they also have their own acronym ‘TATT’ which means ‘tired all the time’. It is complex because of the differential diagnostics, there are many possible reasons for fatigue. In general tiredness from a Chinese Medicine perspective is a lack of energy, kidney Qi specifically. Human beings obtain fuel from food, the process of digestion changes our food into ‘us’ via a pathway involving the stomach, pancreas, liver, gall bladder, small and large intestine, and on a purely energetic level the lungs are also involved. These organs refine the qi until it can be used by the body, the fresh Qi is moved into the system of the kidneys, from there it is distributed into the whole meridian system. If there is not enough Qi, tiredness and fatigue are one result. In practice fatigue is usually a symptom of another condition.
