Heroes Not Zombies

You know if you cut yourself that, in the vast majority of cases, the cut will heal itself just if you keep the area clean. You know how, if you break a bone, that the fracture never heals without the body using its ability to knit back together the broken edges of the bone (sometimes you need something to hold the edges together – a plaster, nails or a plate – but the actual healing of the bone is done by the body). Well, in fact this is what all living organisms do – they self-heal, self-repair, and self-organise.

One model for living organisms is a “complex adaptive system” (search that term on this site and you’ll find several articles I’ve written about it). Complex adaptive systems have a key, core characteristic – they adapt. Self healing is an aspect of adaptation.

Yet, in Medicine we rather take self-healing for granted. We know that nobody recovers from anything without self-healing. We need the body’s abilities to repair, and to adapt and grow, in order to heal. Every single time. But how many treatments, specifically, how many drugs do we use which are developed to target the capacity to self-heal? How many drugs directly stimulate or support the natural processes of self-healing? I don’t know any. Instead we direct our treatments “against” – we use lots of “anti”s – antidepressants, anti-inflammatories, anti-hypertensives, antibiotics etc etc – you get the idea – and hope that in the background the body will self heal. I don’t mean these anti drugs are useless. Clearly they are not. In many cases they can rescue someone suffering from a life threatening episode of illness. But they aren’t enough. We also need to stimulate and support the natural systems of self healing and repair.

What are they?

Well, largely, they are environmental, psychological and social. We need light, clean air, clean water, nutritious food, shelter. We need hope and encouragement. We need to feel cared for and loved. We know that forests can help us heal. We know that time spent in natural environments can help us heal. We know that music, and art, and stories can help us heal.

So do we need drugs? Well, we do. The thing about self-healing is that it is limited by natural biological limits. We are mortal beings. None of us will live forever, and none of us will go through life without experiences diseases and illnesses. Drugs can help us by easing symptoms, addressing imbalances, and countering pathologies. But Medicine is, and always has been, more than just drugs.

But there is something else about self-healing that we should pay attention to and that is…..in common with all forms of adaptation, it is unpredictable at the level of the individual. Sometimes we pretend that all we need to go is a give an “evidence based” treatment and the outcome can be assured. That’s not the case. There is no treatment which produces the same outcome time and time again, in patient after patient. Adaptation teaches us to accept uncertainty. It teaches us to stick with a patient, to follow through and follow up, because only time will tell whether or not the treatment is proving to be useful or not for this person.

And there’s the other key lesson for Medicine from the science of adaptation and self-healing – patients do better when they experience continuity of care.

Over time, we have to adapt our treatments and our care, as the individual patient adapts to the changes brought about by the disease or injury which has made them ill.

It’s good to learn how to deal with uncertainty, because life isn’t predictable.
