Organs systems suffer fatigue. Whether due to stress, trauma, diet, lifestyle, acute illness, bad luck…. Conventional medicine assumes the body returns to 100% without assistance (they don’t even consider diet as necessary assistance). This is a flawed and outdated model of medicine. Before disease of the body the organs systems do not function optimally and set the stage for conditions to worsen, generally symptoms are just indications of the organs systems not functioning optimally, like lights on your cars dash. An engine is not defective or damaged because you have not replaced your oil filter, the oil filter is just not capable of functioning optimally and “symptoms” arise.
