The medical concept "prognosis" was first proposed by Hippocrates. He wrote a monograph called "Prognosis", which said that doctors should not only prescribe the right medicine, but also based on the understanding of the cause of the disease. Explain and predict the development trend of the disease, possible consequences and recovery. This kind of thinking is very advanced.

Hippocrates left a wealth of medical works throughout his life, 60 volumes of which have been handed down to this day, covering anatomy, pathology, various clinical diagnosis, gynecology, pediatric diseases, surgery, Diet and drug treatment, prognosis, medical ethics and many other aspects are collectively called "Collected Works of Hippocrates". His works express the idea of ??simple materialist dialectics and have been widely circulated as basic textbooks for medical teaching before the emergence of modern medicine.

Hippocrates' "Proverbs" is also widely circulated. Such as "Life is short, skills are everlasting", "Opportunities are rare, experiments are risky, and decisions are more valuable", "Unexplained sleepiness is a precursor to disease", "Sickness requires strong medicine", "Overeating is harmful to the body", "Simple and delicious The wise sayings such as "A good diet is more beneficial than a delicious but unsatisfactory diet" have a positive effect on people's health, health care, career and other aspects.
