Nowadays, the concept of “treating the untreated” is very popular. This concept comes from a saying in the Yellow Emperor’s Classic of Internal Medicine: “A sage does not treat the sick before they get sick”. This means that a master can detect the signs of a disease in a person who has not had an attack, and then intervene in advance. For example, when the magpie met with the Duke of Cai Huan, he said that the ruler had a disease in the coup, and he was afraid that it would be deep if he didn’t treat it, and then the Duke of Cai Huan said, “I have no disease! In fact, in ancient times such opportunities were rare, because there were few experts, and moreover, for various reasons, it was not always possible to see the problem. However, it is different nowadays, we have modern and advanced instruments and equipment to check everything from the blood flowing in our body to the brain contained by the hard skull. In many diseases, in the beginning stages, the patient has no symptoms. For example, the most common is diabetes. How many patients, when their blood sugar rises, have no clinical symptoms at all. The ancient people relied on symptoms to diagnose, no symptoms, is “not yet sick” ah. However, we have modern medical examination, if we find elevated blood sugar, we immediately change our habits, improve exercise, moderate diet, if the right measures, positive response, will greatly delay the drug intervention time, or even completely unnecessary drug treatment, this is the treatment of the disease. Not every fatty liver patient has pain in the right side of the rib cage, some have no symptoms, but if we check the ultrasound, we will find this problem, we will further check the blood lipids, ask the cause of the patient, and then target to restrict diet, limit alcohol intake, increase exercise, and think of various countermeasures, which is the treatment of the disease. These routine tests like ultrasound, biochemistry, ECG, chest X-ray, urine and stool are not expensive, but through these tests, we can get useful information before our body has any signs to guide our next health care or treatment in a targeted way, which is the cure for the untreated disease, and if we can have regular medical checkups, we will all be saints.
