What is the relationship between preventive health care and physical examination

To put it simply, physical examination is the most advanced and practical core link in the preventive health care system. It is equivalent to regular "safety inspections" of the body and is the core basis for all subsequent health care interventions. Without accurate physical examination results to support, preventive health care can easily become a "blind health care" without any target.

I have been working in a community public health post for almost 7 years, and I have seen too many examples of separation between the two. Last year, Aunt Zhang, who lives in Building 3, followed the trend and stocked up more than 3,000 yuan of multivitamins, liver-protecting tablets, and heart-protecting soft capsules. Her blood uric acid exceeded the standard and her liver function was mildly abnormal. After asking the nutritionist, she found out that she had a weak purine metabolism, and the dosage of B complex and liver-protecting tablets she took had long exceeded her own metabolism. She had not even done the most basic biochemical screening before, so this supplement only put a burden on her body.

Nowadays, many people hold another view. They say that if you are not sick or in pain, you do not need to have a physical examination. You can do preventive health care by having a regular schedule and eating less oil and salt. This statement is actually not completely unreasonable. The primary prevention we often refer to is daily lifestyle adjustment, which is indeed an important part of preventive health care. But the problem is that most of them There are no obvious physical sensations in the early stages of several chronic diseases. For example, in the early stages of essential hypertension, you may only feel dizzy occasionally. Most people who are infected by Helicobacter pylori do not feel it. Even in the early stages of lung cancer, you only cough twice occasionally. By the time you notice that you are obviously uncomfortable, you are often about to enter the clinical treatment stage. If we talk about prevention at this time, it is actually half a beat too late.

There are also young people who think, "I go for a physical examination every year with my work unit, so I must be doing preventive health care." This idea is actually biased. Last month, there was a 28-year-old Internet guy in our community. There were no major problems in the physical examinations at the work unit for three consecutive years. This year, the physical examination revealed that the lung nodules have reached the stage of further treatment. As for the extent of the examination, I looked through his reports from the past two years and discovered that in fact, the chest CT the year before last showed a small 4mm ground glass nodule. However, after reading the report, he felt that he was young and had nothing to do. He neither followed up as required nor adjusted his habit of staying up late and smoking two or three packs of cigarettes a day. Doesn't this mean that the role of the physical examination was not fully played?

In fact, to put it bluntly, the relationship between the two is similar to the maintenance of your family car. The physical examination is the entire vehicle test before each maintenance. If it is found that the tires are deficient and the oil needs to be changed, you have to make adjustments and maintenance accordingly. These subsequent adjustments, maintenance, and regular reviews, taken together, are complete preventive health care. You can't just do the test without adjusting the tire pressure and not changing the oil, right? On the other hand, if you don't do any testing, you just add additives and replace parts randomly, you may cause problems with the car. The two are originally tied together, and neither one will work if it is missing.
