Seeing a doctor when sick is a truth that even children know. But now many people have developed a strange "habit" of searching online when their bodies are not feeling well.   However, as "self diagnosis" becomes a habit, there are more and more cases of "diagnosing the wrong disease" and "taking the wrong medicine", and eventually cases of worsening or even death occur. Therefore, it is time to sort out the various controversies about "self diagnosis". 1、 Dr. Wang recently had a dispute with a patient through a search engine self diagnosis: the cause was that a patient had symptoms of hematuria, and the number of red blood cells in the urine exceeded the standard. Dr. Wang said to do a CT scan first to see the results. However, the patient insisted that he might have bladder cancer and needed cystoscopy, because "he had checked on Baidu and his symptoms were exactly the same as mine". Dr. Wang got angry at the time. Is it really my profession as a doctor? Or is it your 'someone said online' profession that emerged somewhere? The final examination result showed that the patient's hematuria was caused by kidney stones. She said that nowadays patients always like to search online, and even directly ask doctors for diagnosis and medication when seeking medical treatment, thinking that they are more professional than doctors. On Weibo, doctors often complain that their daily job is to fight with "professionals" who come out of Baidu without knowing where. Many patients, after "Baidu" their own condition, feel that they understand it very well, and even instruct doctors to treat it this way, requesting or not to use certain drugs, which is mostly unreliable. Doctors actually have an instinctive aversion when faced with this situation. Many doctors directly say on Weibo, "What we have learned for many years is not something you can find in just one minute on Baidu." Indeed, in the era when search engines such as "Baidu" are widely used, many people may have formed the habit of "Baidu" as their first reaction when they feel uncomfortable. Looking at what is said online, "seeking medical treatment on Baidu" has become a daily habit for many people.     The report mentioned that whenever doctors see patients with swollen cervical lymph nodes, their first reaction is that it is caused by viral or streptococcal infection. But if you search online for 'neck lymph node enlargement', there are also websites that introduce lymphoma and leukemia to you in the search results. Relying on the internet for blind self diagnosis, patients must first search for medical information, always thinking of the worst-case scenario. However, this kind of online self diagnosis behavior not only has a high possibility of self misdiagnosis, but also brings serious problems to doctor-patient communication. Moreover, the scariest thing about self diagnosis through search engines is not the unprofessional answers found in the search, but the difficult to distinguish true and false medical advertisements that are placed using patients' trust in online searches. With the popularity of "online self diagnosis", it has attracted many unscrupulous vendors to join in. The recently sensational "Weizhizi Incident" has fully exposed the terrible secrets of this industry. Behind these online information, there are often large interest chains that need to be cautious. 2、 If self diagnosis on medical websites is not professional enough, are some medical websites offering "self diagnosis" and other services professional enough? The author personally experienced some self diagnosis services on certain websites, which are complete human diagnostic maps that can define the scope of diseases by clicking on different parts of the body and provide different treatment plans. For example, this "self diagnosis divine diagram" circulating on the internet points out the organs referred to by pain in some parts of the human body. However, such a popular "self diagnosis treasure book" has been met with cold water from medical professionals. Experts say that the illustrated pain areas and corresponding organs have some scientific basis, but they are relatively rough and one-sided. It can be used as a concept popularization, but it cannot be used for self diagnosis. Many people may have the same symptoms, but they may have completely different illnesses. Even for the same disease, different people may exhibit different symptoms and signs, which is not only based on a vague data judgment to provide diagnostic results, but also to recommend drugs. This requires professional doctors to use rich hospital knowledge, clinical experience, and auxiliary measures such as blood tests and imaging examinations for diagnosis. If patients blindly self diagnose based solely on the prompts of a picture, it is likely to lead to misdiagnosis, especially on such seemingly "professional" platforms. Developing such functions requires even more caution and careful consideration. 3、 Due to the diversification of channels for purchasing medication in mobile healthcare, the phenomenon of "self diagnosis and prescribing medication" for some serious diseases is not uncommon. According to surveys, there are serious misconceptions about medication safety in China, and drug damage accidents caused by unsafe medication have been on the rise every year. The incidence of adverse reactions in children's medication is about 10%, and in newborns it is as high as 20%. Many media outlets have reported on patients blindly searching for drugs online, leading to severe allergies, even shock and coma after taking them. Blind self diagnosis has given rise to blind buying and medication, and this series of serious consequences ultimately leads to physical damage, sometimes irreversible. Therefore, we do not encourage patients to prescribe, buy medicine, or treat themselves based on the results of online self diagnosis. People without medical knowledge often cannot diagnose and treat diseases through online self diagnosis, which can lead to misdiagnosis, mistreatment, and even life-threatening situations. Does this mean that one must go to the hospital for diagnosis and treatment when sick? The currently emerging mobile healthcare provides a different solution. At present, mobile medicine not only covers a platform with comprehensive functions such as consultation and health management, such as Chunyu Doctor, Ping An Good Doctor, and micro consultation, but also extends to more sophisticated vertical fields, such as Kangda pre diagnosis, which specializes in maternal and infant health consultation and management, sugar doctors who manage diabetes, and "Meiyou", which manages women's menstruation. Thanks to the development of mobile Internet, now, users only need to download an app on their mobile phones, and then they can go home and see doctors face to face on their mobile phones. Especially for some common diseases, such as colds, coughs, dizziness, headaches, mild discomfort, or daily management of chronic diseases, there is no need to go to the hospital to register and queue up, nor do you need to pay. You can directly consult a doctor through your mobile phone. This not only saves time and economic costs, but more importantly, it can effectively avoid blind self diagnosis and medication. Through communication with doctors, targeted treatment can be provided to reduce risks and achieve the goal of "scientific self diagnosis". A home environment with good network conditions provides inherent advantages for the use of mobile medical apps, and pharmacies, as a life scene that the public cannot do without self diagnosis and drug purchase, are facing the current situation of less than 20% of licensed pharmacists in hundreds of thousands of pharmacies in China. Therefore, the layout of mobile medical pharmacies is the trend. The micro medicine invested by Tencent released the "Wuzhen Internet Hospital+Pharmacy Cooperation Plan" in March this year, which will establish 1 million reception points of Wuzhen Internet hospitals nationwide. It is understood that at present, the micro medical Internet hospital has cooperated with the First Sound Zaikang and the People's Pharmacy, using the offline pharmacy of the former as the reception point of the network hospital. Alibaba Health has joined forces with 65 chain pharmacies including Baijia Huisuhe, Deshengtang, and Kangaido to establish the "China Pharmaceutical O2O Pioneer Alliance", with the goal of establishing a "network hospital+pharmacy" model. Through the Alibaba Health network hospital platform, it provides "one minute clinic" online medical consultation services for pharmacy stores under the jurisdiction of members of the alliance. While Tencent and Alibaba are aggressively entering, there are also companies that began quietly laying out in the field of chain pharmacies more than two years ago. Founded in 2014, FuDun Technology has established a "Micro Consultation" remote medical service system with micro consultation terminals installed in pharmacies and a self built team of over 500 physicians and pharmacists as its core. The system covers grassroots communities with a wide range of chain pharmacies as its touchpoints, providing medication and health consultation, remote prescription review, remote online real-time consultation, electronic prescription circulation, and other services to the general public within the coverage area of pharmacies. It has built a comprehensive health management service platform that covers self diagnosis of minor and chronic diseases, pre hospital consultation triage registration, in-hospital online report collection, postoperative rehabilitation, and chronic disease management. Before purchasing medicine for diagnosis and treatment at a pharmacy, the public can consult with practicing doctors in the background through a micro consultation terminal to see if the medicine is targeted. After consultation, you can scan your phone to take away the consultation and other related medical records. Online self diagnosis, although seemingly convenient, is prone to misdiagnosis due to the complexity of information sources and the lack of medical knowledge among patients themselves. Although buying medicine independently provides convenience for the people, accidents of accidental ingestion and poisoning often occur due to a lack of scientific knowledge about medication.

Health and medical care are crucial to personal safety, and its importance cannot be overemphasized. Even if you cannot go to the hospital due to busy work or other reasons, in today's highly developed mobile network, installing a mobile medical software on your phone or consulting a doctor through relevant devices in a pharmacy before purchasing medication for diagnosis and treatment is also a good choice.
