Some people are to the hospital to see a doctor, but, in essence, he is treating himself, saying doctor you just tell me what to do; some people also listen to the doctor’s advice, but, he simply did not understand, on the little bird hitchhiker, a half knowledge to give up. To solve this problem to be divided into two aspects to say, one is to know how the doctor to see; the second is to understand the chronic constipation. Doctor’s visit is through the understanding of the doctor’s diagnosis and treatment of useful information on the condition. The information is firstly the symptoms (the patient’s own feelings), secondly the signs (the doctor’s examination) and finally the instrumental tests (laboratory tests, colonoscopy, radiology films, etc.). Based on this information, the doctor analyzes the possible causes of constipation, the reason for the disease (constipation is divided into several types of constipation depending on the mechanism), as well as the identification and exclusion of diseases similar to constipation (hypothyroidism, etc.) and exclusion of serious complications of constipation (colon cancer, colon perforation, etc.). Ruling out both types of disease is often the first thing doctors do, initially ruling out diseases similar to constipation (sometimes called secondary constipation i.e. constipation with a cause) and ruling out more serious complications. Because this is eliminating the danger and identifying the treatable diseases that cause constipation, the doctor is relieved, and the doctor treats the treatable diseases, and when the treatable cause diseases are well, the constipation follows. After these two types of diseases are eliminated, the doctor begins to further analyze the condition of constipation. A simple analysis of the type of constipation. In a more in-depth analysis, there are possible related causes, specific congenital factors in children, hormonal changes in pregnant women, psychological anxiety in adults, correlation with other chronic diseases, and so on. Some conditions have to meet the needs of the doctor in order to understand the diagnosis of the condition. Therefore, the patient must provide the information requested by the physician. However, often the patient does not provide the information required by the physician. For example, how long has the bowel movement been difficult, and how long has it been aggravated by laxatives. Patients just say what they think about their condition, and every day I encounter this problem in my visits, where doctors ask questions and patients ”don’t take them seriously” and ask questions that are not answers. I have provided requests for information about the condition from internet users in qq groups and online, and less than one tenth of them look or provide information as requested. What’s more, they only asked ”How should constipation be cured? ” in one sentence. It is impossible for the doctor to answer without understanding the condition. Other patients, simply do not care whether your doctor analyzes the condition and treats it in stages according to the condition for different conditions. As long as the doctor’s treatment measures he has heard of or tried, they always make a choice according to their own perception. Nor are they willing to spend a certain amount of time to understand the disease and adhere to the treatment. Of course, part of the reason is that it is more difficult for the patient to understand the reasoning of the disease.
