In the outpatient clinic often because of constipation to seek help from the doctor’s situation, but ask carefully will find that 80% of them may not be really to the point of needing medication or other help, but only the patient himself from the heart will be compared with his understanding of the normal population, self-diagnosed as constipation and forced to seek change. What is true constipation? What is the case of constipation need to consult a doctor? Here I give you a summary. What is true constipation in the clinical sense? We call it constipation when the bowel movement is less than twice a week, or when it is difficult to defecate and the feces are hard and granular, and when it is accompanied by headache and discomfort in the lower abdomen. It is important to note that many people think that having a bowel movement once a day or not having a bowel movement for two days is abnormal, but it is not. Because there are many reasons that can lead to constipation, many times because of their own eating less, or less exercise, defecation will not be so timely, this is a normal phenomenon, we do not need to worry too much. Only when the following conditions exist and the symptoms mentioned above appear, we will diagnose it as pathological constipation. First: people with endocrine and metabolic disorders such as thyroid disease and diabetes are prone to constipation. Secondly, people with central nervous system and peripheral nervous system diseases are prone to abnormalities of sympathetic and parasympathetic nerves of the intestines, which leads to defects in intestinal motility and easily induces constipation. Third: people with intestinal tumors or inflammatory diseases, the intestinal structure will also have organic changes, which is also easy to induce constipation. Fourth: people who take diuretic drugs, antidepressant drugs, anti-Parkinson’s drugs for a long time, because the side effects of drugs lead to constipation. Fifth: because of life, work and other aspects of the problem, resulting in nervousness of the crowd, due to the focus of distraction, the feeling of defecation is slow, but also easy to induce constipation. Only in the case of bowel movements produced by the five problems mentioned above may medication be needed. The doctor will take into account the patient’s specific problem. If the constipation is caused by medication, it is usually treated with laxatives; if the constipation is caused by organic effects on the intestinal structure, it will be treated with pro-dynamic medication, anti-inflammatory medication, and surgical interventions if necessary. If the constipation is caused by mental factors, the principle of “psychotherapy as the first priority, supplemented by medication as a lightweight” will be followed. In addition, constipation can also be caused by human factors such as decreased food intake, poor dietary habits, and decreased water intake. This non-pathological situation, we just need to establish a reasonable diet, eat more high-fiber diet, drink more water can be, sesame oil also has the effect of helping defecation. Sesame oil can also help with bowel movements. Increased exercise, good bowel habits, etc. are all self-treatments that can be achieved at home. Therefore, we need to have a more scientific understanding of constipation. If constipation occurs in the above five cases, we need to raise the degree of concern, and go to the hospital in time for diagnosis and treatment.
