There is individual variability in bowel patterns. If you have less than 3 bowel movements per week, you are constipated, and if you have more than 3 bowel movements per day, you have diarrhea. Generally, it is normal to have 2-3 bowel movements per day or 1-2 bowel movements per day. At the same time, we also need to observe the nature of the stool and the presence of abdominal discomfort to make a comprehensive judgment. Usually, there are obvious individual differences between healthy people on the issue of defecation, mainly related to physical fitness, living habits, dietary habits and other factors. According to relevant information, under normal circumstances, the human body 2~3 times a day defecation, 1~2 days defecation once is normal. However, if the number of bowel movements is less than 3 times per week, you need to consider constipation, and if the number of bowel movements is more than 3 times per day, you need to consider diarrhea. There are many clinical reasons for abnormal bowel movements, which may be caused by improper diet, irritable bowel syndrome, peptic ulcer, dyspepsia and other diseases. At the same time, we also need to observe the nature of the stool, if it is fecal pellet-shaped stool suggests that insufficient water intake or dry stool constipation exists. If the stool is thin or the surface is mixed with mucus and pus and blood, also consider the possibility of inflammation. In daily life, we need to rationalize the diet, develop good bowel habits, if there are abnormal bowel movements, should go to the hospital in a timely manner, so as not to delay the condition.
