If the patient has no obvious discomfort and there is no obvious abnormality in the shape and color of the stool, it is usually normal. However, if there is pus or blood in the stool, it is abnormal.
The thickness of normal stool is usually 2~4cm, but there is no uniform standard for the thickness of normal stool due to the difference of individual’s physique. If you eat less, or the diet contains less dietary fiber, the food residue produced will be less, and the stool will be relatively thin, only 1 cm thick. However, it will gradually recover after improving the diet.
Usually, as long as the patient does not have obvious abdominal discomfort, the stool is formed, the color and smell are normal, and there is no abnormal material such as pus or blood, it is usually normal.
However, if the patient’s stool suddenly becomes thinner within a short period of time and is accompanied by abdominal pain and diarrhea, nausea and vomiting, abdominal distension and other discomforts, or if the stool is not shaped and there is obvious blood or pus, it is usually not normal. At this point, gastrointestinal diseases are usually considered, such as colon polyps, anal stenosis, rectal polyps, intestinal cancer, hemorrhoids, incomplete intestinal obstruction and so on.
If the patient’s stool suddenly becomes thin and there are uncomfortable symptoms, it is recommended to consult a doctor in time to identify the cause of the disease and carry out targeted treatment.
