There is no scientific evidence that wanting to poop after meal indicates bowel cancer, it is not true. Wanting to have a bowel movement after meal may be a normal phenomenon, or it may be caused by irritable bowel syndrome, colitis and other diseases, if the patient has blood in the stool, change of bowel habit and other manifestations, it may be bowel cancer. Wanting to have a bowel movement after meal is not necessarily bowel cancer. If the patient eats spicy food such as chili, mustard, etc., which will stimulate the gastrointestinal tract, he/she may have the symptom of wanting to have a bowel movement after meal, which is a normal phenomenon and does not need to be treated, and it will be relieved after adjusting the diet. In addition, patients with irritable bowel syndrome may also have postprandial fullness, abdominal pain, diarrhea and other symptoms, and some patients may have the symptom of wanting to have a bowel movement after meals. In addition, patients with colitis may have symptoms such as diarrhea, abdominal pain, blood in the stool, and a feeling of incomplete bowel movement, and patients may also experience a desire to have a bowel movement after meals. If the patient wants to have a bowel movement after meal for a long time, accompanied by blood in stool, change of bowel habit, loss of weight, abdominal mass, anemia and other symptoms, it is mostly considered to be caused by intestinal cancer. If the patient wants to have a bowel movement after meals, bowel cancer is not real. Occasionally, there is no need to worry about the manifestation of wanting to have a bowel movement after meals, but if the patient often has the manifestation of wanting to have a bowel movement after meals, he/she should go to the hospital in time for systematic examination to clarify the cause of the disease, so as to avoid delaying the treatment. It is suggested that patients should have a light diet, eat less spicy and stimulating food such as chili, pepper and mustard, and make a habit of having bowel movement on time.
