Discomfort around the navel after defecation may be caused by physiological factors, or it may be caused by intestinal cramps, gastrointestinal dysfunction, intestinal bacterial infections and other reasons. 1. Physiological factors: the patient is too hard during defecation, resulting in too much tension in the abdomen, which may cause discomfort around the umbilicus after defecation. 2. Intestinal spasm: due to improper eating, food allergy, cold abdomen and other reasons, resulting in contraction of the smooth muscle of the intestinal wall, the symptoms of discomfort around the navel after defecation. 3. Gastrointestinal dysfunction: after patients with gastrointestinal dysfunction have bacterial imbalance, bacteria multiply, affecting the body’s nutrient absorption, and the symptom of discomfort around the umbilicus after defecation may occur. 4. Intestinal bacterial infection: After the intestinal tract is infected by bacteria, it constantly stimulates the mucous membrane of the gastrointestinal tract, leading to diarrhea and post-defecation umbilical discomfort. It is recommended that patients with symptoms of umbilical discomfort after defecation go to the hospital in a timely manner to clarify the cause of the disease under the guidance of a professional physician.
