Why does my stool always feel incomplete after defecation?

　　The sensation of incomplete bowel movements may be caused by an unreasonable diet structure, lack of physical activity, poor defecation habits, colitis, hemorrhoids, and other factors. Management should be tailored according to different situations. It is recommended to seek timely medical advice and undergo examinations to determine the cause, then follow medical instructions for appropriate management.

　　1. Unreasonable diet structure: Insufficient intake of dietary fiber and excessive consumption of refined foods in daily meals can lead to slow intestinal peristalsis, small and dry stools that are difficult to expel, causing the feeling of incomplete evacuation. Adjust the diet by increasing intake of high-fiber foods such as whole grains, vegetables, and fruits (e.g., corn, celery, apples) to promote intestinal motility and improve bowel movements.

　　2. Lack of physical activity: Prolonged sitting and insufficient physical activity can cause relaxation of the intestinal smooth muscles and weakened peristaltic ability, leading to prolonged stool retention in the intestines and causing incomplete defecation. Develop a habit of regular exercise, aiming for at least 150 minutes of moderate-intensity aerobic activity weekly, such as brisk walking or jogging, to stimulate intestinal motility and aid defecation.

　　3. Poor defecation habits: Frequently suppressing the urge to defecate can reduce rectal sensitivity and weaken the defecation reflex. Inattention during defecation and prolonged sitting on the toilet can also affect normal bowel movements. Cultivate good defecation habits by establishing a regular schedule for bowel movements daily, avoiding suppression of the urge to defecate, limiting defecation time to within five minutes, focusing attention, minimizing external distractions, and establishing a normal defecation reflex.

　　4. Colitis: Often caused by infections with pathogens such as bacteria, viruses, or parasites, unhygienic diets, or imbalances in intestinal flora, leading to intestinal inflammation. Inflammatory irritation of the intestinal mucosa results in disordered intestinal motility, causing symptoms such as abdominal pain, diarrhea, and tenesmus. Patients can follow medical advice to use medications like Norfloxacin Capsules, Enteritis Ling tablets, or Smectite Powder to alleviate symptoms.

　　5. Hemorrhoids: Hemorrhoids form due to congestion, swelling, and enlargement of the venous plexus in the anal canal or lower rectum. Larger internal hemorrhoids or prolapsed external hemorrhoids may block the anus, hindering stool passage and causing a sensation of incomplete evacuation. This is often accompanied by symptoms such as rectal bleeding, anal pain, and itching. Patients may follow medical instructions to use medications like Ma Ying Long Musk Hemorrhoid Ointment, Compound Alginic Acid Esters Suppositories, or Sophora japonica Pills to relieve discomfort.

　　In daily life, it is recommended to drink adequate amounts of water, maintain cleanliness and dryness in the anal area, and avoid prolonged sitting or standing.
