(1) Etiology of insufficient intestinal beneficial bacteria: After taking antibiotics or other drugs, the beneficial bacteria in the intestinal tract are destroyed, resulting in indigestion and constipation. It is suggested that Bifidobacterium aureus be used for intestinal proliferation to prevent constipation.

(2) Causes of lack of crude fiber in diet: Eating out, eating irregularly, and having no time to take care of balanced nutrition intake often lead to insufficient intake of crude fiber food. It is recommended to eat more vegetables and coarse grains.

(3) People who don't drink enough water: they are too busy to drink water. When the intestines are dry, the intestinal contents are not easy to be discharged. Even if some people make up water, the constipation problem has not been improved. This is because the way of drinking water is incorrect. When drinking water slowly, almost all the water is absorbed into the blood and excreted through urine. It is recommended to drink more water, especially after getting up in the morning.

(4) sedentary: sedentary, lack of physical exercise, intestinal muscles become slack, and peristalsis is weakened. In addition, women's abdominal muscles are naturally weak, and the strength of defecation is small, so constipation is prone to occur. It is recommended to do more exercise, especially for the ladies in the office.

(5) People with poor defecation habits: they are busy with work, or they are pressed for time in the morning, and they don't defecate in time when they have a bowel movement. They often endure it, and the rectal sensory nerves become dull and habitual constipation occurs. It is recommended to defecate regularly.

(6) Overwork and mental stress: Overwork and mental stress will inhibit intestinal peristalsis and secretion of digestive juice, leading to indigestion and constipation. Suggest more rest.

(7)[ 1] Increased risk of intestinal cancer: dry stool is caused by too long contact between intestine and stool, and at the same time, too long contact between intestine and carcinogens in stool.
