Regularly taking laxatives under a doctor’s supervision can promote bowel movements and likely diarrhea, but usually not persistent diarrhea. Laxatives themselves are designed to relieve constipation symptoms and promote bowel movements. Common laxatives are volumizing, stimulating and lubricating.
1. Volumetric laxatives: such as lactulose, dietary fiber, etc., in the small intestine is not absorbed, increase intestinal volume and keep the stool wet and soft, have a good laxative effect.
2. Stimulating laxatives: anthraquinone glycosides and other substances in the intestinal tract are decomposed, resulting in anthraquinone can promote colonic propulsive peristalsis, promoting defecation.
3. Lubricating laxatives: liquid paraffin, glycerin, etc., are not absorbed by the intestinal tract, lubricate the intestinal wall and soften the feces to promote defecation.
All of the above medications should be used under the guidance of a doctor to avoid self-medication.
