What are the types of laxatives?

There are various types of laxatives, primarily categorized into three groups: stimulant laxatives, bulk-forming laxatives, and osmotic laxatives. Stimulant laxatives such as bisacodyl and senna stimulate intestinal motility to accelerate bowel movements and are suitable for occasional constipation. Bulk-forming laxatives like psyllium and psyllium husk utilize their water-absorbing and swelling properties to increase the volume of intestinal contents, thereby promoting defecation, making them suitable for long-term management of constipation. Osmotic laxatives such as polyethylene glycol and mannitol work by increasing water content in the intestinal lumen, helping to soften stools for easier elimination. Lactulose, another osmotic laxative, offers effective constipation relief with a relatively gentle action. In daily care, maintaining adequate hydration and consuming a high-fiber diet are crucial for promoting intestinal health. It is recommended to eat more fruits, vegetables, and whole grains to increase dietary fiber intake, which helps maintain regular bowel movements. If constipation persists or is accompanied by severe abdominal pain, vomiting, or other concerning symptoms, prompt medical consultation is advised for necessary evaluation and treatment.
