Increase the probability of a bowel movement by several mechanisms: irritant or stimulant action on the bowel wall, bulk-forming action on the stool leading to reflex contraction of the bowel, softening action on hard or impacted stool, and lubricating action to ease the passage of stool through the rectum. Discuss the mechanisms and examples of drugs used for irritable bowel syndrome (IBS) and other conditions related to bowel movement.
Understand the Problem
The text appears to be discussing various mechanisms and drug treatments related to bowel movements and conditions such as Irritable Bowel Syndrome (IBS). It outlines different types of laxatives and their mechanisms of action, as well as warnings regarding their use. The focus is on how to increase bowel movement and manage associated symptoms.
Answer
Laxatives work by stimulation, softening, lubricant or bulk-forming actions. Examples include Psyllium, osmotic agents, and stimulant laxatives for IBS.
Laxatives increase bowel movement probability through irritant action (stimulating bowel muscles), bulk-forming action (increasing stool bulk), softening stool (making it easier to pass), and lubrication (easing stool passage). Examples for IBS and related conditions include bulk-forming agents (e.g., Psyllium), osmotic agents, stimulant laxatives, and stool softeners.
Answer for screen readers
Laxatives increase bowel movement probability through irritant action (stimulating bowel muscles), bulk-forming action (increasing stool bulk), softening stool (making it easier to pass), and lubrication (easing stool passage). Examples for IBS and related conditions include bulk-forming agents (e.g., Psyllium), osmotic agents, stimulant laxatives, and stool softeners.
More Information
Laxatives can treat constipation in IBS, chronic idiopathic, and opioid-induced constipation. They improve bowel movement by influencing stool consistency, volume, or intestinal movement.
Tips
It's common to confuse laxative types and actions. Ensure you understand how each type works and its specific use cases to avoid incorrect application.
