What is the treatment for impacted stool?

1. High-fiber diet

2. Stool softeners

3. Phosphate enema

4. Oral laxatives

The correct answer is: Phosphate enema

The treatment for impacted stool commonly involves the use of a phosphate enema, which is specifically designed to help break down and mobilize the hardened stool that is obstructing the bowel. Phosphate enemas work by introducing a saline solution into the rectum, which helps draw water into the bowel, softening the stool and promoting bowel movements. This method allows for quicker relief from constipation and is particularly effective in cases where the stool is severely impacted. In contrast, while high-fiber diets, stool softeners, and oral laxatives can be beneficial in preventing constipation and managing milder cases, they may not be as effective for immediate treatment of stool impaction. High-fiber diets and oral laxatives typically require time to produce results, and stool softeners may not adequately address the problem of hard, impacted stool. Therefore, in situations of significant impaction, the phosphate enema is often the preferred choice to provide prompt relief and resolve the blockage.
