Are Laxatives the Right Solution for Constipation?
Published: Feb 11, 2024
Laxatives can offer relief for constipation, but not all are created equal. This article uncovers the different types and their effects.
Bulk-Forming Laxatives: The Natural Choice
Bulk-forming laxatives like psyllium and methylcellulose imitate dietary fiber by absorbing water and making stools softer and bulkier. These are often the first choice due to their natural action and minimal side effects. However, they may not be suitable for those with slow transit constipation.
Osmotic Laxatives: Drawing in Relief
Osmotic laxatives, such as polyethylene glycol (PEG), work by drawing water into the intestines to increase stool frequency. They are effective but should be used with caution in people with renal or cardiac issues to avoid electrolyte imbalances. Their widespread use is due to their effectiveness in improving stool consistency.
Stimulant Laxatives: Quick and to the Point
Stimulant laxatives like bisacodyl and senna speed up bowel movements by increasing intestinal activity. These are generally used for short-term relief and can be effective as rescue therapy. Long-term use is still being studied, but current evidence does not show harm to the colon.
