Products for quick constipation relief include bulk-forming laxatives for everyday use to increase fiber intake, lubricant laxatives to make the stool slippery, and osmotic laxatives to move fluids through the intestines, explains WebMD. Stool softeners also push fluid through the intestines to prevent strain during bowel movements.
Stimulant laxatives can provide quick constipation relief because these products cause the intestinal muscles to contract, ultimately pushing stool out, according to WebMD. Saline laxatives add water to the stool to ease the process of bowel movements. Patients should not use laxatives as a long-term solution and should consult with a physician to determine appropriate and safe use.
