Most people who are mildly constipated do not need laxatives. However, for those who remain constipated after having made lifestyle changes, physicians may recommend laxatives or enemas for a limited time. These treatments can help retrain a chronically sluggish bowel. For children, short-term treatment with laxatives, along with retraining to establish regular bowel habits, also helps to prevent constipation. A physician should determine when a patient needs a laxative and which form is best.
Laxatives taken by mouth are available in liquid, tablet, gum, powder, and granule forms.
These laxatives, also known as fiber supplements, are taken with water. They absorb water in the intestine and make the stool softer. Stool softeners provide moisture to the stool and prevent dehydration. These laxatives are often recommended after childbirth or surgery. Mineral oil is the most common lubricant.
