Stimulant laxatives are medications designed to promote bowel movements by stimulating the muscles in the intestines. They work by increasing the contractions of the intestinal walls, which helps move stool through the digestive tract. Common examples include bisacodyl and senna. These laxatives are often used to treat constipation, especially when other methods, like dietary changes or bulk-forming laxatives, are ineffective. However, they should be used with caution, as overuse can lead to dependency or disrupt normal bowel function. Always consult a healthcare professional before starting any laxative treatment.
