Laxatives are substances that help stimulate bowel movements and relieve constipation. They work by increasing the amount of water in the intestines, softening stool, or speeding up the movement of waste through the digestive tract. Common types of laxatives include bulk-forming agents, stool softeners, and stimulant laxatives. While laxatives can be effective for occasional constipation, they should be used with caution. Overuse can lead to dependency, where the body becomes reliant on them for regular bowel movements. It's important to consult a healthcare professional before using laxatives, especially for long-term use.
