Laxatives are substances used to relieve constipation by promoting bowel movements. They work in various ways, such as softening stool, increasing intestinal contractions, or adding bulk to the stool. Common types include stool softeners, bulk-forming agents, and stimulant laxatives. While laxatives can be effective for occasional use, they should not be relied upon for long-term relief. Overuse can lead to dependency, where the body becomes unable to function normally without them. It's important to consult a healthcare professional before using laxatives, especially for chronic constipation or underlying health issues.
