Laxatives are substances that promote bowel movements. They are commonly used to treat constipation, a condition characterized by infrequent or difficult passage of stool. Laxatives work through various mechanisms, including increasing the bulk of the stool, softening the stool, or stimulating the muscles of the intestines to contract.

There are several types of laxatives available. Bulk-forming laxatives, such as psyllium or methylcellulose, absorb water in the intestine to create a larger, softer stool that is easier to pass. Osmotic laxatives, like polyethylene glycol or magnesium citrate, work by drawing water into the colon from surrounding tissues, which softens the stool. Stimulant laxatives, such as senna or bisacodyl, increase intestinal motility by irritating the intestinal lining or stimulating nerve endings. Stool softeners, like docusate sodium, work by allowing water and fats to penetrate the stool, making it softer and easier to expel.

Laxatives are generally intended for short-term use. Prolonged or excessive use can lead to dependency, electrolyte imbalances, and other health complications. It is important to consult a healthcare professional before using laxatives, especially if you have underlying medical conditions, are pregnant or breastfeeding, or are experiencing persistent constipation. Lifestyle modifications, such as increasing fiber and fluid intake and regular physical activity, are often the first-line approach to managing constipation.
