laxatív

Laxatives are substances that facilitate defecation. They are used to treat constipation and to relieve fecal impaction. Laxatives can work in several ways, including increasing the frequency of bowel movements and improving the ease of passing stools.

There are various types of laxatives. Bulk-forming laxatives, such as psyllium, work by absorbing water in the intestine and swelling, which helps to soften and enlarge the stool. Stool softeners, like docusate sodium, add moisture to the stool, making it softer and easier to pass. Stimulant laxatives, such as senna or bisacodyl, work by causing the intestines to contract, which helps to move stool through the colon. Osmotic laxatives, like polyethylene glycol or magnesium citrate, work by drawing water into the colon from surrounding tissues, which softens the stool and increases bowel activity.

Laxatives are generally considered safe when used as directed. However, overuse or misuse can lead to side effects such as abdominal cramping, bloating, nausea, and diarrhea. Chronic use of stimulant laxatives can potentially lead to dependence, where the bowel becomes reliant on the medication to function. It is important to consult a healthcare professional before starting any laxative regimen, especially if you have underlying medical conditions or are taking other medications. They can help determine the appropriate type and dosage of laxative for your specific needs and advise on the safest way to use them. Dietary changes, increased fluid intake, and regular exercise are often recommended as initial steps for managing constipation before resorting to laxatives.
