Laxatief

Laxatief is a term derived from the Latin word "laxativus," which means "loosening." It refers to substances or medications that promote bowel movements by softening the stool and stimulating the intestines. Laxatives are commonly used to treat constipation, which is characterized by infrequent or difficult bowel movements. They can be classified into several categories based on their mechanism of action:

1. Stimulant laxatives: These work by increasing the activity of the intestines, leading to faster transit of stool. Examples include senna and bisacodyl.

2. Bulk-forming laxatives: These add bulk to the stool, making it easier to pass. Examples include psyllium and methylcellulose.

3. Saline laxatives: These work by drawing water into the intestines, softening the stool. Examples include magnesium citrate and polyethylene glycol.

4. Osmotic laxatives: These work by drawing water into the intestines through osmosis. Examples include lactulose and polyethylene glycol.

5. Emollient laxatives: These soften the stool by coating it with a slippery substance. Examples include mineral oil and glycerin suppositories.

Laxatives should be used with caution, as overuse can lead to dependence and other side effects. It is important to consult a healthcare provider before starting any new laxative regimen. Additionally, laxatives should not be used to treat conditions other than constipation, as they may not be effective and could potentially cause harm.
