The pronunciation of some letters is dissimilar in European Portuguese and Brazilian Portuguese, because the Portuguese is a pluricentric language.
Laxatives (purgatives, aperients) are foods, compounds, or drugs taken to induce bowel movements or to loosen the stool most often taken to treat costipation . Certain stimulant, lubricant, and saline laxatives are used to evacuate the colon for rectal and/or bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives cause diarrhoea. Laxatives work to increase the movement of fecal matter along the colon.
Bulk-forming laxatives are sometimes called fibre supplements. They increase the bulk of your stools (faeces) in a similar way to fibre. They partly work by absorbing water (a bit like blotting paper). The increase in the bulk of your faeces stimulates the muscles in your gut to squeeze faeces along and out of the body.
