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.
This is a very simple question to answer. Both stool softeners and laxatives will help move waste out of your body, the only difference between the two is one lubricates and the other moistens. Laxatives will lubricate your intestines and feces. Stool softeners will moisten the fecal matter and make it easier to move.
