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.
The doctor may advise you to take laxatives if you have medical conditions that may be worsened by straining. These conditions include heart disease, hemorrhoids and hernia rupture. Laxatives are also used to evacuate your bowel before you undergo lower abdominal medical procedures such as colonoscopy. Oral laxatives should be taken one or two hours after meals. Different types of oral laxatives include bulk-forming laxatives, saline laxatives, lubricant laxatives and stimulant laxatives. Oral laxatives should be taken after meals with a full glass of cold water or juice, according to Drugs.com.
