A colonoscopy is a test that screens a patient for colon cancer by inserting a tiny video camera into the rectum so the doctor can see the condition of the colon.
Preparation
Colonoscopy preparation, according to Dr. Timothy Moynihan of the Mayo Clinic, is to clear out fluids and stool from the colon.
Laxatives
The day before the procedure, the doctor will have the patient take laxatives, being careful to suggest the correct one, as some laxatives can't be used by those with heart or kidney disease.
Liquid Diet
The patient is allowed only nonalcoholic, clear beverages to drink such as broth, juice, water, black coffee or tea. No solid foods and no red liquids are allowed in the 24 hours prior to the procedure, according to Dr. Moynihan.
Ask About Medications
Medications containing iron or iron pills may need to be stopped because iron can color the lining of the colon.
Age for Screenings
Mayo Clinic advises colonoscopy screenings starting when the patient is 50 years old. Consistent negative screenings mean that the patient can usually stop the procedure at age 75.
Goal
Having regular colonoscopy screenings that test and remove colon polyps will help prevent colon cancer.
