Bowel preparation protocol initiated to ensure complete cleansing for accurate diagnostic visibility.
GI specialist performs colonoscopy with sedation support and direct visualization of the colon.

Personalized care plan created based on findings, history, and long-term digestive health strategy.
Flexible sigmoidoscopy may show hemorrhoids, inflammation, ulcers, polyps, bleeding sources, or other lower-colon changes. Follow-up depends on the finding and whether tissue samples are taken.
Colonoscopy prep helps your gastroenterologist see the colon clearly during the procedure. It usually includes temporary diet changes, a bowel-cleansing medicine, medication review, and planning for a responsible adult to drive you home after sedation.
GastroDoxs will provide detailed prep instructions before your colonoscopy. Follow those instructions closely, and call the office if you are unsure about what to eat, when to take your prep, or which medications to adjust.
Watch this overview in the bottom half of the page, then follow the written instructions from your GastroDoxs care team for your exact prep timing, medication guidance, arrival time, and transportation plan.

You can expect a symptom review, medication and health-history check, preparation confirmation, the lower-colon exam if scheduled, recovery guidance, and discussion of next steps.
Preparation may include diet changes, enemas, or medication instructions. Follow the exact instructions from your care team, because prep can vary by reason for the procedure.
It may be performed when symptoms suggest a lower-colon or rectal source, such as rectal bleeding, mucus, persistent diarrhea, rectal pain, or inflammation seen on prior testing.
Coverage depends on your insurance plan, medical necessity, referral rules, benefits, and deductible. The office can help confirm the information needed for coverage review.
The clinical setup may be similar, but flexible sigmoidoscopy focuses on the rectum and lower colon. Colonoscopy evaluates the entire colon and often requires broader bowel preparation.
Prompt evaluation is important for rectal bleeding, worsening diarrhea, unexplained anemia, severe rectal pain, mucus with stool, or ongoing lower abdominal pain.
A gastroenterologist commonly performs flexible sigmoidoscopy. The procedure may also involve nurses, anesthesia staff if sedation is used, and pathology review if biopsies are taken.
Many patients find sigmoidoscopy shorter than colonoscopy, but discomfort varies. Pressure, gas, and cramping may occur, and sedation options depend on the clinical plan.
Bowel movements may return the same day or within the next day, depending on your prep, diet, and bowel habits. Mild gas or loose stool can occur temporarily.
It can detect inflammation in the rectum and lower colon that may suggest Crohn’s disease or ulcerative colitis. A full diagnosis may require biopsies, colonoscopy, imaging, or lab tests.
