What is a colonoscopy?
A colonoscopy is a procedure designed to identify problems in the large intestine and the last portion of the small intestine (the ileum).
During the procedure, Dr. Vizuete inserts a colonoscope into your anus and guides it through the colon. A small camera on the end of the device allows Dr. Vizuete to see the internal structure of your digestive tract in real time and identify abnormalities.
Your comfort in our priority. At the endoscopy center, we have friendly nurses and technicians, and highly experienced anesthesia providers. Most patients choose to be sedated for their procedures, but let Dr. Vizuete know if you would like to remain awake. He takes pride in the quality and technique of this procedure and never wants you to worry about being in pain.
Dr. Vizuete is an expert in detecting adenomas, which are benign tumors that are often found lining the colon.
When should I get a colonoscopy?
You would speak to Dr. Vizuete about getting a colonoscopy if you experience any of the following symptoms:
- Unprovoked abdominal pain or cramping
- Rectal bleeding
- Loose stools lasting over a month
- A change in your bowel habit
- A family history of colon, stomach, uterine or endometrial, ovarian, pancreas, or bladder cancer
A colonoscopy can help Dr. Vizuete develop a comprehensive assessment of your symptoms and recommend treatment.
How do I prepare for a colonoscopy?
The most important thing to keep in mind while you prepare for your colonoscopy is that your colon must be cleaned before the procedure for the doctor to get accurate results.
During your preparatory appointment, Dr. Vizuete will recommend measures you can take at home to clean out your colon, such as decreasing your fiber intake for several days preceding your colonoscopy and avoiding all solid food 24 hours before the exam in addition to your prescribed bowel prep. Dr. Vizuete offers several different options for your bowel prep, so please inquire!
Will I need downtime after a colonoscopy?
In most cases, you should be able to resume your daily activities within a few hours of your colonoscopy and return to work the next day.
If Dr. Vizuete gives you a sedative to help you relax, you will need to wait for it to fully wear off before you can go home. This usually takes about half an hour. You should arrange for someone to drive you to and from your colonoscopy.
In the days following your colonoscopy, it’s possible that you’ll feel some cramping, but you should be able to go back to your usual diet immediately.
Please contact Dr. Vizuete if you were to experience pain, vomiting or fever after a colonoscopy
