Colonoscopy Prep ,
Doctor Discussing Test Results with Patient on the Phone

A colonoscopy is an exam that allows your doctor to see the inside of your large intestine (colon) and rectum. This exam is one of the most effective methods for doctors to find the source of unusual gastrointestinal symptoms, look for colon polyps, and detect colon cancer. Most people are encouraged to have a colonoscopy by age 50 as a preventative measure, and once every 5-10 years following.

While the exam itself is brief, and most patients are under general anesthesia during it, it is still a procedure that many people dread. Of course, patients do not see or feel anything during the procedure itself – it is the preparation for a colonoscopy that is quite unpleasant.

Colonoscopy prep is crucial because the colon needs to be empty and clear of waste. For this to occur, you will need to stay close to a bathroom for several hours the day prior to your procedure. To prepare for your colonoscopy prep, here’s what you need to know:

  • You must take some kind of laxative to empty your bowels completely. Most of the time, you will be told to mix an over-the-counter (OTC) laxative product into a certain amount of liquid and consume it within a few hours.
  • You will probably want very soft toilet paper or moist wipes. After several trips to the bathroom, scratchy toilet paper may become too harsh.
  • Vaseline or diaper cream can be applied to your rectum to prevent skin irritation from diarrhea and frequent wiping.
  • You will only be allowed to consume a liquid diet the entire day before your colonoscopy. You can drink any clear liquids to help you stay hydrated while you are “emptying out”.
  • You must avoid all red-colored beverages. Red dye stains your intestines, making it difficult for your doctor to get a clear view of your large intestine. You can mix a laxative in with sports drinks, but avoid red-colored options.
  • Set up shop in the bathroom. Once you get a few doses into your laxative, you will be in the bathroom more than you will be out of it. Bring a book, TV, laptop, tablet, or other devices that can help you pass the time.

Colonoscopy prep is inconvenient and unpleasant, there’s just no way around it. However, once your procedure is complete, you will be able to get back to a normal diet and bathroom routine. If your colonoscopy is successful, you have 10 years to enjoy before the next one!

Nicole R.

Scheduling was extremely easy with Dr. Yamini's staff, I scheduled my Tuesday appointment on Monday afternoon. The staff and Dr. Yamini were courteous and straightforward - even with new patient paperwork I was out the door within an hour!

Bill C.

Dr. Yamini definitely is a great doctor who is very thorough and detail oriented with his diagnosis. He is very passionate about what he does and was able to answer any question or concern. He took his time before my appointment to look through all the documentation to know exactly what was going on. He definitely was able to put me at ease even though I was very worried. I am very satisfied with his services. Thanks!

Mario O.

He was very gentle about my situation yet did not fail to emphasize about the seriousness that could arise from gastrointestinal problems. Few and far between are as professional and caring as Dr. Yamini and his staff. I was 20 minutes late on Friday evening & they still had me in a room in 5 minutes as a new patient.

Lisa P.

I can’t say enough great things about my first impression of this doctor and his amazing staff! They got me right in and set me up for everything needed. I’ve been looking for the right GI doctor for years having had a very negative experience with another doctor years ago. Dr. Yamini is not only professional, knowledgeable, respectful, and experienced... this guy is “cool” and nice too! His front desk person, Toni was amazing! She was kind, bright, efficient, patient, and positive! ??

Makes talking about uncomfortable subjects a breeze. Competent and honest: doesn't sell vitamin cleanses and his own probiotics or anything like that. Makes sure your symptoms aren't half-fixed but fully fixed. Gets to the heart of the issue quickly. Good listener. Very sweet receptionist. I hate receiving many phone calls, and she's persistent about making sure you set up an appointment; it was stressing me out. I found the her much easier to connect with once she gave me her cell and said to text.

Babak E.

Thank you Dr. Yamini and Tony. When it comes to patient care and professionalism, I have never received this much care and attention from a physician and the staff. I was able to talk to Dr. Yamini for good period of time allowing me to ask all my questions. Tony you are so cute thank you for scheduling me in last minute.

Kyle K.

I highly recommend Dr. Yamini. He's very personable and actually listens to your issues and concerns, then recommends a reasonable course of action. He was able to properly diagnose my symptoms and get me healthy again. Also his admin Toni is great too, she will help select a facility and verify that your insurance will fully cover. She's really nice and trustworthy as well!

Eric W.

Thorough doctor who cares about his patients, and very meticulous about the details of your ailment. Clearly very knowledgeable and skilled. No wait time for appointments, and the nurse (Toni) is very friendly and follows up appropriately. One of the best doctor experiences I've had and I'd recommend it to anyone.
