What Can I Eat 2 Days Before a Colonoscopy? While a good colonoscopy prep rarely tops people's lists of fun things to do, it's an essential part of having a colonoscopy. During a colonoscopy, your doctor inserts a lighted scope into the rectum and advances it through the large and small intestine, looking for polyps, small fleshy growths that can turn cancerous. Restricting certain foods before a colonoscopy leaves less waste in the intestine to be removed during the prep. Realizing the importance of diet and prep before a colonoscopy may make your limited diet options beforehand more palatable. A colonoscopy allows your doctor to visualize the entire intestinal tract, but a colonoscopy is only as good as the prep. If your prep doesn't really .

A good prep allows easy visualization of the intestinal lining so polyps can be visualized and removed immediately. If polyps are found early, there's less likelihood that they will turn cancerous. It takes approximately 1. Anne Charette of Tufts University reports on Upto. Date. Colonoscopy requires several days of prep and the use of sedation. Doing the prep correctly the first time decreases the possibility of a repeat performance because of poor visualization. If an abnormal area needs to be better evaluated, a biopsy forceps can be passed through a channel in the colonoscope and a biopsy (a sample of the tissue) can be. During a colonoscopy, your. Upper endoscopy. ENDOSCOPY OVERVIEWAn upper endoscopy, often referred to as endoscopy, EGD, or esophago- gastro- duodenoscopy, is a procedure that allows a physician to directly examine the upper part of the gastrointestinal (GI) tract, which includes the esophagus, the stomach, and the duodenum (the first section of the small intestine) (figure 1). The physician who performs the procedure, known as an endoscopist, has special training in using an endoscope to examine the upper GI system, looking for inflammation (redness, irritation), bleeding, ulcers, or tumors. REASONS FOR UPPER ENDOSCOPYThe most common reasons for upper endoscopy include. Bleeding can be treated during the endoscopy. This may be caused by a narrowing (stricture) or tumor or because the esophagus is not contracting properly. If there is a stricture, it can often be dilated with special balloons or dilation tubes during the endoscopy. These instructions are designed to maximize your safety during and after the examination and to minimize possible complications. It is important to read the instructions ahead of time and follow them carefully. Do not hesitate to call the physician's office or the endoscopy facility if there are questions. You may be asked not to eat or drink anything for up to eight hours before the test. It is important for your stomach to be empty to allow the endoscopist to visualize the entire area and to decrease the possibility of food or fluid being vomited into the lungs while under sedation (called aspiration). You may be asked to adjust the dose of your medications (such as insulin) or to stop specific medications (such as blood thinning medications) temporarily before the examination. You should discuss your medications with your physician before your appointment for the endoscopy. You should arrange for a friend or family member to escort you home after the examination. Your doctor may perform the procedure to diagnose and. Photo Credit AndreyPopov/iStock/Getty Images. What Are The Risks Of A Colonoscopy? Risks Of A Colonoscopy Include Perforation, Bleeding, and Infection. Although you will be awake by the time you are discharged, the medications used for sedation may cause temporary changes in the reflexes and judgment and interfere with your ability to drive or make decisions (similar to the effects of alcohol). Patients who receive sedation are often required to be accompanied home after the procedure. WHAT TO EXPECT DURING ENDOSCOPYPrior to the endoscopy, the staff will review your medical and surgical history, including current medications. A physician will explain the procedure and ask you to sign consent. Before signing consent, you should understand the benefits and risks of the procedure, alternatives to the procedure, and all of your questions should be answered. If you are going to receive sedation for the procedure, an intravenous line (a needle inserted into a vein in the hand or arm) will be inserted to deliver medications. You may be given a combination of a sedative (to help you relax) and a narcotic (to prevent discomfort), or other medications that are commonly used for sedation. Your vital signs (blood pressure, heart rate, and blood oxygen level) will be monitored before, during, and after the examination. The monitoring is not painful. Oxygen is often given during the procedure through a small tube that sits under the nose and is fitted around the ears. For safety reasons, dentures should be removed before the procedure. Although most patients are sedated for the examination, many tolerate the procedure well without any medication. Usually, these patients are given a medication to numb the back of their throats (either a gargle or a spray) just prior to the endoscopy to prevent gagging during the passage of the instrument. This may be offered to patients felt to be at higher risk for receiving sedation. Otherwise, if you are interested in having your endoscopy in this sedation- free manner, you should discuss this with the doctor beforehand to see if this is a possibility for you. THE ENDOSCOPY PROCEDUREThe procedure typically takes between 1. The endoscopy is performed while you lie on your left side. A plastic mouth guard is placed between the teeth to prevent damage to the teeth and endoscope. The endoscope (also called a gastroscope) is a flexible tube that is about the size of a finger. The endoscope has a lens and a light source that allows the endoscopist to see the inner lining of the upper gastrointestinal (GI) tract, usually on a TV monitor. Most people have no difficulty swallowing the flexible gastroscope as a result of the sedating medications. Many people sleep during the test; others are very relaxed and generally not aware of the examination. An alternative procedure called transnasal endoscopy may be available in some facilities. This involves passing a very thin scope (about the size of a drinking straw) through the nose. You are not sedated but a medication is applied to the nose to prevent discomfort. A full examination can be performed with this instrument. The endoscopist may take tissue samples called biopsies. Obtaining biopsies is not painful. The endoscopist may also perform specific treatments (such as dilation, removal of polyps, treatment of bleeding), depending upon what is found during the examination. Air or carbon dioxide gas is gently introduced through the endoscope to open the esophagus, stomach, and intestine, allowing the endoscope to be passed through these areas and improving the endoscopist's ability to see completely. You may experience mild discomfort as air is pushed into the stomach and intestinal tract. This is not harmful; belching may relieve the sensation. The endoscope does not interfere with breathing. Taking slow, deep breaths just before and during the procedure may help you to relax. RECOVERY FROM ENDOSCOPYAfter the endoscopy, you will be observed for a period of time, generally less than one hour, while the sedative medication wears off. Some of the medicines commonly used cause some people to temporarily feel tired or have difficulty concentrating. You typically will be instructed not to drive and not to return to work for the balance of the day of the procedure. The most common discomfort after the examination is a feeling of bloating as a result of the air introduced during the examination. This usually resolves quickly. Some patients also have a mild sore throat. Most patients are able to eat shortly after the examination. ENDOSCOPY COMPLICATIONSUpper endoscopy is a safe procedure and complications are rare . The following is a list of some possible complications. Providing this information to the team ensures a safer examination. If redness, swelling, or discomfort occurs, you should call your endoscopist or primary care provider, or the number given to you at discharge. This is a serious complication but fortunately occurs extremely rarely. The following signs and symptoms should be reported immediately. Some fatigue is common after the examination, and you should plan to take it easy and relax the rest of the day. The endoscopist can describe the result of the examination before you leave the endoscopy facility. If biopsies have been taken or polyps removed, you should call for results at a time specified by the endoscopist, typically within one week.
