Upper Endoscopy

An upper endoscopy, also known as an esophagogastroduodenoscopy (EGD), is a procedure that allows a doctor to look at the inside of your upper digestive tract. The procedure is performed by a doctor who specializes in diseases of the digestive system, called a gastroenterologist.

What is the procedure like?

During an upper endoscopy, you will be sedated by an anesthesia provider. The doctor will insert a long, flexible tube with a camera on the end into your mouth. The tube will be passed down your throat and into your stomach and small intestine. The doctor will use the camera to look for any abnormalities in your digestive tract.

Why do I need an upper endoscopy?

An upper endoscopy may be recommended if you have any of the following symptoms:

  • Difficulty swallowing
  • Heartburn
  • Nausea and vomiting
  • Abdominal pain
  • Blood in your stool
  • Unexplained weight loss

An upper endoscopy can also be used to diagnose and treat a variety of conditions, including:

  • Gastroesophageal reflux disease (GERD)
  • Peptic ulcers
  • Esophageal cancer
  • Barrett's esophagus
  • Stomach cancer
  • Small intestine cancer

What are the risks of an upper endoscopy?

The risks of an upper endoscopy are generally low. However, there is a small risk of complications, such as:

  • Bleeding
  • Perforation of the digestive tract

What should I do to prepare for an upper endoscopy?

You will need to follow your doctor's instructions on how to prepare for an upper endoscopy. Please do not eat or drink after midnight prior to your procedure.

What happens after an upper endoscopy?

After an upper endoscopy, you will be taken to a recovery area to rest. You may feel some soreness in your throat and stomach. You should be able to go home the same day.

What should I do after an upper endoscopy?

Your doctor will give you specific instructions on what to do after an upper endoscopy. You may be advised to avoid strenuous activity for a few days. You should also notify your doctor if you experience any of the following symptoms after the procedure:

  • Fever
  • Sore throat
  • Difficulty swallowing
  • Bleeding from your mouth, nose, or rectum
  • Abdominal pain

A colonoscopy is a medical procedure that allows doctors to examine the inner lining of the large intestine (colon) using a flexible, lighted tube called a colonoscope. This test is typically done as a screening test for colorectal cancer, which is the third most common type of cancer in both men and women.

Before the procedure, you will need to follow a special diet and take laxatives to clear your bowel. This is important because any fecal matter in your colon can interfere with the doctor's ability to see the lining of your colon clearly. You will also be asked to avoid solid food for at least 24 hours before the procedure.

During the colonoscopy, you will be given sedatives to help you relax and reduce discomfort. The doctor will insert the colonoscope through your anus and slowly guide it through your rectum and into your colon. Air will be pumped into your colon to expand it and allow for better visualization. The doctor will carefully examine the lining of your colon and may take tissue samples or remove any abnormal growths (polyps) for further examination.

The procedure usually takes about 30 minutes to an hour, and you may feel some mild cramping or discomfort. Afterward, you will be monitored until the sedatives wear off and the doctor has determined that you are safe to leave.

It is normal to experience some mild side effects after the procedure, such as bloating, gas, and mild abdominal discomfort. These symptoms typically resolve within a few hours. If you experience any severe or persistent symptoms, such as severe abdominal pain, fever, or rectal bleeding, you should contact your doctor immediately.

Overall, getting a colonoscopy can be an important step in maintaining your health and preventing colorectal cancer. It is generally a safe and well-tolerated procedure, but it is important to follow all preparation instructions and discuss any concerns with your doctor before the procedure.
