What is a GI endoscopy?

A GI (gastrointestinal) endoscopy is a procedure Dr. Nazarian might need to perform if you have symptoms of a digestive system disorder. It can also be invaluable as a screening tool for identifying the first signs of serious conditions like colorectal cancer.

Your gastrointestinal system includes all the parts of your body involved with digesting food. It starts with your mouth, where you chew and mix food with saliva, and continues through your stomach, small intestine, and large intestine or bowel. Your gastrointestinal system ends with your rectum and anus, where you excrete waste matter left after digestion.

A GI endoscopy could involve an inspection of your stomach or your bowel and rectum. Dr. Nazarian can use it to diagnose symptoms like rectal bleeding, persistent diarrhea, acid reflux, or possible signs of cancer.

What are upper and lower GI endoscopy?

An upper GI endoscopy involves having a camera passed down your throat and into your stomach. The camera relays images of your esophagus, stomach lining, and the top section of your small intestine to a screen for Dr. Nazarian to analyze.

A lower GI endoscopy – more commonly known as a colonoscopy – is a procedure where the camera passes through your anus into your rectum and around the entire large intestine. Sometimes, it's only necessary to see the first part of the large intestine, in which case you might undergo a sigmoidoscopy instead.

What happens when I have a GI endoscopy?

Before your GI endoscopy, you need to completely empty your stomach or bowels. That means limiting food intake the day before your procedure, and for a colonoscopy, clearing your intestines by taking strong laxatives.

In both an upper GI endoscopy and a colonoscopy, you have a sedative to ensure you stay calm and relaxed. An endoscope is a flexible piece of tubing that's narrow enough to pass into your body without difficulty. Each procedure uses slightly different instruments.

During your GI endoscopy, Dr. Nazarian can not only see the tissues in detail; he can also take samples (biopsies) for laboratory analysis. He might also be able to address certain problems; for example, if you have polyps in your colon, he can remove them, and if there's bleeding in your stomach, he may be able to treat the cause.

If you have unexplained gastrointestinal symptoms, GI endoscopy could provide the diagnosis you need. To find out more or arrange a colorectal cancer screening, call the office of Jamshid Nazarian, MD, FACS, or request an appointment online today.
