Endoscopy: What You Need To Know

Endoscopy: What You Need To Know

When hearing about endoscopy, what comes to mind is gastroscopy or the procedure to check the digestive tract. But an endoscopy has different types and is used to check different parts of the body. Essentially, an endoscopy uses a tube with a camera at the end to check the condition of your organs. Is endoscopy painful? How do patients prepare for this kind of procedure? What happens during endoscopy? Learn more about it here.

What Is Endoscopy?

Endoscopy is a diagnostic procedure where an endoscope, or a tube with a camera at the end, is inserted into the body to check the different organs. The tube is fitted with its own light and is maneuvered through the tract to capture images. The video is received through a monitor and is checked by the doctor while it is moving inside.

There are different types of endoscopy:

  • Esophagogastroduodenoscopy (EGD), upper GI endoscopy or gastroscopy – This checks the esophagus, stomach, and small intestine
  • Colonoscopy – Colon and rectum
  • Anoscopy – Anus
  • Enteroscopy – Small intestine
  • Bronchoscopy – Airways and lungs
  • Laparoscopy – Ovaries and other abdominal organs
  • Hysteroscopy – Uterus
  • Cystoscopy – Bladder

When Is It Recommended To Get One?

Whether “Is endoscopy painful?” should not be a factor, especially if your doctor recommends the procedure to help diagnose your condition.

However, typically, endoscopy is recommended for patients for the following:

  • To get tissue samples or biopsies to check current conditions of the body
  • Check symptoms causing pain and bleeding
  • To treat illnesses and to remove foreign objects that cause the symptoms

How Do You Prepare For It?

Knowing the risks involved in endoscopy allows patients to prepare for the procedure. As this might involve anesthesia, some may have an allergic reaction to it. Consult your doctor regarding this matter. In addition, there might be possible bleeding and infections, which can be addressed with medication.

Before Endoscopy

Doctors provide briefings so that the patients will know what to expect during the procedure. Depending on the type of endoscopy, some are asked to fast for 8 hours prior to the procedure or to observe bowel preparations so that this does not interfere with the procedure. Sedatives are given to help the patients relax. Some are given local or general anesthetics.

During Endoscopy

Is endoscopy painful? No. Some might not even remember the procedure, as patients are usually put under using a strong sedative.

While the patient is unconscious, doctors insert the endoscope into the body carefully so that this will not create any injury. Air is passed inside the body to make it easier for the probe to move. The monitor helps to navigate the endoscope to see the problem area of the patient.

Some include simple procedures such as collecting samples or removing foreign objects during the endoscopy.

After Endoscopy

After the procedure, patients are brought to the recovery area until the anesthetic wears off. Some are advised to eat and drink after a few hours as the sedative may affect swallowing.

Often, patients are not allowed to drive during this time. It is advisable to ask your family or friends to take you home.

Some of the possible discomforts that patients may experience after endoscopy, especially if this is done via mouth are:

  • Bloating due to the gas used during endoscopy
  • Sore throat
  • Cramps

These discomforts are normal but if there are other conditions that you feel after the endoscopy, it is best to consult your doctor.

Key Takeaway

Endoscopy is just like any other diagnostic procedure, it helps patients and doctors to identify possible causes of illness and to gain more information about your particular condition.

There are different types of endoscopy, and they are recommended depending on which part of the body is to be examined. Is endoscopy painful? Not quite, but one may feel certain discomforts after undergoing the procedure. Consult your doctor about what to expect if you’re to undergo an endoscopy.
