Before it

Endoscopy is usually done in the hospital itself. There may be some types of endoscopy that require more preparation before starting the procedure.

For example, depending on the part of the body to be tested, the patient may need to abstain from eating and drinking before the endoscopy.

The doctor also advises the patient about how long before the procedure begins to abstain from food and whether the patient can consume liquids or abstain from them.

If a colonoscopy test is to be done in the large intestine, the doctor may give the patient a laxative (laxative pill) before the procedure, which clears the stool from the intestines.

If patients are already taking any type of medication, they may have to stop taking the drug or change the time of the medication for a limited period of time before the procedure begins.

However, the medicines should not be stopped without consulting the doctor and unless the doctor tells them to stop them. Some people also need to take antibiotics before the endoscopy procedure.

During this

This procedure does not require an overnight stay in the hospital, as the procedure takes only up to 1 hour to complete.

The endoscopy procedure is usually not painful, some people may experience mild discomfort during it (a sore throat or sore throat).

Endoscopy is usually done in the conscious state of the patient. A local anesthetic is given to numb a specific area. This is usually in the form of a spray or lozenge to numb the throat.

Sedatives may be given to make the patient feel relaxed so that the patient is less aware of what is happening around him.

The endoscope is very carefully inserted into the patient’s body, the endoscope is sent exactly where the test is to be performed.

For example, it can be put in the following parts of the body –

  • Neck
  • Anus – The stool from the anus is first expelled from the body.
  • Urethra – First urine is removed from the body.
