OGDscopy
OGDscopy (Upper GI Endoscopy)
OGDscopy, also called Upper GI Endoscopy or Gastroscopy, is a procedure used to examine the inside of the food pipe (esophagus), stomach, and first part of the small intestine (duodenum) using a thin flexible tube with a camera called an endoscope.
It helps doctors diagnose and sometimes treat problems related to the upper digestive system.

1. Preparation
- Patient lies on the left side
- BP, pulse, and oxygen are monitored
2. Throat Spray / Sedation
- Local anesthetic throat spray may be used
- Mild sedation is often given for comfort
3. Endoscope Insertion
- A thin flexible camera tube is gently passed through the mouth
-
It goes into:
- Esophagus
- Stomach
- Duodenum
4. Examination
The doctor carefully examines:
- Ulcers
- Inflammation
- Bleeding
- Growths
- Infection signs
5. Biopsy or Treatment
If needed, the doctor may:
- Take biopsy
- Stop bleeding
- Remove small polyps
- Dilate narrowing
- Remove foreign body
6. Completion
- Scope is removed gently
- Entire procedure usually takes 5–15 minutes
Is OGDscopy Painful?
Usually, it is:
- Not painful
- Mildly uncomfortable without sedation
- Comfortable with sedation
Some patients may feel:
- Temporary gagging sensation
- Mild throat irritation
- Bloating after procedure
These usually settle quickly.
What Happens After the Procedure?
After recovery:
- Patient is observed for some time
- Mild throat discomfort may occur
- Eating is allowed once fully awake
- Sedation patients should avoid driving for 24 hours
Biopsy reports may take a few days.
Benefits of OGDscopy
- Early diagnosis of serious disease
- Detects ulcers and cancers early
- Helps identify bleeding source
- Can perform treatment immediately
- Accurate and minimally invasive
Risks and Complications
OGDscopy is generally very safe, but rare complications include:
- Bleeding
- Infection
- Perforation (small tear)
- Sedation-related breathing issues
These complications are uncommon when performed by experienced specialists.
Who Should Not Delay OGDscopy?
Patients with:
- Persistent reflux
- Difficulty swallowing
- Unexplained anemia
- Weight loss
- GI bleeding
- Recurrent vomiting
- Family history of GI cancers
should not delay evaluation.
