An endoscopy is a medical procedure that allows a doctor to view the inside of your digestive tract using a thin, flexible tube with a camera at the end (called an endoscope). It is commonly used to examine the esophagus, stomach, and the beginning of the small intestine (duodenum).
Why is an endoscopy performed?
- To investigate symptoms such as heartburn, nausea, vomiting, abdominal pain, difficulty swallowing, or bleeding
- To diagnose conditions such as gastritis, ulcers, reflux disease (GERD), or tumors
- To take biopsies (small tissue samples)
- To treat certain conditions (e.g., stop bleeding, remove polyps, or stretch narrowed areas)
What can an endoscopy detect?
- Gastritis or inflammation
- Ulcers
- Esophageal reflux or damage (GERD)
- Hiatal hernias
- Bleeding sources
- Tumors or early signs of cancer
- Celiac disease
- Narrowing or blockages
How should I prepare?
- Do not eat or drink for at least 6–8 hours before the procedure.
- Your doctor may ask you to stop certain medications temporarily.
- Arrange for someone to drive you home afterward.
How long does it take?
The procedure usually takes between 15 and 30 minutes. It is typically performed as an outpatient procedure.
What type of anesthesia is used?
Most patients receive light sedation through an IV to help them relax and avoid discomfort. You’ll be awake, but drowsy and likely won’t remember the procedure.
When can I go back to work?
Most people return to normal activities the next day. You may feel a bit bloated or have a sore throat for a few hours.
Your health matters. Don’t ignore digestive symptoms; early detection saves lives.
