What Is Endoscopy?

Endoscopy is a medical procedure in which a flexible tube with a small camera and light, called an endoscope, is gently passed through the mouth to examine the food pipe (esophagus), stomach, and the first part of the small intestine (duodenum).

The camera provides detailed images that help the gastroenterologist identify inflammation, ulcers, bleeding, infections, growths, and other abnormalities inside the digestive tract.

Endoscopy is commonly used when patients experience persistent digestive symptoms or when further evaluation is required.

Why Is Endoscopy Recommended?

A gastroenterologist may recommend an endoscopy to investigate symptoms such as:

• Persistent acidity or heartburn
• Chronic indigestion
• Difficulty swallowing
• Persistent nausea or vomiting
• Upper abdominal pain
• Unexplained gastrointestinal bleeding
• Black or tarry stools
• Vomiting blood
• Unexplained weight loss
• Persistent anemia
• Suspected stomach or esophageal ulcers

Endoscopy allows doctors to directly examine the digestive tract and, when required, collect tissue samples for further testing.

Diagnostic Endoscopy

Diagnostic endoscopy is primarily performed to identify the cause of digestive symptoms and detect abnormalities at an early stage.

During the procedure, the doctor may evaluate conditions such as:

Gastritis

Inflammation of the stomach lining may cause pain, nausea, bloating, and indigestion. Endoscopy helps assess the severity and possible cause of gastritis.

Peptic Ulcers

Ulcers in the stomach or duodenum can cause abdominal pain and, in some cases, gastrointestinal bleeding. Endoscopy can help identify ulcers and assess their condition.

Gastroesophageal Reflux Disease (GERD)

Persistent acid reflux can affect the esophagus. Endoscopy may be recommended for selected patients to evaluate complications related to long-term reflux.

Difficulty Swallowing

Patients with persistent difficulty swallowing may require endoscopic examination to identify narrowing, inflammation, or other abnormalities in the food pipe.

Gastrointestinal Bleeding

Endoscopy plays an important role in identifying the source of bleeding in the upper digestive tract.

Therapeutic Endoscopy: Treatment Without Major Surgery

One of the major advantages of modern endoscopy is that it can sometimes be used not only for diagnosis but also for treatment.

Therapeutic endoscopy involves specialized procedures performed through an endoscope to manage certain gastrointestinal conditions without the need for major open surgery.

Depending on the patient’s condition, therapeutic endoscopy may be used for:

• Controlling gastrointestinal bleeding
• Removing certain polyps or abnormal tissue
• Treating selected narrowing or strictures
• Managing certain foreign bodies
• Performing other specialized gastrointestinal interventions

The exact treatment depends on the patient’s diagnosis, medical condition, and clinical evaluation.

Endoscopy for GI Bleeding

Gastrointestinal bleeding can be a serious medical condition and may require urgent evaluation.

Symptoms may include:

• Vomiting blood
• Black or tarry stools
• Weakness or dizziness
• Sudden drop in hemoglobin

Endoscopy can help identify the source of bleeding and, in appropriate cases, allow the gastroenterologist to perform treatment during the same procedure.

Patients experiencing vomiting of blood, black stools, fainting, or severe weakness should seek urgent medical attention.

Is Endoscopy Safe?

Endoscopy is a commonly performed medical procedure and is generally considered safe when performed for appropriate indications by trained medical professionals. However, like any medical procedure, it may involve certain risks.

The doctor will evaluate the patient’s health condition and explain the procedure, preparation, benefits, and possible risks before endoscopy.

How Should You Prepare for an Endoscopy?

Preparation may vary depending on the type of endoscopic procedure. For upper gastrointestinal endoscopy, patients are commonly advised not to eat or drink for a specified period before the procedure.

It is important to inform the doctor about:

• Current medications
• Blood-thinning medicines
• Diabetes medicines
• Allergies
• Previous surgeries
• Existing medical conditions

Patients should always follow the specific instructions provided by their gastroenterologist.
