OGD (Gastroscopy) in Nairobi: A Complete Guide to Upper Gastrointestinal Endoscopy

Expert Gastroscopy Services at Endoscopy Center Nairobi

Digestive symptoms such as persistent heartburn, upper abdominal pain, difficulty swallowing, nausea, vomiting, unexplained weight loss, or gastrointestinal bleeding should never be ignored. These symptoms may be caused by a variety of conditions affecting the oesophagus, stomach, or the first part of the small intestine (duodenum). One of the most accurate ways to investigate these conditions is through an Oesophagogastroduodenoscopy (OGD), commonly known as a gastroscopy or upper gastrointestinal (GI) endoscopy.

At Endoscopy Center Nairobi, we provide safe, accurate, and patient-centred gastroscopy services using modern Olympus endoscopy systems. Our experienced healthcare professionals are committed to diagnosing digestive disorders early, providing therapeutic endoscopic procedures when required, and ensuring every patient receives compassionate, high-quality care.

Whether your doctor has referred you or you are seeking answers to persistent digestive symptoms, this guide explains everything you need to know about gastroscopy, including why it is performed, how to prepare, what to expect, and how it can help protect your digestive health.

What Is an OGD (Gastroscopy)?

An Oesophagogastroduodenoscopy (OGD) is a minimally invasive medical procedure that allows a doctor to examine the lining of the upper digestive tract using a thin, flexible tube called an endoscope.

The endoscope contains a high-definition camera and a light source that transmit real-time images to a monitor, enabling the doctor to identify abnormalities that may not be visible on X-rays or scans.

During the procedure, the doctor carefully examines three important parts of the digestive system:

Oesophagus – the tube that carries food from the mouth to the stomach.
Stomach – where food is mixed with digestive juices.
Duodenum – the first section of the small intestine.

Unlike many imaging tests, gastroscopy/OGD not only allows doctors to diagnose disease but also to perform certain treatments during the same procedure. Tissue samples (biopsies) can be obtained painlessly for laboratory analysis; bleeding can be controlled; narrowed areas can be widened; and certain growths can be removed without the need for surgery.

Because of its accuracy and versatility, upper endoscopy is considered the gold standard for evaluating many upper gastrointestinal conditions.

Who Needs an Upper Endoscopy?

Your healthcare provider may recommend a gastroscopy if you experience symptoms that suggest a problem within the upper digestive tract.

Common reasons include:

Persistent upper abdominal pain
Frequent heartburn or acid reflux (GERD)
Difficulty swallowing (dysphagia)
Pain when swallowing
Persistent nausea or vomiting
Vomiting blood
Black or tarry stools
Unexplained weight loss
Persistent indigestion
Recurrent bloating after meals
Iron deficiency anaemia without an obvious cause
Chest discomfort thought to originate from the oesophagus
Persistent symptoms despite medication

Gastroscopy may also be recommended for individuals who:

Have a family history of stomach or oesophageal cancer
Require follow-up of Barrett's oesophagus
Need monitoring of gastric ulcers
Have previously undergone upper gastrointestinal surgery
Require surveillance for chronic digestive diseases

Early investigation often allows diseases to be detected before serious complications develop.

Why Is Gastroscopy Performed?

Gastroscopy is performed to diagnose, monitor, and sometimes treat conditions affecting the upper digestive tract.

Conditions commonly diagnosed include:

Gastro-oesophageal reflux disease (GERD)
Gastritis
Peptic ulcer disease
Helicobacter pylori (H. pylori) infection
Barrett's oesophagus
Coeliac disease
Oesophageal strictures
Oesophageal varices
Hiatal hernia
Gastric polyps
Duodenal ulcers
Upper gastrointestinal bleeding
Oesophageal cancer
Stomach cancer

Gastroscopy may also be performed to investigate abnormal findings seen on CT scans, MRI, ultrasound, or X-rays.

Benefits of Upper Endoscopy.

Upper Endoscopy provides numerous advantages for both patients and healthcare providers.

Benefits include:

Accurate diagnosis of digestive disorders
Early detection of stomach and oesophageal cancers
Ability to diagnose ulcers and inflammation
Collection of tissue samples without surgery
Simultaneous diagnosis and treatment
Short procedure time
Rapid recovery
Minimally invasive approach
Reduced need for exploratory surgery
Improved treatment planning
Better long-term patient outcomes

Early diagnosis significantly improves the chances of successful treatment, especially for cancers and bleeding disorders.

How to Prepare for Your Gastroscopy

Proper preparation is essential to obtain clear images of the digestive tract.

Before your procedure, you should:

Fasting

Do not eat or drink anything for at least 6–8 hours before your appointment unless instructed otherwise by your doctor.

Medications

Inform your healthcare provider about:

Blood-thinning medications
Diabetes medication
Blood pressure medication
Heart medication
Allergies
Previous reactions to sedation

Never stop prescribed medication without medical advice.

Medical Conditions

Inform your doctor if you have:

Heart disease
Lung disease
Diabetes
Pregnancy
Bleeding disorders
Previous upper GI surgery

Arrange Transportation

If sedation is planned, arrange for a responsible adult to accompany you home, as you should not drive or operate machinery afterwards.

What Happens During the Procedure?

Upon arrival, your medical history will be reviewed, and the procedure will be explained before you sign a consent form.

During the examination:

You will lie comfortably on your left side.
Your throat will be numbed using a local anaesthetic spray.
Sedation may be administered to help you relax.
A mouthguard will protect both your teeth and the endoscope.
The flexible endoscope is gently passed through the mouth into the oesophagus, stomach, and duodenum.
Air will be introduced to improve visibility.
The doctor carefully examines the digestive tract.
Biopsies or therapeutic procedures are performed if required.
The endoscope is gently removed.

The procedure typically takes 10–20 minutes, although therapeutic procedures may take longer.

Conditions That Can Be Treated During Gastroscopy

One of the major advantages of gastroscopy is that it is both a diagnostic and therapeutic procedure.

Depending on the findings, your doctor may:

Remove certain polyps
Obtain tissue biopsies
Stop active bleeding
Inject medication into bleeding ulcers
Apply clips to bleeding blood vessels
Dilate narrowed sections of the oesophagus
Remove swallowed foreign objects
Insert feeding tubes when medically necessary

These treatments often eliminate the need for open surgery.

Will a Biopsy Be Taken?

Many patients worry when they hear the word "biopsy."

A biopsy simply means that a tiny sample of tissue is taken for microscopic examination.

Biopsies are commonly performed to:

Diagnose H. pylori infection
Confirm gastritis
Detect coeliac disease
Evaluate Barrett's oesophagus
Investigate ulcers
Diagnose cancers
Rule out abnormal tissue changes

Biopsies are painless because the lining of the digestive tract does not contain pain receptors that detect tissue sampling.

Recovery After Gastroscopy

After the procedure, you will remain in the recovery area until you are fully awake if sedation was used.

Most patients experience only mild symptoms, including:

Temporary sore throat
Mild bloating
Passing gas
Mild drowsiness

These symptoms usually resolve within a few hours.

If sedation was administered:

Do not drive for 24 hours.
Avoid alcohol.
Avoid signing important legal documents.
Rest for the remainder of the day.

Most patients return to normal activities the following day.

Frequently Asked Questions
