Preparing for Endoscopy: What Patients Should Know & How to Get Ready

 Whether you're experiencing persistent digestive discomfort or your doctor has recommended it for diagnosis, an endoscopy can be a valuable tool in identifying and treating a wide range of gastrointestinal issues.

At Vamsi Gastro & Liver Care, we understand that hearing the word "endoscopy" might make some patients nervous. But with the right preparation and guidance from an expert like Dr. Venkateswara Raju, widely known as the best gastro doctor in Bhimavaram, your procedure can be simple, smooth, and stress-free.

In this article, we’ll walk you through everything you need to know about getting ready for an endoscopy—so you feel informed, confident, and prepared.

📍 What Is an Endoscopy?

An endoscopy is a common outpatient procedure that allows your doctor to look inside your digestive tract using a thin, flexible tube with a small camera attached at the end (called an endoscope).

Depending on the area being examined, there are different types of endoscopy:

Upper GI endoscopy (esophagogastroduodenoscopy) – for examining the esophagus, stomach, and upper part of the small intestine

Colonoscopy – for checking the colon and rectum

Sigmoidoscopy – focuses on the rectum and lower part of the colon

Dr. Venkateswara Raju, the best gastro specialist in Bhimavaram, uses endoscopy to investigate symptoms like heartburn, difficulty swallowing, abdominal pain, chronic acidity, or unexplained weight loss. It can also detect ulcers, infections, inflammation, and cancers in early stages.

👨‍⚕️ Why You Might Need an Endoscopy

You may be advised to undergo an endoscopy if you experience:

Persistent indigestion or bloating

Frequent heartburn or acid reflux

Trouble swallowing (dysphagia)

Gastrointestinal bleeding (like black or bloody stools)

Chronic constipation or unexplained diarrhea

Suspected ulcers or tumors

Monitoring of existing gastrointestinal conditions like ulcers or Crohn’s disease

Getting an accurate diagnosis through endoscopy helps doctors provide targeted treatment, rather than just prescribing symptom-relief medications.

✅ How to Prepare for an Endoscopy

Proper preparation is crucial to ensure a clear view during the procedure and avoid any complications. Here's a step-by-step guide on how to get ready:

1. Follow Your Doctor’s Instructions

Before anything else, listen carefully to the specific preparation instructions given by your gastroenterologist. If you're seeing Dr. Venkateswara Raju, you can expect personalized guidance based on your type of endoscopy.

2. Fasting

For an upper GI endoscopy, you must not eat or drink for at least 6–8 hours before the procedure. This prevents food or liquid in your stomach from blocking the camera or causing aspiration (vomiting during sedation).

For a colonoscopy or lower GI procedure, your doctor will recommend a clear liquid diet the day before, and nothing by mouth a few hours prior.

Tip: Avoid dairy products, colored liquids (especially red or purple), alcohol, or carbonated drinks.

3. Bowel Preparation (If You’re Having a Colonoscopy)

If your procedure involves the lower digestive tract, your doctor will guide you through a bowel cleansing process, typically using a laxative solution the night before. This is crucial to clear your colon so the scope has a clean path to view internal tissues.

Make sure you stay close to a restroom during the cleansing process.

4. Inform About Medications

Tell your doctor in advance about any medications you're taking—especially blood thinners, diabetes medicines, insulin, and heart medications. Some may need to be paused or adjusted before the procedure.

If you have chronic conditions like high blood pressure, diabetes, or heart disease, Dr. Venkateswara Raju, the best gastro doctor in Bhimavaram, will review your medical history thoroughly before proceeding.

5. Arrange Transportation

Since most endoscopies are done under mild sedation, you may feel drowsy afterward. Arrange for someone to accompany you or drive you home after the procedure.

💉 What to Expect During the Procedure

Endoscopy is usually done on an outpatient basis and takes around 15–30 minutes, depending on the type.

Here’s how the procedure typically goes:

You'll be asked to lie down comfortably on your side.

A sedative will be given through an IV to help you relax. In some cases, only a local anesthetic (throat spray) may be used.

The doctor gently inserts the endoscope either through your mouth or the anal passage, depending on the type of endoscopy.

The camera transmits images to a screen, allowing the doctor to examine your digestive tract.

Small tissue samples (biopsies) may be taken if needed—this is painless.

After completion, you’ll be monitored for a short time in a recovery room.

⏳ Aftercare and Recovery

Most patients recover from the sedation within 30–60 minutes. Here’s what you should know for a smooth recovery:

You may experience mild bloating, gas, or a sore throat (if done through the mouth). These usually resolve within a few hours.

Avoid driving or operating machinery on the day of the test.

Start with light meals after 2–3 hours unless advised otherwise.

If any biopsies were taken, your doctor will let you know when to expect the results.

Watch for any warning signs like severe pain, vomiting, fever, or bleeding—and report them to your doctor immediately.
