Facing an endoscopy can raise a lot of questions. Is it painful? Will I be asleep? What can it find? In this friendly guide from Gastrodoxs.com, Dr. Bharat Pothuri answers all your concerns in simple words. Whether you live in the Texas Medical Center area or anywhere in Houston, we’ve got you covered.
An endoscopy is a simple test doctors use to look inside your body. It involves a thin, flexible tube called an endoscope. The endoscope has:
“It allows us to see the lining of your digestive tract up close,” says Dr. Bharat Pothuri. “We can spot inflammation, ulcers, or growths without making a big cut.”
Your doctor may order an endoscopy if you have symptoms like:
Endoscopy helps pinpoint the cause. It’s more accurate than X-rays for many conditions. The American Gastroenterological Association notes it’s the gold standard for looking at your esophagus, stomach, and part of your small intestine.
There are different endoscopies depending on where the camera goes:
Each type uses a similar scope but targets a different area.
Good prep makes your endoscopy smoother and safer. Here’s what most Houston GI centers will ask you to do:
A top question: “Is it painful to have an endoscopy?” Most patients say they feel pressure or mild discomfort, not real pain. The secret is good sedation and your relaxed throat or gut.
Dr. Pothuri explains, “With our approach in Houston’s Texas Medical Center, we use numbing sprays and conscious sedation. You’ll remember almost nothing.”
If you still feel uneasy, talk with your gastroenterologist about extra local anesthesia.
“Do they fully put you to sleep for an endoscopy?” It depends on your health and the office:
In Houston’s top GI clinics, moderate sedation is standard. You stay in control of reflexes but won’t feel discomfort.
“How long does an endoscopy take from start to finish?” Pipe up your watch:
Total time in the suite is about 1–2 hours. Block off half a day for parking, check-in, and post-procedure rest.
“What diseases can be detected by an endoscopy?” A lot! Here are common findings:
“Endoscopy is not just diagnostic,” adds Dr. Bharat Pothuri, “It’s therapeutic. We can remove polyps, stop bleeding vessels, or dilate strictures on the spot.”
A popular worry: “Is endoscopy a major procedure?” Generally, no. It’s considered minimally invasive. Here’s why:
However, any procedure has risks. If you need general anesthesia or an ERCP, make sure you understand potential complications.
While serious issues are rare, you should know endoscopy side effects:
If you notice severe belly pain, fever, or heavy bleeding, call your GI team or go to your nearest ER right away.
| Sedation Type | Conscious Sedation | Deep Sedation / GA |
| Patient Status | Drowsy, can follow simple commands | Asleep, no awareness |
| Airway Management | Patient breathes on own | May need breathing tube |
| Recovery Time | 30–60 minutes | 60–120 minutes |
| Typical Use | Routine EGDs & colonoscopies | Complex ERCPs, anxious pts |
If you’re in Houston or surrounding Harris County, keep these in mind:
An endoscopy is a safe, effective way to look inside your digestive tract. With modern sedation methods, most people feel little to no pain. It only takes a couple of hours from start to finish, and it can detect or treat many diseases early.
Dr. Bharat Pothuri sums it up: “We aim to make your endoscopy as smooth as possible. Early detection can save lives, especially here in Houston where rates of GI cancers remain high.”
