When Is Endoscopy Needed? Signs You Should Not Ignore

Endoscopy is one of the most powerful diagnostic tools in gastroenterology. It allows your doctor to directly look inside the esophagus, stomach, and small intestine using a thin, flexible camera — giving far more accurate information than an X-ray or ultrasound alone.

When should you consider an endoscopy?

If you experience any of the following symptoms persistently, an endoscopy may be recommended:

• ✓Chronic heartburn or acid reflux that doesn't respond to medication
• ✓Difficulty swallowing (dysphagia) — food feeling stuck
• ✓Unexplained weight loss — could indicate something serious
• ✓Blood in vomit or stools — always needs urgent evaluation
• ✓Persistent abdominal pain that doesn't resolve
• ✓Chronic nausea or vomiting

What happens during an endoscopy?

You will be given light sedation to ensure comfort. A flexible endoscope is gently passed through your mouth into your stomach. The entire procedure takes 10–20 minutes. Dr. Madan Karthik Raj will explain findings immediately after.

Is endoscopy painful?

No. With modern sedation, most patients don't remember the procedure at all. You may feel mild bloating afterward, which resolves within an hour.

Don't delay if symptoms persist. Early diagnosis through endoscopy can catch conditions like peptic ulcers, Barrett's esophagus, and early gastric cancer — when they are most treatable.
