An endoscopy allows your doctor to see inside your digestive tract with remarkable clarity. This procedure uses a thin, flexible tube with a camera to examine your esophagus, stomach, and the beginning of your small intestine. But what exactly can be detected by an endoscopy?
The answer matters more than you might think. Many serious digestive conditions show few symptoms in their early stages. Detecting them during an upper endoscopy often means catching problems when they’re still manageable.
Conditions That Cause Inflammation and Irritation
Gastritis
Your digestive system’s lining can become inflamed for various reasons. Gastritis, an inflammation of the stomach lining, often develops from long-term use of pain medications or excessive alcohol consumption. During an endoscopy, your doctor can see the red, swollen tissue directly. This matters because untreated gastritis can lead to ulcers or, in rare cases, stomach cancer.
Ulcers
Speaking of ulcers, these painful sores in your stomach or upper small intestine show up clearly during an EGD (esophagogastroduodenoscopy). Ulcers aren’t just uncomfortable. They can bleed or create holes in your digestive tract if left untreated. An endoscopy lets your doctor assess the severity and start the right treatment immediately.
Celiac Disease
Celiac disease, an autoimmune condition triggered by gluten, damages the small intestine’s lining over time. During an endoscopy, your doctor can take tiny tissue samples (biopsies) to confirm the diagnosis. Early detection means you can adjust your diet before serious nutritional deficiencies develop.
Precancerous Changes and Cancer Detection
Barrett’s Esophagus
Barrett’s esophagus represents one of the most important findings during an endoscopy. This condition occurs when chronic acid reflux, or gastroesophageal reflux disease (GERD), damages the esophagus lining. The tissue changes to resemble intestinal tissue, a process called metaplasia.
Barrett’s esophagus increases your risk of esophageal cancer. Catching it early means your doctor can monitor these changes closely and intervene if precancerous cells appear. Regular surveillance can literally be lifesaving.
Cancers
Endoscopy excels at detecting cancers in their earliest stages. Esophageal cancer, stomach cancer, and certain types of small intestine cancer all become visible during this procedure. Early-stage cancer is dramatically more treatable than advanced disease. A small tumor caught during routine endoscopy might be removed completely, while that same cancer discovered months later could require chemotherapy and major surgery.
Polyps
Your doctor can also spot and remove polyps during an endoscopy. These small growths can develop into cancer over time, so removing them during the procedure eliminates that future risk entirely.
Structural Problems That Affect Digestion
Hernia
Sometimes the issue isn’t disease but anatomy. A hiatal hernia occurs when part of your stomach pushes through the diaphragm into your chest cavity. This can cause severe heartburn and chest pain that mimics a heart attack. Endoscopy reveals the hernia’s size and helps your doctor decide if surgery is necessary.
Esophageal Strictures
Esophageal strictures are narrowings of the esophagus that make swallowing difficult. They develop from chronic acid reflux, radiation treatment, or swallowing caustic substances. During an endoscopy, your doctor can dilate these strictures right then and there, providing immediate relief.
Varices
Varices, or enlarged veins in the esophagus, typically develop in people with liver disease. These swollen vessels can rupture and cause life-threatening bleeding. Detecting them before they bleed allows your doctor to take preventive measures.
Infections That Affect Your Upper GI Tract
Helicobacter pylori (H. pylori) is a bacterial infection that burrows into your stomach lining. It causes ulcers and increases stomach cancer risk significantly. During an endoscopy, your doctor can take a biopsy to test for this bacteria. A simple course of antibiotics can eliminate the infection completely.
Certain viral, bacterial, and fungal infections also appear during endoscopy, particularly in people with weakened immune systems. Identifying the specific infection guides targeted treatment.
