What Is Gastroenterology?

Gastroenterology is a medical specialty that focuses on the diagnosis and treatment of diseases of the digestive system. This includes the esophagus, stomach, small and large intestines, liver, gallbladder, bile ducts, and pancreas. Conditions such as reflux disease, gastritis, ulcers, intestinal disorders, hepatitis, pancreatitis, and gallstones are diagnosed and treated by gastroenterology specialists.

What Diseases Does Gastroenterology Treat?

The gastroenterology department manages a wide range of digestive system disorders, including:

• Gastroesophageal reflux disease (GERD) and gastritis
• Gastric and duodenal ulcers
• Irritable Bowel Syndrome (IBS)
• Crohn’s disease and ulcerative colitis
• Colon polyps and colorectal cancer
• Liver diseases (hepatitis, fatty liver disease)
• Gallbladder and bile duct diseases
• Pancreatitis and pancreatic disorders

When Should You See a Gastroenterologist?

The following symptoms may require evaluation by a gastroenterology specialist:

• Heartburn and indigestion
• Abdominal pain and bloating
• Chronic diarrhea or constipation
• Difficulty swallowing
• Blood in stool or vomit
• Unexplained weight loss
• Jaundice (yellowing of the skin and eyes)

If these symptoms persist, early specialist assessment is essential for timely diagnosis and treatment.

Diagnostic Methods Used in Gastroenterology

Modern and reliable diagnostic techniques are used to evaluate digestive system diseases:

• Endoscopy
• Colonoscopy
• ERCP (Endoscopic Retrograde Cholangiopancreatography)
• Enteroscopy
• Sigmoidoscopy
• Esophageal manometry

These methods allow early detection of diseases and help create an appropriate treatment plan.
