A gastroenterologist is a medical specialist who focuses on the diagnosis and treatment of conditions and diseases affecting the digestive system. The digestive system includes organs such as the stomach, intestines, liver, pancreas, and gallbladder. Gastroenterologists are trained to diagnose and manage a wide range of digestive disorders, from common problems such as acid reflux and constipation to more complex conditions such as inflammatory bowel disease and liver cirrhosis.
These specialists use a variety of diagnostic tools and procedures, including endoscopy, colonoscopy, and imaging tests, to accurately identify and treat their patients’ digestive issues. Additionally, they work closely with other healthcare professionals, such as nutritionists and surgeons, to provide comprehensive care to their patients.

What is Gastroenterology?
Gastroenterologists are medical specialists who undergo extensive training to diagnose and treat a wide range of digestive disorders, from common conditions such as acid reflux and irritable bowel syndrome to more complex issues such as inflammatory bowel disease and liver cirrhosis.
What are the common symptoms of digestive disorders?
There are many symptoms that may indicate the presence of a digestive disorder. Some common symptoms of digestive disorders include:
- Abdominal pain or discomfort
- Bloating or gas
- Constipation or diarrhea
- Nausea or vomiting
- Heartburn or acid reflux
- Loss of appetite
- Difficulty swallowing
- Unexplained weight loss
- Bloody stools or rectal bleeding
- Fatigue or weakness
What conditions do gastroenterologists treat?
Gastroenterologists diagnose, treat, and manage a wide range of digestive disorders, including:
- Acid reflux (GERD)
- Peptic ulcer disease
- Irritable bowel syndrome (IBS)
- Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis
- Celiac disease and gluten intolerance
- Gallbladder and biliary tract disease
- Liver diseases, such as hepatitis, cirrhosis, and fatty liver disease
- Gastrointestinal (GI) cancers, including colon, rectal, and pancreatic cancer
- Diverticular disease
- Gastrointestinal infections, such as gastroenteritis and H. pylori infection
- GI bleeding
- Malabsorption syndromes
- Food intolerances and allergies
How do gastroenterologists diagnose digestive issues?
Gastroenterologists use a variety of tools and procedures to diagnose digestive issues. Some common methods for diagnosing digestive disorders include:
Medical history and physical exam
The gastroenterologist will typically start by asking about the patient’s symptoms, medical history, and any medications they are taking. They may also perform a physical exam to check for signs of digestive problems.
Blood tests can help to identify signs of infection, inflammation, and other underlying conditions that may be contributing to digestive problems.
Imaging tests such as X-rays, CT scans, MRIs, and ultrasounds can provide detailed images of the digestive tract, liver, and other organs to help identify structural abnormalities, blockages, or other issues.
Endoscopy involves inserting a thin, flexible tube with a camera and light at the end into the digestive tract to examine the lining of the esophagus, stomach, and small intestine. This procedure can help to diagnose conditions such as GERD, ulcers, and inflammation.
Colonoscopy is a procedure that involves inserting a long, flexible tube with a camera and light at the end into the colon to examine the lining and identify polyps, tumours, or other abnormalities that may indicate colon cancer or other conditions.
Stool tests can help to identify infections, inflammation, and other issues in the digestive tract, including tests for faecal occult blood, faecal calprotectin, and stool cultures.
Based on the results of these tests and procedures, the gastroenterologist can make a diagnosis and develop a treatment plan tailored to the patient’s specific condition and needs.
What is the difference between a gastroenterologist and a general practitioner?
A gastroenterologist is a medical specialist who focuses specifically on the diagnosis and treatment of conditions and diseases affecting the digestive system. They undergo extensive training in this area, typically completing a three-year internal medicine residency followed by a two- to three-year gastroenterology fellowship.
In contrast, a general practitioner (GP) is a primary care physician who provides comprehensive medical care to patients of all ages, with a focus on preventive care and the management of a wide range of health issues. GPs do not have the specialized training in gastroenterology that a gastroenterologist has, but they may refer patients with digestive issues to a gastroenterologist for further evaluation and treatment.
Gastroenterologists are often consulted when a patient has a complex or persistent digestive issue that requires specialized expertise or diagnostic testing that is not available in a general practice setting. They work closely with GPs and other healthcare professionals to provide comprehensive care to their patients and help manage digestive disorders effectively.
Q1: What should I expect during a colonoscopy?
Ans: During a colonoscopy, you will be sedated and a gastroenterologist will insert a long, flexible tube with a camera and light at the end into your rectum to examine your colon.
Q2: Can lifestyle changes help improve my digestive health?
Ans: Yes, lifestyle changes such as eating a healthy diet, staying hydrated, getting regular exercise, and managing stress can help improve digestive health.
Q3: What is inflammatory bowel disease (IBD)?
Ans: IBD is a chronic condition that causes inflammation and damage to the digestive tract, including Crohn’s disease and ulcerative colitis.
Q4: What is a gastroscopy?
Ans: A gastroscopy is a procedure that involves inserting a thin, flexible tube with a camera and light at the end into the oesophagus, stomach, and duodenum to examine the lining and diagnose digestive issues.
Q5: What is the difference between a gastroscopy and a colonoscopy?
Ans: A gastroscopy examines the upper digestive tract, while a colonoscopy examines the colon and rectum. Both procedures are used to diagnose digestive issues.
