Gastro Sciences

Gastro Sciences and Gastroenterology Care

Gastro Sciences is a medical specialty focused on the diagnosis, treatment and ongoing management of conditions affecting the digestive system. It covers the oesophagus, stomach, small intestine, colon, rectum, liver, pancreas, gallbladder and bile ducts. Gastroenterology care may involve medical treatment, diagnostic testing, therapeutic endoscopy and, when required, referral for surgical management.

Digestive problems can range from common concerns such as acidity, indigestion and constipation to more complex conditions involving the liver, pancreas, biliary system or intestines. A gastroenterologist evaluates symptoms, medical history and test results to identify the underlying cause and recommend an appropriate treatment plan.

Conditions Treated in Gastro Sciences

The specialty provides evaluation and management for a broad range of gastrointestinal and digestive disorders, including:

Stomach and Upper Digestive Disorders

Common upper gastrointestinal conditions include:

• Acid reflux and GERD
• Gastritis
• Peptic ulcers
• Indigestion and persistent abdominal discomfort
• H. pylori-associated digestive problems
• Oesophageal disorders
• Gastrointestinal bleeding

Persistent heartburn, difficulty swallowing, recurrent vomiting, unexplained stomach pain or changes in digestion may require assessment by a gastroenterologist rather than relying only on self-medication.

Intestinal and Colon Disorders

Gastroenterology also covers diseases affecting the small and large intestine, including:

• Irritable Bowel Syndrome (IBS)
• Crohn's disease
• Ulcerative colitis
• Inflammatory bowel disease (IBD)
• Chronic constipation or diarrhoea
• Intestinal infections
• Colon polyps
• Diverticular disorders
• Colorectal conditions

The evaluation may include blood or stool tests, imaging, colonoscopy or other investigations depending on the symptoms and clinical history.

Liver and Hepatology Care

The liver and biliary system are closely connected to digestive health. Gastroenterology services may include assessment and management of:

• Fatty liver disease
• Hepatitis
• Liver inflammation
• Liver fibrosis and cirrhosis
• Jaundice
• Portal hypertension
• Abnormal liver function tests
• Other chronic liver disorders

Early evaluation can help identify liver problems and determine whether monitoring, lifestyle changes, medication or specialist management is appropriate.

Pancreas and Gallbladder Disorders

Gastro Sciences also addresses conditions involving the pancreas, gallbladder and bile ducts, such as:

• Pancreatitis
• Gallstones
• Gallbladder inflammation
• Bile duct disorders
• Pancreatic cysts and other pancreatic conditions
• Biliary obstruction

Depending on the condition, doctors may recommend laboratory testing, ultrasound, CT, MRI/MRCP, endoscopic procedures or other investigations.

Gastroenterology Tests and Procedures

Accurate diagnosis is an important part of digestive disease management. Depending on the patient's symptoms and suspected condition, a gastroenterologist may recommend diagnostic or therapeutic procedures.

Upper GI Endoscopy

Upper GI endoscopy uses a flexible camera to examine the oesophagus, stomach and upper portion of the small intestine. It can help doctors investigate symptoms such as persistent heartburn, swallowing difficulties, upper abdominal pain, ulcers or suspected gastrointestinal bleeding.

Colonoscopy

Colonoscopy allows the doctor to examine the lining of the colon and rectum. It may be recommended to investigate changes in bowel habits, rectal bleeding, unexplained anaemia, abdominal symptoms or to screen for colorectal abnormalities when appropriate.

ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a specialised endoscopic procedure used to evaluate and treat certain problems involving the bile ducts and pancreatic ducts. It can be used in selected cases involving bile duct stones, strictures and obstruction.

Other Gastroenterology Investigations

Depending on the clinical situation, evaluation may also involve:

• Capsule endoscopy
• Endoscopic ultrasound (EUS)
• Sigmoidoscopy
• Liver function tests
• Stool and blood investigations
• Ultrasound and other abdominal imaging
• FibroScan or liver stiffness assessment where clinically indicated

The appropriate test depends on the patient's symptoms, medical history and examination findings.

When Should You See a Gastroenterologist?

Consider consulting a gastroenterologist when digestive symptoms are persistent, recurrent or unexplained. Common reasons for consultation include ongoing abdominal pain, frequent acidity or heartburn, difficulty swallowing, recurrent vomiting, persistent diarrhoea or constipation, blood in the stool, unexplained weight loss, jaundice or abnormal liver tests.

A gastroenterologist specialises in diseases of the gastrointestinal tract and liver and can determine whether further testing or specialist treatment is necessary.

Personalised Digestive Health Management

Treatment in Gastro Sciences depends on the specific diagnosis, severity of symptoms and overall health of the patient. Management may include dietary and lifestyle modifications, medicines, monitoring, endoscopic treatment or coordination with other specialists when surgery or advanced care is required.

For chronic conditions such as GERD, IBS, inflammatory bowel disease, fatty liver or cirrhosis, ongoing follow-up may be important. Patients should follow the treatment plan recommended by their healthcare professional and avoid taking long-term medicines without appropriate medical advice.

Frequently Asked Questions About Gastro Sciences

What does Gastro Sciences include?

Gastro Sciences primarily covers gastroenterology and digestive health, including disorders of the oesophagus, stomach, intestines, colon, liver, pancreas, gallbladder and bile ducts.

What does a gastroenterologist treat?

A gastroenterologist treats a wide range of digestive and liver conditions, including acid reflux, gastritis, peptic ulcers, IBS, inflammatory bowel disease, liver disorders, pancreatitis and gallbladder or biliary diseases.

Is endoscopy used to diagnose stomach problems?

Yes. Upper GI endoscopy can allow a doctor to directly examine the oesophagus, stomach and upper small intestine and investigate several digestive conditions.

What is the difference between gastroenterology and surgical gastroenterology?

Medical gastroenterology primarily focuses on diagnosis, medicines and endoscopic management of digestive and liver diseases. Surgical gastroenterology deals with conditions that require surgical treatment. Some patients may need coordinated care between gastroenterologists and GI surgeons.

When should abdominal pain be evaluated by a gastroenterologist?

Persistent, recurrent or unexplained abdominal pain should be medically evaluated, particularly when accompanied by symptoms such as vomiting, bleeding, unexplained weight loss, fever, jaundice or significant changes in bowel habits.
