What Is Gastroenterology?
Request Call Back
Overview
Gastroenterology is a medical specialty focused on the diagnosis, treatment, prevention, and long-term management of diseases related to the digestive system—from the mouth to the anus. This includes not only the stomach and intestines, but also key digestive organs such as the liver, pancreas, and gallbladder.
At MedicalPoint Hospital, our board-certified gastroenterologists evaluate both functional and structural disorders of the gastrointestinal (GI) tract and use advanced diagnostic tools and minimally invasive procedures to restore optimal digestive health.
Organs Covered in Gastroenterology
The digestive system, or gastrointestinal tract, transforms food into energy and eliminates waste. Gastroenterology covers a wide range of organs, including:
- Mouth, esophagus, stomach
- Small intestine (duodenum, jejunum, ileum)
- Colon (large intestine), rectum, and anus
- Liver, pancreas, gallbladder, and bile ducts
Though the term “gastro” (stomach) and “entero” (intestine) form the word gastroenterology, this specialty encompasses the entire digestive ecosystem.
What Conditions Do Gastroenterologists Treat?
Gastroenterology is a subspecialty of internal medicine. At MedicalPoint, our gastroenterologists diagnose and treat a wide array of conditions, including:
1. Irritable Bowel Syndrome (IBS)
A functional disorder affecting bowel movements—causing abdominal pain, bloating, constipation, or diarrhea. Dietary changes, including increased fiber intake, are often effective.
2. Constipation
A common digestive complaint affecting millions. It occurs when the colon absorbs too much water, making stool hard and difficult to pass. It may stem from low fiber diets, but can also signal more serious issues such as colorectal cancer.
3. Diarrhea
Frequent, loose stools often linked to infections (gastroenteritis) or chronic conditions like ulcerative colitis or Crohn’s disease. Untreated diarrhea can lead to dehydration and electrolyte imbalance.
4. Gastroesophageal Reflux Disease (GERD)
Occurs when stomach acid backs up into the esophagus due to a weakened sphincter. Symptoms include heartburn, chest pain, and regurgitation. Untreated, GERD can lead to esophageal damage or cancer.
5. Peptic Ulcers
Caused by Helicobacter pylori infection or long-term NSAID use. Ulcers damage the stomach’s protective lining, resulting in pain, bloating, and burning sensations.
Additional Conditions:
- Gallstones and gallbladder disease
- Fatty liver disease and hepatitis
- Gastric and colorectal cancers
- Diverticulitis
- Pancreatic disorders
Our team combines medical management with nutritional and lifestyle support to deliver holistic care for all digestive health conditions.
Common Symptoms That Warrant Gastroenterology Care
Patients often visit the gastroenterology department with the following symptoms:
- Persistent abdominal pain
- Bloating, gas, or indigestion
- Constipation or diarrhea
- Nausea and vomiting
- Heartburn or acid reflux
- Unexplained weight loss
- Jaundice (yellowing of the skin or eyes)
These symptoms may indicate minor issues or be early signs of more serious diseases. Early evaluation can prevent complications.
How Are Gastrointestinal Disorders Diagnosed?
Gastroenterologists at MedicalPoint use a range of tools to accurately diagnose GI conditions:
1. Blood Tests
Evaluate organ function (e.g., liver enzymes like ALT and AST) and detect signs of inflammation or infection.
2. Endoscopy
A thin, flexible tube with a camera is used to examine the esophagus, stomach, and upper small intestine for ulcers, tumors, or inflammation.
3. Colonoscopy
Provides detailed visualization of the colon and rectum. It is essential for colon cancer screening, polyp detection, and diagnosing inflammatory bowel disease.
4. Imaging Studies
Ultrasound, abdominal CT scans, and MRI may be used to assess the liver, gallbladder, or pancreas.
5. Biopsy
During endoscopic procedures, suspicious tissue samples may be taken for lab analysis to confirm a diagnosis.
Gastroenterological Surgery
While many digestive diseases can be managed non-surgically, some require surgical intervention. At MedicalPoint Hospital, we offer:
- Laparoscopic Surgery: Minimally invasive techniques for gallstones, GERD, and more.
- Endoscopic Polypectomy: Removal of polyps during colonoscopy or endoscopy.
- Open Surgery: Reserved for complex conditions such as cancer or severe inflammatory diseases.
Our surgeons collaborate closely with gastroenterologists to provide seamless, integrated care.
When Should You See a Gastroenterologist?
Consider visiting a specialist if you:
- Experience persistent digestive symptoms
- Have blood in your stool
- Are over 45 and require routine colon cancer screening
- Have a family history of GI cancers or liver disease
- Live with a chronic condition like IBD, GERD, or hepatitis
Early evaluation and intervention can significantly improve outcomes and prevent disease progression.
