The cooperation and coordination of organs in the human body are essential for maintaining vital functions. The combination of these movements creates systems in the body. One of these systems in the human body is the digestive system, which starts from the mouth and ends in the anus. Gastroenterology is the branch of science that studies the digestive system organs such as the esophagus, stomach, intestines, and colon, as well as organs that help digestion such as the liver, pancreas, and gallbladder. The department of gastroenterology specializes in diagnosing and treating health problems in the digestive system organs such as the stomach and intestines, as well as in organs commonly known as digestive helpers, such as the liver, gallbladder, and pancreas. These problems are handled by a team of expert doctors in the field.
What Does a Gastroenterologist Do?
Gastroenterologists are medical doctors who specialize in conditions concerning the digestive system and understanding the symptoms' underlying causes. They work with patients who have digestive issues such as stomach pain, diarrhea, constipation, heartburn, and other symptoms. They specialize in treating severe conditions such as IBS, hepatitis, and cancer of the digestive system.
Gastroenterologists use various diagnostic tools and techniques to evaluate and treat their patients. These may include endoscopy, colonoscopy, and biopsy. They may also need blood tests to see how the body is coping with the issues, followed by X-rays or other imaging tests to help diagnose a condition. Gastroenterologists often work closely with other healthcare professionals, such as nurses, dietitians, and primary care doctors, to create and formulate a treatment plan for their cases. They often consult with other specialists, such as general surgeons, in critical and severe cases where surgery is the only option.
Methods of Diagnosis in Gastroenterology
The most effective diagnostic method in gastroenterology is endoscopy, which is the visualization of the interior of the body with specially developed optical devices. Endoscopy is the name given to the visualization of the inside of the body. Depending on the area being visualized, it may be referred to by different names such as gastroscopy or colonoscopy. The main diagnostic methods used in the gastroenterology department can be listed as follows:
- Upper gastrointestinal endoscopy (UGIE): Imaging methods such as ultrasonography and tomography can be insufficient for accurate diagnosis of digestive system diseases. In these cases, imaging methods such as upper gastrointestinal endoscopy are utilized. UGIE is an endoscopic procedure that allows for examination of the upper part of the gastrointestinal system. UGIE imaging allows for visualization of the esophagus, stomach, and duodenum (esophagus, stomach and duodenum) and the diagnosis of any diseases in these organs.
- Colonoscopy: Colonoscopy is an endoscopic procedure that visualizes the colon and the large intestine with the help of a flexible and thin optical device with a camera at the end. The patient is sedated during the procedure, which is performed through the rectum, allowing the entire large intestine to be visualized.
In addition to these, also some lab tests are used for diagnosing gastroenterology diseases.
What Health Conditions Does a Gastroenterologist Treat?
The department of gastroenterology specializes in understanding the underlying issues and causes of the problems you're facing. Whether it is fatigue or stress, or unhealthy habits like poor etiquette. Some common conditions and issues they treat include:
- Stomach pain: Gastroenterologists can help diagnose the cause of stomach pain and recommend treatment options.
- Heartburn and acid reflux: These conditions involve the backward flow of stomach acid into the esophagus, giving rise to a burning sensation in the chest. Gastroenterologists can recommend medications or lifestyle changes to help manage these conditions.
- Inflammatory bowel disease(IBD): Inflammatory Bowel Disease (IBD) is a group of chronic digestive disorders characterized by inflammation in the digestive tract. Ulcerative Colitis affects the large intestine and rectum, causing sores and inflammation along the lining of these areas. On the other hand, Crohn's Disease affects the digestive tract, mostly the small intestine, and can sometimes affect the large intestine and upper digestive tract.
- Irritable bowel syndrome (IBS): Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by recurring abdominal pain and altered bowel habits, including diarrhea, constipation or a combination of both. Unlike Inflammatory Bowel Disease (IBD), IBS does not cause any visible damage or disease in the digestive tract, but rather it is a group of symptoms that occur together.
- Constipation and diarrhea: These conditions involve changes in bowel movements and can cause discomfort and inconvenience. Gastroenterologists can recommend lifestyle changes and medications to help manage these conditions.
- Liver disease: The liver is a vital organ that performs numerous crucial functions such as breaking down food, processing and distributing nutrients. There are various forms of liver diseases that can be caused by various factors such as viruses, excessive alcohol consumption, or drug usage. One of the primary causes of liver damage are hepatitis viruses. Hepatitis viruses are a group of viruses that can cause inflammation and damage to the liver. There are different types of hepatitis viruses, such as A, B, and C. Hepatitis B and C are among the leading causes of liver failure worldwide. Chronic liver damage or scarring can lead to the development of cirrhosis, a liver condition characterized by long-lasting damage to the liver. Jaundice, which is the yellowing of the skin, can be an indication of liver disease.
- Pancreatitis: Pancreatitis refers to the inflammation of the pancreas. It can be acute, meaning it has a sudden onset and may resolve with proper treatment in a matter of days, or chronic, which is a long-standing condition that can progressively worsen over time, potentially causing permanent damage.
- Cancer: Since the field involves the entire digestive system, gastroenterologists diagnose and treat cancers of the digestive system, such as colon and esophageal cancer.
What Are Different Gastroenterology Treatments?
There are many different types of treatments used to treat gastroenterology diseases. The recommended treatment plan depends on the present condition and the doctor's diagnosis. Some common treatments used in gastroenterology include:
- Medications: Gastroenterologists may prescribe medications to treat various digestive conditions, including antibiotics for infections, anti-inflammatory drugs for inflammatory bowel disease, and acid-reducing medications for heartburn or ulcers.
- Diet and lifestyle changes: Adopting healthier diet habits and lifestyle can help manage digestive symptoms and issues. The measures include avoiding processed foods, increasing fiber intake, and staying hydrated.
- Endoscopy: It is a procedure that allows the doctor to examine and diagnose the digestive tract and its issues using a flexible thin tube with a light and camera. The doctor may take biopsy samples or remove polyps (growths on the digestive tract lining) during the procedure.
- Colonoscopy: It helps the doctor examine the insides of the colon. During the procedure, the doctor may take biopsy samples or remove polyps to understand the health condition of the large intestine and rectum.
- Surgery: In critical cases, surgery might be the only way to treat certain digestive conditions like a cancerous tumor or to correct a structural problem in the digestive tract.
What Are the Different Kinds of Gastroenterology Procedures?
Even though Gastroenterologists aren’t surgeons themselves, with the help of endoscopic techniques they perform many minimally invasive procedures both as imaging techniques and treatment methods. To give some examples;
GI Endoscopy: Endoscopic methods can visually distinguish healthy tissues from abnormalities. Polyps can be removed and other tissues can be biopsied.
Endoscopic Retrograde Cholangiopancreatography (ERCP): This imaging technique is the most sensitive test showing the bile ducts. A radiopaque agent is injected through bile ducts to see any anomalies in pancreas and gallbladder.
PEG Tube Placement: Percutaneous endoscopic gastrostomy (PEG) tube is used for patients who can not swallow. This operation lets patients be fed directly from their stomach.
Virtual Endoscopy and colonoscopy: A pill with a camera can be swallowed to view entirety of gastrointestinal system without a need for anesthesia or endoscopic tubes
Colorectal Cancer Screening: Usually patients with stool findings or family history are screened by gastroenterologists.
