Your gut is critical to your overall health, extending far beyond just digestion.Often referred to as the “second brain,” the gut is home to a complex and dynamic ecosystem of trillions of microorganisms, collectively known as the gut microbiota.
This intricate community of microbes work in harmony to influence not only digestion but also a wide range of bodily functions.
Island Hospitals’ Gastroenterology FAQs provide valuable insights into common digestive concerns and offer expert guidance on nurturing a healthy gut for optimal well-being.
Let’s dive into the details.
Organs within the Gastroenterologist’s Scope:
(a) Gastrointestinal (GI) Tract
- Esophagus: The tube connecting the mouth to the stomach.
- Stomach: Where food is initially broken down.
- Small Intestine: Where most nutrient absorption occurs.
- Large Intestine (Colon): Primarily responsible for water absorption and waste formation.
- Rectum: The final part of the large intestine, storing stool before elimination.
(b) Accessory Organs
- Bile Ducts: Transport bile from the liver and gallbladder to the small intestine.
- Gallbladder: Stores and releases bile.
- Pancreas: Secretes digestive enzymes and hormones like insulin.
- Liver: Produces bile for fat digestion and detoxification.
2. What conditions do they treat?
Gastroenterologists treat a wide range of conditions affecting the digestive system, from the mouth to the anus. Some of the common conditions your gastroenterologists may treat are:
| Type of Conditions | Examples |
|---|---|
| Esophageal Disorders | |
| Gallbladder Diseases | |
| Large Intestine Disorders | |
| Liver Diseases | |
| Pancreatic Diseases | |
| Small Intestine Disorders | |
| Stomach Disorders | |
| Other Conditions |
3. What procedures and tests do they perform?
At Island Hospital, our expert gastroenterologists provide top-quality care. We offer both in-clinic consultations and advanced procedures such as:

- Endoscopic Retrograde Cholangiopancreatography (ERCP)
- Fibroscan of Liver
- Gastroscopy
- Gastroesophageal Reflux Disease (GERD)
- Liver Disease
4. Do gastroenterologists perform surgery?
Gastroenterologists (GI doctors) commonly perform endoscopic procedures like colonoscopies but don’t typically perform surgery. They focus on non-surgical treatments, such as medication, diet, and lifestyle changes, and perform procedures like endoscopies to diagnose and treat conditions within the digestive tract.
On the other hand, gastroenterologists play a critical role in diagnosing conditions that may require surgery and often work closely with surgeons to ensure comprehensive patient care.
Endoscopic procedures are minimally invasive techniques used to examine, diagnose, and treat conditions within the digestive tract.
These procedures involve the use of an endoscope—a flexible tube equipped with a light and camera—that allows the doctor to visualize the internal organs and perform interventions without the need for large incisions. Common endoscopic procedures include:
- Colonoscopy
- Capsule Endoscopy
- Endoscopic Ultrasound (EUS)
- Upper Endoscopy (EGD)
However, if a surgical procedure is necessary, your gastroenterologist will refer you to a surgeon, such as a colorectal surgeon, who specializes in surgical interventions for digestive system conditions.
For example, if a colonoscopy reveals a large polyp that cannot be removed endoscopically or if a biopsy confirms cancer, the gastroenterologist will refer the patient to a general surgeon or a specialized surgeon, such as a colorectal surgeon, hepatobiliary surgeon, or bariatric surgeon, depending on the condition.

FAQs About Digestive Health
1. What are the warning signs of gastrointestinal disorders?
Gastrointestinal disorders can cause a wide range of symptoms, and some of the most common warning signs include:
- Abdominal pain or discomfort: This may range from mild cramps to severe pain
- Bloating or gas: Feeling full or having excessive gas can be a sign of a GI issue.
- Changes in bowel habits: This includes constipation, diarrhea, or changes in the consistency of your stool.
- Difficulty swallowing: This can be a sign of a number of conditions, including GERD, esophageal stricture, and esophageal cancer.
- Fatigue: Feeling constantly tired.
- Nausea or vomiting: Frequent nausea or vomiting can be a warning sign.
- Rectal bleeding or blood in your stool: This is a serious symptom that should not be ignored as it may be a sign of colorectal cancer.
- Unexplained weight loss: Losing weight without trying can be a sign of a GI disorder.
Lingering digestive discomfort shouldn’t be ignored. It could signal a more serious gastrointestinal problem. If you’re experiencing any troubling digestive symptoms, it’s essential to see a doctor for diagnosis and a treatment plan to prevent potential complications.
2. When should you see a Gastroenterologist?
In the event of any of the above signs or symptoms, it is advisable to seek medical attention from a gastroenterologist. An annual check-up is recommended for those at risk for GI disorders such as:
- Individuals aged 45 or older
The American College of Gastroenterology recommends that everyone begin colorectal cancer screening at age 45 due to the rising incidence of the disease in people in their 40s. - Family history of colorectal cancer
If you have a family history of colorectal cancer, you may need to see a gastroenterologist for screening, as inherited genetic mutations can sometimes cause it. - Individuals experiencing persistent or concerning symptoms
If you notice ongoing or worrisome signs such as unexplained weight loss, persistent abdominal pain, changes in bowel habits, or blood in the stool, it is crucial to seek medical attention promptly.
A gastroenterologist can help identify the underlying cause and recommend appropriate treatment.
3. What are the early signs of colon cancer?
Colon cancer often develops without any noticeable symptoms in its early stages. This is why regular screening is so important. However, as the cancer progresses, some signs and symptoms may appear:
- Changes in bowel habits
- Fatigue or weakness
- Feeling that your bowel doesn’t empty completely
- Persistent abdominal discomfort
- Rectal bleeding or blood in stool
- Unexplained weight loss
It’s important to note that:
- These symptoms can be vague and easily dismissed. Many people attribute them to other, less serious conditions.
- The earlier colon cancer is detected, the more treatable it is.
- Regular screening is crucial, even if you don’t have any symptoms as screening can help find precancerous polyps or early-stage cancer, which can be removed before they become more advanced.
4. When should I seek professional help for acid reflux?
While occasional heartburn is common, worsening or increasingly frequent episodes warrant a visit to your doctor. See your doctor if you experience any of the following heartburn or GERD (gastroesophageal reflux disease) symptoms:
- Worsening or more frequent heartburn
- Difficulty or pain when swallowing (particularly with solid foods or pills)
Oesophageal cancer is the 8th most common cancer worldwide. Learn more about this digestive disease in our in-depth article: Oesophageal Cancer: What You Need to Know.
FAQs About Appointments and Preparation
1. What should I expect during my first visit?
Your first visit to a gastroenterology clinic will involve a few key components designed to help your doctor understand your digestive health concerns and create a personalized treatment plan. Here’s a general idea of what you can expect:
- Medical History Review
Your gastroenterologist will thoroughly review your medical history, including past illnesses, surgeries, medications (prescription and over-the-counter, including supplements), allergies, and any family history of GI diseases, especially colorectal cancer.
- Symptom Discussion
You’ll discuss your current symptoms in detail, including when they started, how often they occur, what makes them better or worse, and any other related concerns. Be as specific as possible. For example, instead of saying “stomach pain,” describe the location, type (sharp, dull, cramping), and any associated factors (eating, bowel movements, stress).
- Physical Examination
Your gastroenterologist will perform a physical examination, which may include listening to your abdomen with a stethoscope, palpating (feeling) your abdomen to check for tenderness or abnormalities, and possibly a rectal exam.
- Discussion of Potential Diagnoses and Tests
Based on your history and exam, the doctor will discuss potential diagnoses and recommend appropriate tests. These could include blood tests, stool tests, imaging studies (like an ultrasound or CT scan), or endoscopic procedures (like an upper endoscopy or colonoscopy).
- Initial Treatment Plan (Potentially)
Sometimes, the doctor can offer initial treatment recommendations even before test results are available. This might involve dietary changes, lifestyle modifications, or medications.
Don’t hesitate to ask your doctor about its purpose, the procedure itself, and what you can expect before, during, and after. Understanding these details is an important part of your healthcare journey.
2. How do I make an appointment with a gastroenterologist?
Making an appointment with a gastroenterologist is easy. Here are your options:
- Referral from your primary care physician
This is often the first step. Your primary care doctor can assess your symptoms and provide a referral to a gastroenterologist if they suspect a GI issue. A referral may also be required by your insurance provider for coverage of specialist visits.
- Online appointment scheduling
Scheduling a gastroenterology appointment is easier than ever with online portals available at many hospitals and clinics, including Island Hospital. Island Hospital’s online booking system makes it especially simple, requiring only three steps.
- Hospital Websites
If you prefer to see a gastroenterologist affiliated with a specific hospital, you can visit the hospital’s website and search for doctors in their network.
3. How should you prepare for a gastrointestinal procedure?
Preparation for a gastroenterology procedure is crucial for accurate results and patient comfort. The specific preparation depends heavily on the type of procedure you’re undergoing, but some common elements include:
- Fasting: Many endoscopic procedures, such as upper endoscopy and colonoscopy, require fasting (no food or drink, including water) for several hours beforehand. This ensures a clear digestive tract for accurate visualization and minimizes risks. Follow your doctor’s fasting instructions carefully.
- Bowel Prep: A thorough bowel prep is necessary for procedures like colonoscopies and sigmoidoscopies. This involves using a prescribed laxative to empty the colon, ensuring clear visualisation for the doctor. Carefully follow your doctor’s instructions, including any dietary restrictions.
- Medication Adjustments: Some medications (e.g., blood thinners, aspirin, diabetes meds) may need adjusting or stopping before a GI procedure due to bleeding or anesthesia risks. It is important to tell your doctor about all medications and supplements you take.
4. What happens after a gastrointestinal procedure?
What happens after a gastrointestinal procedure depends significantly on the specific procedure performed. However, there are some general things you can expect:
- After a GI procedure, you’ll be monitored in a recovery area as you wake up, and nurses will check your vital signs. Some may have initial discomfort, which your medical team will manage, and you’ll receive detailed instructions for at-home care, including diet, activity, medications, and follow-up appointments.
- Your doctor will provide specific instructions regarding diet, activity restrictions, and prescribed medications to ensure proper healing. You will have to closely monitor for potential complications like bleeding, pain, or fever, and attend your scheduled follow-up appointment to discuss results and recovery.
5. Is an overnight hospital stay necessary for a colonoscopy screening?
An overnight hospital stay is generally unnecessary for a routine colonoscopy screening. Colonoscopies are typically performed on an outpatient basis, meaning you’ll go home the same day.
The procedure usually takes less than an hour, and while you’ll need some time to recover from the sedation, most people are discharged within a few hours.
However, there are some exceptions where an overnight stay could be recommended, such as if complications arise during the procedure or individual circumstances necessitate an overnight stay.
