What Does a Gastroenterologist Do, and Why Is Digestive Health Important?
A gastroenterologist is a medical expert specialising in the diagnosis and treatment of digestive system disorders, including issues with the oesophagus, stomach, intestines, liver, and pancreas.
What Are the Symptoms that Require an Immediate Visit to a Gastroenterologist?
A. Persistent Digestive Symptoms
- Frequent Abdominal Pain: Repeated stomach pain, cramps, or bloating could signal underlying conditions like ulcers, IBD, or even food intolerances. Ignoring these symptoms can lead to worsening of the condition over time.
- Chronic Heartburn or Acid Reflux: Persistent reflux that lasts for weeks or disrupts your sleep could indicate gastroesophageal reflux disease (GERD), which can cause oesophageal damage if untreated.
- Unexplained Nausea or Vomiting: Persistent vomiting or nausea without an apparent cause should not be overlooked, as it may indicate a serious digestive disorder such as infections, or gastrointestinal blockages.
B. Irregular Bowel Movements
- Chronic Diarrhoea or Constipation: While occasional digestive upset is normal, prolonged diarrhoea or constipation could point to underlying issues such as IBS, infections, or inflammatory bowel diseases like Crohn’s or ulcerative colitis.
- Presence of Blood in Stool: Blood in your stool could be a symptom of haemorrhoids, infections, or even colorectal cancer, necessitating immediate medical attention.
C. Concerning Weight Changes
- Unexplained Weight Loss: Sudden, unexplained weight loss can signal serious conditions, including cancers, chronic infections, or malabsorption issues that prevent the body from absorbing nutrients properly.
- Difficulty Swallowing (Dysphagia): Also known as dysphagia, difficulty swallowing can be related to problems in the oesophagus, such as strictures, inflammation, or even tumours.
What Conditions Do Gastroenterologists Treat?
Gastroenterologists diagnose and treat a variety of digestive disorders. Here are some of the most common:
- Gastroesophageal Reflux Disease (GERD): A condition where stomach acid flows back into the oesophagus. Symptoms include heartburn and sour taste in the mouth.
- Haemorrhoids: Swollen veins in the anus and rectum. Symptoms include bleeding, itching, and pain.
- Inflammatory Bowel Disease (IBD): A group of disorders that cause inflammation in the digestive tract. Symptoms include abdominal pain, diarrhoea, and fatigue.
- Irritable Bowel Syndrome (IBS): A common disorder that affects the large intestine. Symptoms include abdominal pain, bloating, and changes in bowel habits.
- Colorectal Cancer: A cancer that begins in the colon or rectum. Symptoms include changes in bowel habits, bleeding, and abdominal pain.
- Diverticulitis: Inflammation of small pouches in the colon. Symptoms include abdominal pain, fever, and changes in bowel habits.
Diagnostic Tests:
- Blood Tests: To check for inflammation, infection, or other underlying conditions.
- Stool Tests: To identify infections, inflammation, or bleeding.
- Endoscopy: To visualise the inside of the digestive tract.
- Colonoscopy: To examine the colon and rectum.
- Imaging Tests: Such as CT scans and MRIs to assess organ health.
- Abdominal Ultrasound: To create detailed images of the organs and structures inside the abdomen.
Treatment Options:
Treatments vary depending on the specific condition, but may include:
- Medication: To reduce inflammation, acid production, or pain.
- Dietary Changes: To manage symptoms and promote healing.
- Lifestyle Modifications: Such as weight loss and stress management.
- Surgery: In severe cases, surgical intervention may be necessary.
If you are experiencing digestive symptoms, consult a gastroenterologist for accurate diagnosis and treatment.
When Is Routine Screening Recommended?
Routine screening plays a vital role in the early detection and prevention of digestive conditions. Routine colorectal cancer screening should begin at age 45. Colonoscopies are recommended at regular intervals or more frequently if there is an increased risk of colorectal cancer.
