Dr. Campbell David Davies diagnoses and treats a wide range of digestive system disorders, including:
Esophageal, Stomach & Upper GI Disorders
- Barrett's Esophagus & Dysplasia Monitoring: A precancerous condition in which the normal lining of the esophagus is replaced with tissue similar to the intestinal lining, often due to chronic GERD, requiring regular surveillance for dysplasia (abnormal cells).
- Hiatal Hernia & Paraesophageal Hernia: Condition where part of the stomach pushes upward through an opening (hiatus) in the diaphragm into the chest, potentially contributing to GERD and other symptoms.
- Dysphagia (Difficulty Swallowing) & Odynophagia (Painful Swallowing): Symptoms requiring investigation to determine underlying causes, which can range from structural abnormalities and motility disorders to inflammatory conditions or tumors.
Small & Large Intestine (Colorectal) Disorders
- Celiac Disease & Gluten Sensitivity: Celiac disease is an autoimmune disorder triggered by gluten ingestion, damaging the small intestine. Non-celiac gluten sensitivity involves GI symptoms related to gluten without the autoimmune damage.
- Irritable Bowel Syndrome (IBS) - All Subtypes (IBS-D, IBS-C, IBS-M, IBS-U): A common functional gastrointestinal disorder affecting the large intestine, causing symptoms like cramping, abdominal pain, bloating, gas, and changes in bowel habits (diarrhea, constipation, or mixed).
- Small Intestinal Bacterial Overgrowth (SIBO) & Intestinal Methanogen Overgrowth (IMO): An abnormal increase in the bacterial population in the small intestine, or an overgrowth of methane-producing archaea, leading to symptoms like bloating, gas, abdominal pain, and altered bowel habits.
Functional Gastrointestinal & Motility Disorders
- Cyclic Vomiting Syndrome: A disorder characterized by recurrent, stereotypical episodes of intense nausea and vomiting lasting for hours or days, with symptom-free intervals in between.
- Functional Dyspepsia & Epigastric Pain Syndrome: Persistent or recurrent pain or discomfort centered in the upper abdomen (dyspepsia) or specifically in the epigastric region, without an identifiable structural cause after investigation.
This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Campbell David Davies.
- Helicobacter pylori (H. pylori) Testing & Eradication Therapy: Diagnosis of H. pylori infection using breath tests, stool tests, or endoscopic biopsies, and providing appropriate antibiotic regimens for eradication to treat ulcers and gastritis.
- Management of Chronic Constipation & Chronic Diarrhea (idiopathic & secondary): Systematic investigation into underlying causes (including motility testing where appropriate) and tailored treatment strategies for persistent constipation or diarrhea not attributed to other major GI diseases.
- Capsule Endoscopy (Small Bowel & Colon): Non-invasive procedure where the patient swallows a vitamin-pill sized camera that takes pictures of the small intestine (for obscure GI bleeding, Crohn's disease) or colon (as an alternative to colonoscopy in select cases).
- Endoscopic Ultrasound (EUS) with Fine Needle Aspiration/Biopsy (FNA/FNB): Procedure combining endoscopy with ultrasound to obtain high-resolution images and tissue samples (FNA/FNB) of the digestive tract wall, surrounding organs (pancreas, liver, adrenal glands, gallbladder), and lymph nodes for staging cancers or diagnosing lesions.
- Endoscopic Dilation of Gastrointestinal Strictures (Esophageal, Pyloric, Colonic): Procedure to stretch narrowed areas (strictures) in the esophagus (e.g., due to reflux, EoE), stomach outlet (pylorus), small intestine, or colon using balloons or Savary-Gilliard dilators passed through an endoscope.
- Personalized Nutritional Assessment & Medical Dietary Therapy for GI Conditions: Evaluation of nutritional status and provision of evidence-based dietary advice and medical nutrition therapy tailored to specific gastrointestinal disorders like IBD, IBS, celiac disease, eosinophilic esophagitis, gastroparesis, or food intolerances, often in collaboration with registered dietitians.
- ERCP (Endoscopic Retrograde Cholangiopancreatography) - Diagnostic & Therapeutic: Specialized procedure combining upper endoscopy and X-rays to diagnose and treat problems of the bile and pancreatic ducts, such as gallstone removal from bile duct, stent placement for strictures or leaks, and sphincterotomy.

- Are consultations and procedures like endoscopies with Dr. Davies, a Gastroenterologist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?
- Medically necessary consultations with a licensed Gastroenterologist like Dr. Davies, as well as most diagnostic procedures (e.g., endoscopies for investigating symptoms, biopsies for medical reasons) and treatments for provincially insured digestive conditions (e.g., IBD, celiac disease, screening colonoscopies as per provincial guidelines, liver disease management), are generally covered by Régie de l'assurance maladie du Québec (RAMQ) in QC when a referral from a family doctor or another specialist is in place. Procedures considered purely for screening outside of guidelines, or for non-medical reasons, and some advanced technologies or specific drug therapies might have different coverage. It's crucial to discuss coverage specifics for any proposed treatment or procedure with Dr. Davies's office, the hospital/clinic's financial services, or Régie de l'assurance maladie du Québec (RAMQ) beforehand.
- Do I need a referral from my family doctor to see Dr. Davies, a Gastroenterologist?
- Yes, in nearly all cases, a referral from your family physician or another specialist (such as an internist or surgeon) is required to schedule an appointment with a Gastroenterologist like Dr. Davies for services covered by the provincial health plan. Gastroenterological issues often require initial assessment and preliminary investigations by your primary care provider. The referral ensures that a specialist consultation is appropriate, helps with prioritizing appointments, and facilitates coordinated care, including the transfer of relevant medical information.
- Are there significant risks associated with procedures like gastroscopy or colonoscopy?
- Gastroscopy (upper endoscopy) and colonoscopy are generally very safe procedures, especially when performed by an experienced Gastroenterologist like Dr. Dr. Davies. Complications are uncommon. Potential risks can include bleeding, particularly if polyps are removed or biopsies are taken; perforation (a tear in the wall of the digestive tract); infection (rare); or adverse reactions to the sedative medication used. Before your procedure, Dr. Dr. Davies will thoroughly discuss the specific potential risks and benefits based on your individual health and the reason for the procedure, allowing you to make an informed decision.
- What is generally involved in preparing for a colonoscopy procedure?
- Preparing for a colonoscopy is a critical step to ensure the procedure is effective and safe. Dr. Dr. Davies's office will provide very specific instructions, which must be followed closely. Typically, preparation involves dietary changes for a few days beforehand (e.g., low-residue diet), followed by a clear liquid diet for the 24 hours prior to the exam. The most important part is the bowel cleansing process, which involves drinking a prescribed laxative solution designed to completely empty and clean your colon. This usually starts the evening before and may continue the morning of the procedure. You'll also need to arrange for transportation home, as sedation is commonly used.
