Dr. Madeleine Bonneviot diagnoses and treats a wide range of digestive system disorders, including:

Esophageal, Stomach & Upper GI Disorders

• Gastroesophageal Reflux Disease (GERD) / Acid Reflux / Heartburn: Chronic condition where stomach acid frequently flows back into the esophagus, causing heartburn, regurgitation, chest pain, and potential complications like esophagitis.
• Esophageal Motility Disorders (e.g., Achalasia, Esophageal Spasms, Nutcracker Esophagus): Disorders affecting the coordinated muscle movements of the esophagus required for swallowing, leading to symptoms like dysphagia (difficulty swallowing), chest pain, and regurgitation.

Functional Gastrointestinal & Motility Disorders

• Rumination Syndrome: A condition in which people repeatedly and unintentionally spit up (regurgitate) undigested or partially digested food from the stomach, rechew it, and then reswallow it or spit it out.
• 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.
• Chronic Idiopathic Constipation (CIC) & Opioid-Induced Constipation (OIC): Persistent constipation that does not have an identifiable underlying cause (CIC) or is a side effect of opioid medications (OIC).

Inflammatory Bowel Disease (IBD) Focus

• Ulcerative Colitis (Proctitis, Left-sided Colitis, Pancolitis): A chronic inflammatory condition that causes inflammation and ulcers primarily in the lining of the large intestine (colon and rectum), typically presenting with bloody diarrhea, urgency, and abdominal pain.
• Indeterminate Colitis & IBD-Unclassified (IBD-U): Cases of IBD, particularly early in the disease course, where it is difficult to definitively distinguish between Crohn's disease and ulcerative colitis based on clinical, endoscopic, and histological features.

This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Madeleine Bonneviot.

• Interpretation & Correlation of Advanced Digestive Health Diagnostic Tests: Expert analysis and clinical correlation of results from endoscopies, biopsies, imaging studies (CT, MRI, MRCP, ultrasound), breath tests (e.g., for H. pylori, SIBO, lactose intolerance), stool tests (e.g., calprotectin, FIT), motility studies, and genetic testing for GI conditions.
• Enteroscopy (e.g., Double-Balloon, Single-Balloon, Spiral Enteroscopy): Advanced endoscopic techniques allowing deep visualization, biopsy, and therapy within the small intestine, beyond the reach of standard endoscopes, for conditions like obscure bleeding or small bowel tumors.
• 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).
• 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.
• Flexible Sigmoidoscopy with Biopsy: Examination of the lower part of the colon (sigmoid colon and rectum) using a flexible sigmoidoscope, often for evaluation of rectal bleeding, diarrhea, or as part of some screening protocols.
• Chromoendoscopy & Advanced Imaging Techniques (e.g., NBI, FICE): Use of special dye sprays (chromoendoscopy) or electronic light filters (Narrow Band Imaging, Fuji Intelligent Chromo Endoscopy) during endoscopy to enhance visualization of mucosal patterns and improve detection of subtle lesions or precancerous changes.
• Second Opinion Consultations for Complex Digestive Diseases: Providing expert second opinions on challenging or rare gastrointestinal diagnoses, unclear test results, and proposed complex treatment plans, including for IBD, liver disease, and pancreatic disorders.

Are consultations and procedures like endoscopies with Dr. Bonneviot, a Gastroenterologist, covered by Régie de l'assurance maladie du Québec (RAMQ) in QC?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Bonneviot, 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. Bonneviot'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. Bonneviot, 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. Bonneviot 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.

How does a Gastroenterologist like Dr. Bonneviot approach the management of Inflammatory Bowel Disease (IBD)?

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Bonneviot is a highly individualized and long-term process. The primary goals are to induce and then maintain remission (control inflammation), alleviate symptoms, prevent complications, and improve the patient's overall quality of life. Treatment strategies often involve a combination of medications, which can include aminosalicylates (5-ASAs), corticosteroids (for acute flare-ups), immunomodulators (e.g., azathioprine, methotrexate), and increasingly, biologic therapies or small molecule drugs that target specific inflammatory pathways. Regular monitoring through clinical assessment, blood tests, stool tests (like fecal calprotectin), and endoscopic procedures is crucial to track disease activity and adjust treatment as needed. Nutritional counseling and lifestyle advice are also integral parts of comprehensive IBD care.
