Dr. Johane Allard diagnoses and treats a wide range of digestive system disorders, including:
Liver, Gallbladder, Bile Duct & Pancreatic Disorders
- Cirrhosis & Management of Its Complications (Ascites, Varices, Encephalopathy): Advanced stage of liver scarring (fibrosis) impairing liver function, leading to complications such as fluid accumulation in the abdomen (ascites), enlarged veins that can bleed (varices), and brain dysfunction (hepatic encephalopathy).
- Non-Alcoholic Fatty Liver Disease (NAFLD) & Non-Alcoholic Steatohepatitis (NASH): A spectrum of conditions characterized by excessive fat accumulation in the liver not caused by alcohol. NASH involves liver inflammation and cell damage and can progress to cirrhosis.
- Pancreatitis (Acute Recurrent & Chronic): Inflammation of the pancreas that can be sudden and severe (acute), recurrent, or long-lasting (chronic), causing significant abdominal pain and digestive enzyme deficiencies.
Esophageal, Stomach & Upper GI Disorders
- Gastritis (Inflammation of Stomach Lining) & Duodenitis: Inflammation of the stomach lining (gastritis) or the first part of the small intestine/duodenum (duodenitis), which can be acute or chronic and caused by various factors including infection, irritants, or autoimmune processes.
- Eosinophilic Esophagitis (EoE): A chronic immune system disease characterized by a buildup of eosinophils (a type of white blood cell) in the esophagus, causing inflammation, difficulty swallowing, food impaction, and chest pain.
Small & Large Intestine (Colorectal) Disorders
- 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.
- 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.
This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Johane Allard.
- 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.
- Gastrointestinal Motility Disorder Evaluation & Management Coordination: Initial evaluation of symptoms suggestive of GI motility disorders (e.g., gastroparesis, achalasia, chronic intestinal pseudo-obstruction), with coordination for specialized testing like esophageal manometry, antroduodenal manometry, wireless motility capsule, or gastric emptying studies, and subsequent management strategies.
- 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.
- 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.
- 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.
- 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.
- Comprehensive Gastroenterology Consultation & Digestive Health Assessment: In-depth assessment of digestive system disorders, including detailed review of medical history, family history, lifestyle factors, physical examination, symptom analysis, and development of a personalized diagnostic and treatment strategy.
Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Allard for care relevant to your specific condition.

- Are consultations and procedures like endoscopies with Dr. Allard, a Gastroenterologist, covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary consultations with a licensed Gastroenterologist like Dr. Allard, 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 Ontario Health Insurance Plan (OHIP) in ON 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. Allard's office, the hospital/clinic's financial services, or Ontario Health Insurance Plan (OHIP) beforehand.
- Do I need a referral from my family doctor to see Dr. Allard, 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. Allard 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. Allard approach the management of Inflammatory Bowel Disease (IBD)?
- The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Allard 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 an integral part of comprehensive IBD care.
- 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. Allard'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.
- What's the difference between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)? Can Dr. Allard diagnose and treat both?
- Yes, a Gastroenterologist like Dr. Allard can diagnose and treat both IBS and IBD, but they are very different conditions. IBD, which includes Crohn's disease and ulcerative colitis, is characterized by chronic inflammation and physical damage (like ulcers and strictures) to the digestive tract, visible during endoscopy and on biopsies. It's an autoimmune-related condition. IBS, on the other hand, is a functional gut disorder, meaning the GI tract doesn't work correctly, but there's no visible inflammation or damage on standard tests. IBS causes symptoms like abdominal pain, bloating, and altered bowel habits. While IBS can significantly impact quality of life, it doesn't cause the destructive inflammation seen in IBD. Diagnosis involves different criteria and investigations for each.
