Dr. Wen Jing Zhu diagnoses and treats a wide range of digestive system disorders, including:

Inflammatory Bowel Disease (IBD) Focus

• Crohn's Disease (Ileal, Colonic, Ileocolonic, Perianal): A chronic inflammatory condition that can affect any part of the digestive tract from mouth to anus, causing transmural (full-thickness) inflammation, pain, diarrhea, weight loss, and potential complications like strictures or fistulas.
• 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.
• Microscopic Colitis (often considered alongside IBD for chronic diarrhea): Though distinct from classic IBD, it's an inflammatory condition of the colon diagnosed by biopsy, causing chronic watery diarrhea.

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.
• Diverticular Disease (Diverticulosis, Diverticulitis, Diverticular Bleeding): Diverticulosis is the presence of small pouches (diverticula) in the colon wall. Diverticulitis is inflammation or infection of these pouches. Diverticular bleeding can also occur.
• 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.

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).
• 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.

This list is not exhaustive. For personalized advice regarding your specific digestive condition, please consult with Dr. Wen Jing Zhu.

• 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.
• 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.
• 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.
• 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.
• 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.
• Endoscopic Hemostasis for Acute & Chronic GI Bleeding: Various endoscopic techniques (e.g., injection therapy, thermal coagulation/APC, mechanical clips, hemostatic sprays) used to stop acute or recurrent bleeding from ulcers, varices, angiodysplasias, or tumors in the GI tract.

Note: This list provides a general overview. Specific procedures and treatments are determined after a thorough evaluation. Discuss with Dr. Zhu for care relevant to your specific condition.

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

Medically necessary consultations with a licensed Gastroenterologist like Dr. Zhu, 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. Zhu'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. Zhu, 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. Zhu 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. Zhu approach the management of Inflammatory Bowel Disease (IBD)?

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Zhu 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. Zhu'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 are some common procedures a Gastroenterologist like Dr. Zhu typically performs?

Gastroenterologists like Dr. Zhu are highly skilled in performing a range of endoscopic procedures. The most common are upper endoscopy (also called EGD or gastroscopy) to examine the esophagus, stomach, and duodenum, and colonoscopy to visualize the entire colon. During these procedures, she can take biopsies (small tissue samples for analysis), remove polyps (which can prevent colon cancer), dilate narrowed areas (strictures), control bleeding, and place feeding tubes. Other procedures may include flexible sigmoidoscopy (examining the lower colon), capsule endoscopy (swallowing a tiny camera to see the small intestine), and more specialized interventions like ERCP or EUS depending on their training and practice focus. Many also specialize in managing specific areas like hepatology (liver disease) or IBD.
