Dr. Hoi Yau diagnoses and treats a wide range of digestive system disorders, including:

Esophageal, Stomach & Upper GI Disorders

• 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.
• Peptic Ulcer Disease (Gastric, Duodenal, H. pylori-related, NSAID-induced): Open sores that develop on the inside lining of the stomach (gastric ulcer) and the upper portion of the small intestine (duodenal ulcer), commonly caused by H. pylori infection or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Inflammatory Bowel Disease (IBD) Focus

• 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.
• 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.

Small & Large Intestine (Colorectal) Disorders

• 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.
• Gastrointestinal Bleeding (Obscure & Overt): Bleeding anywhere along the digestive tract, which can be visible (overt) or hidden (occult/obscure), requiring investigation to identify and treat the source.
• Ischemic Colitis: Inflammation and injury of the large intestine that results from inadequate blood flow.

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

• Irritable Bowel Syndrome (IBS) Comprehensive Diagnosis & Management (including subtypes IBS-D, IBS-C, IBS-M): Multifaceted approach to managing IBS symptoms (abdominal pain, bloating, diarrhea, constipation, mixed pattern) including thorough exclusion of other conditions, dietary modifications (e.g., low FODMAP diet), lifestyle changes, stress management, and targeted medications.
• 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.
• 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.
• Colonoscopy (Screening, Diagnostic, Surveillance) & Polypectomy: Comprehensive examination of the entire colon (large intestine) using a colonoscope to detect and remove precancerous polyps, screen for and diagnose colorectal cancer, evaluate symptoms, and diagnose other colonic conditions like colitis or diverticular disease.
• Diagnosis & Management of Small Intestinal Bacterial Overgrowth (SIBO) & Intestinal Methanogen Overgrowth (IMO): Utilizing glucose or lactulose breath tests for diagnosis and providing targeted antibiotic/antimicrobial therapy, prokinetics, and dietary advice for SIBO and IMO.
• 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.
• 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. Yau, a Gastroenterologist, covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Yau, 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 Medical Services Plan (MSP) in BC 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. Yau's office, the hospital/clinic's financial services, or Medical Services Plan (MSP) beforehand.

Do I need a referral from my family doctor to see Dr. Yau, 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. Yau 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.

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. Yau'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 common reasons someone would be referred to a Gastroenterologist like Dr. Yau?

Referral to a Gastroenterologist like Dr. Yau is common for various reasons, including: persistent heartburn or acid reflux (GERD); difficulty or pain when swallowing; unexplained abdominal pain or bloating; chronic nausea or vomiting; significant changes in bowel habits (e.g., chronic diarrhea, severe constipation); blood in the stool or rectal bleeding; iron deficiency anemia with no obvious cause; suspected or diagnosed Inflammatory Bowel Disease (Crohn's disease, ulcerative colitis); Irritable Bowel Syndrome (IBS) not responding to initial management; celiac disease; abnormal liver function tests or suspected liver disease (like hepatitis or fatty liver); pancreatitis; or for screening and surveillance colonoscopies to prevent colorectal cancer, especially if there's a family history or personal history of polyps.

How does Dr. Yau approach treating functional GI disorders like IBS or functional dyspepsia?

Treating functional GI disorders like Irritable Bowel Syndrome (IBS) or functional dyspepsia often involves a multi-faceted approach tailored by Dr. Yau to your specific symptoms and triggers. Since these conditions don't have a structural cause seen on tests, management focuses on symptom relief and improving quality of life. This may include dietary modifications (like identifying trigger foods or trying a low FODMAP diet for IBS), lifestyle adjustments (stress management, regular exercise), fiber supplements, over-the-counter remedies, and prescription medications. Medications can target specific symptoms like pain (antispasmodics), diarrhea (anti-diarrheals), constipation (laxatives), or abnormal gut-brain interaction (neuromodulators in low doses). He will work with you to find the most effective combination of strategies.

Will I be asleep for my endoscopy or colonoscopy with Dr. Yau?

For most endoscopic procedures like upper endoscopy (gastroscopy) and colonoscopy, patients are typically given sedation to help them relax and be comfortable. This is often called 'conscious sedation' or 'moderate sedation,' meaning you'll be drowsy and may not remember much of the procedure, but you won't be under general anesthesia (completely unconscious with a breathing tube). The specific type and level of sedation can vary and will be discussed with you by Dr. Yau or the anesthesia provider beforehand. Because of the sedation, you will need to have someone accompany you to drive you home after the procedure.
