Dr. Jennifer Williams diagnoses and treats a wide range of digestive system disorders, including:

Functional Gastrointestinal & Motility Disorders

• 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.
• 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).

Liver, Gallbladder, Bile Duct & Pancreatic Disorders

• 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.
• Gallstone Disease (Cholelithiasis), Cholecystitis & Choledocholithiasis: Formation of hardened deposits (gallstones) in the gallbladder. Cholecystitis is gallbladder inflammation. Choledocholithiasis refers to gallstones in the common bile duct.
• Pancreatic Cysts, Tumors & Pancreatic Insufficiency (Evaluation & Co-management): Evaluation of fluid-filled sacs (cysts) or growths (tumors) on or in the pancreas, and management of exocrine pancreatic insufficiency (EPI) where the pancreas doesn't produce enough digestive enzymes.

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.
• 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).

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

• 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.
• 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.
• 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.
• 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.
• 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).
• 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.

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

Are consultations and procedures like endoscopies with Dr. Williams, a Gastroenterologist, covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Williams, 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. Williams'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. Williams, 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. Williams 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 are common reasons someone would be referred to a Gastroenterologist like Dr. Williams?

Referral to a Gastroenterologist like Dr. Williams 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.

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

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. Williams or the anesthesia provider beforehand. Because of the sedation, you will need to have someone accompany you to drive you home after the procedure.
