Dr. Allen Whey Khye Lim

Dr. Allen Lim diagnoses and treats a wide range of digestive system disorders, including:

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.
• Dysphagia (Difficulty Swallowing) & Odynophagia (Painful Swallowing): Symptoms requiring investigation to determine underlying causes, which can range from structural abnormalities and motility disorders to inflammatory conditions or tumors.

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.
• 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.

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.
• 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.
• 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.

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

• Upper Endoscopy (EGD - Esophagogastroduodenoscopy) with Biopsy & Interventions: Diagnostic and therapeutic procedure to examine the esophagus, stomach, and duodenum using a flexible tube with a camera. Allows for targeted biopsies, polyp removal (polypectomy), dilation of strictures, control of bleeding (hemostasis), and foreign body removal.
• 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.
• 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.
• Management of Common & Chronic Digestive Symptoms: Investigating and treating common but potentially disruptive digestive symptoms such as heartburn, acid reflux, bloating, abdominal pain, cramping, excessive gas, constipation, diarrhea, difficulty swallowing (dysphagia), and unexplained weight loss.
• 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).
• Management of Functional Dyspepsia & Functional Abdominal Pain Syndrome: Diagnosis and management of chronic upper abdominal pain or discomfort (dyspepsia) or generalized abdominal pain without an identifiable structural cause, often involving lifestyle, dietary, and neuromodulator therapies.
• 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.

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

Are consultations and procedures like endoscopies with Dr. Lim, a Gastroenterologist, covered by Alberta Health Care Insurance Plan (AHCIP) in AB?

Medically necessary consultations with a licensed Gastroenterologist like Dr. Lim, 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 Alberta Health Care Insurance Plan (AHCIP) in AB 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. Lim's office, the hospital/clinic's financial services, or Alberta Health Care Insurance Plan (AHCIP) beforehand.

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

Referral to a Gastroenterologist like Dr. Lim 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.

What's the difference between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)? Can Dr. Lim diagnose and treat both?

Yes, a Gastroenterologist like Dr. Lim 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.
