Dr. Jeremy Theal diagnoses and treats a wide range of digestive system disorders, including:

Functional Gastrointestinal & Motility Disorders

• 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).
• 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.
• Pelvic Floor Dysfunction & Anorectal Disorders (e.g., Dyssynergic Defecation): Inability to correctly relax and coordinate pelvic floor muscles to facilitate a normal bowel movement, often requiring specialized testing like anorectal manometry and biofeedback therapy.

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.
• 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.
• 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.

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.
• 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.
• Hiatal Hernia & Paraesophageal Hernia: Condition where part of the stomach pushes upward through an opening (hiatus) in the diaphragm into the chest, potentially contributing to GERD and other symptoms.

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

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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. Theal for care relevant to your specific condition.

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

Medically necessary consultations with a licensed Gastroenterologist like Dr. Theal, 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. Theal'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. Theal, 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. Theal 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.

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

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

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

Yes, a Gastroenterologist like Dr. Theal 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.

How does a Gastroenterologist like Dr. Theal approach the management of Inflammatory Bowel Disease (IBD)?

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Theal 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 integral parts of comprehensive IBD care.

Are there significant risks associated with procedures like gastroscopy or colonoscopy?

Gastroscopy (upper endoscopy) and colonoscopy are generally very safe procedures, especially when performed by an experienced Gastroenterologist like Dr. Theal. Complications are uncommon. Potential risks can include bleeding, particularly if polyps are removed or biopsies are taken; perforation (a tear in the wall of the digestive tract); infection (rare); or adverse reactions to the sedative medication used. Before your procedure, Dr. Theal will thoroughly discuss the specific potential risks and benefits based on your individual health and the reason for the procedure, allowing you to make an informed decision.
