Dr. Abdel Shaheen diagnoses and treats a wide range of digestive system disorders, including:

Inflammatory Bowel Disease (IBD) Focus

• 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.
• 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.

Esophageal, Stomach & Upper GI Disorders

• 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.
• 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.
• 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).

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.
• 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.
• Chronic Viral Hepatitis (Hepatitis B, C, D): Long-term viral infections that cause inflammation and damage to the liver, potentially leading to cirrhosis, liver failure, or liver cancer if untreated.

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

• 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.
• 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.
• 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.
• 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.
• 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.
• Screening & Prevention Strategies for Gastrointestinal Cancers: Risk assessment and counseling on screening for colorectal cancer, esophageal cancer (in Barrett's esophagus), gastric cancer, and liver cancer (in cirrhosis), including FIT testing and colonoscopy recommendations.

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

Medically necessary consultations with a licensed Gastroenterologist like Dr. Shaheen, 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. Shaheen'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. Shaheen, 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. Shaheen 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 some common procedures a Gastroenterologist like Dr. Shaheen typically performs?

Gastroenterologists like Dr. Shaheen 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, he 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.

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

The management of IBD (Crohn's disease and ulcerative colitis) by a Gastroenterologist like Dr. Shaheen 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.
