About the Department

The Department of Medical Gastroenterology & Hepatology at Charak Hospital, Lucknow offers comprehensive diagnosis, medical management, and endoscopic treatment of all digestive system and liver disorders. Our team of DM-qualified gastroenterologists manages conditions ranging from common problems like acidity, IBS, and gallstone disease to complex hepatological emergencies including liver cirrhosis, variceal bleeding, and liver failure.

Hepatology — the sub-speciality within our department — focuses specifically on the liver, bile ducts, gallbladder, and pancreas. It encompasses the full spectrum of liver disease from non-alcoholic fatty liver (NAFLD) and viral hepatitis to cirrhosis, portal hypertension, and liver cancer. Our hepatologists work closely with the Surgical Gastroenterology & HPB team for patients requiring procedural or surgical intervention.

Diagnostic & Therapeutic Procedures

Camera examination of the oesophagus, stomach, and duodenum. Used to diagnose GERD, ulcers, gastritis, polyps, and Barrett's oesophagus. Biopsy sampling, polypectomy, and foreign body removal can be performed in the same session. Performed under sedation — comfortable and quick (10–15 minutes).
Examination of the large intestine (colon and rectum). Used to detect colorectal cancer, polyps, IBD (Crohn's, Ulcerative Colitis), diverticular disease, and the cause of rectal bleeding. Polyps can be removed during the same procedure (polypectomy). Recommended for people over 45 or those with GI symptoms.
A combined endoscopic and X-ray procedure to diagnose and treat conditions of the bile ducts and pancreatic duct — including common bile duct stones, strictures, and obstructive jaundice. ERCP can remove stones, place stents to relieve blockages, and take tissue biopsies. It eliminates the need for open surgery in many biliary stone cases.
High-resolution ultrasound imaging from inside the GI tract. Used for staging oesophageal, gastric, and pancreatic cancers; evaluating submucosal lesions; assessing bile duct stones; and performing EUS-guided fine-needle biopsy (FNB) of pancreatic and mediastinal masses. Provides superior resolution compared to external ultrasound or CT for these deep structures.
A painless, non-invasive 5-minute test that measures liver stiffness (fibrosis) and fat content (CAP — Controlled Attenuation Parameter). Used to grade liver damage in Hepatitis B, Hepatitis C, NAFLD, and cirrhosis — without needle biopsy. Ideal for monitoring disease progression and response to antiviral treatment. Results are available immediately.
Life-saving endoscopic procedure to treat and prevent variceal bleeding in liver cirrhosis patients. Rubber bands are placed on dilated veins (varices) in the oesophagus to cut off blood supply and prevent rupture. Performed as emergency treatment for active variceal haemorrhage, and as prophylactic banding to reduce rebleeding risk. Available 24/7 at our endoscopy suite.
Liver Biopsy: Ultrasound-guided needle sampling of liver tissue for definitive diagnosis of liver disease stage and aetiology — used when FibroScan/blood tests are inconclusive.

Paracentesis: Drainage of fluid (ascites) accumulated in the abdomen due to liver cirrhosis or portal hypertension. Provides rapid symptom relief and fluid analysis for diagnostic workup.

Frequently Asked Questions

The Gastroenterology Department, Charak Hospital, Lucknow, specializes in the diagnosis and treatment of diseases related to the digestive system. This includes conditions affecting the esophagus, stomach, small intestine, large intestine (colon), and accessory organs such as the liver, gallbladder, and pancreas. Services typically include upper endoscopy, colonoscopy, treatment for acid reflux, management of inflammatory bowel disease (IBD), liver disease, and pancreatic disorders, among others.

If you experience persistent symptoms such as abdominal pain, bloating, difficulty swallowing, heartburn, acid reflux, unexplained weight loss, persistent diarrhea, or blood in your stool, it may be advisable to consult a gastroenterologist. These symptoms could indicate a variety of conditions that require medical attention.

Diagnosis of gastrointestinal disorders often involves a combination of methods including physical examination, patient history review, blood tests, imaging studies like ultrasound or CT scans, and endoscopic procedures. Endoscopes are medical devices used to visualize the inside of the digestive tract, helping doctors identify ulcers, tumors, inflammation, or other abnormalities.

The treatment options for gastrointestinal diseases depend on the specific condition. They can range from lifestyle changes and dietary modifications to medications, endoscopic interventions, and sometimes surgery. For instance, acid reflux might be managed with antacids or proton pump inhibitors, while severe cases of IBD might require biologic therapies or surgical interventions to remove damaged sections of the bowel.

Hepatology is the branch of medicine that focuses on the study, prevention, diagnosis, and treatment of diseases affecting the liver, gallbladder, biliary tree, and pancreas. The Hepatology Department specializes in managing conditions such as hepatitis (caused by viruses A, B, C, D, and E), cirrhosis, liver cancer, fatty liver disease, and disorders of the gallbladder and bile ducts.

Symptoms that may suggest the need for a consultation with a hepatologist include persistent abdominal pain, especially in the upper right quadrant, jaundice (yellowing of the skin and eyes), fatigue, unexplained weight loss, dark urine, pale stools, and swelling in the legs or abdomen. These symptoms can be indicative of liver disease and should be evaluated by a specialist.

Diagnosis often begins with a thorough medical history and physical examination. Blood tests are commonly used to assess liver function and to screen for viral hepatitis. Imaging studies such as ultrasound, CT scans, or MRI can help visualize the liver and surrounding structures. Biopsies, where a small sample of liver tissue is taken for analysis, can provide definitive information about the liver's condition.

Treatment options vary widely depending on the specific disease. For viral hepatitis, antiviral medications might be prescribed. Lifestyle changes, such as dietary modifications and abstinence from alcohol, are often recommended for patients with fatty liver disease. In cases of advanced liver disease, such as liver failure or certain types of liver cancer, liver transplant may be considered. The Hepatology Department collaborates with other specialists to ensure a comprehensive approach to patient care.
