A Gastroenterologist specializes in diagnosing and treating disorders affecting the digestive system, including the esophagus, stomach, intestines, liver, pancreas, and gallbladder. You should seek consultation if you experience persistent acidity, abdominal pain, bloating, difficulty swallowing, chronic constipation or diarrhea, blood in the stool, unexplained weight loss, jaundice, or abnormal liver function tests. Early evaluation helps identify underlying conditions promptly, enabling timely treatment, preventing complications, and promoting better long-term digestive and liver health.

Dr. Khushboo Madaan provides comprehensive care for a wide range of gastrointestinal and liver disorders. These include GERD, gastric and duodenal ulcers, hepatitis, liver cirrhosis, hepatocellular carcinoma (HCC), pancreatitis, choledocholithiasis, inflammatory bowel disease (Crohn's disease and ulcerative colitis), irritable bowel syndrome (IBS), GI infections, gastrointestinal bleeding, esophageal strictures, corrosive ingestion injuries, and gastrointestinal cancers. She also offers advanced hepatobiliary care and endoscopic management for complex digestive disorders.

Upper GI endoscopy is a minimally invasive procedure that uses a flexible camera-equipped endoscope to examine the esophagus, stomach, and upper small intestine. It is commonly recommended for persistent acidity, difficulty swallowing, unexplained abdominal pain, nausea, vomiting, GI bleeding, or suspected ulcers. The procedure helps diagnose inflammation, infections, tumors, and bleeding while allowing biopsies and therapeutic interventions when required, making it an essential tool for accurate gastrointestinal diagnosis.

Endoscopic Retrograde Cholangiopancreatography (ERCP) is an advanced endoscopic procedure used to diagnose and treat disorders affecting the bile ducts and pancreatic ducts. It is commonly performed to remove bile duct stones, relieve obstructions, treat strictures, manage leaks, and place or remove stents. ERCP combines endoscopy with fluoroscopic imaging, enabling both diagnosis and treatment during the same procedure, often eliminating the need for more invasive surgical interventions.

Endoscopic Ultrasound (EUS) combines endoscopy with high-resolution ultrasound imaging to evaluate the digestive tract and nearby organs, including the pancreas, liver, gallbladder, and lymph nodes. It plays an important role in diagnosing gastrointestinal cancers, pancreatic disorders, submucosal lesions, and bile duct abnormalities. EUS also enables minimally invasive tissue sampling through fine-needle aspiration or biopsy, helping establish an accurate diagnosis and guide personalized treatment planning.

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent abdominal pain associated with changes in bowel habits, including constipation, diarrhea, or both. Although IBS does not permanently damage the intestines, it can significantly affect daily life. Diagnosis is based on clinical evaluation after excluding serious conditions. Treatment typically involves dietary modifications, stress management, lifestyle changes, and medications tailored to the patient's specific symptoms and individual needs.

Although IBS and IBD may share similar symptoms, they are distinct conditions. IBS is a functional disorder without intestinal inflammation, whereas IBD includes chronic inflammatory diseases such as Crohn's disease and ulcerative colitis that can damage the digestive tract. IBD often requires long-term medical therapy and regular monitoring. Accurate diagnosis through clinical assessment, laboratory investigations, endoscopy, and imaging is essential to ensure appropriate treatment and prevent complications.

Liver function tests and FibroScan are recommended for individuals with fatty liver disease, hepatitis, abnormal liver enzymes, excessive alcohol consumption, obesity, diabetes, or a family history of liver disease. FibroScan is a non-invasive technique that measures liver stiffness and helps assess fibrosis without requiring a biopsy. Early evaluation allows timely intervention, slows disease progression, and helps prevent serious complications such as cirrhosis and liver failure.

Persistent digestive symptoms should always be evaluated by a specialist. Warning signs include unexplained weight loss, difficulty swallowing, persistent vomiting, severe abdominal pain, blood in vomit or stool, black stools, jaundice, persistent diarrhea, prolonged constipation, anemia, or unexplained fatigue. These symptoms may indicate serious gastrointestinal or liver conditions requiring prompt diagnosis. Early medical attention significantly improves treatment success and reduces the risk of long-term complications.

Early detection of gastrointestinal cancers relies on recognizing warning symptoms, regular health evaluations, and timely screening in high-risk individuals. Procedures such as upper GI endoscopy, colonoscopy, Endoscopic Ultrasound (EUS), and appropriate imaging studies help identify precancerous lesions and early-stage cancers. Individuals with a family history, chronic inflammatory conditions, or persistent digestive symptoms should undergo specialist evaluation, as early diagnosis substantially improves treatment options and long-term survival.

Maintaining digestive and liver health requires a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while limiting processed foods, alcohol, and excessive fatty meals. Regular physical activity, maintaining a healthy body weight, adequate hydration, avoiding tobacco, practicing good food hygiene, and managing stress also contribute to digestive wellness. Routine medical check-ups and early evaluation of persistent gastrointestinal symptoms further help prevent disease progression and promote long-term health.
