Frequently Asked Questions: Gastroenterology

When should I see a Gastroenterologist?
Consult a Gastroenterologist for persistent heartburn or acid reflux not responding to antacids, chronic abdominal pain, blood in stool, unexplained weight loss, persistent diarrhea or constipation, difficulty swallowing, jaundice (yellowing of skin or eyes), or abnormal liver function tests.
What is the difference between acidity and GERD?
Occasional acidity after spicy or heavy meals is normal. GERD (Gastroesophageal Reflux Disease) is a chronic condition where stomach acid frequently flows back into the esophagus, causing heartburn 2 or more times per week, regurgitation, chest pain, or difficulty swallowing. Untreated GERD can damage the esophageal lining.
When should I get a colonoscopy?
Screening colonoscopy is recommended starting at age 45 for average-risk individuals. If you have a family history of colon cancer, screening should begin 10 years before the age your relative was diagnosed or at age 40, whichever is earlier. Symptoms like rectal bleeding, change in bowel habits, or unexplained anemia warrant earlier evaluation.
Can fatty liver disease be reversed?
Yes, non-alcoholic fatty liver disease (NAFLD) in its early stages can be reversed through lifestyle changes: weight loss of 7-10% body weight, regular exercise, a Mediterranean-style diet, avoiding sugar and refined carbs, and limiting alcohol. If left untreated, it can progress to NASH, fibrosis, cirrhosis, and liver failure.
