Months of Googling. Years of antacids.
These symptoms have names. And there are specialists trained specifically to investigate them — click any to see what they actually look for.
Heartburn & Acid Reflux
Months of antacids. Still there every morning.
That burning sensation after meals isn't just discomfort — persistent acid reflux can signal GERD, Barrett's esophagus, or hiatal hernia.
What a GI doctor investigates:
When to see a specialist: Symptoms more than twice a week, or if antacids aren't providing relief.
Bloating & Gas
Uncomfortable after every single meal.
Chronic bloating can indicate small intestinal bacterial overgrowth (SIBO), food intolerances, or motility disorders that go undetected for years.
What a GI doctor investigates:
When to see a specialist: Bloating that affects daily life, or accompanied by pain, weight loss, or changes in bowel habits.
IBS & Abdominal Pain
Googled your symptoms more times than you can count.
Irritable bowel syndrome affects 10-15% of adults but is often misdiagnosed. A GI specialist can distinguish IBS from IBD, celiac, and other conditions.
What a GI doctor investigates:
When to see a specialist: Pain that disrupts sleep, blood in stool, unintentional weight loss, or symptoms starting after age 50.
Colonoscopy Screening
Your PCP mentioned it. You've been putting it off.
Colorectal cancer is 90% preventable when caught early. Current guidelines recommend screening starting at age 45 for average-risk individuals.
What a GI doctor investigates:
When to see a specialist: Age 45+, family history of colorectal cancer or polyps, or rectal bleeding.
Crohn's & Colitis
Flares that derail your life. Answers that feel out of reach.
Inflammatory bowel disease requires specialist management. Early, targeted treatment can achieve remission and prevent long-term complications.
What a GI doctor investigates:
When to see a specialist: Persistent diarrhea, blood in stool, fever, fatigue, or unintended weight loss.
Pediatric GI
Your child won't eat. You need someone who specializes.
Children's GI issues range from reflux and constipation to celiac and eosinophilic esophagitis. Pediatric GI specialists are trained specifically for young patients.
What a GI doctor investigates:
When to see a specialist: Failure to thrive, persistent vomiting, chronic abdominal pain, or blood in stool in children.

What actually happens during a procedure
The questions you were embarrassed to ask — answered plainly.
Upper Endoscopy (EGD)
A thin, flexible tube with a camera examines your esophagus, stomach, and upper small intestine. Most patients feel nothing and go home within an hour.
Colonoscopy
The gold standard for colorectal cancer screening. The prep is the hardest part — the procedure itself you sleep through. Most people return to normal activity the same day.
Capsule Endoscopy
You swallow a tiny camera pill that photographs your entire small intestine. You go about your day while it works. A GI doctor reviews the images afterward.
Colonoscopy Prep Guide
The complete, plain-language guide to colonoscopy preparation — what to eat, what to avoid, and how to make the prep as comfortable as possible.
