Yes. Every profile is sourced from the federal NPI registry maintained by CMS, and we never sell ranking. Listing order is determined by how complete a practice's verified profile is (services, providers, insurance, hours) — never by payment. Featured and sponsored placements are always clearly labelled as such and never change the directory order, a practice's verification status, or any fact on its profile. A practice can improve its position by claiming its listing and adding information — for free.
Consider a GI specialist for persistent digestive symptoms — frequent heartburn, ongoing abdominal pain, chronic diarrhea or constipation, difficulty swallowing, unexplained weight loss, or rectal bleeding — or when it's time for colon cancer screening. Sudden severe abdominal pain or significant bleeding needs urgent evaluation.
They diagnose and treat conditions of the digestive system — acid reflux/GERD, IBS, inflammatory bowel disease (Crohn's and ulcerative colitis), ulcers, celiac disease, and disorders of the esophagus, stomach, intestines, liver, pancreas, and gallbladder — and perform screenings like colonoscopy.
Current guidelines recommend colorectal cancer screening starting at age 45 for average-risk adults, and earlier if you have a family history or other risk factors. A colonoscopy is one of the most effective screening tools because it can find and remove precancerous polyps.
Often you don't need a referral for a screening colonoscopy if you're 45 or older — many practices offer direct scheduling — while some private plans require a referral and prior authorization for a GI office visit. Original Medicare doesn't require a referral; check your specific plan.
A first visit usually takes 30–60 minutes: the doctor reviews your symptoms, medical and family history, and any treatments you've tried, then examines you and may recommend tests like bloodwork, an endoscopy, or a colonoscopy. Bringing a symptom timeline and medication list helps.
If you have frequent heartburn for six months or more, or it isn't controlled by over-the-counter medication, see a gastroenterologist to evaluate for GERD and rule out other causes. Trouble swallowing, vomiting, or unexplained weight loss with reflux warrants prompt attention.
Irritable bowel syndrome is a common condition causing abdominal pain with changes in bowel habits (diarrhea, constipation, or both). A gastroenterologist can confirm the diagnosis, rule out other conditions, and build a management plan with diet, medication, and lifestyle strategies.
A colonoscopy uses a thin, flexible camera to examine the colon and remove polyps, done under sedation so you're comfortable. Preparation involves a clear-liquid diet and a bowel-cleansing prep the day before; your GI office gives detailed instructions, and you'll need a ride home afterward.
Screening colonoscopies are covered as preventive care by most plans and Medicare, often at no cost when you're due — though if a polyp is found and removed, some plans may apply a cost as it becomes diagnostic. Confirm coverage details with your plan beforehand.
An office visit averages a few hundred dollars self-pay (around $380 on average), with procedures like colonoscopy or endoscopy costing more. Many practices share cash pricing, so ask when scheduling.
Seek urgent or emergency care for severe or sudden abdominal pain, significant rectal bleeding, vomiting blood, black or tarry stools, or abdominal pain with fever — these can signal a serious problem that shouldn't wait for a routine appointment.
A colonoscopy examines the colon (large intestine) from below to screen for cancer and evaluate lower-GI symptoms, while an upper endoscopy examines the esophagus, stomach, and upper intestine from above for issues like reflux, ulcers, or swallowing problems. Both are done with sedation.
For average-risk adults with a normal result, screening is typically repeated every 10 years until about age 75. If polyps are found or you're higher-risk, your gastroenterologist will recommend more frequent follow-up.
Yes — persistent constipation or diarrhea is a common reason to see a GI doctor, who can identify the cause (from IBS to other conditions) and recommend dietary changes, medication, and further testing if needed.
Occasional heartburn is common, but long-standing, frequent reflux can damage the esophagus over time and, in some people, lead to changes that raise cancer risk — which is why ongoing symptoms deserve evaluation. Trouble swallowing, weight loss, or vomiting blood needs prompt care.
Yes — gastroenterologists evaluate and manage many liver, gallbladder, and pancreas conditions, from fatty liver and hepatitis to gallstone-related issues, and coordinate with surgeons when a procedure is required.
