Heartburn that keeps coming back, bloating that changes how you plan your day, or a test result that raises new questions can leave you wondering who should look after your digestive health. Searching for a gastroenterologist in Katy or Houston often turns up a long list of names and very little guidance. Choosing well starts with knowing what matters. Here is how you can weigh training, services, locations and fit before you book.
What Does a Gastroenterologist Do for Your Digestive Health?
A gastroenterologist is a physician who focuses on the digestive system, which includes the esophagus, stomach, intestines, liver, pancreas and gallbladder.1 Some digestive conditions are short lived, while others are chronic and benefit from steady follow up over months or years.1
Your primary care doctor may suggest a referral when symptoms persist or do not improve with first steps. For example, people with reflux are sometimes referred to a gastroenterologist when symptoms do not settle with medicines and lifestyle changes, or when a complication is suspected.2 Common reasons to seek this kind of care include gastroesophageal reflux disease, irritable bowel syndrome, ongoing abdominal pain, changes in bowel habits and liver concerns such as fatty liver disease.
Training and Credentials Worth Checking in Katy and Houston
Credentials tell you how a physician was trained and whether that training has been independently reviewed. Gastroenterologists usually complete internal medicine residency and then a separate gastroenterology fellowship. The American Board of Internal Medicine offers board certification in gastroenterology, and you can ask any practice whether its physicians hold it.3
When you see us, your care is guided by a board certified gastroenterologist who trained in internal medicine and gastroenterology at the University of Texas Medical Branch in Galveston and has served the Katy community for more than 21 years. You can review the background of each clinician on our team of gastroenterologists, nurse practitioners, physician assistants and a functional dietitian before your first visit.
Does the Practice Treat the Conditions You Are Dealing With?
Not every gastroenterology office has the same focus. Before you book, look at whether the practice regularly cares for the problem that brings you in. Our care covers a wide range of digestive concerns, including celiac disease, Crohn's disease, small intestinal bacterial overgrowth, gastroparesis, gastritis and hepatitis C.
It also helps to know whether diagnostic procedures are part of the care you receive. An upper GI endoscopy lets a physician view the lining of the esophagus, stomach and duodenum,4 while a colonoscopy examines the colon. Screening guidance from the U.S. Preventive Services Task Force now recommends that adults at average risk begin colorectal cancer screening at age 45.5 Ask how a practice approaches screening and whether it fits your history.
Is an Integrative Approach Right for You?
Some people want care that looks beyond a single prescription. Our integrative approach to gastroenterology combines conventional treatment with nutrition guidance and attention to lifestyle, with the aim of addressing the root cause of your symptoms.
Practical Questions: Locations, Insurance and Your First Visit
Convenience matters when you may need several appointments, tests or procedures. Our offices are at 25230 Kingsland Blvd, Suite 102, in Katy and 1240 Blalock Rd, Suite 210, in Houston, so you can choose the location that suits your commute. You can find directions on our Katy and Houston practice locations page.
Before your first visit, check whether your plan is accepted and whether you need a referral. Our insurance information page is a good starting point, and it helps to bring your ID, insurance card, a list of medicines and any earlier reports or imaging. Taking a few minutes to prepare for your visit can make that first conversation more productive.
Signs a Specialist Is a Good Fit

Frequently Asked Questions
How do I find a good gastroenterologist in Katy, TX?
Start by confirming training, board certification and experience with your specific condition. Then consider practical factors such as office location, insurance and how easily you can reach the team with questions. Our Katy office on Kingsland Blvd and our Houston office on Blalock Rd give you two options in the area.
Do I need a referral to see a gastroenterologist?
It depends on your insurance plan. Some plans require a referral from your primary care doctor, while others do not, so it is wise to check with your insurer and our office before you book.
When should I see a gastroenterologist instead of my primary care doctor?
You may benefit from a gastroenterologist when digestive symptoms persist, return often or do not improve with initial treatment. Ongoing heartburn, trouble swallowing, unexplained weight loss and blood in the stool are reasons to seek prompt evaluation.
What is the difference between a gastroenterologist and a general surgeon?
A gastroenterologist diagnoses and treats digestive conditions medically and performs procedures such as endoscopy and colonoscopy. A general surgeon performs operations, and the two often work together when surgery is needed.
What should I bring to my first gastroenterology appointment?
Bring a photo ID, your insurance card, a current list of medicines and any earlier records, reports or imaging. A referral letter, if your plan requires one, and completed patient forms can also help your visit go smoothly.
