Every Procedure, Handled with Care

From your first screening colonoscopy to advanced diagnostics, we walk you through every step — because understanding what's happening matters as much as the procedure itself.

Colonoscopy

Colonoscopy is the gold standard for colorectal cancer screening. The American Cancer Society recommends screening begin at age 45 for average-risk adults. Our gastroenterologist performs colonoscopies using high-definition equipment for maximum detection accuracy.

Upper Endoscopy (EGD)

Esophagogastroduodenoscopy (EGD) allows your gastroenterologist to examine the lining of your esophagus, stomach, and upper small intestine. This 15-to-20-minute procedure helps diagnose GERD, Barrett's esophagus, ulcers, celiac disease, and more.

Capsule Endoscopy

Capsule endoscopy uses a tiny, swallowable camera to capture thousands of images of your small intestine — an area that traditional endoscopy and colonoscopy cannot fully reach. Ideal for diagnosing obscure GI bleeding, Crohn's disease, and small bowel tumors.

Hemorrhoid Banding

Rubber band ligation is a quick, minimally invasive in-office treatment for internal hemorrhoids. The procedure takes less than a minute and provides lasting relief from bleeding and discomfort without surgery or general anesthesia.

Esophageal Dilation

Esophageal dilation gently stretches a narrowed section of the esophagus to restore comfortable swallowing. It is commonly performed during an upper endoscopy for patients with esophageal strictures caused by GERD, eosinophilic esophagitis, or radiation therapy.

Frequently Asked Questions

Answers to common questions about gastroenterology care, procedures, and what to expect at Texas Gut Health.

You should see a gastroenterologist if you experience persistent digestive symptoms lasting more than two weeks, including chronic heartburn, abdominal pain, bloating, diarrhea, constipation, blood in your stool, or unexplained weight loss. The American College of Gastroenterology also recommends a screening colonoscopy beginning at age 45, or earlier if you have a family history of colorectal cancer. At Texas Gut Health in Sachse, TX, our board-certified gastroenterologist evaluates and treats the full range of digestive conditions.
A colonoscopy is a 30-to-60-minute outpatient procedure performed under sedation. You will not feel pain during the exam. Your gastroenterologist uses a thin, flexible camera to examine the lining of your colon for polyps, inflammation, or other abnormalities. Most patients rest for about 30 minutes afterward and can return to normal activities the next day. The preparation the day before — which involves a clear liquid diet and a bowel-cleansing solution — is the most involved part of the process.
The American Cancer Society recommends that adults at average risk for colorectal cancer begin screening at age 45. If you have a family history of colorectal cancer or polyps, your doctor may recommend starting earlier — typically 10 years before the age your relative was diagnosed, or at age 40, whichever comes first. Preparation typically begins 1 to 3 days before the procedure: you'll follow a low-fiber diet, switch to clear liquids the day before, and drink a prescribed bowel preparation solution. Detailed, personalized prep instructions are provided when you schedule your appointment at Texas Gut Health.
Texas Gut Health accepts most major insurance plans including Aetna, Blue Cross Blue Shield, Cigna, Humana, Medicare, and United Healthcare. We recommend calling our office at (214) 624-6596 to verify your specific plan before your visit. Our team is happy to help you understand your coverage and out-of-pocket costs so there are no surprises.
A gastroenterologist is a physician who has completed an additional 3-year fellowship in gastroenterology after internal medicine residency, with specialized training in diagnosing and treating conditions of the esophagus, stomach, intestines, colon, liver, gallbladder, and pancreas. While your primary care doctor can address general digestive concerns, a gastroenterologist has the advanced training and equipment to perform procedures like colonoscopy, endoscopy, and ERCP, and to manage complex conditions like inflammatory bowel disease, liver disease, and GI cancers.
Yes. Texas Gut Health is currently accepting new patients at our Sachse, TX location.
