Our mission
Our mission is to honor God through serving humanity.
Our goal is to provide you with services that nurture you physically, mentally and spiritually, thereby improving the standards of healthcare in the community in which we serve.
What does a gastroenterologist treat? Your whole digestive system, from esophagus to colon, plus the liver.
Here are the conditions patients most often come to Delta Gastro for.
Colon cancer screening
Colonoscopies in our on-site endoscopy center, starting at 45.
Fatty liver disease
Painless screening for MASLD before it damages your liver.
Medical weight loss
GLP-1 medication, Orbera® balloon, and body composition tracking.
Heartburn and GERD
Find the cause of reflux that keeps coming back.
Colon cancer screening
When should you get a colonoscopy? At age 45 for most adults.
Adults at average risk should begin colorectal cancer screening at 45. You may need to start earlier with a family history of colorectal cancer or a personal history of polyps, ulcerative colitis, or Crohn's disease.
Colorectal cancer is the second leading cause of cancer death for men and women combined in the United States. Call us if you notice:
- Blood in or on your stool
- Stomach pain that won't go away
- Weight loss you can't explain
- Ongoing constipation or diarrhea
These can have other causes, but they should always be checked. Learn more at Fight Colorectal Cancer.
Does a colonoscopy hurt? Most patients are comfortable throughout.
Patients are sedated during a colonoscopy at Delta Gastroenterology. With today's sedation and equipment, most patients are comfortable and many don't remember the procedure.
A clean colon lets the doctor see clearly, so preparation starts the day before. Following your prep instructions is what makes the exam accurate.
Screening now starts at 45, and earlier for people with a family history of colon cancer or a personal history of polyps, ulcerative colitis, Crohn's disease, or uterine or breast cancer.
Liver health
Do you have fatty liver disease? About 1 in 3 adults does, and most don't know it.
Fatty liver disease, now called MASLD, usually causes no symptoms until the liver is seriously damaged. A simple, painless screening can find it early, when it can still be reversed.
MASLD is the new name for NAFLD. Its inflamed form, MASH (formerly NASH), can lead to scarring, cirrhosis, liver cancer, and transplant, and MASLD raises heart disease risk. Get screened if you have:
- Diabetes or prediabetes
- High blood pressure
- High cholesterol
- Obesity or extra weight
Watch: what fatty liver disease is and why early screening matters.
Obesity and weight loss management
Can GLP-1 weight-loss medications cost you muscle? Yes, unless you plan for it.
Wegovy (semaglutide) and Zepbound (tirzepatide) cause loss of both fat and muscle. Enough protein, regular activity, and body composition tracking help you keep the muscle.
These medications slow stomach emptying and reduce hunger signals, which can also lower blood sugar, liver fat, blood pressure, and LDL. Common side effects include nausea, vomiting, diarrhea, constipation, dry mouth, and worse acid reflux.
- Eat lean meat, fish, eggs, and cheese for protein, plus plenty of fiber and vegetables.
- Limit sugary drinks, pastries, highly processed food, and alcohol.
- Body composition assessment: see what's really in your body.
- Orbera®: a temporary, non-surgical gastric balloon that teaches portion control.
Why choose Delta Gastro? Specialist care, close to home.
