Gastroenterology + Digestive Health

Your gastrointestinal (GI) system breaks down the nutrients in food and liquid and helps your body use those nutrients for energy, growth and healing. The system covers a lot of ground—from the mouth, throat and esophagus to the stomach, intestines, rectum and anus.

Gastrointestinal problems can have a big impact on your quality of life by affecting your diet and causing discomfort. Many people don't seek treatment for their gastrointestinal conditions because symptoms like gas and bathroom habits leave them feeling self-conscious. Rest assured, you’re far from alone and don’t have to continue living this way.

Digestive disorders affect 60–70 million Americans. Our specialists are here to put you at ease, with comfort-focused care for any gastrointestinal or digestive condition you might be living with.

We're here to help you manage your GI symptoms and improve your quality of life. Our personalized services are designed to help you manage a variety of GI conditions.

Eosinophilic esophagitis (EoE)

Eosinophilic esophagitis (EoE) occurs when white blood cells called eosinophils create inflammation in the esophagus. Food allergies can trigger EoE. It's important to know that a food allergy associated with EoE is quite different from food allergies you might be familiar with.

Food related diseases

Food related diseases can trigger a variety of symptoms, like belching, gas, irregular bowel movements and difficulty swallowing. Once we’ve identified what may be triggering you, we'll work together to create a dietary plan that's filled with foods you’ll love and the nutrients you need.

Gastroenterology + nutrition

Our gastroenterology nutrition clinic can assist if your condition makes it challenging to obtain nutrients. We treat a variety of gastrointestinal conditions and manage the nutritional complications associated with these disorders. When you have difficulty retaining nutrients from your food, we provide nutritional support strategies.

GERD, heartburn + esophageal motility

Esophageal motility refers to the muscle movement of your esophagus. Conditions like gastroesophageal reflux disease (GERD) and heartburn affect how food travels from your mouth, down the esophagus and into your stomach. It's because the muscles in the esophagus don't work like they should.

To determine the cause of your symptoms, our team may recommend an esophageal motility study to check the esophagus for abnormal movements.

Inflammatory bowel disease

Inflammatory bowel disease can take a serious toll on your gastrointestinal tract from the moment food enters the body to when it leaves. The two most common inflammatory bowel diseases are Crohn's disease and ulcerative colitis. They’re similar in many ways, and even overlap in symptoms.

Liver disease

The liver is responsible for more than 500 bodily functions, like filtering, cleaning and re-circulating all blood through the body and metabolizing medications. Liver disease refers to diseases that weaken or harm the liver over time, like cirrhosis.

Paraesophageal hernia

A paraesophageal hernia is a more uncommon type of hiatal hernia where a large part of the stomach slips through the esophageal hiatus and into the esophagus. Typically, treatment involves a minimally invasive surgery, and most people are able to return to their normal activity within a week.

Small bowel disease

There's nothing small about the small bowel (also known as the small intestine) — stretching about the length of a giraffe. Small bowel disease impacts the body's ability to absorb nutrients as food passes from the stomach, through the small intestine and to the large intestine. The most common types of small bowel disease are Crohn's disease and celiac disease.

It’s important to talk to your doctor when you experience the following symptoms that could be linked to a gastrointestinal disorder:

  • Abdominal pain
  • Bloody stool
  • Difficulty swallowing
  • Esophageal pain
  • Excessive heartburn
  • Gas
  • Loss of appetite
  • Rectal bleeding
  • Significant changes in bowel habits
  • Unintended weight loss


If your symptoms line up with a gastrointestinal condition, we’ll work with you to pinpoint what’s ailing you. Some of the tests we may perform include:

24-hour PH impedance monitoring

We use a 24-hour PH impedance monitoring test to measure the amount of acid reflux or “back up” from the stomach into the esophagus. Here’s what to expect if your doctor orders a 24-hour PH impedance monitoring test:

  • We’ll thread a thin, wire-sized catheter through your nose or mouth and position it at the base of your esophagus. This catheter will stay in place for 24 hours.
  • You can carry on with your daily activities while the catheter monitors and tracks your meals, sleep and symptoms. 
  • After 24-hours, we’ll remove the catheter and analyze the data. 
Anorectal manometry

An anorectal manometry is a non-invasive test used to examine how the anal and rectal muscles function, like their:

  • Ability to have a bowel movement
  • Ability to squeeze and hold a volume of fluid
  • Anal muscle strength
  • Nerve supply to the anal muscle
  • Rectal sensation

This test involves inserting a catheter about the size of a pencil approximately 6 inches into the rectum. Be sure to talk with your doctor about any medications you’re currently taking before getting an anorectal manometry.

Capsule endoscopy

A capsule endoscopy is a procedure we use to better understand the insides of your digestive system. The test works by swallowing a PillCam that will snap photos of your insides as it moves through your intestines. These images get transmitted to the sensor belt for your doctor to view in real time.


A colonoscopy is an endoscopic exam where a doctor inserts a flexible endoscope into the large intestine to detect any warning signs — ulcers, colon polyps, tumors and areas of inflammation or bleeding — for colon cancer and other diseases.

A colonoscopy is the most tried-and-true way for preventing colon cancer. This is because we can remove any suspicious polyps on the spot.

Endoscopic retrograde cholangiopancreatography (ERCP)

An ERCP helps us examine your bile and pancreatic ducts. It combines using an endoscope (a flexible instrument with a light and camera on the end) and X-rays to get a clear picture of your insides.

Esophageal motility study (EMS)

An esophageal motility study (EMS) is used to check the esophagus for abnormal movements. It’s a helpful test we order for people living with a combination of the following symptoms:

  • Chest pain
  • Coughing
  • Difficulty swallowing
  • Heartburn that’s not responding to acid medications 
  • Hoarseness
  • Sore throat
  • Wheezing

You can rest assured that this is a fairly quick and very safe procedure. We kickoff the study by numbing the nose. This is to help you feel more comfortable as we pass a catheter roughly the size of a thick spaghetti strand through one nostril, down the back of the throat and into the esophagus. We’ll ask you to swallow as we thread the catheter into place.

The catheter is lined with tiny sensors that measure the squeeze of the upper esophageal sphincter (UES) and lower esophageal sphincter (LES). These sphincters are like automatic doors — they remain closed until they sense food or liquid moving toward them, then relax and open for the food and liquid to pass through the esophagus (UES) and into the stomach (LES).

To evaluate the squeeze of your UES and LES, you’ll be asked to swallow about one teaspoon of water at a time so your doctor can record and analyze the muscle movements.

Flexible sigmoidoscopy

A flexible sigmoidoscopy is a special exam used to evaluate the S-shaped part of the colon attached to the rectum, known as the sigmoid colon. It involves inserting a lighted tube into the rectum to then get a better look of the sigmoid colon.

While sedatives aren’t needed for this exam, you can request a sedative to make you feel more comfortable. In that case, you’ll need someone 18 years or older to get you home safely the day of your exam.

Upper GI endoscopy

An upper gastrointestinal (GI) endoscopy is a type of exam doctors use to evaluate 3 main parts of your upper GI tract:

  • Esophagus 
  • Stomach
  • Duodenum (first part of the small intestine)

The endoscope has a light and camera attached to the end of it, allowing your doctor to examine your body in real time.

It is possible that more tests may be required and they could include:

  • Barium X-ray
  • Blood tests
  • Breath test
  • CT scan
  • Esophagogastroduodenoscopy (EGD)
  • Manometry
  • MRI
  • pH monitoring
  • Stool analysis
  • Transient elastography
  • Ultrasound
  • X-ray


Once we’ve diagnosed your gastrointestinal condition, we’ll design a treatment plan around your unique healthcare needs. We may recommend treatments ranging from lifestyle changes to medication to surgery.

Some of our common treatment options that can help you feel like yourself again include:
