Gastroenterology Services at AIMG

What is Gastroenterology?

Gastroenterology is one of the specialty services we provide at Avenel Iselin Medical Group. Our experienced gastroenterology specialists are trained to diagnose and treat problems related to the digestive, or gastrointestinal (GI) tract. These areas include the esophagus (the tube that connects the mouth to the stomach), small intestine, colon, pancreas, gallbladder, bile ducts, and liver. 

AIMG recommends eating a low-fat, low sugar diet rich in vitamins and fiber to aid in a healthy GI system, however, routine checkups and screenings are often also necessary as preventative measures.

When to see a Gastroenterologist

After meeting with one of our family medicine doctors, you may be referred to see a GI specialist if you are experiencing difficulty with:

  • Swallowing 
  • Heartburn
  • Regurgitation
  • Chronic diarrhea or constipation

These symptoms could be temporary health concerns or signs of a serious condition, so taking a proactive approach is key. AIMG’s specialists are well-versed in diagnosing and treating diseases and conditions of the digestive system with the utmost care and precision. Some of the conditions our medical facility treats are as follows:

Gastrointestinal reflux disease (GERD)

This is a condition that occurs when stomach acid flows back into the esophagus. It can cause heartburn, trouble swallowing, and other symptoms. Treatment may involve a healthy diet avoiding foods that trigger acid production, weight management, and/or medication.

Celiac disease

This is an auto-immune disorder that is triggered by the consumption of gluten (a protein found in wheat, barley, rye, and some other grains). It causes damage to the small intestine which leads to vitamin malabsorption and other symptoms. Managing this condition involves following a strict gluten-free diet and scheduling regular medical check-ins to monitor vitamin levels and symptoms.

Colon polyps

These are clusters of cells that form on the lining of the colon or rectum. Most are harmless and do not produce symptoms, but they can occasionally grow and develop into cancer. Regular screenings help to identify and remove any polyps that develop before they have the opportunity to become cancerous.

Peptic ulcers

Ulcers sometimes occur when stomach acid causes damage to the lining of the digestive tract. Common causes include a bacteria called H. Pylori or frequent use of anti-inflammatory pain relievers like aspirin, ibuprofen, or naproxen. Upper abdominal sensitivity and/or pain are the most common symptoms. This condition can be treated with medication or antibiotics, as needed.

Inflammatory bowel disease

This is a term that includes a number of GI disorders such as ulcerative colitis or Crohn’s disease that involve the ongoing inflammation of any part of the digestive tract. Symptoms can include abdominal cramping, rectal bleeding, diarrhea, fatigue, and weight loss. Treatment may include following a special diet, medication, and/or surgery.


This is a viral infection that causes inflammation of the liver, which sometimes leads to serious liver damage. It is spread through contaminated blood. Hepatitis C used to require weekly injections and oral injections, but thanks to modern medical developments, this condition is generally cured through a course of oral medications.

Liver disease

Liver disease refers to any of a number of conditions that cause damage to your liver. It can be caused by inherited conditions, infections, or overconsumption of alcohol and can lead to scarring and other serious complications. Symptoms can include abdominal pain, nausea, fatigue, bruising, swelling of the limbs, or changes in your urine or stool color. Complications of unmanaged liver disease can be serious, but many forms can be managed by lifestyle changes and medications.

Gastrointestinal Screening and Treatment Options

As part of RWJBarnabas Health, AIMG is able to facilitate the most advanced GI screening procedures with state-of-the-art tools and equipment in identifying and treating diseases of the GI system. Our medical facility offers screening and treatment options that include:

Endoscopic ultrasound

This examines the upper and lower GI tract and other organs.

pH Monitoring

Esophageal pH monitoring is used to measure the amount of acid backing up from the stomach into the esophagus as well as to measure the effectiveness of any prescribed medications that prevent acid reflux.

Upper endoscopy

This helps diagnose conditions of the esophagus, stomach, and small intestine.


This procedure is used to detect polyps and/or signs of cancer in the colon. We recommend this procedure for individuals over the age of 50.

Avenel Iselin Medical Group understands that living with a gastrointestinal disease can be challenging, but you aren’t alone. Ongoing developments in modern medicine and technology allow patients to live increasingly longer and more active lives. We believe that prevention is the best medicine, and AIMG is here for you every step of the way.
