Gastroenterology is a specific branch of medicine which deals with the digestive tract. There are a number of reasons why you may need to see a gastroenterologist, and finding the best possible one is crucial for your health and safety.


In this guide, we will consider what gastroenterology is, when to see a gastroenterologist, and who are the best gastroenterologists (including those who accept Medicaid) in Pennsylvania.

What is a Gastroenterologist?

The term “gastroenterologist” comes from the latin root of “gastro,” meaning stomach, and “enterology,” which means the study of the intestines. A gastroenterologist is therefore a doctor who specializes in the digestive system, the gallbladder, the pancreas, the liver, and the bile ducts.


According to the American College of Gastroenterology (ACG) official website, for a person to become a gastroenterologist they must have:


●     Successfully completed a 3-year Internal Medicine residency

●     Gone through fellowship in gastroenterology following their residency


Below, we will consider different reasons why you may need to see a gastroenterologist. You can skip this next section to head over to the list of the best gastroenterologists in Pennsylvania state.

When Should I see a Gastroenterologist?

Conditions for which you would see a gastroenterologist include abdominal pains, digestive problems including bloating, constipation, and belching, colorectal cancer, or irritable bowel syndrome. You would also go see a gastroenterologist for a colonoscopy.

Abdominal Pains

According to the MedlinePlus government website, abdominal pain is defined as “pain that you feel anywhere between your chest and groin,” most notably in the ‘stomach’ area. Medline lists four main kinds of pain you may feel. These are:


●     Generalized pain

●     Localized pain

●     Camp-like pain

●     Colicky pain


These can be caused by a multitude of different factors, including constipation, food intolerance such as gluten or lactose intolerances, or the stomach flu. If you feel abdominal pain, drinking water, exercising, limiting foods which produce gas such as beans and legumes, eating small meals regularly, and eating lots of high-fiber foods can help. If the issues persist, you should consult a medical professional.


Digestive Problems

Digestive problems are any kind of problems dealing with the digestive, or gastrointestinal (GI), tract. The digestive tract includes the esophagus, stomach, intestines, liver, gallbladder, and pancreas. According to Medline, indicators of possible digestive problems include:


●     Bleeding

●     Bloating

●     Constipation

●     Diarrhea

●     Nausea/Vomiting

●     Incontinence

●     Troubles swallowing


These can be mild to severe issues which may or may not require seeing a medical professional. That being said, if you notice irregular digestive problems, or have issues which persist and impact your daily life, it is important to seek medical consultation immediately.


According to the Mayo Clinic, a colonoscopy is “an exam used to detect changes or abnormalities in the large intestine (coloc) and rectum.” Anyone over the age of 50 should receive a colonoscopy and anyone at risk of colon cancer. To get a colonoscopy you will need to see a gastroenterologist who will perform the exam.
