Why Would You Need To See Your Gastroenterologist?

The gastrointestinal tract encompasses many functions and organs, not only the stomach and intestines as it's often believed, so they require a specialist with a deep understanding of these systems who can help when you are struggling with more than a common stomach ache. You can reach out to your Hawaii gastroenterologist, Dr. Stephen Buto in Honolulu, HI, who can guide you to the most effective treatment based on your needs.

Abdominal Pain

When is a stomach ache more than just a common stomach ache? Just about everyone experiences occasional abdominal pain and it is typically nothing to be overly concerned about, it often simply means a change to one's diet is necessary. But if the pain is severe or recurring, or is accompanied by painful bowel movements or nausea then you may need a gastroenterologist for help.


The same is the case with occasional heartburn, but if you find yourself reaching for over-the-counter heartburn medication on a regular basis then you should consider seeing a specialist. Frequent heartburn could be caused by a condition called gastroesophageal reflux disease (GERD) or even possibly esophageal cancer, which may require further diagnosis and treatment from your gastroenterologist.

Abnormal Bowel Movements

Whether it's constipation, diarrhea, or rectal bleeding, the same principle above applies, the problem could be brought on by issues with your diet, but if these recur or are severe then it's time to seek professional help.


For most people, the time to begin regular screenings for colorectal cancer begins at age 50, although the exact age can vary depending on factors like ethnicity and past health history. Colorectal cancer can be very highly treatable if caught early but early signs typically need to be spotted during a screening as the symptoms of the disease can mean cancer has already begun to advance.
