Why should I turn to a gastroenterologist?

If you’ve been dealing with gastrointestinal issues and you’ve talked with your primary doctor already then they may have referred you to us; however, there are many reasons people turn to our team here in Honolulu, HI. If you are dealing with persistent bowel changes, unexplained abdominal pain, or you have a family history of colon cancer then turning to us can give you the answers and care you need. Even if you aren’t dealing with issues, you can and should turn to us for colon cancer screenings by the time you turn 50 years old.

When should I see a doctor about my acid reflux?

Acid reflux is a common issue; however, if you are experiencing severe or persistent bouts of acid reflux two or more times a day then it’s time to turn to a gastroenterologist who can determine the root cause of your symptoms and also help you manage them.

Whether you have a family history of colon cancer or not, every individual should come in for routine colon cancer screenings, or a colonoscopy, by the time they turn 50. Men and women at an increased risk for colorectal cancer should talk to our gastroenterologist about getting screened by age 45.
