Then, when she relocated to the shore, she found a similar world-class approach at Atlantic Gastroenterology Associates. She’s been here ever since, and has enjoyed every minute of her 33 years.

As head of the non-invasive GI diagnostics area of AGA, Ms. Fietkiewicz oversees the procedures that help physicians determine treatment. The Hydrogen Breath Test measures lactose and fructose intolerance. The H-Pylori Test investigates whether a germ is causing inflammation and/or ulcers. The Restech Studies determine whether a person’s stomach acid is rising high into the throat. The Small Bowel and Esophageal Capsule Studies detect presence of disease. Ms. Fietkiewicz guides patients from start to finish through these tests, reassuring and coaching whenever needed, so they will be as comfortable with the procedures as possible.
