Patient Recruitment

Acid reflux disease/peptic ulcers SmartPill® Study

Doctor speaks to a hospital patient.

Pill capsule

The SmartPill system - a laptop and another electronic device.

Do you suffer from acid reflux disease or peptic ulcers, or are you taking a stomach acid blocker with good results?

Stomach acid disorders are often difficult to diagnose and treat. A new method for determining gastric acid output using a wireless capsule, the SmartPill®, has been developed to measure acid levels, temperature, and pressure throughout the stomach, small intestine and colon. It requires swallowing a small capsule.

The National Institute of Diabetes and Digestive and Kidney Diseases at the National Institutes of Health Clinical Center in Bethesda, Maryland, is looking for patients to participate in a study that will measure stomach acid secretions using the SmartPill® to compare to other measurement methods. Participation will require 4 outpatient visits.

Compensation will be provided.

You may be eligible if you:

  • are 18 years of age or older
  •  have been diagnosed with gastroesophageal reflux, peptic ulcer, gastric hypersecretion disease, OR have medication-controlled gastroesophageal reflux, peptic ulcer or gastric hypersecretion disease

You may not be eligible if you have:

  • a history of stomach or gastric surgeries
  • trouble swallowing
  • any implanted or portable medical devices such as a pacemaker, or infusion pump
  • any uncontrolled medical or psychiatric conditions
