People with functional dyspepsia – also known as indigestion – often have belly pain, nausea, lots of belching, and other GI symptoms after eating.
Although VR improved symptoms of indigestion, researchers still do not know exactly how it works. There are some theories: Immersion in a different world distracts people from belly pain. VR also could change the signals sent between the brain and the gut, thereby easing discomfort and pain, Cangemi says.
But these agents can cause side effects, Cangemi says."Therefore, novel safe and effective treatment options for functional dyspepsia are greatly needed." People filled out questionnaires to report pain and quality of life at the beginning of the study and to track any changes at week 1 and week 2. Although symptoms got less severe in both groups at 2 weeks, people in the VR group improved significantly more on the standard symptom severity scale.
Limits of the study include a small number of participants and its short, 2-week duration. The researchers plan to study VR in a more people with functional dyspepsia and for a longer time. They would also like to compare improvements between VR and medications taken to ease symptoms and/or determine if combining the technology and the medicines results in even greater improvements.
