Scientists at Monash University in Melbourne, Australia have developed a hypnotherapy-based computer app to help people with IBS (irritable bowel syndrome). 

The program called Nerva guides users through a ten-minute hypnotherapy session every day for six weeks.  The neural therapy is designed to correct the disordered signaling from brain to gut.  Patients who complete the six-week program report a reduction in symptom severity from 67 (on a scale of 100) to 39.  Adding a low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet has additional benefit.
