This is a research study testing a smartphone app designed to help young people who have had stem cell transplants lose weight and develop healthier eating habits. The app uses an approach based on understanding addictive eating behaviors, and includes support from a coach who will check in with you regularly. The study lasts four months and involves three clinic visits, weekly phone calls, and daily text messages on weekdays.
Young stem cell transplant survivors often struggle with weight gain after their treatment, which can affect their long-term health.
