Prospero Health is a digital health initiative of Impact Obesity, an Australian health promotion charity. Prospero provides practical, evidence-based support for people navigating obesity treatment, including people using obesity management medications and people undergoing or recovering from bariatric surgery. Prospero Health is designed to work alongside existing healthcare. It helps users track symptoms, appetite and mood, understand patterns over time, access evidence-based health information and prepare for conversations with their healthcare team. Prospero Health does not replace individual medical advice, diagnosis or treatment from qualified healthcare professionals. Impact Obesity works to improve access to evidence-based obesity care and support in Australia.
