Get to the root of your digestive issues with gut-brain therapy techniques that help you self-manage your gut symptoms in just 6-weeks.
IBS, functional dyspepsia, functional constipation, and functional heartburn are now classified as gut-brain disorders - conditions driven by miscommunication between the gut and brain. The same gut-brain dysfunction also explains why many people with IBD continue to experience pain, constipation, or diarrhea even when their disease is in remission.
When the gut and brain fail to communicate properly, the body can misinterpret normal digestive processes as pain or discomfort. This heightened sensitivity, known as visceral hypersensitivity, can make the gut more reactive and contribute to gastrointestinal symptoms.
Nerva combines evidence-based gut-brain therapy techniques with real human support to help you self-manage symptoms, rebuild confidence, and get back to living fully.
