Brain causes of nausea, vomiting, and low energy

Official title: Neural Mechanisms of Nausea, Vomiting, and Energy Dysregulation

Funded at University of Pennsylvania · NIH-11330553 · Data updated 2026-11-12

This project tests whether targeting brain circuits that cause nausea can reduce vomiting and improve energy for people taking diabetes, obesity, or cancer medications.

Who could benefit from this research

Could help

People who experience severe nausea or vomiting while taking GLP-1 medications for diabetes or obesity, or during chemotherapy, would be the most relevant candidates for future trials.

Less likely to help

People whose nausea is caused by motion sickness, vestibular disorders, or unrelated gastrointestinal diseases may not benefit from this approach.

What this research studies

From a patient perspective, the team is mapping how gut hormones and specific brain receptors trigger nausea and vomiting using modern genetic tools and animal models. They focus on nausea caused by GLP-1 drugs used for diabetes and obesity and by chemotherapy, which often leaves patients malnourished and exhausted. By identifying the neurons and signaling pathways involved, the researchers aim to find targets that could be treated to prevent or lessen these side effects without blocking the benefits of the original medications. Right now the work is preclinical, but it is intended to guide future treatments and clinical trials to help patients keep their appetite and strength.

Why it matters

Potential benefit: If successful, this work could lead to therapies that reduce nausea and vomiting from GLP-1 medications and chemotherapy, helping patients maintain nutrition and quality of life.

How similar studies have gone: Existing antiemetics help some patients but often leave residual symptoms, and targeting central GIP receptor pathways as a way to reduce nausea is a relatively new and not yet proven approach.
