Brain causes of nausea, vomiting, and low energy
Neural Mechanisms of Nausea, Vomiting, and Energy Dysregulation
This project tests whether targeting brain circuits that cause nausea can reduce vomiting and improve energy for people taking diabetes, obesity, or cancer medications.

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.
Who could benefit from this research
Good fit: 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.
Not a fit: People whose nausea is caused by motion sickness, vestibular disorders, or unrelated gastrointestinal diseases may not benefit from this approach.
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 performed: 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.
