ClinConnect Summary

This clinical trial is looking at how different types of meals and physical activity affect the way food moves through the stomach in healthy individuals. This is important because understanding gastric emptying can help doctors prevent complications during surgeries, especially the risk of food entering the lungs while a patient is under anesthesia. The study will use ultrasound to measure how full the stomach is in real-time, which is a safe and non-invasive method.

To participate in this trial, you need to be between 18 and 40 years old, able to provide consent, and willing to follow specific dietary guidelines before the study. You should not have any history of gastrointestinal diseases or recent abdominal surgeries. If you have certain medical conditions like obesity, diabetes, or are currently pregnant, you may not be eligible. Participants can expect to follow the study procedures, which will include dietary restrictions and activities designed to help researchers gather information about how your stomach processes food.
