FASTING

This study looks at whether eating solid food before a WALANT procedure (a type of hand surgery using only local anesthesia) can reduce anxiety and nausea compared to fasting. Researchers will randomly assign 134 participants to either eat or fast before their surgery and then co…

This study investigates what happens inside the body after an 84-hour fast. Researchers will measure peak fat oxidation (how well the body burns fat during exercise), mitochondrial coupling (energy efficiency in cells), and changes in the extracellular matrix (the scaffold around…

This study looks at how a 36-hour water-only fast changes immune cells in healthy young men. Four participants will have blood drawn before, during, and after fasting to measure immune markers. It's a very small, early-stage trial aimed at understanding, not treating, any conditi…

This study looks at whether stopping tube feeding for at least 8 hours before a procedure helps or harms recovery in critically ill patients on breathing machines. About 1,072 adults in the ICU will be randomly assigned to either fast or continue feeding until right before their …

This study looks at what happens to your immune cells when you fast for 24 hours. Researchers want to understand how the body's switch from using sugar to burning fat for energy changes the way immune cells work. The study involves 28 healthy adults aged 18-40. No treatment or dr…

This study looks at how different amounts of clear liquids (like water or juice) affect stomach contents in teens aged 13-17 before an upper GI endoscopy. Participants are randomly assigned to drink 3, 5, 7, or 10 ml of clear fluid per kilogram of body weight two hours before the…

This study looks at whether ultrasound can reliably measure how much is in a child's stomach before surgery, which could help prevent rare but serious complications like breathing in stomach contents. About 60 children aged 2 to 18 will have stomach ultrasounds, and some will als…

This study looks at whether patients with severe breathing problems in the ICU should be allowed to eat or drink before they need a breathing tube. Currently, patients are often kept fasting to prevent food from entering the lungs, but this can cause discomfort and malnutrition. …
