Researchers want to understand how the body digests protein after two common types of weight loss surgery: Roux-en-Y bypass and sleeve gastrectomy. This is especially important in older adults, because protein is crucial for maintaining muscle mass as we age. This study will use special tracers in a test meal to measure exactly how well your body breaks down and absorbs protein.
Weight loss surgery changes how the stomach and intestines work, which may affect how your body absorbs protein from food. Older adults are at higher risk of losing muscle mass after surgery, so doctors need to understand whether protein digestion problems are contributing to this issue.

You would visit the research center to eat a special test meal that contains tracers (safe markers) to measure protein digestion. Researchers will take samples to track how these tracers move through your body and how well you absorb the protein. The study compares people who had different types of weight loss surgery with those who haven't had surgery, and it also looks at differences between older and younger adults.
