ClinConnect Summary
This clinical trial is studying how different treatments for obesity affect women's health over time. The focus is on how these treatments influence nutrition, muscle strength, and reproductive health, as well as how they might impact pregnancy outcomes and child development. If you are a woman aged 18 to 55 with obesity (a body mass index of 30 or more) and are currently receiving treatment like bariatric surgery or anti-obesity medication, you might be eligible to participate.
If you join the study, you will help researchers by completing questionnaires and providing samples of blood, urine, and stool. You will also undergo tests to measure body composition and muscle strength, which may take place over a period of up to 10 years. This research aims to better understand the long-term effects of obesity treatment on women's health, ultimately leading to improved care and support for women facing these challenges.
