ClinConnect Summary

This clinical trial is studying the nasal environment in people who are obese compared to those who are lean. The goal is to understand how the nasal area might play a role in obesity and help improve treatments for those who struggle with weight issues. The study is currently recruiting participants, and they are looking for adults between the ages of 18 and 55 who meet certain criteria related to their body weight. Specifically, they need 50 participants with obesity (a body mass index, or BMI, over 30), 50 lean participants (BMI between 18 and 25), and 50 obese patients who are scheduled for weight loss surgery (BMI over 35).

To participate, individuals must provide written consent and meet the age and BMI requirements. However, there are some exclusions, such as smokers, those with certain sinus issues, or individuals with severe chronic diseases. Participants can expect to undergo assessments related to their nasal environment, which may include simple tests and questionnaires. The information gathered may help researchers better understand the relationship between nasal health and obesity, potentially leading to new ways to support weight management in the future.
