Understanding fat tissue characteristics in type 2 diabetes and obesity

Regional Adipose Tissue Characteristics in Type II Diabetes

Concordia University, Montreal · NCT06599047

This study looks at the different types of fat in people with obesity, type 2 diabetes, and those who are lean to see how they affect health and each other.

What this trial studies

This observational study aims to investigate the characteristics of adipose tissue in individuals with obesity, type 2 diabetes, and lean individuals. It will recruit 140 participants aged 18-65, dividing them into three groups: those with obesity, those with diabetes, and lean individuals. The study will focus on how abdominal fat contributes to metabolic diseases and how these diseases may affect fat tissue. Participants will be recruited from a hospital in Montreal, specifically those awaiting bariatric or general abdominal surgery.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 18-65 who are either obese and anticipating bariatric surgery or lean individuals awaiting general abdominal surgery.

Not a fit: Patients with uncontrolled hypothyroidism, renal impairment, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the mechanisms linking adipose tissue characteristics to type 2 diabetes and obesity, potentially leading to improved treatment strategies.

How similar studies have performed: While there have been studies on adipose tissue and metabolic diseases, this specific approach to understanding the mechanisms in bariatric patients is relatively novel.
