Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.

About this study

In plain language

This study tests whether newer tools measure body fat and muscle better than standard tools after weight-loss surgery. It is for adults with severe obesity who are scheduled for their first weight-loss surgery. The study also tracks muscle strength and compares body changes after two types of surgery.

Objectives The objective of this project is to generate pilot data substantiating our hypothesis that advanced body composition measurement tools will provide more accurate and clinically relevant data on the outcomes of metabolic surgery (MS) in patients with severe obesity compared to traditional methods. To achieve this objective, the investigators propose the following aims: Aim 1: Evaluate the effectiveness of different body composition measurement tools in assessing outcomes in patients with severe obesity undergoing MS. Aim 2: Assess the changes in body composition and muscle strength following MS. Aim 3: Compare body compositions changes between SG and RYGB patients.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Age 18 or older, male or female.
  • Have a BMI of 40 or higher. BMI is a measure of weight compared with height.
  • Weigh less than 440 pounds.
  • Willing to follow the study steps.
  • Scheduled for first-time weight-loss surgery: sleeve gastrectomy, which makes the stomach smaller, or Roux-en-Y gastric bypass, which changes the path food takes.

Who can't join

  • Have had weight-loss surgery or another complex belly surgery.
  • Have a medical or mental health condition that is not well controlled.
  • Are pregnant, trying to become pregnant, or breastfeeding.
  • Have metal objects in the body that may make MRI scan images unclear.
  • Have medical implants, such as a pacemaker or metal joint replacement.
  • Weigh more than 440 pounds.
  • Have a condition that may affect body fat and muscle measurements, such as advanced liver disease or severe heart or blood vessel disease.
  • Cannot understand the study’s risks, benefits, or rules for taking part.
