Eligibility Criteria

Age22 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Prior completion of at least two months in a diet, exercise and lifestyle intervention program within the past two years
  • Fasting plasma glucose \>90 mg/dl plus 2-hour glucose ≥140 mg/dl on 75 gm OGTT plus HbA1C ≤7.0%. There is no lower limit for the A1C and no upper limit for the OGTT 2-hour glucose based on prior studies that allow us to identify people with falling β-cell function
  • Age 22-65 years
  • Body mass index (BMI) 30-40 kg/m2
  • For participants with diabetes, known duration \<1 year
  • No history of use of antidiabetic medications except during pregnancy

You may not qualify if:

  • Contraindications to LapBand(see Appendix 1)
  • Contraindication to MRI (claustrophobia; permanent metal objects such as pacemakers, prostheses, aneurysm clips)
  • Underlying disease(s) likely to (a) limit life span to less than study duration and/or (b) increase risk of intervention outside of the study and/or (c) limit ability to participate in outcomes assessment and/or (d) limit participation
  • An underlying disease known to have important effects on glucose metabolism
  • Active infections
  • Renal disease (serum creatinine ≥1.4 mg/dl for men; ≥1.3 mg/dl for women) or serum potassium abnormality (\<3.4 or \>5.5 mmol/l)
  • Anemia (hemoglobin \<11g/dl in women, \<12 g/dl in men) or known coagulopathy
  • Cardiovascular disease, including uncontrolled hypertension and symptomatic congestive heart failure. Participants must be able to safely tolerate administration of fluid/volume challenges during clamp studies.
  • Serum AST \>3 times upper limit of normal in local clinical lab
  • Excessive alcohol intake
  • Suboptimally treated thyroid disease
  • Conditions or behaviors likely to affect the conduct of the study
  • unable or unwilling to give informed consent
  • unable to adequately communicate with clinic staff
  • another household member is a participant or staff member
  • +5 more criteria
