Our goal is to investigate how hormones that control blood sugar, hunger, and stomach emptying change with puberty and being overweight. These substances change with a meal.

  • For this, we need to compare lean and overweight children.
  • We need to study them before and during puberty.
  • All children in the study will be tested before and after a liquid meal.


Study Type: Observational
Study Design: Observational Model: Case Control

Primary Outcome Measures:
  • Overweight and Lean Children Sugar Metabolism Before and During Puberty [ Time Frame: 4 hours ]
    Too much weight gain can cause changes in the substances that control blood sugar and hunger in the body. Scientists need to compare these substances in lean and overweight children before and during puberty. These substances can be measured before and after a meal in the blood and in the urine. The way your stomach moves food can change your sugar levels. We want to understand how diabetes develops by studying these things. This can help find better ways to prevent and treat diabetes.
