Glucose is used throughout your body for energy. In order for your body to use glucose, It needs insulin, which is a hormone produced by your pancreas, that helps muscles, fat, and other cells absorb glucose for fuel. When you are pregnant your body naturally becomes more resistant to insulin, which means that more glucose remains in your blood. The Glucose Challenge Screening, is a standard preliminary screening test performed between 24-28 weeks to evaluate how your body processes sugar.  Exercise affects both glucose and insulin levels and this Q&A answers a question about whether working out prior to a glucose test will affect the results.
