Effects of Chewing Gum on Glycaemic Control in Women With Gestational Diabetes

Eligible patients are randomized to receive either routine care (control group) or routine care in addition to a chewing gum intervention for five days (beginning with the second study day, i.e. the day after baseline examination): sugar-free, fruit or mint flavoured gum chewed three times daily for 20 minutes before each meal. Routine care includes standard dietary and lifestyle advice for 30 minutes following our local recommendations as well as an advice on capillary blood glucose measurement (fasting as well as 1h after starting each meal). Capillary blood glucose profiles are reevaluated seven days after starting the blood glucose monitoring. Study visits will be scheduled at screening (visit 1, where eligible patients were randomized) as well as seven days later (visit 2).
