Brief Summary:
This study evaluates the feasibility and effect of probiotics on glycemic control in obese adolescents.

Condition or disease Intervention/treatment Phase
Obesity, Childhood Dietary Supplement: Vivomixx Dietary Supplement: Placebo Not Applicable

Detailed Description:

Diet-induced intestinal dysbiosis in obese children contributes to the development of type 2 diabetes mellitus (T2D). Probiotic treatment has been proposed to alleviate glycemic dysfunction and prevent/delay development of T2D. The investigators will test probiotics to improve insulin sensitivity and preserve beta cell function in obese children.

The probiotic strains are known to improve glycemic control.
